Repair of the complete atrioventricular septal defect-impact of postoperative moderate or more regurgitation. INTERDISCIPLINARY CARDIOVASCULAR AND THORACIC SURGERY 2024; 38:ivae053. [PMID: 38569897 PMCID: PMC11055535 DOI: 10.1093/icvts/ivae053] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/13/2023] [Revised: 08/22/2023] [Accepted: 03/19/2024] [Indexed: 04/05/2024]
Abstract
OBJECTIVES To study the risk factors for mortality, moderate or more left atrioventricular valve regurgitation (LAVVR) and reoperation after the surgical repair of complete atrioventricular septal defect (cAVSD) in a single centre. METHODS The current study is a retrospective review of patients who underwent surgical repair of cAVSD between 2000 and 2021. Patients with unbalanced ventricles not amenable to biventricular repair, double outlet right ventricle and malpositioned great arteries were excluded. The clinical predictors of outcome for end points were analysed with univariate and multivariable Cox regression analysis or Fine-Gray modelling for competing risks. Time-dependent end points were estimated using the Kaplan-Meier curve analysis and cumulative incidence curves. RESULTS The median follow-up time was 2.3 years. Among 220 consecutive patients were 10 (4.6%) operative and 21 late mortalities (9.6%). A total of 26 patients were identified to have immediate postoperative moderate or more regurgitation and 10 of them ultimately died. By multivariable analysis prematurity and having more than moderate regurgitation immediately after the operation were identified as predictors of overall mortality (P = 0.003, P = 0.012). Five- and ten-year survival rates were lower for patients with immediate postoperative moderate or more LAVVR {51.9% [confidence interval (CI): 27.5-71.7%]} when compared to patients without moderate or more regurgitation [93.2% (CI: 87.1-96.4%) and 91.3% (CI: 83.6-95.5%)]. CONCLUSIONS The patients who undergo cAVSD repair remain subjected to a heavy burden of disease related to postoperative residual LAVVR. Immediate postoperative moderate or more LAVVR contributes significantly to overall mortality. Whether a second run of bypass can decrease this observed mortality should be investigated.

J Thorac Cardiovasc Surg 2024; 167:1136-1144. [PMID: 37442338 DOI: 10.1016/j.jtcvs.2023.07.003] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/03/2023] [Revised: 06/14/2023] [Accepted: 07/01/2023] [Indexed: 07/15/2023]
Abstract
OBJECTIVE This study compared the mortality, left atrioventricular valve-related reoperation, and left atrioventricular valve competence in symptomatic neonates and small infants who underwent staged repair incorporating pulmonary artery banding or primary repair for complete atrioventricular septal defect. METHODS Patients weighing less than 4.0 kg at the time of undergoing staged (n = 37) or primary (n = 23) repair for balanced complete atrioventricular septal defect between 1999 and 2022 were reviewed. The mean follow-up period was 9.1 years. Freedom from moderate or greater left atrioventricular valve regurgitation was estimated with the Kaplan-Meier method. RESULTS The staged group included smaller children (median weight, 2.9 vs 3.7 kg) and a higher proportion of neonates (41% vs 4%). All patients in the staged group survived pulmonary artery banding and underwent intracardiac repair (median weight, 6.8 kg). After pulmonary artery banding, the severity of left atrioventricular valve regurgitation improved in 10 of 12 patients (83%) without left atrioventricular valve anomaly who had mild or greater left atrioventricular valve regurgitation and a left atrioventricular valve Z score greater than 0. Although survival and freedom from left atrioventricular valve-related reoperation at 15 years (P = .195 and .602, respectively) were comparable between the groups, freedom from moderate or greater left atrioventricular valve regurgitation at 15 years was higher in the staged group (P = .026). CONCLUSIONS Compared with primary repair, staged repair for complete atrioventricular septal defect in children weighing less than 4.0 kg resulted in comparable survival and reoperation rates and better left atrioventricular valve competence. Pulmonary artery banding may mitigate secondary left atrioventricular valve regurgitation unless a structural valve abnormality exists. Selective deferred intracardiac repair beyond the neonatal and small-infancy period may still play an important role in low-weight patients.

