Surgical aortic valvuloplasty is a better primary intervention for isolated congenital aortic stenosis in children with bicuspid aortic valve than balloon aortic valvuloplasty. Hellenic J Cardiol 2024; 77:54-62. [PMID: 37269944 DOI: 10.1016/j.hjc.2023.05.012] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/19/2023] [Revised: 05/09/2023] [Accepted: 05/30/2023] [Indexed: 06/05/2023] Open
Abstract
OBJECTIVES Surgical aortic valvuloplasty (SAV) and balloon aortic valvuloplasty (BAV) are two main treatments for children with isolated congenital aortic stenosis (CAS). We aim to compare the two procedures' midterm outcomes, including valve function, survival, reintervention, and replacement. METHODS From January 2004 to January 2021, children with isolated CAS undergoing SAV (n = 40) and BAD (n = 49) at our institution were included in this study. Patients were also categorized into subgroups based on the aortic leaflet number(Tricuspid = 53, Bicuspid = 36) to compare the two procedures' outcomes. Clinical and echocardiogram data were analyzed to identify risk factors for suboptimal outcomes and reintervention. RESULTS Postoperative peak aortic gradient (PAG) and PAG at follow-up in the SAV group were lower compared with the BAV group (p < 0.001, p = 0.001, respectively). There was no difference in moderate or severe AR in the SAV group compared with the BAV group before discharge (5.0% vs 12.2%, p = 0.287) and at the last follow-up (30.0% vs 32.7%, p = 0.822). There were no early death but three late deaths (SAV = 2, BAV = 1). Kaplan-Meier estimated survivals were 86.3% and 97.8% in SAV and BAV groups respectively at 10 years (p = 0.54). There was no significant difference in freedom from reintervention (p = 0.22). For patients with bicuspid aortic valve morphology, SAV achieved higher freedom from reintervention (p = 0.011) and replacement (p = 0.019). Multivariate analysis indicated that residual PAG was a risk factor for reintervention (p = 0.045). CONCLUSIONS SAV and BAV achieved excellent survival and freedom from reintervention in patients with isolated CAS. SAV performed better in PAG reduction and maintenance. For patients with bicuspid AoV morphology, SAV was the preferred choice.

Abstract
Aortic regurgitation (AR) is common after aortic balloon valvuloplasty in children and it has been associated with large balloon/annulus ratio, abnormal valve morphology and aortic valve prolapse. We present a rare case of severe AR after aortic balloon valvuloplasty due to aortic strands rupture, causing prolapse of the co-joined cusp. These findings were identified by 3D echocardiography, highlighting the importance of this imaging technique even in pediatric patients.

Abstract
BACKGROUND Valve repair is the procedure of choice for congenital aortic valve disease. With increasing experience, the surgical armamentarium broadened from simple commissurotomy to more complex techniques. We report our 30-year experience with pediatric aortic valve repair. METHODS A retrospective chart review of all patients aged less than 18 years who underwent aortic valve repair from May 1985 to April 2020 was conducted. Mortality was cross-checked with the national health insurance database (96% complete mortality follow-up in April 2020). Primary study endpoints were survival and incidence of reoperations. RESULTS From May 1985 until April 2020, 126 patients underwent aortic valve repair at a median age of 1.8 years (interquartile range, 0.2-10). Early mortality was 5.6% (7 of 126). All early deaths occurred in neonates with critical aortic stenosis undergoing commissurotomy. No early deaths were observed after 2002. Kaplan-Meier estimated survival was 90.8% (95% CI, 84.0-94.8) at 10 years, 86.9% (95% CI, 78.7-92.2) at 20 years, and 83.5% (95% CI, 71.7-90.6) at 30 years. The cumulative incidence of aortic valve replacement was 37% (95% CI, 27.7-46.3) at 10 years, 62.2% (95% CI, 50.1-72.1) at 20 years, and 67.4% (51.2-79.2) at 30 years. Nine patients had undergone re-repair of the aortic valve. The majority of valve replacements were Ross procedures. CONCLUSIONS Our results support a repair-first strategy for patients with congenital heart disease and underline that aortic valve reconstruction can be a successful long-term solution. Longevity did not differ between aortic valve commissurotomy and complex aortic valve reconstruction.

Bicuspid Aortic Valve in Children and Adolescents: A Comprehensive Review. Diagnostics (Basel) 2022; 12:diagnostics12071751. [PMID: 35885654 PMCID: PMC9319023 DOI: 10.3390/diagnostics12071751] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/18/2022] [Revised: 07/12/2022] [Accepted: 07/19/2022] [Indexed: 11/16/2022] Open
Abstract
Bicuspid aortic valve (BAV) is the most common congenital heart defect. Prevalence of isolated BAV in the general pediatric population is about 0.8%, but it has been reported to be as high as 85% in patients with aortic coarctation. A genetic basis has been recognized, with great heterogeneity. Standard BAV terminology, recently proposed on the basis of morpho-functional assessment by transthoracic echocardiography, may be applied also to the pediatric population. Apart from neonatal stenotic BAV, progression of valve dysfunction and/or of the associated aortic dilation seems to be slow during pediatric age and complications are reported to be much rarer in comparison with adults. When required, because of severe BAV dysfunction, surgery is most often the therapeutic choice; however, the ideal initial approach to treat severe aortic stenosis in children or adolescents is not completely defined yet, and a percutaneous approach may be considered in selected cases as a palliative option in order to postpone surgery. A comprehensive and tailored evaluation is needed to define the right intervals for cardiologic evaluation, indications for sport activity and the right timing for intervention.

Balloon aortic valvuloplasty in neonates: short- and long-term effects and predictors of successful outcome. Adv Cardiol 2022; 18:154-161. [PMID: 36051839 PMCID: PMC9421511 DOI: 10.5114/aic.2022.118532] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/27/2021] [Accepted: 06/11/2022] [Indexed: 11/17/2022]
Abstract
Introduction Balloon aortic valvuloplasty (BAV) is a common treatment method of aortic valve (AV) stenosis in neonates. Long-term BAV effects are suboptimal, and their predictors are not well acknowledged. Aim To identify predictors of suboptimal short- and long-term BAV results. Material and methods The study group comprised forty-three neonates (8 females; weight 3.34 ±0.56 kg) who underwent BAV between 1998 and 2021. Seventeen patients (39.53%) had critical AV stenosis. AV was bicuspid in 22 patients, tricuspid in 12, unicuspid in 2, and undefined in 7 patients. The mean balloon/annulus ratio was 0.9 ±0.07. Catheterization, clinical, and follow-up data were analysed. Results The peak-to-peak gradient decreased from 67.5 ±26.3 to 21.3 ±12.6 mm Hg. Twenty-eight patients (65.1%) had adequate early outcome. Aortic regurgitation (AR) occurred in 13 (30.2%) patients. No predictors of inadequate early outcome were found. Twenty-year survival was 90.7%. Eleven (35.5%) patients underwent reintervention at a median of 12 (1–215) months; BAV in 5 patients, surgical valvuloplasty in 2, Ross operation in 2, AV replacement in 1, and Norwood operation in 1 patient. Fifteen-year freedom from reintervention (FFR) was 48%. Adequate early outcome resulted in higher FFR (71% vs. 22%), and so did no significant AR (60% vs. 30%). Conclusions BAV provides satisfying early results. AR remains a significant aftermath of BAV. Risk factors and procedural techniques improving the outcome of BAV are unclear. Further research is needed to improve FFR.

