Outcomes post Ozaki procedure among children with aortic valve disease at Jakaya Kikwete Cardiac Institute, Dar es Salaam, Tanzania: a retrospective descriptive study. BMC Cardiovasc Disord 2024; 24:163. [PMID: 38504187 PMCID: PMC10949633 DOI: 10.1186/s12872-024-03829-8] [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: 06/02/2023] [Accepted: 03/04/2024] [Indexed: 03/21/2024] Open
Abstract
BACKGROUND Aortic valve reconstruction using glutaraldehyde-treated autologous pericardium, also called Ozaki procedure, is a surgical procedure for patients with aortic valve disease. Gratifying results have been reported in adult patients, however, limited published data is available in paediatric population. This study looked at clinical characteristics and early outcomes of children who underwent Ozaki procedure at our Institute. METHODS This was a retrospective descriptive study conducted on children who underwent aortic valve reconstruction at Jakaya Kikwete Cardiac Institute (JKCI) from January 2019 through December 2022. Medical records of these children were reviewed to extract data on demographics, clinical characteristics, redo surgical interventions and survival. RESULTS A total of 10 children underwent Ozaki procedure during the study period. Eight children had severe aortic regurgitation while 2 had severe aortic stenosis preoperatively. All children had either none or trivial aortic regurgitation immediately after surgery. None of them had redone operations throughout the follow-up period. There was no in-hospital mortality, however, one child died one-year after surgery. The mean follow-up period was 1.6 years with the longest follow-up time of 4 years. CONCLUSION Ozaki procedure showed encouraging early results among children with aortic valve disease who underwent surgical repair by this technique. Future studies with larger sample sizes and longer follow up periods to evaluate long-term results in this population are recommended.

Abstract
Aortic stenosis (AS) is a common form of left ventricular outflow tract obstruction (LVOTO) in children with congenital heart disease. This review specifically considers the perioperative features of valvar (VAS) and subvalvar AS (subAS) in the pediatric patient. Although VAS and subAS share some clinical features and diagnostic approaches, they are distinct clinical entities with separate therapeutic options, which range from transcatheter intervention to surgical repair. We detail the pathophysiology of AS and highlight the range of treatment strategies with a focus on anesthetic considerations for the care of these patients before, during, and after intervention.

Aortic valve repair in neonates, infants and children: a systematic review, meta-analysis and microsimulation study. Eur J Cardiothorac Surg 2023; 64:ezad284. [PMID: 37584683 PMCID: PMC10502195 DOI: 10.1093/ejcts/ezad284] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/21/2023] [Revised: 07/24/2023] [Accepted: 08/14/2023] [Indexed: 08/17/2023] Open
Abstract
OBJECTIVES To support clinical decision-making in children with aortic valve disease, by compiling the available evidence on outcome after paediatric aortic valve repair (AVr). METHODS A systematic review of literature reporting clinical outcome after paediatric AVr (mean age at surgery <18 years) published between 1 January 1990 and 23 December 2021 was conducted. Early event risks, late event rates and time-to-event data were pooled. A microsimulation model was employed to simulate the lives of individual children, infants and neonates following AVr. RESULTS Forty-one publications were included, encompassing 2 623 patients with 17 217 patient-years of follow-up (median follow-up: 7.3 years; range: 1.0-14.4 years). Pooled mean age during repair for aortic stenosis in children (<18 years), infants (<1 year) or neonates (<30 days) was 5.2 ± 3.9 years, 35 ± 137 days and 11 ± 6 days, respectively. Pooled early mortality after stenosis repair in children, infants and neonates, respectively, was 3.5% (95% confidence interval: 1.9-6.5%), 7.4% (4.2-13.0%) and 10.7% (6.8-16.9%). Pooled late reintervention rate after stenosis repair in children, infants and neonates, respectively, was 3.31%/year (1.66-6.63%/year), 6.84%/year (3.95-11.83%/year) and 6.32%/year (3.04-13.15%/year); endocarditis 0.07%/year (0.03-0.21%/year), 0.23%/year (0.07-0.71%/year) and 0.49%/year (0.18-1.29%/year); and valve thrombosis 0.05%/year (0.01-0.26%/year), 0.15%/year (0.04-0.53%/year) and 0.19%/year (0.05-0.77%/year). Microsimulation-based mean life expectancy in the first 20 years for children, infants and neonates with aortic stenosis, respectively, was 18.4 years (95% credible interval: 18.1-18.7 years; relative survival compared to the matched general population: 92.2%), 16.8 years (16.5-17.0 years; relative survival: 84.2%) and 15.9 years (14.8-17.0 years; relative survival: 80.1%). Microsimulation-based 20-year risk of reintervention in children, infants and neonates, respectively, was 75.2% (72.9-77.2%), 53.8% (51.9-55.7%) and 50.8% (47.0-57.6%). CONCLUSIONS Long-term outcomes after paediatric AVr for stenosis are satisfactory and dependent on age at surgery. Despite a high hazard of reintervention for valve dysfunction and slightly impaired survival relative to the general population, AVr is associated with low valve-related event occurrences and should be considered in children with aortic valve disease.