The impact of surgical repair on left ventricular outflow tract in atrioventricular septal defect with common atrioventricular valve orifice. JTCVS OPEN 2023; 14:385-395. [PMID: 37425447 PMCID: PMC10328763 DOI: 10.1016/j.xjon.2022.11.023] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/13/2022] [Revised: 09/13/2022] [Accepted: 10/03/2022] [Indexed: 07/11/2023]
Abstract
Objective Although a narrow left ventricular outflow tract in atrioventricular septal defect is related to its intrinsic morphology, the contribution from the repair technique remains to be quantified. Methods A total of 108 patients with an atrioventricular septal defect with a common atrioventricular valve orifice were divided into 2 groups: 2-patch (N = 67) and modified 1-patch (N = 41) repair. The left ventricular outflow tract morphometric was analyzed by quantifying the degree of disproportion between subaortic and aortic annular dimensions (disproportionate morphometrics ratio was defined as ≤ 0.9). Z-scores (median, interquartile range) were further analyzed in a subset of 80 patients with immediate preoperative and postoperative echocardiography. A total of 44 subjects with ventricular septal defects served as controls. Results Before repair, 13 patients (12%) with an atrioventricular septal defect had disproportionate morphometrics (vs 6 [14%] ventricular septal defect P = .79), but the subaortic Z-score (-0.53, -1.07 to 0.06) was lower than the ventricular septal defect (0.07, -0.57 to 1.17; P < .001). After repair, both 2-patch (8 [12%] preoperatively vs 25 [37%] postoperatively; P = .001) and modified 1-patch (5 [12%] vs 21 [51%], P < .001) procedures showed a greater degree of disproportionate morphometrics. Both 2-patch (postoperatively -0.73, -1.56 to 0.08 vs preoperatively -0.43, -0.98 to 0.28; P = .011) and modified 1-patch (-1.42, -2.63 to -0.78 vs -0.70, -1.18 to -0.25; P = .001) procedures also demonstrated lower subaortic Z-scores postrepair. The postrepair subaortic Z-scores were lower in the modified 1-patch group (-1.42 [-2.63 to -0.78]) compared with the 2-patch group (-0.73 [-1.56 to 0.08]; P = .004). Low postrepair subaortic Z-scores (<-2) were observed in 12 patients (41%) in the modified 1-patch group and 6 patients (12%) in the 2-patch group (P = .004). Conclusions Surgical correction resulted in greater disproportionate morphometrics seen immediately postrepair. The impact on the left ventricular outflow tract was observed in all repair techniques, with a greater burden seen after modified 1-patch repair. Video Abstract This morphometric study in AVSD with common atrio-ventricular valve orifice confirmed further derangements of LV outflow tract morphometrics immediately after surgical repair.

J Thorac Cardiovasc Surg 2023; 165:411-421. [PMID: 36115701 DOI: 10.1016/j.jtcvs.2022.07.041] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/12/2022] [Revised: 07/03/2022] [Accepted: 07/21/2022] [Indexed: 01/18/2023]
Abstract
OBJECTIVES We compared 2-patch repair (TP) with modified single-patch repair (MSP) for complete atrioventricular septal defects and evaluated their effect on the left atrioventricular valve (LAVV) competence. We also identified risk factors for unfavorable functional outcomes. METHODS This retrospective study included 118 patients with complete atrioventricular septal defects who underwent intracardiac repair from 1998 to 2020 (MSP: 69; TP: 49). The median follow-up period was 10.4 years. The functional outcome of freedom from moderate or greater LAVV regurgitation (LAVVR) was estimated using the Kaplan-Meier method. RESULTS The hospital mortality was 1.7% (2/118) and late mortality was 0.8% (1/118). Eight patients required LAVV-related reoperation (MSP: 4; TP: 4) and none required left ventricular outflow tract-related reoperation. In the MSP group without LAVV anomaly, the receiver operating characteristic curve analysis revealed that the ventricular septal defect (VSD) depth was strongly associated with moderate or greater postoperative LAVVR, with the best cutoff at 10.9 mm. When stratified according to the combination of intracardiac repair type and VSD depth, the MSP-deep VSD (VSD depth >11 mm) group showed the worst LAVV competence among the 4 groups (P = .002). According to multivariate analysis, weight <4.0 kg, LAVV anomaly, and moderate or greater preoperative LAVVR were independent risk factors for moderate or greater postoperative LAVVR, whereas MSP was not a risk factor. CONCLUSIONS Postoperative LAVVR remains an obstacle to improved functional outcomes. MSP provides LAVV competence similar to TP unless deep VSD is present. The surgical approach should be selected on the basis of anatomical variations, specifically VSD depth.