Abstract
Supplemental Digital Content is available in the text. Background: Aortic valve stenosis is the most common type of congenital left ventricular (LV) outflow tract obstruction. Balloon aortic valvuloplasty (BAV) has become the first-line treatment pathway in many centers. Our aim was to assess the trajectory of LV remodeling following BAV in children and its relationship to residual aortic stenosis (AS) and insufficiency (AI). Methods: Children <18 years of age who underwent BAV for isolated aortic stenosis from 2004 to 2012 were eligible for inclusion. Those with AI before BAV, other complex congenital heart lesions, or <2 accessible follow-up echocardiograms were excluded. Baseline and serial echocardiographic data pertaining to aortic valve and LV size and function were retrospectively collected through December 2017 or the first reintervention. Longitudinal data was assessed using per-patient time profiles with superimposed trend lines using locally estimated scatterplot smoothing. Associations with reintervention or death were also evaluated. Results: Among the 98 enrolled children, the median (interquartile range) age at BAV was 2.8 months (0.2–75). The median (interquartile range) follow-up was 6.8 years (1.9–9.0). Children with predominantly residual AI (n=11) demonstrated progressive increases in their LV end-diastolic dimension Z score within the first 3 years after the BAV, followed by a plateau (P<0.001). Their mean LV circumferential and longitudinal strain values remained within the normal range but lower than in the non-AI group (P<0.001 and P=0.001, respectively). Children with predominantly residual aortic stenosis (n=44) had no changes in LV dimensions but had a rapid early increase in mean LV circumferential and longitudinal strain. The cumulative proportion (95% CI) of reintervention at 5 years following BAV was 33.7% (23.6%–42.4%). Conclusions: Our study demonstrates that LV remodeling occurs mainly during the first 3 years in children with predominantly residual AI after BAV, with no subsequent significant functional changes over the medium term. These data improve our understanding of expected patient trajectories and thus may inform decisions on the timing of reintervention.

Abstract
Transcatheter balloon valvuloplasty for the treatment of aortic and pulmonary valve stenosis was first described nearly 40 years ago. Since that time, the technique has been refined in an effort to optimize acute outcomes while reducing the long-term need for reintervention and valve replacement. Balloon pulmonary valvuloplasty is considered first-line therapy for pulmonary valve stenosis and generally results in successful relief of valvar obstruction. Larger balloon to annulus (BAR) diameter ratios can increase the risk for significant valvar regurgitation. However, the development of regurgitation resulting in right ventricular dilation and dysfunction necessitating pulmonary valve replacement is uncommon in long-term follow-up. Balloon aortic valvuloplasty has generally been the first-line therapy for aortic valve stenosis, although some contemporary studies have documented improved outcomes following surgical valvuloplasty in a subset of patients who achieve tri-leaflet valve morphology following surgical repair. Over time, progressive aortic regurgitation is common and frequently results in the need for aortic valve replacement. Neonates with critical aortic valve stenosis remain a particularly high-risk group. More contemporary data suggest that acutely achieving an aortic valve gradient <35 mm Hg with mild aortic regurgitation may improve long-term valve performance and reduce the need for valve replacement. Continued study will help to further improve outcomes and reduce the need for future reinterventions.

Abstract
BACKGROUND For children with congenital aortic stenosis (AS) who are candidates for biventricular repair, valvuloplasty can be achieved by surgical aortic valvuloplasty (SAV) or by transcatheter balloon aortic dilation (BAD). We aimed to evaluate the longer term outcomes of SAV versus BAD at our institution. METHODS We retrospectively reviewed the outcomes of 2 months to 18 years old patients who underwent SAV or BAD at our institution between January 1990 and July 2018. Baseline and follow-up characteristics were assessed by echocardiography. Long-term survival, freedom from reintervention, freedom from aortic valve replacement (AVR), and aortic regurgitation were evaluated. RESULTS A total of 212 patients met inclusion criteria (SAV = 123; BAD = 89). Age, sex, aortic insufficiency (AI), and aortic valve gradient were similar between the groups. At 10 years, 27.9% (19/68) of SAV patients and 58.3% (28/48) of BAD patients had moderate or worse AI (P = .001), and reintervention occurred in 39.2% (29/74) of SAV patients and 78.6% (44/56) of BAD patients (P < .001). Kaplan-Meier analysis revealed overall survival was 96.8% (119/123) for SAV and 95.5% (85/89) for SAV (P = .87). At 10 years, 35% (23/66) of SAV patients and 54% (23/43) of BAD patients underwent AVR (P = .213). CONCLUSIONS Surgical aortic valvuloplasty demonstrated greater gradient reduction, less postoperative and long-term AI, and a lower reintervention rate at 10 years than BAD. There was no difference in survival or AVR reintervention rate. Surgical aortic valvuloplasty is a durable and efficacious intervention and should continue to be considered a favorable choice for palliation of valvular AS.

Abstract
OBJECTIVE Rapid right ventricular pacing during balloon aortic valvuloplasty is commonly used to achieve balloon stability in children and adults. There is no consensus for the use of the technique in neonates and infants. We sought to review our institutional experience with rapid right ventricular pacing-assisted balloon aortic valvuloplasty across all age groups and evaluate the safety and effectiveness of the technique in the sub-group of neonates and infants <12months. METHODS Retrospective study between February, 2011 and February, 2020. RESULTS A total of 37 patients (Group I: 21 neonates/infants <12months and Group II: 16 children 12 months-16 years) were analysed. Catheter-measured left ventricular to aortic gradient reduced from median of 66 mmHg (with a range from 30 to 125 mmHg) to 14 mmHg (with a range from 5 to 44 mmHg) in Group I and 44 mmHg (with a range from 28 to 93 mmHg) to 18 mmHg (with a range from 2 to 65 mmHg) in Group II (p < 0.001). Procedure and fluoroscopy times were identical in the two groups. Balloon:annulus ratio was 0.94 and 0.88 in Groups I and II, respectively. Freedom from reintervention was 100% for Group I at a median time of 3.2 years and 81% at 2.7 years for Group II. Reinterventions in Group II (3/16 pts) were performed predominantly for complex left ventricular outflow tract stenosis. At follow-up echocardiogram, 45% of patients in Group I had no aortic regurgitation, 30% trace-mild, 20% mild-moderate, and 5% moderate aortic regurgitation, whereas in Group II, 50% of patients had no aortic regurgitation, 32% had mild aortic regurgitation, and 18% mild-moderate aortic regurgitation. Unicuspid valves were only encountered in Group 1 (2/21 pts, 10%) and they were predictive of mild-aortic regurgitation during follow-up (p = 0.003). Ventricular fibrillation occurred in three neonates with suspicion of myocardial ischemia on the pre-procedure echocardiogram. All were successfully defibrillated. CONCLUSIONS Rapid right ventricular pacing can be expanded in neonates and infants to potentially decrease the incidence of aortic regurgitation and reintervention rates, hence avoiding high-risk surgical bail-out procedures for severe aortic regurgitation in the first year of life. Myocardial ischemia may predispose to ventricular dysrhythmias during rapid right ventricular pacing.