Abstract
Management of aortic valve diseases in children is challenging owing to the quality and quantity of the native tissue for repair, limitations in the currently available biological materials to supplement the repair and to achieve a long-lasting durable repair in an annulus where there is still growth potential. The aortic valve neocuspidization (AVNeo) procedure has emerged as a versatile alternative strategy in the armamentarium of pediatric aortic valve reconstructions that are currently available. In this review article, the focus of the discussion will be on the various aortic valve repair procedures in the pediatric population, with a special emphasis on the emerging role of AVNeo procedure in pediatrics and its outcomes.

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.

Ann Thorac Surg 2023; 115:159-165. [PMID: 36075398 DOI: 10.1016/j.athoracsur.2022.08.032] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/01/2022] [Revised: 07/27/2022] [Accepted: 08/08/2022] [Indexed: 12/31/2022]
Abstract
BACKGROUND We sought to validate the technical performance score (TPS) as a predictor of midterm outcomes after congenital aortic valve repair. METHODS This was a single-center, retrospective review of consecutive patients who underwent aortic valve repair between January 1, 2011, and December 31, 2019. Predischarge echocardiograms were used to assign a TPS for each index operation as class 1, no aortic valve residua; class 2, minor aortic valve residua; or class 3, major aortic valve residua or predischarge reintervention for major residua. The primary outcome was postdischarge (late) unplanned aortic valve reintervention. Secondary outcomes included late mortality and at least moderate aortic regurgitation or stenosis at the latest follow-up or before the earliest reintervention. Associations between TPS and outcomes were assessed using competing risk, Cox proportional hazards, or logistic regression models, adjusting for preoperative patient- and procedure-related covariates. RESULTS Of 507 patients, there were 110 (21.7%) reinterventions, 22 (4.3%) deaths, and 67 (13.2%) cases of at least moderate aortic regurgitation or stenosis at the latest follow-up or earliest reintervention. On multivariable analysis, class 3 patients had a greater risk of reintervention (subdistribution hazard ratio, 2.6; 95% CI, 1.3-5.1; P = .005) and mortality (hazard ratio, 5.3; 95% CI. 1.1-25.2; P = .038) compared with class 1 patients. Adjusting for duration of follow-up, class 3 patients also had a greater risk of at least moderate aortic regurgitation or stenosis at the latest follow-up or earliest reintervention (odds ratio, 7.7; 95% CI, 2.5-24.2; P < .001) vs class 1 patients. CONCLUSIONS Patients with major residua after congenital aortic valve repair have significantly worse midterm outcomes compared with those with no residua, warranting closer follow-up.

Abstract
The ideal aortic valve substitute in young adults remains unknown. Prosthetic valves are associated with a suboptimal survival and carry a significant risk of valve-related complications in young patients, mainly reinterventions with tissue valves and, thromboembolic events and major bleeding with mechanical prostheses. The Ross procedure is the only substitute that restores a survival curve similar to that of a matched general population, and permits a normal life without functional limitations. Though the risk of reintervention is the Achilles' heel of this procedure, it is very low in patients with aortic stenosis and can be mitigated in patients with aortic regurgitation by tailored surgical techniques. Finally, the Ozaki procedure and the transcatheter aortic valve implantation are seen by many as future alternatives but lack evidence and long-term follow-up in this specific patient population.

Abstract
The surgical treatment for young patients with aortic valve diseases has not been standardized because of differences in the patients' growth. We aimed to investigate short-term results of aortic valve repair with leaflet extension techniques. From October 2017 to June 2020, we performed aortic valve repair with leaflet extension technique in 15 consecutive patients with a median age of 13 years (range, 33 months-27 years). Among them, all had moderate or severe aortic regurgitation (AR), eight had concomitant aortic stenosis, and 12 underwent prior cardiac operations. The leaflet patch design has been modified from separate patch design to single patch design. No early and late deaths were reported, no re-operations were performed, and temporary ectopic atrial arrhythmia was the only early complication noted. The patients were discharged with less than moderate AR after a median postoperative period of 5 (range, 3-7) days. All the patients were New York Heart Association class I after a median follow-up period of 17.3 (range, 4.4-34.6) months. However, two patients progressed to moderate AR postoperatively at 6 and 30 months, respectively, after which one was treated with single patch technique. Among the remaining patients, six had trace, six had mild, and one had mild-to-moderate AR. Aortic valve repair with leaflet extension is acceptable in young patients. Our single patch design was easy to manipulate and showed good short-term results. Long-term follow-up is required to further confirm the efficacy of this technique.