Abstract
Background: We sought to determine the difference in geometric parameters in the left atrioventricular valve (LAVV) postoperative complete atrioventricular septal defect (CAVSD) compared to the normal heart, and the correlation between geometric and functional parameters for detecting the mechanism of LAVV regurgitation (LAVVR) in CAVSD. Methods: LAVV geometric parameters based on complete and acceptable quality echocardiograms of 18 patients with repaired CAVSD compared with 17 normal controls. LAVVR severity was also quantified by indexed vena contracta (I-VC) (mm) and % jet area/left atrium area (% Jet/LA), and the correlation with LAVV parameters in the CAVSD group was investigated. Results: In the CAVSD group, the posterior closing angle (Pc) was nearly the same as the anterior closing angle (Ac), yet in the normal heart, the Pc angle was double the Ac angle. The anterior opening angle (Ao) and posterior-to-anterior leaflet diameter ratio (a/p) in the CAVSD group was also significantly smaller. The CAVSD group also had a shorter indexed coaptation length (I-CL) and indexed tenting height (I-TH). Displacement length (ΔD) differed completely between the CAVSD and Normal groups, and also showed a strong positive correlation to the functional parameters of LAVVR (% Jet/LA: r = .70, P = .02; I-VC: r = .60, P = .02). Conclusions: The parameters in this study were applicable to CAVSD AV valve coaptation characteristics. We introduced 2 novel measures that may provide important insights into the differences in geometry and performance of the LAVV in repaired CAVSD as compared to normal hearts.

Abstract
Understanding the morphology of atrioventricular septal defects and learning the operative strategies for their repair is one of the more difficult tasks for congenital cardiac surgery residents to master. The modified single-patch technique for several reasons lends itself to being a strategy that is relatively easy to teach residents. It has shorter cross-clamp and bypass times than the standard two-patch technique, which allows more time for the instructor to safely take the resident through the case. The steps of the operation are quite standard and broadly applicable to the wide variety of cardiac morphologies found in children with atrioventricular septal defects. The purpose of this review is to carefully point out the technical details of each step of the modified single-patch technique focusing on teaching the resident surgeon. The ease of teaching this excellent technique is just another reason to use the modified single-patch technique.

Abstract
OBJECTIVES There are limited data available on the height of the ventricular component of the septal deficiency (VSD) in patients undergoing complete atrioventricular septal defect (CAVSD) repair. VSD height may influence optimal choice of repair strategy with potential consequences for long-term outcomes. We aimed to measure VSD height using 2-dimensional echocardiography and review its association with postoperative outcomes. METHODS We retrospectively reviewed the preoperative echocardiograms of 45 consecutive patients who underwent CAVSD repair between May 2010 and December 2015 at a single centre. VSD height and left ventricular length on the four-chamber view were measured. Demographic details and early and late outcomes including reoperation and long-term survival were studied. RESULTS Twenty patients underwent modified single-patch repair and 25 patients underwent double-patch repair of CAVSD. VSD height in the modified single-patch group ranged from 4.2 to 11.7 mm and in the double-patch group ranged from 5.1 to 14.9 mm. Nine patients had a deep ‘scoop’ with a VSD height of >10 mm, (7 double patch, 2 modified single patch). VSD height did not correlate with a specific Rastelli classification. There was no significant difference in the VSD height (P = 0.51) or the VSD height-to-left ventricular length ratio (P = 0.43) between the 2 repair groups. There was no 30-day mortality. Eight patients required reoperation; however, VSD height was not a significant predictor of reoperation (hazard ratio 0.95, 95% confidence interval 0.69–1.33; P = 0.08). CONCLUSIONS There was no correlation between VSD height and risk of reoperation after CAVSD repair. A deep ventricular scoop is uncommon in CAVSD patients.

Abstract
OBJECTIVES Although left ventricular outflow tract (LVOT) obstruction is a recognized risk after atrioventricular (AV) septal defect (AVSD) repair, quantitative assessments to define the substrate of the obstruction are lacking. METHODS Morphometric analyses were based on measurements from early 2-dimensional echocardiographic scans (within 3 months postoperatively) for 117 patients (82 CAVVO = common AV valve; 35 SAVVO = separate AV valve orifices), which were compared to 50 age/weight matched controls (atrial septal defect/ventricular septal defect). Late echocardiographic analyses were performed in 57 patients with AVSD (follow-up range, 1.2-10.7 years). RESULTS Adequate z scores (above -2.5) were observed in 109 (93%) patients with AVSD at the aortic annulus and in 89 (76%) with AVSD in the subaortic area. Compared to the control group, patients with AVSD had lower median z scores at the aortic annulus (-0.64 vs 0.60; P < 0.001) and the subaortic areas (-1.48 vs 0.59; P < 0.001), disproportionate subaortic/aortic annulus ratio <1.00 (67% vs 22%; P < 0.001), narrower annuloaortic-septal angle (94.0 vs 104.0; P < 0.001) and annuloaortic left AV valve angle (78.0 vs 90.0; P < 0.001). Compared to patients with CAVVO, those with SAVVO had narrower annuloaortic-septal angles (P = 0.022) that persisted at late analysis, with lower subaortic/aortic annular ratios (P = 0.039). In patients with CAVVO, lower early postoperative subaortic z scores were found following modified single-patch repairs (median -2.12 vs -1.02 in two-patch repairs; P = 0.004). A total of 6/117 (5%) patients (4 CAVVO, 5% and 2 SAVVO, 6%) required reoperations for LVOT obstruction (mean 6.9 years postoperatively), with no difference in morphology or types of operations. CONCLUSIONS Despite having adequate z scores, patients with AVSD demonstrated abnormal LVOT morphometrics early postoperatively. Besides intrinsic morphology, repair techniques may have an impact on postoperative LVOT morphometrics and requires further evaluation.