Abstract
Background Left ventricular (LV) dysfunction in patients with aortic valve stenosis (AVS) is seen in two scenarios: in neonates and in elderly patients. Neonatal AVS may present as a congestive cardiac failure (CCF), while older children rarely present with CCF if they have not been diagnosed early. Only a few reports of LV dysfunction with AVS have been described in the literature. However, there is a paucity of data regarding the safety and effectiveness of balloon aortic valvuloplasty (BAV) in children with AVS with LV dysfunction. Therefore, the aim of this study was to evaluate outcomes to establish the safety and effectiveness of BAV in children with AVS and LV dysfunction in improving LV function and survival. Methods A total of 160 BAVs were performed from 2004 to 2017; of these, 41 (25.6%) patients had LV dysfunction. We reviewed these cases, and data were obtained on clinical features, echocardiographic parameters including LV ejection fraction (LVEF) and LV dimensions, LV posterior wall, interventricular septal thickness, pressure gradient across the valve, aortic valve morphology and annulus and aortic insufficiency (AI), and angiographic parameters such as aortic and LV pressures, AI and annulus size, and balloon size. Echocardiography was done before the procedure, one day after intervention, at three months, at six months, and on regular follow-up. Mortality during and after the procedure and at follow-up was reported. Results Children who had undergone BAV for AVS and LV dysfunction within the age range of six to 192 months showed a significant reduction in peak-to-peak pressure gradient (PPG) from 73.5 ± 30 mmHg to 26.7 ± 6.7 mmHg and improvement in LVEF from 32.8 ± 11% to 54.3 ± 12.7% after 24 hours. Instantaneous gradient on echocardiography after three months showed PPG was 29.8 ± 7.7 mmHg and mean LVEF was 63 ± 8.6%. Mean LV end-diastolic pressure was 20.8 ± 4.7 mmHg and decreased to 13 ± 2.4 mmHg. Four patients died, all of whom had severe LV dysfunction - one died during the procedure and three died within six to 20 hours after successful BAV. On average follow-up of 6.4 ± 3.8 years, with a range of three months to 13 years, there was no mortality, pressure gradient increased to 40 ± 16.3 mmHg (range, 20 to 90 mmHg), and three had BAV after one, four, and six years, respectively. There was an increase in AI from mild to moderate in five patients, but they did not require any intervention. Four patients had aortic valve replacement (AVR) with two patients having an increase in pressure gradient and AI after eight and 13 years, respectively. One patient had AI (+3) after BAV had AVR after three years, and one patient who had a very thick and dysplastic aortic valve with LVEF of 20% and pulmonary hypertension (PH) had AVR after six months. Conclusion Patients with AVS who develop LV dysfunction deteriorate and die soon without treatment. Our data suggest that BAV in children with aortic stenosis and LV dysfunction is safe and effective in the normalization of LV function.

Abstract
BACKGROUND Inflammatory is one of the main cause of aortic valve stenosis (AS), so discovering novel biomarkers for the targeted therapy of inflammation could be an attractive strategy in AS prevention. The objectives of our study were to clarify the modulatory role of resistin and silent information regulator 1 (SIRT1) before and after surgery and also to evaluate the therapeutic effects of resveratrol. METHODS Nineteen AS patients and 15 healthy subjects were studied as the case and control groups, respectively. Peripheral blood mononuclear cells (PBMCs) were isolated and cultured to determine the levels of resistin and SIRT1 and the effects of resveratrol on them. RESULTS Significant increase in resistin expression was observed in the patients compare to the control (p ≤0.01), and this upregulation was augmented 72 h following surgery (p ≤0.01). The SIRT1 expression decreased in the AS group compare to the control but this reduction was not significant. Aortic valve replacement caused a higher decrease in the protein (p ≤0.01) and mRNA level (p ≤0.05) of SIRT1. Resveratrol in the AS group significantly diminished the resistin level (p ≤0.05) but increased the SIRT1 level (p ≤0.001). CONCLUSIONS In our patients with AS, the resistin level was increased, whereas the expression of SIRT1 was reduced and surgery augmented these alterations. Resveratrol improved inflammation in the PBMCs of the patients through the SIRT1/resistin pathway. These findings suggest that pharmacological therapy with resveratrol might be a novel approach to alleviating inflammation in patients with AS.

Abstract
Abstract
Cardiac emergencies in children represent an extremely important issue in medical practice. In general, interventional treatment could be optional in many situations, however it can be indicated in emergency conditions. There are many diseases at pediatric age that can benefit from interventional treatment, thus reducing the surgical risks and subsequent complications. Balloon atrioseptostomy, patent ductus arteriosus (PDA) closure, percutaneous or hybrid closure of a ventricular septal defect, pulmonary or aortic valvuloplasty, balloon angioplasty for aortic coarctation, implantation of a stent for coarctation of the aorta, for severe stenosis of the infundibulum of the right ventricle, or for PDA correction are among the procedures that can be performed in emergency situations. This review aims to present the current state of the art in the field of pediatric interventional cardiology.

Abstract
The bicuspid aortic valve, a kind of heart disease that comes from parents, has been paid attention around the world. Although most bicuspid aortic valve (BAV) patients will suffer from some complications including aortic stenosis, aortic regurgitation, endocarditis, and heart dysfunction in the late stage of the disease, there is none symptom in the childhood, which restrains us to diagnose and treatment in the onset phase of BAV. Hemodynamic abnormalities induced by the malformations of the valves in BAV patients for a long time will cause BAV-associated aortopathy: including progress aortic dilation, aneurysm, dissection and rupture, cardiac cyst and even sudden death. At present, preventive surgical intervention is the only effective method used in this situation and the diameter of the aorta is the primary reference criterion for surgery. And the treatment effects are always not satisfactory for patients and clinicians. Therefore, we need more methods to evaluate the progression of BAV and the surgery value and the appropriate intervention time by combining basic research with clinical treatment. In this review, advances in morphology, genetic, biomarkers, diagnosis and treatments are summarized, which expects to provide an update about BAV. It is our supreme expectations to provide some evidences for BAV early screening and diagnosis, and in our opinion, personalized surgical strategy is the trend of future BAV treatment.

Abstract
BACKGROUND Aortic stenosis has been reported to manifest a slow rate of progression in mild disease, with a greater likelihood of progression in patients with moderate-severe disease. The natural history of the Doppler-estimated maximum gradient (DEMG) in patients after balloon aortic valvuloplasty (BAVP) has not previously been studied on a large scale. METHODS AND RESULTS A retrospective review was performed of 360 patients from 1984 to 2012 with aortic stenosis, providing a total of 2059 echocardiograms both before and after BAVP. Patients were excluded if they had an intervention within the first 30 days of life. The relationships between the aortic stenosis DEMG and several predictors (age at initial study, body surface area, valve morphology, and initial DEMG) were explored using linear mixed effect models. Patients with a unicommissural aortic valve had a significantly higher rate of progression compared with those with a bicommissural aortic valve (0.81 and 0.45 mm Hg/year; P<0.001). The median rate of progression in the post-BAVP group was significantly lower than the median pre-BAVP rate of progression (n=34; pre-BAVP 3.97 [1.69-8.7] mm Hg/year; post-BAVP 0.40 [-1.80 to 3.88] mm Hg/year; P<0.008). When adjusted for body surface area, there was no significant increase in the DEMG (-0.03 mm Hg/m2 per year; P<0.001). CONCLUSIONS There is a statistically significant increase in the DEMG over time in patients with aortic stenosis. After balloon dilation, the DEMG rate of change is reduced compared with that pre-dilation. Given the effect of body surface area on DEMG progression, more frequent observation should be made during periods of rapid somatic growth.