Abstract
BACKGROUND Aortic valve neo-cuspidization (AVNeo), a procedure wherein the aortic valve is reconstructed utilizing an autologous pericardium, has recently been more commonly performed in children. However, the postoperative morphological changes in the aortic valve of pediatric patients remain unknown. The current study aimed to describe the intraoperative and postoperative findings of aortic regurgitation (AR) and stenosis (AS) after AVNeo in children. METHODS This case series describes the morphological changes in AR and AS, and their severity, between the perioperative period and 3 months postoperative period after AVNeo in children (<18 years) who underwent AVNeo between April 2016 and March 2020. Data were collected at two measurement points: (i) intraoperative transesophageal echocardiography after weaning from cardiopulmonary bypass (io-TEE); (ii) postoperative transthoracic echocardiography 3 months after the procedure (po-TTE). RESULTS Seven patients were included in this case series. The number of postoperative AR sites and the ratio of AR jet area to the left ventricular outflow tract area showed a tendency to decrease between io-TEE and po-TTE. All AR sites were integrated during the postoperative period. One patient identified developed intraoperative AS, which maintained its severity after AVNeo. CONCLUSIONS Most cases exhibited spontaneous improvement in AR, while one developed postoperative AS. Further prospective investigation is, therefore, needed to explore surgical outcomes following AVNeo among children.

Abstract
Evaluate outcomes of single leaflet aortic valve reconstruction using Ozaki sizer and template. Single institute retrospective analysis between August 2015 and August 2019. Thirty-three patients, median age 9.3 years and weight 29.2 kg underwent single leaflet Ozaki repair. Preoperative indications were: AR (n = 17), AS (n = 3) or AS/AR (n = 13). Baseline anatomy was unicuspid (n = 15), bicuspid (n = 9) or tricuspid (n = 9). Two patients had endocarditis. Prior interventions included balloon valvuloplasty (n = 22) and aortic valve repair (n = 9). Pre-op average native annulus diameter was 19.6 mm and peak echo gradient was 36 mm Hg. Autologous pericardium, Photofix and CardioCel bovine pericardium were used in 26, 5, and 2 patients. Non-coronary sinus enlargement was required in 3 and aortic root reduction in 9 patients. Single leaflet reconstruction was done for the right coronary cusp (n = 25), non-coronary cusp in (n = 6) and left coronary cusp (n = 2). Additional procedures were done in 30 patients. Median ICU and hospital LOS were 2.1 and 6.3 days. There were no early re-interventions or conversions to valve replacement and one unrelated mortality.en At discharge, all patients had < moderate AR and/or AS with average peak gradients of 15 mm Hg. The median follow-up was 1.1 year, (IQR 0.7-1.8 years). Freedom from ≥ moderate AR and AS at 2 years was 76% and 86%. One patient required surgical re-intervention for severe AR 1.5 years after surgery for inflammatory infiltrate with calcification and fibrosis. Single-leaflet aortic valve leaflet reconstruction utilizing the Ozaki technique has promising early results and can be considered in patients when there are acceptable native leaflets.

Interact Cardiovasc Thorac Surg 2021; 32:111-117. [PMID: 33221849 DOI: 10.1093/icvts/ivaa237] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/14/2020] [Revised: 08/21/2020] [Accepted: 09/16/2020] [Indexed: 12/17/2022] Open
Abstract
OBJECTIVES There is growing interest in the aortic valve (AV) neocuspidalization technique for the treatment of aortic valve disease (AVD). We report our medium-term results with this procedure performed in a paediatric patient population. METHODS Between July 2016 and May 2020, 22 patients with both congenital and acquired isolated AVD were treated with neocuspidalization. The primary outcome was progression of the preoperatively assessed AVD in the immediate postoperative course and at follow-up. Secondary outcome was freedom from reintervention by material used. Potential predictors of failure were analysed in relation to the primary outcome. RESULTS The median age at operation was 13.9 (interquartile range, 9.8-16.2) years, and the prevailing AV defect was stenosis in 10 cases (45%) and incompetence in 12 (55%). Pre-treated autologous pericardium was used in 13 patients whereas bovine pericardium in 9. Effective treatment of AV stenosis or regurgitation was achieved and remained stable over a median follow-up of 11.3 (4.7-21) months. Three patients required AV replacement at 4.9, 3.5 and 33 months. At follow-up, an upward trend of both median indexed vena contracta jet widths and aortic peak and mean gradients were recorded, the latter associated with a failure to grow the aortic annulus. Predictor of such outcome turned out to be the use of bovine pericardium. A significant inverse linear correlation between AV peak gradient at follow-up and preoperative aortic annular size (P = 0.008) was also demonstrated. CONCLUSIONS The Ozaki procedure is safe and effective in paediatric patients with AV disease. The use of heterologous pericardium should probably be minimized. Moreover, preoperative small aortic annuli should probably be promptly treated by means of an associated ring enlargement procedure.

