Dysrhythmias in patients with a complete atrioventricular septal defect: From surgery to early adulthood. CONGENIT HEART DIS 2018; 14:280-287. [PMID: 30485659 PMCID: PMC7379716 DOI: 10.1111/chd.12724] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/25/2018] [Revised: 09/25/2018] [Accepted: 11/03/2018] [Indexed: 11/29/2022]
Abstract
Objective Outcomes after surgical repair of complete atrioventricular septal defect (cAVSD) have improved. With advancing age, the risk of development of dysrhythmias may increase. The aims of this study were to (1) examine development of sinus node dysfunction (SND), atrial and ventricular tachyarrhythmias, and (2) study progression of atrioventricular conduction abnormalities in young adult patients with repaired cAVSD. Study design In this retrospective multicenter study, 74 patients (68% female) with a cAVSD repaired in childhood were included. Patients’ medical files were evaluated for occurrence of SND, atrioventricular conduction block (AVB), atrial and ventricular tachyarrhythmias. Results Median age at repair was 6 months (interquartile range 3‐10) and median age at last follow‐up was 24 years (interquartile range 21‐28). SND occurred after a median of 17 years (interquartile range 11‐19) after repair in 23% of patients, requiring pacemaker implantation in two patients (12%). Regular supraventricular tachycardia was observed in three patients (4%). Atrial fibrillation and ventricular tachyarrhythmias were not observed. Twenty‐seven patients (36%) had first‐degree AVB, which was self‐limiting in 16 (59%) and persistent in 10 (37%) patients. One patient developed third‐degree AVB 7 days after left atrioventricular valve replacement. Spontaneous type II second‐degree AVB occurred in a 28‐year‐old patient. Both patients underwent pacemaker implantation. Conclusions Clinically significant dysrhythmias were uncommon in young adult patients after cAVSD repair. However, three patients required pacemaker implantation for either progression of SND or spontaneous type II second‐degree AVB. Longer follow‐up should point out whether dysrhythmias will progress or become more prevalent with increasing age.

Abstract
BACKGROUND Atrial fibrillation (AF) and other supraventricular tachycardias (SVTs) are known complications after surgical repair of atrial septal defect (ASD), but sinus node dysfunction (SND) and complete atrioventricular conduction block (cAVB) may also occur. OBJECTIVE The aim of this study was to examine time course and interrelationship of various dysrhythmias in patients with ASD. METHODS Adult patients (N = 95) with surgically repaired secundum ASD (n = 40), partial atrioventricular septal defect (n = 37) or sinus venosus defect (n = 18), and documented SND, cAVB, AF, and/or other SVT were included. The median age at repair was 13 years (interquartile range [IQR] 6-45 years), and patients were followed for 26 years (IQR 15-37 years) after ASD repair. RESULTS SND was observed in 34 patients (36%), cAVB in 14 (14%), AF in 48 (49%), and SVT in 44 (45%); 37 patients (39%) had ≥2 dysrhythmias. All dysrhythmias presented most often after ASD repair (P < .01), with a median duration of 12 years (IQR 17 days - 32 years) to 16 years (IQR 4 - 28 years) between repair and onset. Development of SND and cAVB late after ASD repair was not related to a redo procedure in 100% and 60% of patients, respectively. SND preceded atrial tachyarrhythmias in 50% (P = .31) and SVT preceded AF in 68% (P = .09) of patients with both dysrhythmias. CONCLUSION A substantial number of dysrhythmias presented (very) late after ASD repair. In most patients, development of late SND and cAVB was not related to redo procedures. In patients with multiple dysrhythmias, a specific order of appearance was not observed.