Abstract
OBJECTIVES Previous studies investigating risk factors associated with reoperation or mortality after repair of complete atrioventricular septal defect (CAVSD) often have not included sizeable cohorts undergoing modified single-patch repair. Both double patch and modified single-patch techniques have been widely used in Australia since the 1990s. Using a large multi-institutional cohort, we aimed to identify risk factors associated with reoperation or mortality following CAVSD repair. METHODS Between January 1990 and December 2015, a total of 829 patients underwent biventricular surgical repair of CAVSD in Australia at 4 centres. Patients with associated tetralogy of Fallot and other conotruncal abnormalities were excluded. Demographic details, postoperative outcomes including reoperation and survival, and associated risk factors were analysed. RESULTS Fifty-six patients (6.8%) required early reoperation (≤30 days) for significant left atrioventricular valve regurgitation or residual septal defects. Freedom from reoperation at 10, 15 and 20 years was 82.7%, 81.1% and 77%, respectively. Patients without Down syndrome and moderate left atrioventricular valve regurgitation on postoperative echocardiogram were found to be independent risk factors for reoperation. Operative mortality was 3.3%. Overall survival at 10, 15 and 20 years was 91.7%, 90.7% and 88.7%, respectively. Prior pulmonary artery banding was a predictor for mortality, while later surgical era (2010-2015) was associated with a reduction in mortality risk. CONCLUSIONS Improved survival in the contemporary era is in keeping with improvements in surgical management and higher rates of primary CAVSD repair over time. The presence of residual moderate left atrioventricular valve regurgitation on postoperative echocardiography is an important factor associated with reoperation and close surveillance is essential to allow timely reintervention. Primary CAVSD repair at age <3 months should be preferenced to palliation with pulmonary artery banding due to the association of pulmonary artery banding with mortality in the long-term.

Surgical Management for Complete Atrioventricular Septal Defects: A Systematic Review and Meta-Analysis. Pediatr Cardiol 2020; 41:1445-1457. [PMID: 32583199 DOI: 10.1007/s00246-020-02397-w] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/31/2020] [Accepted: 06/12/2020] [Indexed: 10/24/2022]
Abstract
A meta-analysis is performed for a comparison of outcomes between the modified one-patch repair (MPR) and two-patch repair (TPR) for complete atrioventricular septal defects (CAVSD). Electronic databases, including PubMed, Scopus, Embase, and Cochrane Library were searched systematically for the literature which aimed mainly at comparing the therapeutic effects for CAVSD administrated by MPR and TPR. Corresponding data sets were extracted and two reviewers independently assessed the risks of bias. Meta-analysis was performed using Revman 5.3 and Stata 12.0. Fifteen studies meeting the inclusion criteria were included, involving 2076 subjects in total. It was observed that MPR was associated with shorter cardiopulmonary bypass (CPB) and aortic cross-clamp (ACC) times, as compared with TPR. However, no statistical differences were found in terms of size of ventricular septal defects (VSD), reoperation, mortality, implantation of permanent pacemakers, and length of ventilation, hospital and intensive care unit stay. As compared with TPR, MPR is superior in terms of ACC and CPB. However, with regard to reoperation, mortality, length of ventilation, ICU and hospital stay and permanent pacemakers implantation, no significant differences are found between these two procedures. MPR is likely to apply to younger infants with faster completion of surgery. Surgery is recommended between 3 and 6 months of age.