Abstract
BACKGROUND We aimed to assess the long-term outcomes of children in whom the aortic valve could be repaired without the use of patch material. We hypothesized that if the aortic valve is of sufficiently good quality to perform repair without patches, a durable repair could be achieved. METHODS All children (n = 102) who underwent aortic valve repair without the use of a patch between 1980 and 2016 were reviewed. RESULTS The median patient age at operation was 2 years (interquartile range, 1 month to 9.6 years). There were 25 neonates and 17 infants. There was no operative mortality. Mean overall survival at 10 years was 97.7% ± 0.01% (95% confidence interval, [CI] 91.0%-99.4%). Forty-three patients (42.2%) required 56 aortic valve reoperations, including 24 redo aortic valve repairs, 22 Ross procedures, 8 mechanical aortic valve replacements, and 2 homograft aortic valve replacements. Mean freedom from aortic valve reoperation at 10 years was 57.4% ± 0.06% (95% CI, 44.9%-68.1%), and freedom from aortic valve replacement at 10 years was 74.5% ± 0.05% (95% CI, 63.0%-82.9%) at 10 years. Freedom from aortic valve reoperation at 10 years was 33.1% ± 0.1% (95% CI, 14.5%-53.2%) in neonates and 68.9% ± 0.06% (95% CI, 54.5%-79.6%) in older children (P < .01). CONCLUSIONS In approximately one-third of children undergoing aortic valve repair, the repair could be achieved without patches. In these children, aortic valve repair was achieved without operative mortality. Infants and older children have low reoperation rates, whereas reoperation rates in neonates are higher. Initial repair allows valve replacement to be delayed to later in childhood, when a more durable result may be achieved.

Abstract
BACKGROUND Aortic valve neocuspidization (AVNeo) (Ozaki procedure) has excellent midterm results in adults. Outcomes in patients with a small native aortic annulus are unknown. We report early outcomes in young patients with small native aortic valve annuli. METHODS Retrospective data of patients undergoing AVNeo between 2015 and 2019 were reviewed. Patients with native aortic annulus less than 21 mm undergoing 3-leaflet AVNeo were included. RESULTS A total of 51 patients were identified (median age 7.9 years; median weight 21 kg), and 80% patients were less than or equal to 12 years age. Preoperative indication was aortic regurgitation (AR) (n = 23), aortic stenosis (AS) (n = 22), or mixed AS and AR (n = 6). Baseline anatomy was quadricuspid (n = 1), tricuspid (n = 23), bicuspid (n = 15), or unicuspid (n = 12) valve. Preoperative peak gradient for AS and mixed AS and AR patients was 55.36 mm Hg. Median native annulus diameter was 17 mm; sinus and annular enlargements were required in 22 patients and 9 patients, respectively. Median intensive care unit and hospital length of stay were 2.0 days and 7.2 days, respectively. There were no reinterventions, and there was 1 hospital mortality unrelated to aortic valve. At discharge, 94% of patients had less than or equal to mild AR, and the median peak gradient was 18 mm Hg. At mean follow-up of 11.9 months, 80% and 82% of patients had less than moderate AR and AS, respectively. Three patients required surgical reintervention. In annular enlargement patients, mean annulus Z score remained greater than 0 at follow-up. CONCLUSIONS The Ozaki procedure has acceptable short-term results in young patients with small aortic annuli. A larger aortic annulus can be achieved with surgical annular enlargement. Long-term follow-up is necessary to determine late valve function and potential continued annular growth.

Abstract
OBJECTIVES Aortic valve reconstruction (AVRec) with neocuspidization or the Ozaki procedure with complete cusp replacement for aortic valve disease has excellent mid-term results in adults. Limited results of AVRec in pediatric patients have been reported. We report our early outcomes of the Ozaki procedure for congenital aortic and truncal valve disease. METHODS A retrospective analysis was performed on all 57 patients with congenital aortic and truncal valve disease who had a 3-leaflet Ozaki procedure at a single institution from August 2015 to February 2019. Outcome measures included mortality, surgical or catheter-based reinterventions, and echocardiographic measurements. RESULTS Twenty-four patients had aortic regurgitation (AR), 6 had aortic stenosis (AS), and 27 patients had AS/AR. Two patients had quadricuspid valves, 26 had tricuspid, 20 had bicuspid, and 9 had unicusp aortic valves. Four patients had truncus arteriosus. Thirty-four patients had previous aortic valve repairs and 5 had replacements. Preoperative echocardiography mean annular diameter was 20.90 ± 4.98 cm and peak gradient for patients with AS/AR was 53.62 ± 22.20 mm Hg. Autologous, Photofix, and CardioCel bovine pericardia were used in 20, 35, and 2 patients. Eight patients required aortic root enlargement and 20 had sinus enlargement. Fifty-one patients had concomitant procedures. Median intensive care unit and hospital length of stay were 1.87 and 6.38 days. There were no hospital mortalities or early conversions to valve replacement. At discharge, 98% of patients had mild or less regurgitation and peak aortic gradient was 16.9 ± 9.5 mm Hg. Two patients underwent aortic valve replacement. At median follow-up of 8.1 months, 96% and 91% of patients had less than moderate regurgitation and stenosis, respectively. CONCLUSIONS The AVRec procedure has acceptable short-term results and should be considered for valve reconstruction in pediatric patients with congenital aortic and truncal valve disease. Longer-term follow-up is necessary to determine the optimal patch material and late valve function and continued annular growth.