Abstract
BACKGROUND Surgical or percutaneous interventional treatment of severe congenital aortic valve stenosis (CAS) in early infancy remains challenging. This single-center, retrospective study analyzed midterm outcomes of a hybrid balloon valvuloplasty procedure through the ascending aorta by way of median sternotomy, including cases with improved technique. METHODS Included were 45 consecutive infants (aged <90 days) with CAS and selected for biventricular repair who underwent hybrid balloon valvuloplasty in a hybrid or ordinary operating room from October 2010 to March 2016. Patients were assessed at 1, 3, 6, and 12 months and yearly thereafter. RESULTS Hybrid balloon valvuloplasty was successful in all patients, with the last 8 treated in an ordinary operating room under only echocardiography guidance with a new sheath. Thirty-two patients were successfully rescued from low heart rate or left ventricular systolic dysfunction, or both, by cardiac massage under direct visualization; none required cardiopulmonary bypass. The degree of new aortic insufficiency was mild in 7 patients and changed from mild to moderate in 1 patient. Aortic valve pressure gradient decreased from 70.6 ± 17.5 mm Hg preoperatively to 15.2 ± 4.2 mm Hg immediately postoperatively (p < 0.001). Fluoroscopy time was 4.8 ± 2.3 minutes. At a median of 32.1 months (range, 1 to 68 months) follow-up, all patients were alive and healthy. Aortic valve pressure gradient remained low (19.1 ± 5.2 mm Hg). Left ventricular ejection fraction increased from 0.515 ± 0.134 (range, 0.21 to 0.70) preoperatively to 0.633 ± 0.035 (range, 0.58 to 0.75; p < 0.001). No aortic insufficiency developed, and no patient required reintervention. CONCLUSIONS For infants with severe CAS, hybrid balloon valvuloplasty through the ascending aorta by way of a median sternotomy appears efficacious and safe up to midterm follow-up.

Abstract
Background The objective of this study was to examine early and long-term results of surgical aortic valvotomy in neonates and infants aged less than four months and to identify predictors of outcome. Methods Between August 1994 and April 2012, 83 consecutive patients younger than 4 months of age underwent open heart valvotomy for critical aortic stenosis in our institution. Median age was 17 days (range 0-111 days). We examined clinical records to establish determinants of outcome and illustrate long-term results. Results Fifty-six patients (67 %) were neonates. Associated cardiac malformations were found in 24 patients (29 %), including multilevel left heart obstruction in 5. The median follow-up was 4.2 years. The time-related survival rate was 87 and 85 % at 5 and 15 years, respectively. The time-related survival without reintervention was respectively 51, 35 and 18 % at 5, 10 and 15 years. The time-related survival without aortic valve replacement was respectively 67, 54 and 39 % at 5, 10 and 15 years. Ventricular dysfunction (p = 0.04), delayed sternal closure (p = 0.007), endocardial fibroelastosis (p = 0.02) and low z-score of the aortic annulus (p = 0.04) were found predictors of global mortality. Ventricular dysfunction (p = 0.01) and endocardial fibroelastosis (p = 0.04) were found predictors of reintervention. Conclusions The experience, in our center, on the management of critical aortic stenosis, shows a low early and late mortality, but the aortic valvotomy is a palliative procedure and we see unfortunately a high rate of reintervention among which the aortic valve replacement. These results suggest to reconsider the use of aortic balloon valvotomy, and particularly for the neonates with a low cardiac output in order to avoid the myocardial stress and the neurological injury due to the cardiopulmonary bypass.

Abstract
OBJECTIVES In this review, we will discuss aortic stenosis, aortic regurgitation, mitral regurgitation, and mitral stenosis. We will review the etiology, anatomy, pathophysiology, presentation, and treatment of aortic and mitral valve disease. Age and lesion specific treatments are outlined based on the severity of valve disease with an aim at long-term preservation of left ventricular function. DATA SOURCE MEDLINE and PubMed. CONCLUSIONS Mitral and aortic valve disease leads to unique hemodynamic burdens that can impact left ventricular function, quality of life, and longevity. The primary challenge in the management of mitral and aortic valve disease is to apply appropriate medical management and identify that point in time at which the surgery is necessary. Although guidelines have been established for the management of aortic and mitral valve disease in adults, the challenges of early presentation, maintenance of growth potential, and apparent increased tolerance of hemodynamic burden in children makes decision making challenging.

Abstract
Balloon aortic valvuloplasty (BAV) is a well accepted modality of treatment in congenital aortic stenosis in all age groups. Although in infants and children it is the modality of choice, in adolescents and young adults, it is of debatable efficacy. AIM To evaluate long-term results of aortic valvuloplasty particularly in adolescent and adults (>12 years) and compare the outcome in other age groups that are <1 year and between 1 are 11 years. SETTING Tertiary referral center. PATIENTS 165 consecutive patients treated at the median age of 9 years (1 day to 64 years). The follow-up was up to 14 years (median 3 years). The whole cohort was divided into 3 age-based subgroups: Group A (<1 year) n=45, Group B (1 year-11 years) n=52, and Group C (>12 years) n=68. The characteristics of each subgroup were mutually compared. INTERVENTION Percutaneous balloon valvuloplasty with mean (SD) balloon to annulus ratio of 0.93. Main outcome measures were repeat BAV, significant aortic regurgitation (AR), and aortic valve replacement/repair. RESULTS The incidence of significant AR from the whole cohort was 9.9% (8% moderate, 1.9% severe); n=16. Group A=significant AR 9.5% (7.1% moderate, 2.4% severe), Group B=significant AR 11.3% (9.4% moderate, 1.9% severe), and Group C=significant AR 9% (7.5% moderate, 1.5% severe); p value=0.99 (Group C vs Group A) and 0.92 (Group C vs Group B). Repeat BAV rate was 13.3% (n=22 out of 165 patients). Group A - n=5 (11.9%), Group B - n=10 (18.2%), and Group C - n=7 (10.3%). p Value=0.78 (C vs A) and 0.19 (C vs B). Surgery in follow-up was needed in n=4 (2.4%), none in Group A, 2 patients in Group B (3.6%), and 2 patients in group C (2.9%). Patients were followed up for a period of 14 years; Group A=up to 8 years, Group B=up to 13 years, and Group C=up to 14 years. Mean survival probability after the procedure was 8 years (Group A=6.5 years, Group B=8.1 years, and Group C=9.9 years), and p value=0.49 (A vs B), 0.23 (B vs C), and 0.4 (A vs C). CONCLUSION There is no statistical difference in the long-term outcome in the adults and adolescents as compared to the children; thus BAV remains an obvious treatment of choice with good long-term outcome.

Abstract
Valvular heart disease (VHD) is caused by either damage or defect in one of the four heart valves, aortic, mitral, tricuspid or pulmonary. Defects in these valves can be congenital or acquired. Age, gender, tobacco use, hypercholesterolemia, hypertension, and type II diabetes contribute to the risk of disease. VHD is an escalating health issue with a prevalence of 2.5% in the United States alone. Considering the likely increase of the aging population worldwide, the incidence of acquired VHD is expected to increase. Technological advances are instrumental in identifying congenital heart defects in infants, thereby adding to the growing VHD population. Almost one-third of elderly individuals have echocardiographic or radiological evidence of calcific aortic valve (CAV) sclerosis, an early and subclinical form of CAV disease (CAVD). Of individuals ages >60, ~2% suffer from disease progression to its most severe form, calcific aortic stenosis. Surgical intervention is therefore required in these patients as no effective pharmacotherapies exist. Valvular calcium load and valve biomineralization are orchestrated by the concerted action of diverse cell-dependent mechanisms. Signaling pathways important in skeletal morphogenesis are also involved in the regulation of cardiac valve morphogenesis, CAVD and the pathobiology of cardiovascular calcification. CAVD usually occurs without any obvious symptoms in early stages over a long period of time and symptoms are identified at advanced stages of the disease, leading to a high rate of mortality. Aortic valve replacement is the only primary treatment of choice. Biomarkers such as asymmetric dimethylarginine, fetuin-A, calcium phosphate product, natriuretic peptides and osteopontin have been useful in improving outcomes among various disease states. This review, highlights the current understanding of the biology of VHD, with particular reference to molecular and cellular aspects of its regulation. Current clinical questions and the development of new strategies to treat various forms of VHD medically were addressed.