Abstract
Left ventricular outflow tract (LVOT) obstruction is a component of many forms of congenital heart disease, including hypertrophic cardiomyopathy, membranous subaortic stenosis, tunnel subaortic stenosis, and outflow tract obstruction related to atrioventricular septal defects. We have gained a particularly extensive experience with the diagnosis and treatment of hypertrophic cardiomyopathy, having performed septal myectomy in over 3,800 patients. In the setting of this review of LVOT obstruction, we use hypertrophic cardiomyopathy as a template by which other pathologies causing LVOT obstruction can be understood. We review important surgical issues in patient selection, diagnostic evaluation, interpretation of imaging, and operative management. To this end, the review focuses on obstructive hypertrophic cardiomyopathy and then broadens to discuss other pathologies causing LVOT obstruction, with important similarities and differences in their management. These other pathologies share some similar presentations and operative techniques, and at times can be confused with hypertrophic cardiomyopathy, but also have important distinctions of which the surgeon should be aware.

Abstract
The location of the atrioventricular conduction axis in the setting of atrioventricular septal defect has previously been shown by histology and intraoperative recordings. We have now reassessed the arrangement using phase-contrast computed tomography, aiming to provide precise measurements so as to optimize future surgical repairs. We used the system based on an X-ray Talbot grating interferometer using the beamline BL20B2 in a SPring-8 synchrotron radiation facility available in Japan. We analyzed 18 specimens. The atrioventricular node was found within a nodal triangle 1.7 mm from the coronary sinus, with 95% confidence intervals from 1.45 to 2.0 millimeters. The depth of the node from the right atrial endocardium was 1.0 mm, with 95% confidence intervals from 0.73 to 1.34 mm. The overall length of the scooped-out ventricular septum was 30.8 mm, with 95% confidence intervals from 27.5 to 34.1 millimeters. The length from the inferior atrioventricular junction to the take-off of the right bundle branch was 12.8 mm, with 95% confidence intervals from 11.12 to 14.38 mm, giving a ratio of 0.43 for the extent of the axis along the inferior septum, with 95% confidence intervals of 0.38-0.48. The length of the non-branching bundle was 6.6 mm, with 95% confidence intervals from 5.57 to 7.7 mm. The proportion of septum occupied by the non-branching bundle was 0.22, with 95% confidence intervals from 0.18 to 0.26. Our findings confirm previous histological studies, extending them by providing precise measurements to guide placement of sutures during surgical repair.

Abstract
In cardiovascular surgery, reconstruction and replacement of cardiac and vascular structures are routinely performed. Prosthetic or biological materials traditionally used for this purpose cannot be considered ideal substitutes as they have limited durability and no growth or regeneration potential. Tissue engineering aims to create materials having normal tissue function including capacity for growth and self-repair. These advanced materials can potentially overcome the shortcomings of conventionally used materials, and, if successfully passing all phases of product development, they might provide a better option for both the pediatric and adult patient population requiring cardiovascular interventions. This short review article overviews the most important cardiovascular pathologies where tissue engineered materials could be used, briefly summarizes the main directions of development of these materials, and discusses the hurdles in their clinical translation. At its beginnings in the 1980s, tissue engineering (TE) was defined as “an interdisciplinary field that applies the principles of engineering and the life sciences toward the development of biological substitutes that restore, maintain, or improve tissue function” (1). Currently, the utility of TE products and materials are being investigated in several fields of human medicine, ranging from orthopedics to cardiovascular surgery (2–5). In cardiovascular surgery, reconstruction and replacement of cardiac and vascular structures are routinely performed. Considering the shortcomings of traditionally used materials, the need for advanced materials that can “restore, maintain or improve tissue function” are evident. Tissue engineered substitutes, having growth and regenerative capacity, could fundamentally change the specialty (6). This article overviews the most important cardiovascular pathologies where TE materials could be used, briefly summarizes the main directions of development of TE materials along with their advantages and shortcomings, and discusses the hurdles in their clinical translation.

Abstract
BACKGROUND We performed a meta-analysis of studies to determine whether the modified single-patch technique offers benefits when compared to the two-patch repair. The postoperative outcomes examined in this study were cardiopulmonary bypass time, cross-clamp time, duration of mechanical ventilation, intensive care unit length of stay, total hospital length of stay, need for reoperation, need for reoperation for left ventricular outflow tract obstruction or left atrioventricular valve regurgitation, need for pacemaker implantation, and mortality during follow-up. METHODS A review was conducted to identify studies comparing a modified single-patch repair versus two-patch repair. A fixed-effects model was utilized for end points with low heterogeneity and a random-effects model for end points with significant heterogeneity. Meta-regression was also performed to determine the influence of other factors on the variables of interest. RESULTS A total of 964 unique manuscripts were screened, with 10 being included in the final analyses. There were a total of 724 patients, with 353 (49%) having undergone repair utilizing a modified single-patch repair. Mean age at repair for modified single-patch repair and two-patch repair was 8.81 and 9.03 months, respectively. Significant differences were noted in cardiopulmonary bypass time and cross-clamp time with mean difference of -28.53 and -22.69 minutes, respectively. In comparison to the two-patch repair, both times were decreased in modified single-patch repair. No significant difference was noted in any other variables. CONCLUSIONS Modified single-patch repair for atrioventricular septal defects requires less cardiopulmonary bypass and cross-clamp time but does not significantly impact the examined postoperative outcomes.