Abstract
This article is the latest in an EJCTS series entitled 'The Great Debates'. We have chosen the topic of aortic valve (AoV) surgery in children, with a focus on infants and neonates. The topic was selected due to the significant challenges that AoV problems in the young may present to the surgical team. There are many areas of active controversy, despite the vast accumulated world experience. We have tried to incorporate many of these issues in the questions posed, not claiming to be all-inclusive. The individuals invited to this debate are experts in paediatric valve surgery, with broad and successful clinical experiences on multiple continents. We hope that the facts and opinions presented in this debate will generate interest and discussion and perhaps prove useful in decision-making for future complex valve cases.

Abstract
Background Aortic cusp extension is a subjective and operator-dependent technique. In order to facilitate surgical correction of aortic cusp retraction and reestablishment of adequate cusp coaptation, we sought to develop new templates that can be used to cut flat pericardial sheets into precise cusp extension patches. Methods Each template was designed as a two-dimensional unwrap of the natural geometry of a complete aortic cusp, and a series of templates were made available to correspond with all potential aortic cusp sizes. Based on these templates, aortic cusp extension was performed in 2 patients (aged 54 and 43 years) with significant retraction of the noncoronary aortic cusps and severe aortic valve insufficiency. In each patient, extension of the retracted native noncoronary cusp was undertaken using a bovine pericardial patch that matched the size of adjacent nondiseased native aortic cusps. Results Achieving geometrically perfect aortic cusp extensions was uncomplicated, and intraoperative transesophageal echocardiography confirmed satisfactory aortic valve repairs (aortic insufficiency < 1+ and low transvalvular gradients). Early follow-up transthoracic echocardiography confirmed that all valve cusps met at similar heights in the aortic root, and that their excursions were virtually identical. Conclusions The newly designed templates can be used to cut flat pericardial sheets into exact cusp extension patches, and initial clinical experience indicates that they are useful in performing precise aortic cusp extension procedures and restoring adequate aortic valve competence.

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
BACKGROUND We sought to identify transesophageal echocardiography (TEE) predictors of early reoperation for recurrent aortic regurgitation (AR) after cardiopulmonary bypass (CPB) in patients undergoing repair for congenital aortic valve disease. METHODS We analyzed post-CPB TEEs in patients with congenital aortic valve disease undergoing repair for predominant AR. Case patients underwent reoperation for recurrent AR within 2 years, whereas control patients were free from reoperation for more than 3 years. RESULTS Case patients (n = 22; median time to reoperation 0.3 years) and control patients (n = 22; median freedom from reoperation ≥4.4 years) were similar for demographic characteristics, aortic dimensions, and preoperative AR grade. Among post-CPB TEE variables, univariate logistic regression analysis identified shorter coaptation height (odds ratio [OR] for 1-mm increase 0.72, 95% confidence interval [CI]: 0.54 to 0.95; p = 0.02), decreased ratio of coaptation height to annulus diameter (OR for a 5% decrease 1.37, 95% CI: 1.06 to 1.77; p = 0.02), and increased percentage difference (%diff) between longest and shortest coaptation lengths in a short-axis view (OR for 10% increase 1.84, 95% CI: 1.15 to 2.92; p = 0.01) as risk factors for early reoperation for recurrent AR. Multivariable analysis identified %diff in short-axis coaptation lengths as the strongest post-CPB TEE predictor (area under receiver operator curve = 0.743). The sensitivity and specificity of a %diff of 50% were 0.45 and 0.91, whereas a %diff of 30% had a sensitivity of 0.75 and specificity of 0.67. CONCLUSIONS Coaptation asymmetry, measured as increased %diff in short-axis coaptation lengths on post-CPB TEE, is associated with early reoperation for recurrent AR after congenital valve repair.

Abstract
The short-term surgical results for mixed aortic valve disease (MAVD) and the long-term effects on the left ventricle (LV) are unknown. Retrospective review identified patients with at least both moderate aortic stenosis (AS) and aortic regurgitation (AR) before surgical intervention. A one-to-one comparison cohort of patients with MAVD not referred for surgical intervention was identified. The 45 patients in this study underwent surgical management for MAVD. A control group of 45 medically managed patients with MAVD also was identified. Both groups had elevated LV end-diastolic volume (EDV), elevated LV mass, a normal LV mass:volume ratio (MVR), and a normal ejection fraction. Both groups had diastolic dysfunction shown by early diastolic pulsed-Doppler mitral inflow/early diastolic tissue Doppler velocity z-score. The LV end-diastolic pressure (EDP) was correlated with age (R = 0.4; p = 0.03) and LV MVR (R = 0.4; p = 0.03) but not with AS, AR, or the score combining gradient and LV size. As shown by 6- to 12-month postoperative echocardiograms, aortic valve gradients and AR significantly improved (gradient 65 ± 17 to 28 ± 18 mmHg, p = 0.01; median regurgitation grade moderate to mild; p < 0.01), LV EDV normalized, and LV mass significantly improved (p < 0.01). Diastolic dysfunction was unchanged. Symptoms did not correlate with any measured parameter, but the preoperative symptoms resolved. In conclusion, despite diastolic dysfunction, systolic function is invariably preserved, and symptoms are not correlated with aortic valve function or LV EDP. Current surgical practice preserves LV mechanics and results in short-term improvement in valve function and symptoms.