Abstract
The application of balloon valvotomy as primary treatment for neonatal congenital aortic stenosis is contentious. In this debate, we discuss data comparing outcomes of a percutaneous and surgical strategy between two tertiary centers that have adopted opposite therapeutic strategies. The outcomes with surgical and balloon therapies appear comparable. These contemporaneous data validate the empiric switch to primary balloon valvotomy in the modern era.

Abstract
OBJECTIVES To evaluate long-term outcome of initial aortic valve intervention in a paediatric population with congenital aortic stenosis, and to determine risk factors associated with reintervention. PATIENTS AND METHODS From 1985 to 2009, 77 patients with congenital aortic stenosis and a mean age of 5.8±5.6 years at diagnosis were followed up in our institution for 14.8±9.1 years. RESULTS First intervention was successful with 86% of patients having a residual peak aortic gradient 1 regurgitation increased by 7%. Long-term survival after the first procedure was excellent, with 91% survival at 25 years. At a mean interval of 7.6±5.3 years, 30 patients required a reintervention (39%), mainly because of a recurrent aortic stenosis. Freedom from reintervention was 97, 89, 75, 53, and 42% at 1, 10, 15, 20, and 25 years, respectively. Predictors of reintervention were residual peak aortic gradient (p=0.0001), aortic regurgitation post-intervention >1 (p=0.02), prior balloon aortic valvuloplasty (p=0.04), and increased left ventricular posterior wall thickness (p=0.1). CONCLUSIONS Aortic valve intervention is a safe and effective procedure for congenital aortic stenosis with excellent survival results. However, rate of reintervention is high and influenced by increased left ventricular posterior wall thickness pre-intervention, prior balloon valvuloplasty, higher residual peak systolic valve gradient, and more than mild regurgitation post-intervention. The study highlights that long-term follow-up is recommended for these patients.

Abstract
Percutaneous balloon aortic valvoplasty (BAV) and surgical aortic valvotomy (SAV) are palliative procedures in patients with non-critical congenital valve stenosis. The aim of the study was to evaluate long-term BAV and SAV results after up to 24 years of follow-up. From 1987 to 2013, 74 consecutive interventions were performed in patients with aortic stenosis, and 62 were included in the study (39 BAVs and 23 SAVs). Age of BAV patients was 1.3 months to 17 years, and of SAV patients 1.2 months to 15 years. Although BAV patients were older, there was no difference between groups according to sex, valve function/morphology, and early/late follow-up results, with exception to hospitalization period. Significant pressure gradient reduction and aortic regurgitation increment were registered after procedures. Three patients did not survive early period after surgery. Follow-up period was 7.0 ± 5.4 and 9.0 ± 8.0 years after BAV and SAV, respectively (p = 0.242). Follow-up pressure gradient rose only in the BAV group, and was emphasized after 10-year-follow-up (p = 0.020). Significant aortic insufficiency progression was registered after 15 years of follow-up in both groups (p = 0.007 and p = 0.009, respectively). Mean reintervention-free survival was 12.0 years in the BAV and 14.5 years in the SAV group (p = 0.733), and mean survival without aortic valve replacement was 15.2 and 17.4 years, respectively (p = 0.877). BAV and SAV in patients with congenital aortic stenosis are very comparable in both early and late follow-up results.

Abstract
Optimization of the relationship between the supply and the demand for medical services should ideally be taken into consideration for the planning within each national Health System. Although government national health organizations embrace this policy specifically, the contribution of expert committees (under the scientific societies' guarantee in any specific medical field) should be advocated for their capability to collect and analyze the data reported by the various national institutions. In addition, these committees have the competence to analyze the need for the resources necessary to the operation of these centers. The field of pediatric cardiology and cardiac surgery may represent a model of clinical governance of particular interest with regard to programming and to a definition of the quality standards that may be extended to highly specialized institutions and ideally to the entire Health System. The "Baby Heart Project," which represents a model of governance and clinical quality in the field of pediatric cardiology and cardiac surgery, was born from the spontaneous aggregation of a committee of experts, supported by duly appointed Italian Scientific Societies and guided by a national agency for accreditation. The ultimate aim is to standardize both procedures and results for future planning within the national Health System.

Abstract
Aortic stenosis is a congenital or acquired reduction in the area of the aortic valve, resulting in obstruction of the blood flow from the left ventricle to the aorta. Aortic stenosis accounts for 2-5% of all congenital heart defects and is a potentially life-threatening disorder. In adults aortic stenosis represents 34% of all valvular heart diseases. Degenerative etiology is present in 80% of cases. Patients with mild aortic stenosis are usually asymptomatic. Symptoms of the disease occur along with the disappearance of effective compensatory mechanisms. These are symptoms of low cardiac output syndrome manifested as fainting, dizziness, ischemic pains, exercise intolerance, arrhythmias with the risk of sudden cardiac death, and heart failure. As soon as the symptoms occur the prognosis significantly worsens, which is associated with a high risk of death. Percutaneous aortic valvuloplasty is a palliative method of treatment of aortic stenosis. The aim of the procedure is to relieve left ventricular outflow tract obstruction, thereby improving cardiac output. The etiology, course of the aortic stenosis and treatment methods, including invasive procedures, vary depending on the patients' age. The purpose of this paper is to present the characteristics of the aortic valve disease and the strategy of aortic balloon valvuloplasty in different age groups.

Abstract
Neonatal aortic stenosis is a complex and heterogeneous condition, defined as left ventricular outflow tract obstruction at valvular level, presenting and often requiring treatment in the first month of life. Initial presentation may be catastrophic, necessitating hemodynamic, respiratory and metabolic resuscitation. Subsequent management is focused on maintaining systemic blood flow, either via a univentricular Norwood palliation or a biventricular route, in which the effective aortic valve area is increased by balloon dilation or surgical valvotomy. In infants with aortic annular hypoplasia but adequately sized left ventricle, the Ross-Konno procedure is also an attractive option. Outcomes after biventricular management have improved in recent years as a consequence of better patient selection, perioperative management and advances in catheter technology. Exciting new developments are likely to significantly modify the natural history of this disorder, including fetal intervention for the salvage of the hypoplastic left ventricle; 3D echocardiography providing better definition of valve morphology and aiding patient selection for a surgical or catheter-based intervention; and new transcutaneous approaches, such as duel beam echo, to perforate the valve.

Abstract
INTRODUCTION Standardization of care can reduce practice variation, optimize resource utilization, and improve clinical outcomes. We have created a standardized clinical assessment and management plan (SCAMP) for patients having balloon aortic valvuloplasty (BAV) for congenital aortic stenosis (AS). This study compares acute outcomes of BAV at our institution before and after introduction of this SCAMP. METHODS In this retrospective matched cohort study, each SCAMP patient was matched to four historical controls. Outcomes were categorized based on the combination of residual AS and aortic regurgitation (AR) as: (1) Optimal: gradient ≤ 35 mm Hg and trivial or no AR; (2) Adequate: gradient ≤ 35 mm Hg and mild AR; (3) Inadequate: gradient > 35 mm Hg and/or moderate or severe AR. RESULTS All 23 SCAMP patients achieved a residual AS gradient ≤ 35 mm Hg; the median residual AS gradient for the SCAMP group was lower (25 [10-35] mm Hg) than in matched controls (30 [0-65] mm Hg; P = 0.005). The two groups did not differ with regard to degree of AR grade after BAV. Compared with controls, SCAMP patients were more likely to have an optimal result and less likely to have an inadequate result (52% vs. 34% and 17% vs. 45%, respectively; P = 0.02) CONCLUSIONS: A SCAMP for BAV resulted in optimal acute results in half of the initial 23 patients enrolled, and outcomes in this group were better than those of matched historical controls. Whether these improved acute outcomes translate into better long-term outcomes for this patient population remains to be seen.