Abstract
OBJECTIVES The "modified single-patch" technique (Nunn's technique) has become more widely adopted, especially in small infants with common atrioventricular septal defect (CAVSD). In this study, we retrospectively reviewed our surgical experiences of the "modified single-patch" technique with CAVSD patients, including newborns and adults, to reveal the early and midterm clinical results. METHODS There were 233 cases diagnosed with CAVSD undergoing biventricular repair in our hospital from June 2009 to 2016. A total of 197 cases (84.5%) with the "modified single-patch" technique were enrolled in the final analysis, including type A in 106 cases (53.8%), type B in 13 cases (6.6%), type C in 15 cases (7.6%), and intermediate type in 63 cases (32%). Major associated cardiovascular malformations included five cases of unroofed coronary sinus syndrome with LSVC (UCS), five cases of coarctation of the aorta and one case of translocation of the great artery. The median age at operation of the studied 197 cases was 44.3 ± 103.3 months (ranging from 18 days to 58 years old), including two newborns. Detailed information on the "modified single-patch" procedure was described previously, and the other cardiac malformations were repaired simultaneously with surgical repair. RESULTS There were 14 (7.1%) early deaths and 3 (1.5%) late deaths at 3 months and 1 year after the initial operation, respectively. The total mortality rate was 8.1%, and there was no significant difference in mortality among the different age groups (P = .291). Five patients (2.5%) underwent reoperation because of severe mitral insufficiency (MI), and another patient was reoperated for left ventricular outflow tract obstruction 3 years after the initial surgery. Long-term survival in the <3 months group was significantly lower than that in the group of older children (1-18 years old). Of the 180 survivors who were followed up for at least 1 year, the proportion of severe MI began to drop from 26.2% before the operation to 13.8% just 1-week postoperation and continued to decline to the lowest level, 3.4%, at 3 months postoperation. However, MI began to rebound at 3 months and reached 20.8% at 1-year postoperation. The rebound of MI was evident in the (3 months, 6 months) age group and the >18 years age group. However, compared to the preoperation situation, the proportion of severe tricuspid insufficiencies decreased each month from 24.8% to 0.0% until 3 months after the operation and remained at a relatively low level within 1 year after surgery. CONCLUSIONS In our experience, age is not a limitation of the modified single-patch technique, and patients even in adults with surgical indications can apply this technique. In older children and adults, we should pay more attention to atrioventricular valve annuloplasty. Infants may suffer from severe residual left atrioventricular valve regurgitation, especially in the <3 months age group, so we should improve postoperative follow-up work during infancy.

Abstract
Biventricular repair of complete atrioventricular septal defect (CAVSD) is largely achieved using the double-patch (DP) or modified single-patch (MSP) techniques in the current era; however, long-term results following MSP repair are not well defined. We aimed to compare long-term outcomes including reoperation and mortality after CAVSD repair using DP and MSP techniques, and identify the risk factors associated with adverse outcomes. A retrospective cohort study was performed including all patients who underwent CAVSD repair using DP and MSP techniques at our institution between 17 May 1990 and 14 December 2015. Demographic details, early (≤30 days) and late (>30 days) outcomes (reoperation, mortality) were studied. Competing risks analysis with cumulative incidence function was used for survival analyses. Overall, 273 consecutive patients underwent CAVSD repair (120 DP and 153 MSP) and 41 patients required reoperation during follow-up. Competing risks analysis showed no association between repair technique and reoperation (P = 1.0) or mortality (P = 0.9). Considering competing risks due to mortality, the cumulative incidence of reoperation at 5, 10, and 15 years was 14%, 17%, and 17% for DP and 12%, 13%, and 16% for MSP, respectively. Non-Down syndrome and moderate or greater left atrioventricular valve regurgitation were predictors for reoperation. Pulmonary artery banding was predictive of mortality, though strongly associated with earlier surgical era. Median follow-up duration was 8.0 years (interquartile range 3.9-20.8) for DP and 11.6 years (interquartile range 5.4-16.1) for MSP (P = 0.4). Event-free survival is similar after DP and MSP repair of CAVSD indicating either repair technique can be safely utilized.