Abstract
Background: We sought to evaluate the mid-term results of a repair-oriented strategy of the aortic valve in children. Methods: Between February 2007 and November 2011, we performed 39 aortic valve repairs in children. Median age and weight at surgery were 5.5 years (3 days-18 years) and 16.7 kg (2.7-83.5), respectively. A total of 11 (28%) patients had one or more prior surgical or interventional cardiologic procedures. Median intensive care unit and hospital stay were two (1-96) and five (3-96) days, respectively. Median and cumulative follow-up were 12.7 months (15 days-64 months) and 48.9 patient-years, respectively. Results: There were 3 (7.7%) early deaths all in patients undergoing additional complex cardiac procedures. Two (5.1%) patients required early surgical revision. Twenty-six (66%) patients had isolated or mixed aortic stenosis. The median gradient reduced from 62.4 (range 16-144) to 17.6 mm Hg (range 0-51.8), postoperatively ( P = .02). At last follow-up, the median gradient remained largely unchanged at 21.1 mm Hg (0-49; P = .02). Twenty-six (66%) patients had isolated or mixed aortic valve regurgitation (mild in 8 [20%], moderate in 15 [38%], and severe in 6 ([15%] patients). The degree of aortic regurgitation improved in all patients with moderate or severe aortic regurgitation ( P = .04). At last follow-up, two patients had moderate aortic regurgitation. Kaplan Meier freedom from reintervention in the survivors was 95% at three years. Conclusions: A repair-oriented strategy for the aortic valve in children has satisfactory early and mid-term results and remains a promising management option in children with aortic valve disease.

Valve-sparing aortic root replacement and remodeling with complex aortic valve reconstruction in children and young adults with moderate or severe aortic regurgitation.

Abstract
OBJECTIVES The durability of valve-sparing aortic root procedures with aortic regurgitation due to leaflet disease is questioned. Here, we review our experience in combined aortic root and valve reconstruction in children and young adults. METHODS All valve-sparing aortic root procedures from 2000 to 2012 were reviewed, and patients with aortic valve repair beyond resuspension were included. Root procedures were classified as replacement with reimplantation, root remodeling, or aortic annular and sinotubular junction stabilization. The primary end point was structural valve deterioration, a composite of aortic valve reoperation and/or moderate or greater regurgitation at follow-up. RESULTS Thirty-four patients were included during the study period. The surgery consisted of reimplantation in 13 patients, remodeling in 16 patients, and annular and sinotubular junction stabilization in 5 patients. Valve repair consisted of leaflet procedures in 26 patients and subannular reduction in 15 patients. During a median follow-up of 4.2 months (range, 2 weeks-8 years), there were 5 reoperations for aortic valve replacement due to aortic regurgitation, and 2 patients presented with moderate or greater regurgitation. Freedom from structural valve deterioration was 70.1% ± 10.3% at 1 year and remained stable thereafter, although it was significantly worse in the reimplantation group (P = .039). A more severe degree of preoperative aortic regurgitation (P = .001) and smaller graft to aortic annulus ratio (P = .003) were predictors of structural valve deterioration. CONCLUSIONS Valve-sparing root and valve reconstruction can be done with low operative risk and allows valve preservation in most patients. These data should question the assumption that reimplantation is superior when associated with complex valve reconstruction.

Abstract
Valve repair in children and young adults is an attractive alternative to replacement or Ross procedure. In the past, the various valvuloplasty techniques have addressed isolated valve pathology. Recently, however, a holistic approach involving repair of all aortic root structures has evolved and promised to be an excellent alternative to valve replacement. It provides good long-term results and avoids all the drawback of prosthetic valve insertion in this age group. Development of ideal patch material needed for valve repair and better understanding of the anatomy and function of the aortic root may further improve the short- and long-term outcomes of aortic valvuloplasty.