Abstract
Background: Congenital lesions of the mitral valve are relatively rare and are associated with a wide spectrum of cardiac malformations. The surgical management of congenital mitral valve malformations has been a great challenge. Objectives: The aim of this study was to evaluate the early and intermediate-term outcome of congenital mitral valve (MV) surgery in children and to identify the predictors for poor postoperative outcomes and death. Patients and Methods: In this retrospective study, 100 consecutive patients with congenital MV disease undergoing mitral valve surgery were reviewed in 60-month follow-up (mean, 42.4 ± 16.4 months) during 2008 - 2013. Twenty-six patients (26%) were under one-year old. The mean age and weight of the patients were 41.63 ± 38.18 months and 11.92 ± 6.12 kg, respectively. The predominant lesion of the mitral valve was MV stenosis (MS group) seen in 21% and MR (MR group) seen in 79% of the patients. All patients underwent preoperative two-dimensional echocardiography and then every six months after surgery Results: Significant improvement in degree of MR was noted in all patients with MR during postoperative and follow-up period in both patients with or without atrioventricular septal defect (AVSD) (P = 0.045 in patients with AVSD and P = 0.008 in patients without AVSD). Decreasing trend of mean gradient (MG) in MS group was statistically significant (P = 0.005). In patients with MR, the mean pulmonary artery pressure (PAP) had improved postoperatively (P < 0.001). Although PAP in patients with MV stenosis was reduced, this reduction was not statistically significant (P = 0.17). In-hospital mortality was 7%. Multivariate analysis demonstrated that age (P < 0.001), weight (P < 0.001), and pulmonary stenosis (P = 0.03) are strong predictors for mortality. Based on the echocardiography report at the day of discharge from hospital, surgical results were optimal (up to moderate degree for MR group and up to mild degree for MS group) in 85.7% of patients with MS and in 76.6% of patients with MR. Age (P = 0.002) and weight (P = 0.003) of patients are strong predictors for surgical success in multivariate analysis. Conclusions: Surgical repair of the congenital MV disease yields acceptable early and intermediate-term satisfactory valve function and good survival at intermediate-term follow-up. Strong predictors for poor surgical outcome and death were age smaller than 1 year, weight smaller or equal than 6 kg, and associated cardiac anomalies such as pulmonary stenosis.

Comparison of two surgical techniques for complete atrioventricular septal defect repair using two- and three-dimensional echocardiography. Pediatr Cardiol 2014; 35:393-8.

Abstract
Different surgical techniques for complete atrioventricular septal defect (CAVSD) repair have been described, with the double-patch technique being most frequently employed. More recently a newer technique using a modified single-patch repair has been advocated. We hypothesized that the modified single-patch technique would result in an increased incidence of the two major post-repair comorbidities, namely, distortion of the left AV valve (LAVV) leaflets and narrowing of the left-ventricular outflow tract (LVOT). We studied 14 patients with CAVSD who underwent either traditional double-patch technique [group 1 (n = 7)] or modified single-patch technique [group 2 (n = 7)]. Preoperative and immediate postoperative two-dimensional (2D) echocardiograms, as well as follow-up 2D and three-dimensional (3D) studies, were reviewed. For group 1, the median age at repair was 4.1 months with a median duration from surgical repair and last echocardiogram of 44 months. For group 2, the median age at repair was 3 months with a median duration from surgical repair and last echocardiogram of 28 months. The two groups had similar demographics and ventricular septal defect size before surgery. For the LAVV, no significant difference was observed with respect to LAVV annulus size, tenting height, and the size of the vena contracta. Furthermore, there was no significant difference in the 2D echocardiographic areas and volumes of the LVOT between pre-repair and immediate post-repair studies for both groups. At the last evaluation, although there had been growth of the LVOT in both groups, no significant difference between areas and volumes were observed. Areas of the LVOT measured by 3D echocardiography on the final study showed no significant statistical difference between both groups. There was good correlation of the areas measured by 2D and 3D echocardiography within each group. In this small group, modified single-patch technique does not appear to tether the LAVV or promote an increase in regurgitation. In the short term, LVOT growth is unaffected, and the repair does not promote LVOT obstruction. 3D echocardiography is useful for area measurements of the LVOT and showed good correlation with areas measured by assumption of the LVOT shape as determined using 2D techniques.

Abstract
This study aimed to identify early outcomes of and prognostic factors for left atrioventricular valve (LAVV) reoperation after primary atrioventricular septal defect (AVSD) repair. A retrospective cohort study was performed using the Pediatric Cardiac Care Consortium database, which included 370 patients with previously repaired AVSDs who subsequently underwent LAVV reoperation between 1982 and 2007. Of these patients, 243 underwent LAVV repair, and 127 underwent LAVV replacement. Median time to first reoperation after primary repair was 0.67 years in the repair subgroup and 0.18 years in the replacement subgroup. Thirty-day survival was significantly poorer in the replacement subgroup compared with the repair subgroup (P = 0.0002). In multivariable analysis, independent predictors of earlier time to valve replacement included presence of Down syndrome and postoperative left atrioventricular valve stenosis. Independent predictors of in-hospital death after valve replacement included presence of Down syndrome (hazard ratio [HR] 2.34, 95% CI 1.19-4.58) and prosthetic valve size-to-weight ratio >3 mm/kg (HR 3.02, 95% CI 1.52-6.01). The identification of a subgroup of previously repaired AVSD patients at high risk for early postoperative death after LAVV replacement suggests that for these patients, a low threshold for detailed hemodynamic monitoring and/or reintervention for hemodynamic aberrations is warranted.