Abstract
Abstract
OBJECTIVES
To compare the long-term performance of the Nunn and 2-patch techniques for the repair of complete atrioventricular septal defects.
METHODS
Between January 1995 and December 2015, a total of 188 patients (Nunn n = 41; 2-patch n = 147) were identified from hospital databases. Univariable Cox regression was performed to calculate the risk of reintervention in each group. Propensity score matching was used to balance the Nunn group and the 2-patch group.
RESULTS
Baseline characteristics including age at surgery, weight, trisomy 21, other cardiac anomalies, previous operations and preoperative atrioventricular valve regurgitation did not differ between the 2 groups. Overall, there was no difference in mortality between the 2 groups (P = 0.43). Duration of cardiopulmonary bypass (CPB) and myocardial ischaemia time were 29 min (P < 0.001) and 28 min (P < 0.001) longer, respectively, in the 2-patch group. Median follow-up was 10.8 years (2–21 years). Unadjusted Cox regression did not reveal a significant difference in the risk of reoperation for either group 9 years after initial surgery [hazard ratio (HR) (Nunn) 0.512, 95% confidence interval 0.176–1.49; Nunn 89%; 2-patch 82%]. This finding was reiterated from Cox regression performed on the propensity-matched sample (31 pairs). The probability of freedom from moderate or worse left atrioventricular valve regurgitation or left ventricular outflow obstruction was similar in the 2 groups.
CONCLUSIONS
The Nunn and 2-patch techniques are comparable in terms of the long-term mortality and probability of freedom from reoperation, moderate or severe left atrioventricular valve regurgitation and left ventricular outflow obstruction. However, the duration of CPB and myocardial ischaemia is longer in the 2-patch group.

Abstract
Objective: The follow-up results of patients operated for atrioventricular septal defect (AVSD) during 1996–2016 at Başkent University are presented. Methods: Data obtained from hospital records consists of preoperative echocardiographic and angiographic details, age and weight at surgery, operative details, Down syndrome presence, postoperative care details, early postoperative and latest echocardiographic findings and hospitalization for reintervention. Results: A total of 496 patient-files were reviewed including 314 patients (63.4%) with complete and 181 (36.6%) with partial AVSD (48.4% of all patients had Down syndrome). Atrioventricular (AV) valve morphology was Rastelli type A in 92.2%, B in 6.5%, and C in 1.3% of patients. The operative technique used was single-patch in 21.6% (108), double-patch in 25.8% (128), and modified single-patch (Wilcox) in 52.5% (260) of patients. The follow-up time was 37.79±46.70 (range, 0–198) months. A total of 64 patients (12.9%) had arrhythmias while in the intensive care unit; pacemaker was implanted in 12 patients. A total of 78 patients (15.7%) were treated for pulmonary hypertensive crisis. The early morbidity and mortality in the postoperative first month were calculated as 38% and 10%, and the late morbidity and mortality (>1 month) were calculated as 13.1% and 1.9%, respectively. The rate of reoperation in our cohort was 8.9%. Conclusion: Although the early morbidity and mortality are low in AVSD operations, the rate of reoperations for left AV valve insufficiency are still high. Although Down syndrome is not a risk factor for early mortality, the co-morbid factors, such as longer postoperative mechanical ventilator or inotropic support, lead to higher risk for morbidity. The frequency of pulmonary hypertension and consequent complications are also high.

Abstract
BACKGROUND Contemporary outcomes of complete atrioventricular septal defect (CAVSD) repair, particularly for defects with associated abnormalities, is unclear. The goal of this study is to report an all-inclusive experience of CAVSD repair using a consistent surgical approach. METHODS All patients undergoing CAVSD repair between 1995 and 2016 at our institution were included. Patients were divided into 2 groups: isolated and complex (tetralogy of Fallot, aortic arch repair, double outlet right ventricle, and total anomalous pulmonary venous return). Survival and reoperation were analyzed using log-rank test and Gray's test, respectively. Multivariable analysis was performed with Cox regression. RESULTS Overall, 406 patients underwent repair: 350 (86%) isolated and 56 (14%) complex CAVSD (tetralogy of Fallot: 34, double outlet right ventricle: 7, aortic arch repair: 12, total anomalous pulmonary venous return: 3). Median age at repair was 5 months (range, 10 days to 16 years); 339 (84%) had trisomy 21. A 2-patch repair was used in 395 (97%) and the zone of apposition was completely closed in 305 (75%). Perioperative mortality was 2% and 4% in the isolated and complex groups, respectively. Perioperative mortality since 2006 was 0.9%. Median follow-up was 7 years. Overall 10-year survival and incidence of any reoperation were 92% and 11%, respectively. Complex anatomy was not a risk factor for mortality (p = 0.35), but it was for reoperation (hazard ratio [HR]: 2.6; p < 0.01). Risk factors for left atrioventricular valve reoperation were a second bypass run (HR: 2.7) and preoperative moderate or worse regurgitation (HR: 2.3). CONCLUSIONS Mortality after CAVSD repair is low, yet reoperation remains a significant problem. Repair of complex CAVSD can be performed with similar mortality rates.