Abstract
The contents of this article were presented in the session “Aortic insufficiency in the teenager” at the congenital parallel symposium of the 2013 Society of Thoracic Surgeons (STS) annual meeting. The accompanying articles detail the approaches of aortic valve repair and the Ross procedure.1,2 The current article focuses on prosthetic valve replacement. For many young patients requiring aortic valve surgery, either aortic valve repair or a Ross procedure provides a good option. The advantages include avoidance of anticoagulation and potential for growth. In other patients, a prosthetic valve is an appropriate alternative. This article discusses the current state of knowledge regarding mechanical and bioprosthetic valve prostheses and their specific advantages relative to valve repair or a Ross procedure. In current practice, young patients requiring aortic valve surgery frequently undergo valve replacement with a prosthetic valve. In STS adult cardiac database, among patients ≤30 years of age undergoing aortic valve surgery, 34% had placement of a mechanical valve, 51% had placement of a bioprosthetic valve, 9% had aortic valve repair, and 2% had a Ross procedure. In the STS congenital database, among patients 12 to 30 years of age undergoing aortic valve surgery, 21% had placement of a mechanical valve, 18% had placement of a bioprosthetic valve, 30% had aortic valve repair, and 24% had a Ross procedure. In the future, the balance among these options may be altered by design improvements in prosthetic valves, alternatives to warfarin, the development of new patch materials for valve repair, and techniques to avoid Ross autograft failure.

Abstract
OBJECTIVE Balloon aortic valvuloplasty (BAV) is the primary therapy for congenital aortic stenosis (AS). Recurrent AS following initial BAV or initial surgical valvotomy (SV) may require a second BAV (BAV2). We sought to determine the longterm outcomes of BAV2. DESIGN We reviewed all cases of BAV2, defined as BAV following primary BAV or SV between 1988 and 2009. Cases were reviewed for pre- and post-BAV2 echocardiographic and procedural details. SETTING Tertiary care dedicated children's hospital. PATIENTS Between 1985 and 2009, 43 patients underwent BAV2 (23 primary SV, 20 primary BAV) at median age 1.9 years (1 month-21 years) and median weight 15 (3.3-55) kg. INTERVENTIONS BAV2 performed following primary SV or primary BAV. MAIN OUTCOME MEASURES We evaluated the following endpoints: ≥ moderate AI post-BAV2, aortic valve replacement (AVR), additional BAV or SV post-BAV2, death and heart transplantation. RESULTS The gradient decreased from 61.4 ± 16.0 mm Hg to 26.0 ± 13.6 post-BAV2 (P < 0.01). Gradient prior to BAV2 was higher in primary SV patients (66 ± 13 mm Hg) than in primary BAV patients (56 ± 18 mm Hg, P = 0.04). 24 patients had no further events after BAV2, while 19 patients (44%) experienced 23 events including: AVR (n = 8), SV (n = 6), BAV3 (n = 2), death (n = 5), and transplant (n = 1). Regression demonstrated that adverse events were associated with higher post-BAV2 gradient (P < 0.01). Repeat intervention on the aortic valve and AVR were associated with higher post BAV2 gradient (P = 0.04, P = 0.01). Prior to BAV2, 7 patients (17%) had AI > mild, compared to 21 (51%) patients after BAV2. Cox regression revealed that primary BAV was associated with development of AI > mild after BAV2 (P < 0.01). CONCLUSION BAV2 is associated with decreased valve gradient, though with an increase in AI. However, residual AS, not AI, is associated with poor outcomes following BAV2. BAV2 effectively treats recurrent AS and postpones need for surgical intervention.

Abstract
OBJECTIVES This study sought to compare outcomes after surgical valvuloplasty and balloon dilation of the aortic valve in neonates and infants. BACKGROUND Surgical techniques of aortic valve repair have improved and there is today controversy on the best approach to treat neonatal congenital aortic valve stenosis. METHODS Retrospective review of data and follow-up of 123 consecutive neonates and infants (35 females, 88 males) undergoing intervention for congenital aortic stenosis. RESULTS From 1977 to 2009, 123 consecutive neonates (<30 days) and infants (31 days to 1 year) underwent relief of congenital aortic stenosis. Median age at procedure was 27 days (6 to 76 days). Twenty-year survival was 80 ± 7%. Fifty-four patients required a re-intervention and freedom from re-intervention was 55 ± 6% at 10 years and 40 ± 6% at 20 years. By multivariate analysis, having the relief of stenosis by balloon valvuloplasty and undergoing initial treatment as a neonate were predictive of re-intervention. Freedom from re-intervention at 5 years was 27% after balloon valvuloplasty versus 65% after surgery. At latest follow-up, an additional 16 patients had moderate or severe stenosis and 8 had regurgitation. Freedom from re-intervention or stenosis was 39 ± 5% at 15 years. By multivariate analysis, balloon valvuloplasty (p < 0.001) and treatment as a neonate (p = 0.003) were again predictive of stenosis or re-intervention. Thirty-five patients ultimately needed a valve replacement. Significant predictor of the requirement of valve replacement was unicuspid aortic valve (p < 0.001). Freedom from valve replacement was 55 ± 7% at 20 years. CONCLUSIONS Surgical valvuloplasty remains the best approach to treat neonates and infants with congenital aortic stenosis. After surgery, a higher proportion of patients remain free of re-intervention than after interventional catheterization and the relief of their stenosis lasts longer.