Abstract
BACKGROUND Mitral regurgitation is the most common indication for reoperation in children following repair of atrioventricular septal defect (AVSD). We hypothesized that angiotensin-converting enzyme inhibitor therapy would decrease the severity of mitral regurgitation and limit left ventricular volume overload in children following AVSD repair. METHODS The Pediatric Heart Network designed a placebo-controlled randomized trial of enalapril in this population. The primary aim was to test the effect of enalapril on the change in left ventricular end-diastolic dimension body surface area-adjusted z score. Before the launch of the trial, a feasibility study was performed to estimate the number of patients with at least moderate mitral regurgitation following AVSD repair. TRIAL EXPERIENCE Seventeen months after the start of the study, 349 patients were screened, 8 were trial eligible, and only 5 were enrolled. The study was subsequently terminated because of low patient accrual. Several factors led to the problems with patient accrual, including (1) the use of criteria to assess disease severity in the feasibility study that were not identical to those used in the trial, (2) failure to achieve equipoise for the study among clinicians and referring physicians, (3) reliance on methodology developed in adult populations with different disease mechanisms, and (4) absence of adequate data to define the natural history of the disease process under study. Progress in the treatment of children with cardiovascular disease will depend on the future of multicenter collaborative clinical trials. The lessons learned from this study may contribute to improvements in this research.

Abstract
Closure of a mitral valve (MV) cleft, small left-sided cardiac structures, and ventricular imbalance all may contribute to mitral stenosis (MS) after repair of atrioventricular canal (AVC) defects. MV replacement is the traditional therapy but carries high risk in young children. The utility of balloon mitral valvuloplasty (BMV) in postoperative MS is not established and may offer alternative therapy or palliation. Since 1996, 10 patients with repaired AVC defects have undergone BMV at a median age of 2.5 years (range 8 months to 14 years), a median of 2 years after AVC repair. At catheterization, the median value of mean MS gradients was 16 mm Hg (range 12 to 22) and was reduced by 34% after BMV. Before BMV, there was mild mitral regurgitation in 9 of 10 patients, which increased to severe in 1 patient. All patients were alive at follow-up (median 5.4 years). Repeat BMV was performed in 4 patients, 10 weeks to 18 months after initial BMV. One patient underwent surgical valvuloplasty; 3 underwent MV replacement 2, 3, and 28 months after BMV. In the 6 patients (60%) with a native MV at most recent follow-up (median 3.2 years), the mean Doppler MS gradient was 9 mm Hg, the median weight had doubled, and weight percentile had increased significantly. In conclusion, BMV provides relief of MS in most patients with repaired AVC defects; marked increases in mitral regurgitation are uncommon. Because BMV can incompletely relieve obstruction and increase mitral regurgitation, it will not be definitive in most patients but will usually delay MV replacement to accommodate a larger prosthesis.

Abstract
OBJECTIVE Successful mitral valve replacement in young children is limited by the lack of small prosthetic valves. Supra-annular prosthesis implantation can facilitate mitral valve replacement with a larger prosthesis in children with a small annulus, but little is known about its effect on the outcomes of mitral valve replacement in young children. METHODS One hundred eighteen children underwent mitral valve replacement at 5 years of age or younger from 1976-2006. Mitral valve replacement was supra-annular in 37 (32%) patients. RESULTS Survival was 74% +/- 4% at 1 year and 56% +/- 5% at 10 years but improved over time (10-year survival of 83% +/- 7% from 1994-2006). Factors associated with worse survival included earlier mitral valve replacement date, age less than 1 year, complete atrioventricular canal, and additional procedures at mitral valve replacement, but not supra-annular mitral valve replacement. As survival improved during our more recent experience, the risks of supra-annular mitral valve replacement became apparent; survival was worse among patients with a supra-annular prosthesis after 1991. A pacemaker was placed in 18 (15%) patients within 1 month of mitral valve replacement and was less likely in patients who had undergone supra-annular mitral valve replacement. Among early survivors, freedom from redo mitral valve replacement was 72% +/- 5% at 5 years and 45% +/- 7% at 10 years. Twenty-one patients with a supra-annular prosthesis underwent redo mitral valve replacement. The second prosthesis was annular in 15 of these patients and upsized in all but 1, but 5 required pacemaker placement for heart block. CONCLUSIONS Supra-annular mitral valve replacement was associated with worse survival than annular mitral valve replacement in our recent experience. Patients with supra-annular mitral valve replacement were less likely to have operative complete heart block but remained at risk when the prosthesis was subsequently replaced.