Abstract
BACKGROUND Transcatheter balloon aortic valvuloplasty has become the first-line treatment for critical or severe aortic stenosis in neonates in many centers. Aortic regurgitation following balloon aortic valvuloplasty remains a major concern. An optimal balloon size to aortic annulus ratio in order to minimize aortic regurgitation postprocedure, while relieving the obstruction, has not yet been identified. METHODS AND RESULTS In this retrospective study, data from 29 neonates with critical or severe congenital aortic valve stenosis, who underwent balloon aortic valvuloplasty in the first 28 days of life, over an 11-year period, was evaluated. The balloon size used, ranged from 71% to 160% of the annulus size, with an average of 89%, based on the aortic annulus size as measured on angiography. The aortic regurgitation immediately following the procedure was trivial in 8 (27.6%), mild in 13 (44.8%), moderate in 7 (24.1%), and severe in 1 (3.4%) patient. The balloon to annulus ratio had no statistically significant effect on the degree of aortic regurgitation immediately after the procedure (P-value of 0.25), at first follow-up within 6 weeks of the procedure (P-value of 0.76) or at follow-up at 1 year (P-value of 0.52). CONCLUSION This study did not show any significant relationship between the balloon to annulus ratio during interventional dilatation and the degree of aortic regurgitation following the procedure.

Abstract
BACKGROUND For children with congenital aortic stenosis (AS) who are selected for biventricular repair, valvuloplasty can be achieved by surgical aortic valvuloplasty (SAV) or by transcatheter balloon aortic dilation (BAD). A retrospective study was undertaken to compare the effectiveness of BAD versus SAV, evaluating the long-term survival, incidence of aortic valve restenosis or aortic insufficiency (AI) or both, and freedom from reoperation for repeated valve repair or replacement. Neonates less than 2 months of age were excluded from this comparison. METHODS We reviewed the outcomes of children undergoing repair by SAV (n = 89) and BAD (n = 69) at our institution during a recent 20-year period. Clinical and echocardiographic follow-up were analyzed. The patient groups were compared with regard to the persistence or recurrence of postoperative aortic gradients and valve insufficiency and valve-related reintervention, including aortic valve replacement (AVR). RESULTS There was no significant difference between the groups with respect to mean age, body surface area, valve anatomy, sex, and preoperative gradients. Our data demonstrate that gradient reduction, AI, and the need for reintervention were worse for BAD. Aortic gradients at last follow-up were similar in both cohorts, but return of a significant gradient occurred sooner for patients who had BAD. Aortic gradient at discharge was significantly better for the patients who underwent SAV. Kaplan-Meier analysis showed that at 10 years, comparison of SAV and BAD was as follows: freedom from reintervention, 72% versus 53% (p = 0.02) and freedom from AVR, 80% versus 75% (p = 0.32). CONCLUSIONS BAD yields less gradient reduction, more postprocedural AI, and a shorter interval between initial and subsequent reintervention than does SAV. Our results demonstrate that SAV is safe and effective and that residual gradients and degree of AI are low. After SAV, the need for AVR can usually be delayed until the child is significantly older. The long-term functional stability after SAV is excellent. BAD in comparison is associated with an increased frequency and severity of AI and the need for earlier reintervention and valve replacement. SAV should be offered to all patients beyond the newborn period because it gives superior and longer lasting palliation.

Abstract
Background: Balloon valvuloplasty was established as an alternative to surgery for treatment of aortic valve stenosis in childhood. Acute complications after balloon dilatation including aortic insufficiency or early death were described. Aim of Work: To analyze early outcome and midterm results of balloon aortic valvuloplasty (BAV) in Children’s Hospital, Mansoura University, Egypt. Subjects and Methods: Between April 2005–June 2008, all consecutive patients of age <18 years treated for aortic valve stenosis (AVS) with BAV were analyzed retrospectively. The study included 21 patients; 17 males, and 4 females. Their age ranged from the neonatal period to 10 years (mean age 5.6 ± 3.7 years). Patients with gradient ≥50 mmHg and aortic valve insufficiency (AI) up to grade I were included. All patients had isolated aortic valve stenosis except 3 patients (14.3%) had associated aortic coarctation. Six patients (28.6%) had bicuspid aortic valve. All patients had normal myocardial function except one (4.8%) had FS 15%. The duration of follow up was (mean ± SD: 18.5 ± 11.7 months). Results: Femoral artery approach was used in 20 patients (95.2%) and carotid artery in one neonate (4.8%). Balloon/annulus ratio was 0.83 ± 0.04. Significant reduction in pressure gradient was achieved (mean 66.7 ± 9.8 mmHg to 20.65 ± 2.99 mmHg) (P < 0.001). Nine patients (42.8%) developed grade I AI, 2 patients (9.5%) developed grade II AI and 1 patient (4.8%) developed grade III AI. Two early deaths (9.5%); one died due to heart failure caused by grade IV AI and a neonate died because of severely compromised LV function. One patient (4.8%) had femoral artery occlusion necessitating anticoagulation. Patients remained free from re-intervention during follow up. Conclusion: Balloon valvuloplasty of aortic valve stenosis significantly reduces gradient with low morbidity and mortality in children.

Abstract
In all cases of congenital valvar aortic stenosis (AS), reduced effective orifice area leads to obstruction to flow, usually resulting from thickening and reduced motion of the valve leaflets. The most severe cases of valvar AS present soon after birth, with low cardiac output secondary to left ventricular dysfunction. Interventional treatment options consist of open surgical valvotomy or balloon valvuloplasty, with both therapies providing excellent but usually only temporary relief of stenosis. This article focuses on balloon aortic valvuloplasty as a therapy for congenital valvar AS in infants and children, focusing on established techniques, outcomes, and future challenges.

Abstract
CONTEXT Calcific Aortic Valve Disease (CAVD) is an active pathological process leading to biomineralization of the aortic cusps. We characterized circulating and tissue Osteopontin (OPN) as a biomarker for CAVD. OBJECTIVES Here we investigate the post-translational modifications of circulating OPN and correlate the phosphorylation status with the ability to prevent calcification. METHODS Circulating OPN levels were estimated in CAVD patients (n = 51) and controls (n = 56). In a subgroup of 27 subjects, OPN was purified and the phosphorylation status analyzed. RESULTS Plasma OPN levels were significantly elevated in CAVD patients as compared to the controls and correlates with the aortic valve calcium score. Our study demonstrates that phospho-threonine levels of OPN purified from controls were higher when compared to CAVD subjects, whereas phospho-serine and phospho-tyrosine levels were comparable between the two groups. CONCLUSION The dephosphorylation of circulating OPN correlates with severe valvular calcification in patients with CAVD.

Abstract
BACKGROUND Calcific aortic valve disease (CAVD) is the most common cause of acquired valve disease. Initial phases of CAVD include thickening of the cusps, whereas advanced stages are associated with biomineralization and reduction of the aortic valve area. These conditions are known as aortic valve sclerosis (AVSc) and aortic valve stenosis (AVS), respectively. Because of its asymptomatic presentation, little is known about the molecular determinants of AVSc. The aim of this study was to correlate plasma and tissue osteopontin (OPN) levels with echocardiographic evaluation for the identification of asymptomatic patients at risk for CAVD. In addition, our aim was to analyze the differential expression and biological function of OPN splicing variants as biomarkers of early and late stages of CAVD. METHODS From January 2010 to February 2011, 310 patients were enrolled in the study. Patients were divided into 3 groups based on transesophageal echocardiographic (TEE) evaluation: controls (56 patients), AVSc (90 patients), and AVS (164 patients). Plasma and tissue OPN levels were measured by immunohistochemical evaluation, enzyme-linked immunosorbent assay (ELISA), and real-time quantitative polymerase chain reaction (qPCR). RESULTS Patients with AVSc and AVS have higher OPN levels compared with controls. OPN levels are elevated in asymptomatic patients with AVSc with no appearance of calcification during TEE evaluation. OPN splicing variants OPN-a, OPN-b, and OPN-c are differentially expressed during CAVD progression and are able to inhibit biomineralization in a cell-based biomineralization assay. CONCLUSIONS The analysis of the differential expression of OPN splicing variants during CAVD may help in developing diagnostic and risk stratification tools to follow the progression of asymptomatic aortic valve degeneration.