Abstract
This case report reveals an encouraging long-term follow-up of an aortic valve repair performed in 1962 by Sir Brian Barrett-Boyes. At last follow-up in 2011, 49 years after aortic valve repair, there was only trivial aortic regurgitation. This length of follow-up is considerably longer than that which currently exists in the literature for aortic valve repair.

The novel two-dimensional strain reflects improvement and remodeling of left-ventricular function better than conventional echocardiographic parameters after aortic valve repair in pediatric patients. Pediatr Cardiol 2013; 34:30-8. [PMID: 22660481 DOI: 10.1007/s00246-012-0376-7] [Citation(s) in RCA: 9] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/05/2012] [Accepted: 05/08/2012] [Indexed: 10/28/2022]
Abstract
We aimed to evaluate the outcome and regional and global left-ventricular (LV) function after aortic valve repair in children with congenital aortic valve disease. Thirty-two consecutive patients with a mean age of 12.62 years (4 months to 18 years) undergoing aortic valve repair due to valve stenosis (AS group, n = 21) or aortic regurgitation (AR group, n = 11) were studied during a follow-up period of 12 months regarding change and adaptation of myocardial function using conventional and novel echocardiographic methods, including two-dimensional (2D) strain echocardiogram. Conventional and 2D strain echocardiographic studies were performed and analyzed off-line using commercially available software (EchoPac 6.1.0, GE). Peak aortic valve gradient decreased from 62.04 ± 30.34 mmHg before surgery to 22.80 ± 14.13 mmHg 2 weeks after surgery and to 35.73 ± 22.11 mmHg 12 months after surgery (p = 0.01). The degree of AR decreased significantly to grade 0 in 20 children and to grade I in 12. There was a significant decrease of thickness of the interventricular septum (IVS) and posterior wall resulting in improvement of LV mass index (p = 0.007, p = 0.043, and p = 0.001, respectively). Significant decrease of myocardial thickness was found, especially in the IVS, in the AS group (p = 0.008), and a significant decrease in LV end-diastolic dimension (EDD) was found in the AR group (p = 0.007). 2D strain analysis showed that global peak strain, global systolic strain rate, and global early diastolic strain rates improved significantly for all patients during the study period after aortic valve repair (p < 0.001, p = 0.037, and p = 0.018, respectively). The global strain and strain rates correlated significantly to IVS thickness (r = 0.002 and r = 0.003, respectively), LV mass index (r = 0.02 and r = 0.015, respectively), and EDD (r = 0.26 and r = 0.005, respectively). Aortic valve repair surgery in pediatric patients results in improvement of global and regional systolic and diastolic LV parameters, which was better shown by 2D strain parameters rather than conventional echocardiographic parameters.

Abstract
Aortic valve reconstruction using leaflet grafts made from autologous pericardium is an effective surgical treatment for some forms of aortic regurgitation. Despite favorable outcomes in the hands of skilled surgeons, the procedure is underutilized because of the difficulty of sizing grafts to effectively seal with the native leaflets. Difficulty is largely due to the complex geometry and function of the valve and the lower distensibility of the graft material relative to native leaflet tissue. We used a structural finite element model to explore how a pericardial leaflet graft of various sizes interacts with two native leaflets when the valve is closed and loaded. Native leaflets and pericardium are described by anisotropic, hyperelastic constitutive laws, and we model all three leaflets explicitly and resolve leaflet contact in order to simulate repair strategies that are asymmetrical with respect to valve geometry and leaflet properties. We ran simulations with pericardial leaflet grafts of various widths (increase of 0%, 7%, 14%, 21% and 27%) and heights (increase of 0%, 13%, 27% and 40%) relative to the native leaflets. Effectiveness of valve closure was quantified based on the overlap between coapting leaflets. Results showed that graft width and height must both be increased to achieve proper valve closure, and that a graft 21% wider and 27% higher than the native leaflet creates a seal similar to a valve with three normal leaflets. Experimental validation in excised porcine aortas (n=9) corroborates the results of simulations.

Abstract
Considering the structure and function of the aortic root, changes in the aortic valve leaflets and changes in the geometry of the aortic root are the two primary causes of aortic valve dysfunction. In adults, aortic valve sparing reconstruction has a long history beginning in the 1970s, where tensor fascia was used for leaflet repair in patients with isolated aortic regurgitation and ascending aortic replacement was used in patients with ascending aortic aneurysms or aortic ectasia. Subsequent progress in the 1980s and 1990s led to pericardial leaflet replacement and aortic root re-implantation and remodeling. However, it has not been until the last decade that these concepts and techniques have been applied in younger patients focusing on the conotruncus, valvar apparatus, sino-tubular junction, and ascending aorta.

Abstract
We describe a new procedure of aortic valvuloplasty for aortic valve prolapse in ventricular septal defect with aortic insufficiency syndrome. This technique allows an anatomic and functional aortic valve reconstruction that prevents late failure of aortic valve repair and reoperation. Midterm results demonstrate the feasibility and durability of this new procedure.

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.