Abstract
The number of grown-up patients with congenital heart disease (GUCH) is constantly increasing and will equal the number of children requiring surgery for congenital heart disease (CHD). Specialized centers dealing with the medical and paramedical problems of these patients are required. GUCH patients can be divided into the following groups: (1) patients with minor cardiac malformations presenting at adult age for first treatment; (2) patients presenting for correction as adults because they are either naturally balanced or were surgically palliated; (3) patients presenting for expected reoperations after correction in childhood; (4) patients requiring repair of residual defects after correction; (5) patients developing heart failure after correction or palliation of CHD requiring thoracic transplantation; and (6) patients developing acquired heart disease in addition to CHD. Special aspects of malformations frequently occurring in GUCH patients are discussed in detail. Acquired heart disease in this patient population is expected to increase in the coming decades as survivors of CHD grow old.

Abstract
OBJECTIVES The purpose of this study was to determine whether 3-dimensional echocardiography (3DE) provides additional information regarding the mechanisms and sites of left atrioventricular valve regurgitation in atrioventricular septal defect compared with transesophageal 2-dimensional echocardiography (2DE). METHODS Eleven patients with a median age of 5.4 years (2.9-11.6 years) and a median weight of 16.8 kg (13.7-38.3 kg) with an atrioventricular septal defect underwent simultaneous transesophageal 2DE and 3DE before operation. RESULTS The 2DE-3DE agreement for the assessment of the superior and mural leaflet size was 72.7%. The 2DE-3DE agreement for coaptation failure, a residual or primary cleft, and commissural abnormalities as a mechanism of regurgitation were 72.7%, 63.6%, and 36.4%, respectively. For jet sites the 2DE-3DE agreement was 63.6% for a commissural and central location. CONCLUSION Three-dimensional echocardiography provides new and superior data regarding the mechanisms and sites of left atrioventricular valve regurgitation in atrioventricular septal defect.

Abstract
OBJECTIVE Left atrioventricular valve pericardial patch may prevent valve replacement. We assessed patch annular dynamics compared with conventional repair and normal annuli. METHODS Transesophageal 3-dimensional echocardiography was acquired preoperatively and postoperatively in atrioventricular septal defects (n = 10, 5 patch, 5 conventional repair). Real-time 3-dimensional annular motion at midterm was compared with that of healthy children (n = 10). Parameters were: annular area, perimeter, segmental diameter, bending angle, stenosis, and regurgitation. RESULTS Regurgitant jet area ratio decreased in both patient groups. Conventional repair reduced annular area (P = .02). Patch repair showed an annular area larger than normal (P = .01). Control subjects had increased systolic area whereas operative groups showed a reduction. Patch repair had segmental diameters similar to normal whereas conventional repair was inhomogeneous. Annular bending angle was maintained after operation. CONCLUSION Patch repair in pediatrics shows durability without shrinkage or expansion. Improved stenosis and regurgitation does not change by midterm. Operation causes increased annular stiffness and diminished compliance. Neither technique establishes normal annular eccentricity.

Abstract
We describe two patients who successfully underwent a surgically created double-orifice repair using the edge-to-edge repair for residual left atrioventricular valve (LAVV) regurgitation in an atrioventricular septal defects (AVSD). Both patients had previously received patch closure of the AVSD and partial closure of a cleft of the LAVV. Preoperatively, echocardiography showed a wide open cleft and remarkable dilatation of the LAVV annulus. Doppler study revealed severe regurgitation through the cleft and the central portion of the LAVV orifice and no intracardiac shunt. Postoperative echocardiography showed a remarkable decrease of the AV valve regurgitation to none or trivial levels without stenosis of the LAVV in both patients. Among several valve-sparing techniques, our experience suggests that the surgically created double-orifice repair is one of the most effective reparative procedures for LAVV regurgitation in AVSD.

Abstract
In contrast to older patients, children and young adults rarely have isolated disease of the systemic atrioventricular valve. Stenosis and/or regurgitation of the systemic atrioventricular valve, however, frequently coexist with complex congenital cardiac disease. In addition, most patients undergoing surgery on the systemic atrioventricular valve have had previous intracardiac repairs.