Abstract
Calcific aortic stenosis (CAS) is a pathological condition of the aortic valve characterized by dystrophic calcification of the valve leaflets. Despite the high prevalence and mortality associated with CAS, little is known about its pathogenetic mechanisms. Characterized by progressive dystrophic calcification of the valve leaflets, the early stages of aortic valve degeneration are similar to the active inflammatory process of atherosclerosis including endothelial disruption, inflammatory cell infiltration, lipid deposition, neo-vascularization and calcification. In the vascular system, the endothelium is an important regulator of physiological and pathological conditions; however, the contribution of endothelial dysfunction to valvular degeneration at the cellular and molecular level has received little attention. Endothelial cell (EC) activation and neo-vascularization of the cusps characterizes all stages of aortic valvular degeneration from aortic sclerosis to aortic stenosis. Here we reported the role of osteopontin (OPN) in the regulation of EC activation in vitro and in excised tissue from CAS patients and controls. OPN is an important pro-angiogenic factor in several pathologies. High levels of OPN have been demonstrated in both tissue and plasma of patients with aortic valve sclerosis and stenosis. The characterization of valvular ECs as a cellular target for OPN will help us uncover the pathogenesis of aortic valve degeneration and stenosis, opening new perspectives for the prevention and therapy of this prevalent disease.

Abstract
OBJECTIVES The aim of this article is to report a 16-year experience with percutaneous balloon aortic valvuloplasty (BAVP) in newborns and young infants up to 3 months of age in a tertiary care cardiac reference center in a developing country and to determine its value in postponing open heart surgery. BACKGROUND Congenital aortic stenosis (AS) is a potentially life threatening disorder. BAVP and surgical procedures have similar short and medium-term efficacy. METHODS Thirty-one consecutive newborns and young infants with critical AS underwent BAVP in our department from 1991 to 2007. Mean patient age at time of the procedure was 22 days (range 2-92 days) and mean weight was 3,310 g (1,840-4,400 g). RESULTS There was a significant reduction in mean Doppler-derived peak gradient across the aortic valve immediately after the procedure (75.1 ± 22 versus 32.2 ± 13.02, P < 0.001), and this finding was maintained throughout follow-up. Since 2003, when the carotid approach became routine practice, no major vascular complications were observed. Mean time of follow-up was 81 months (5 days-196 months) with only two deaths (7.4%). Only 24% patients required surgical reintervention on the aortic valve during follow-up. Survival free from aortic valve surgery was 80% at 24 months, 66% at 63 months, and 50% at 80 months. CONCLUSION Percutaneous intervention for relief of critical aortic stenosis in newborns in a tertiary center of a developing country is safe and has excellent short and long-term results comparable to other centers throughout the world.

Abstract
OBJECTIVES the aim of this study was to evaluate the long-term results of transcatheter balloon aortic valvuloplasty, the preferred treatment for congenital aortic stenosis (AS). BACKGROUND aortic valve function and reintervention late after this procedure are not well characterized. METHODS from 1985 to 2008, 563 patients underwent balloon dilation for congenital AS. After excluding those converted to univentricular circulation and/or died ≤ 30 days after the procedure, 509 patients constituted the study cohort. RESULTS The median follow-up period was 9.3 years (range 0.1 to 23.6 years); cumulative follow-up was 5,003 patient-years. The median age was 2.4 years (range 1 day to 40.5 years), and most patients (73%) had isolated native AS. Peak AS gradients decreased significantly after dilation (median decrease, 35 mm Hg), and acute post-dilation aortic regurgitation was moderate or greater in 70 patients (14%). Older patients more often had post-dilation aortic regurgitation (p < 0.001). During follow-up, 225 patients (44%) underwent aortic valve reintervention: repeat balloon dilation in 115 (23%), aortic valve repair in 65 (13%), and aortic valve replacement in 116 (23%). Survival free from any aortic valve reintervention was 89 ± 1% at 1 year, 72 ± 2% at 5 years, 54 ± 3% at 10 years, and 27 ± 3% at 20 years. Freedom from aortic valve replacement was 90 ± 2% at 5 years, 79 ± 3% at 10 years, and 53 ± 4% at 20 years. In multivariate analyses, lower post-dilation AS gradient and lower grade of post-dilation aortic regurgitation were associated with longer freedom from aortic valve replacement, but age, era, and pre-dilation AS severity were not. CONCLUSIONS although transcatheter aortic valvuloplasty is effective for relief of congenital AS, there are steady long-term hazards for surgical aortic valve reintervention and replacement that are independent of age at initial intervention or AS severity.

Abstract
Calcific aortic valve disease (CAVD) is the most common acquired valvular disorder in developed countries. CAVD ranges from mild thickening of the valve, known as aortic valve sclerosis (AVSc), to severe impairment of the valve motion, which is termed aortic valve stenosis (AVS). The prevalence of CAVD is nearing epidemic status: its preceding stage, in which there is aortic sclerosis without obstruction of the left ventricular outflow, is present in almost 30% of adults aged over 65 years. As there is no existing medical therapy to treat or slow the progression of CAVD, surgery for advanced disease represents the only available treatment. Aortic valve replacement is the second most frequently performed cardiac surgical procedure after coronary artery bypass grafting, and consequently CAVD represents a major societal and economic burden. The pathophysiological development of CAVD is incompletely defined. At the present time, the major methods for its diagnosis are clinical examination, echocardiography, and cardiac catheterization. Yet, due to the multiple biological pathways leading to CAVD, there are many potential biomarkers that might be suitable for deriving clinically useful information regarding the presence, severity, progression, and prognosis of CAVD. Although at the present time the available data do not permit recommendations for clinicians, they do support a paradigm of screening patients based on multiple biomarkers to provide the information necessary to optimize future therapeutic interventions. This review summarizes the results of several studies investigating the value of potential biomarkers that have been used to predict the severity, progression, and prognosis of CAVD.

Abstract
BACKGROUND Calcific aortic stenosis (CAS) is the most common acquired valvular disorder in industrialized countries. This study investigates the correlation of different known biomarkers for CAS as a first step towards the development of a panel of biomarkers that can be used in prognostic staging. METHODS Venous blood samples were obtained from both patients with CAS scheduled for surgery and healthy individuals. Plasma levels of fetuin-A, NT-proBNP, BNP, homocysteine and osteopontin were measured by enzyme-linked immunosorbent assay (ELISA). CAS was measured by echocardiography and was defined as an aortic valve area of less than 2.0 cm(2). Non-paired t-tests were used for comparison. RESULTS CAS was present in 33 subjects (mean age 75.9 y) and absent in 11 subjects (mean age 55.36 y). Individuals with CAS exhibited higher plasma levels of NT-proBNP (1.33 versus 0.73 pmol/mL, P < 0.05), BNP fragment (1.47 versus 0.34 ng/mL P < 0.05), and osteopontin (60.79 versus 25.42 ng/mL P < 0.05) compared with controls. Fetuin-A levels were lower in individuals with CAS than in healthy controls (0.25 versus 0.34g/L, P < 0.05). Asymmetric dimethylarginine (ADMA) were lower (1.08 versus 1.1 micromol/L, P > 0.05) while homocysteine levels (20.34 +/- 2.14 versus 19.23 +/- 4.19 P > 0.05) were higher in the CAS patients. CONCLUSION This study demonstrates a direct correlation of NT-pro-BNP, BNP, and osteopontin and the presence of CAS, while fetuin A showed an inverse correlation. Plasma ADMA and homocysteine levels were comparable in the CAS patients and healthy individuals. This is the first study in which several biomarkers previously studied independently in patients with CAS have been investigated simultaneously in the same study population.