Abstract
BACKGROUND Atrioventricular valve regurgitation represents the principal indication for reoperation after repair of atrioventricular septal defect. Deciding how to correct atrioventricular valve regurgitation is challenging in some cases because of the complexity of the anatomic features. This report deals with our surgical experience in using a double-orifice valve plasty technique in cases with atrioventricular septal defect. METHODS From August 2002 to August 2004, 8 patients underwent double-orifice valve plasty in surgical correction of atrioventricular septal defect. Anatomic types were partial (6 patients), intermediate (1 patient), and complete (1 patient). After the mitral cleft was closed, moderate to severe atrioventricular valve regurgitation was still present in these patients. Double-orifice valve plasty was used in the mitral valve in 7 patients and in the tricuspid valve in 1. RESULTS No hospital deaths or postoperative morbidity occurred. The follow-up ranged from 6 months to 30 months (median, 14.4 months). No or trivial atrioventricular valve regurgitation was found in 6 patients and mild atrioventricular valve regurgitation was present in 2. CONCLUSIONS Double-orifice valve plasty is an easy and effective additional procedure for children and for adult patients who have moderate or severe atrioventricular valve regurgitation after repair of atrioventricular septal defect.

Abstract
BACKGROUND The aims of this study were to determine early and midterm survival and freedom from reoperation, and to identify the predictors for poor postoperative outcome in children undergoing mitral valve (MV) repair owing to congenital malformations of the mitral valve. METHODS Between January 1990 and February 2001, 94 consecutive children with congenital MV disease underwent valve repair. The mean age was 5.2+/-3.3 years (range 20 days to 15 years). Twenty-five (26.6%) children were less than 1 year old. Isolated MV disease was found in 21 (22.4%) patients. MV stenosis was the predominant lesion in 21 (22.4%) patients with a mean left atrial to left ventricle diastolic peak gradient of 24.5+/-9.2 mm Hg. MV regurgitation was the predominant pathophysiology in 73 (77.6%) patients with a mean regurgitation grade of 3.3+/-0.7. RESULTS The hospital mortality was 8.5% (8 of 94). Three patients required permanent pacemaker implantation owing to complete atrioventricular block. Two patients underwent mediastinal exploration for significant bleeding. Postoperatively the echocardiography color Doppler study demonstrated a significantly lower mean end diastolic left atrium to left ventricle gradient 8.7+/-2.2 mm Hg (p < 0.001) in patients with MV stenosis and a mean regurgitation grade of 0.9+/-0.6 (p < 0.001) in patients with MV regurgitation. Actuarial survival and actuarial reoperation-free survival were 89.2% and 76.3%, respectively. Multivariate analysis demonstrated that age less than 1 year (p = 0.035), hammock MV (p = 0.0093), cardiothoracic ratio greater than 0.6 (p < 0.0001), and associated cardiac anomalies (p = 0.003) were strong predictors for poor overall freedom from reoperation and midterm survival. CONCLUSIONS Mitral valve repair for congenital mitral valve disease yields acceptable early and midterm mortality and reoperation rates. Strong predictors for poor overall freedom from reoperation and midterm survival were age less than 1 year, hammock MV, cardiothoracic ratio greater than 0.6, and associated cardiac anomalies.

Abstract
BACKGROUND The objective of this study was to assess the outcome of complete atrioventricular septal defect repair from 1981 to 2000. METHODS One hundred seventy-two consecutive patients with atrioventricular septal defect were operated on by a single surgeon using a consistent operative technique (single patch; "cleft" closure). The patients' age range was from 5 weeks to 9 years (mean, 10.8 +/- 1.2 months). RESULTS Overall operative mortality was 15 of 172 (8.7%) and this decreased significantly from 12 of 73 (16.4%) in the first decade to 3 of 99 (3.0%) in the second decade (p = 0.0021) with no operative deaths in the last 51 patients. Operative mortality was related to decade of operation (p = 0.0021) and to use of crystalloid cardioplegia (p = 0.0047) by univariate analysis, and to decade of operation (p = 0.0016) and postoperative time on ventilator (p = 0.0023) by multivariate analysis. Actuarial long-term survival including operative deaths was 79.0% +/- 3.8% at 15 years. Ten of 157 (6.4%) operative survivors have undergone reoperation for late mitral regurgitation (9 mitral valve repair, 1 mitral valve replacement) with one death. Four of 8 patients surviving late mitral valve replacement have subsequently required mitral valve repair. Freedom from late reoperation for severe mitral regurgitation was 89.9% +/- 3.1% at 15 years. Freedom from late reoperation for mitral regurgitation did not decrease in the second decade (84.2% +/- 6.6% at 10 years) versus the first decade (94.5% +/- 3.1%) (p = 0.0679). CONCLUSIONS Although operative mortality for repair of atrioventricular septal defect has decreased dramatically during the past decade, the incidence of late reoperation for mitral regurgitation has not improved, and better techniques to eliminate late mitral regurgitation are needed.