Abstract
BACKGROUND The value of balloon valvuloplasty of the aortic valve in childhood is still under debate. OBJECTIVE To evaluate the results of the procedure in a retrospective multicenter survey of a large cohort over a long time interval. METHODS Retrospective analysis of 1004 patients with balloon valvuloplasty of the aortic valve performed between 9/1985 and 10/2006 at 20 centers in Germany, Austria and Switzerland. Amongst others, the following parameters were evaluated before and after the procedure as well as at the end of follow-up or before surgery: clinical status, left ventricular function, transaortic pressure gradient, degree of aortic regurgitation, freedom from re-intervention or surgery. PATIENTS Patients from 1 day to 18 years of age with aortic valve stenosis were divided into four groups: 334 newborns (1-28 days); 249 infants (29-365 days); 211 children (1-10 years), and 210 adolescents (10-18 years). RESULTS Median follow-up was 32 months (0 days to 17.5 years). After dilatation the pressure gradient decreased from 65 (± 24)mm Hg to 26 (± 16)mm Hg and remained stable during follow-up. The newborns were the most affected patients. Approximately 60% of them had clinical symptoms and impaired left ventricular function before intervention. Complication rate was 15% in newborns, 11% in infants and 6% in older children. Independently of age, 50% of all patients were free from surgery 10 years after intervention. CONCLUSIONS In this retrospective multicenter study, balloon valvuloplasty of the aortic valve has effectively postponed the need for surgery in infants, children and adolescents up to 18 years of age.

Abstract
BACKGROUND We report the experience in a single institution with balloon aortic valvoplasty for congenital aortic stenosis. Unlike most other reported series, we included patients with associated lesions involving the left side of the heart. METHODS Between November, 1986, and November, 2006, we performed 161 interventions on 143 patients, of whom 33 were neonates, 33 infants, and 77 children, just over one-quarter (28.6%) having associated lesions. RESULTS The overall reduction in peak-to-peak gradient of 60 ± 24% (p < 0.01), was more effective in primary versus secondary intervention (63 ± 24% versus 47 ± 23%; p < 0.03), and in those with fused bifoliate as opposed to truly bifoliate valves (66 ± 17% versus 53 ± 30%; p = 0.01). Patients with associated lesions were younger (40.89 ± 60.92 months versus 81.9 ± 72.9 months; p = 0.001), and were less likely to achieve a final pressure gradient of less than 20 mmHg (35.0% versus 61.2%; p < 0.01). Overall mortality was higher in cases with associated lesions (27.5% versus 1.9%; p < 0.0001) but not catheter-related death (2.5% versus 1.9%; p = 1.0). Reintervention was more frequently required in infants (p = 0.02) but not in cases with associated lesions (p = 0.35). CONCLUSIONS Balloon valvoplasty is a safe and effective method for the treatment of congenital aortic stenosis. Prior surgery to the aortic valve, reintervention, associated cardiovascular lesions, and the anatomy of the valve predict a less effective reduction in the gradient. Major complications and catheterization-related death are mainly secondary to very young age, but not to associated cardiac lesions.

Abstract
Most children with aortic valve disease present with isolated aortic regurgitation or stenosis, in which case valve repair is often possible, thus delaying or eliminating the need for valve replacement. In the child with mixed aortic stenosis and regurgitation, repair is often more complex and less successful, requiring replacement of the valve and/or root. Several elements require careful consideration in children including growth potential of the child, risk of future reoperations, and the need for anticoagulation. A formal decision tree in this context is difficult because of the high variability between patients and pathologies and the lack of prospective randomized data. Nevertheless, we here present our approach to the child with mixed aortic stenosis and regurgitation, exploring the various options and explaining our favored approach.

Abstract
INTRODUCTION Few data exist regarding the potential benefits of continuous echocardiographic guidance during balloon aortic valvuloplasty (BAV) for the treatment of congenital aortic stenosis (AS). The objectives of this study were 1) to prospectively evaluate, in a series of consecutive patients with severe AS, the efficacy of BAV guided by Doppler echocardiography (DE) in relieving AS while preventing the appearance of significant aortic regurgitation (AR), and 2) to compare the results obtained by BAV-DE with those obtained in a historical series of patients who underwent BAV without echocardiographic guidance (BAV guided by angiography, BAV-A). METHODS From 1995 to 2006 a total of 36 consecutive patients with AS (median age 6 years, range, 1 day to 26 years) underwent BAV in our center, with systematic application of continuous DE guidance since 2003. BAV-DE consisted of measuring the aortic annulus, choosing balloon diameters and evaluating the results of each balloon dilation on the basis of DE. RESULTS Seventeen patients underwent BAV-DE (transthoracic and transesophageal DE in 3 and 14 patients, respectively) with successful transaortic gradient relief in 88% of them. None of the patients complicated with moderate or severe AR. At 17+/-13 months follow-up there had been 3 cardiac events (18%), all of them related to aortic restenosis. BAV-A was associated with longer fluoroscopic times (35 min vs 16 min, p=0.005 after adjusting for age and weight differences between groups) and a higher degree of AR following BAV (>or=2 degrees increase in AR, 32% vs 0%, p=0.045 after adjusting for age and weight). Angiographic measurements of the aortic annulus were higher than those obtained by DE (mean overestimation+2.5+/-1.8 mm, range 0 to +6 mm, p<0.0001). CONCLUSION BAV-DE provides successful gradient relief of severe AS with lower fluoroscopy time and a lower degree of AR compared to BAV-A. Overestimation of aortic annulus diameters by angiographic measurements might partially explain the high rate of significant AR associated with BAV in the absence of echocardiographic guidance.

Abstract
Background—
Aortic valvuloplasty (AoVP) is an established procedure regarded as a valid alternative for surgical management of congenital aortic valve stenosis. However, its long-term efficacy in preventing or postponing aortic valve surgery remains uncertain for the individual patient. Therefore, the aim of this study was to study the long-term results of AoVP in pediatric patients and its efficacy in preventing or postponing aortic valve surgery.
Methods and Results—
We reviewed up to 17.5 years of follow-up data of all 188 patients who received AoVP at the Deutsches Herzzentrum München. The patients were divided into those <1 month of age (group <1 month; n=68) and those ≥1 month of age (group ≥1 month; n=120) at the time of AoVP. After the first and second AoVP, moderate and severe aortic regurgitation developed in 29% and 14%, respectively, of the patients in group <1 month and in 19% and 29%, respectively, of the patients in group ≥1 month. Survival after 10 years free from aortic valve surgery was 59% (95% confidence interval, 45 to 73) in group <1 month and 70% (95% confidence interval, 59 to 81) in group ≥1 month.
Conclusions—
This study shows that the long-term results of AoVP of congenital aortic valve stenosis in pediatric patients and its efficacy in preventing or postponing aortic valve surgery are very good. About two thirds of the patients are free from aortic valve surgery 10 years after AoVP.