Abstract
Atrioventricular septal defect (AVSD) is a common congenital cardiac surgical problem. Over the years, younger and smaller infants are having operations for this condition before irreversible cardio pulmonary changes occur. Traditionally a single or two patch techniques have been used to repair this defect. However, in the past two decades an innovative method of modified single patch technique popularized by Dr. Graham Nunn has gained worldwide popularity. This review discusses the origin, surgical principles, technique and outcomes of this method, popularly known as Nunn or Australian technique. Research comparing the modified single patch technique to classic single and double patch techniques has shown good preservation of atrioventricular valve function, no residual ventricular septal defect (VSDs), low incidence of left ventricular outflow obstruction, preserved conduction, easy reproducibility, and improved perioperative and long-term mortality.

Abstract
Technical selection for surgical repair of complete atrioventricular septal defect (CAVSD) still remains controversial. This meta-analysis aimed to compare the modified single-patch (MP) technique with the two-patch (TP) technique for patients with CAVSD. Relevant studies comparing the MP technique with the TP technique were identified through a literature search using MEDLINE, EMBASE, Google Scholar, Cochrane Library, and the China National Knowledge Infrastructure databases. The variables were ventricular septal defect (VSD) size, cardiopulmonary bypass (CBP) time, aortic cross-clamp (ACC) time, intensive care unit stay, hospital stay, and other outcomes involving mortality, left ventricular outflow tract obstruction, atrioventricular valve regurgitation, residual septal shunt, atrioventricular block, and reoperation. A random-effect/fixed-effect model was used to summarize the estimates of mean difference/odds ratio with 95% confidence interval. Subgroup analysis stratified by region was performed. Fifteen publications involving 1034 patients were included. This meta-analysis demonstrated that (1) VSD size in the MP group was significantly smaller; (2) CBP time, ACC time, and hospital stay in the MP group experienced improvement; (3) Other postoperative outcomes showed no significant differences between two groups; and (4) The trends in China and other countries were close. The MP and TP techniques had comparable outcomes; however, the MP technique was performed with significantly shorter CBP and ACC times in patients with smaller VSDs. Given this limitation of data, the results of comparison of the two techniques in patients with larger VSDs remain unknown. Further studies are needed.

Abstract
We describe a more physiological technique of complete atrioventricular septal defect repair which restores normal heart anatomy with the offset between the insertions of the mitral and tricuspid valves. This technique overcomes the drawbacks of the previous approaches, and may improve surgical outcomes, particularly in small infants with high ventricular septal defect component or dextroposed aorta.

Abstract
Objective: Since April 2010, our institution has repaired complete atrioventricular septal defects (CAVSDs) with a two-patch technique utilizing CorMatrix extracellular material. This material is potentially an attractive patch because of its theorized eventual integration with the host tissue. We sought to analyze initial outcomes of CAVSD repair with CorMatrix. Methods: Data were collected on consecutive pediatric (age <18) patients receiving two-patch CAVSD repairs with CorMatrix at a single institution from April 2010 to July 2014. Baseline and perioperative characteristics were evaluated. Echocardiograms were evaluated in both the immediate postoperative period and the most recent postoperative follow-up. Variables analyzed included left AV valve performance, residual shunting, left ventricular outflow tract (LVOT) gradient, morbidity, and mortality. Results: Fifteen patients were identified. The average age at operation was 205 days, with mean follow-up time at 1,364 days. Echocardiograms revealed the following: 12 (80%) patients showed either improved or stable left AV valve performance remaining at “mild” or less insufficiency, while two (13%) declined from “none” to mild and one (7%) from mild to “severe,” which required reoperation. There was no residual shunting or LVOT obstruction at follow-up. The single (7%) reoperation was performed after three years due to left AV valve zone of apposition dehiscence. No permanent pacemakers were needed, and no deaths were reported. Conclusion: Our initial experience with CorMatrix in the repair of CAVSD in children has resulted in good initial and midterm outcomes. The CorMatrix patch remained stable through midterm follow-up, thus may be efficacious for use in CAVSD repair.

Abstract
OBJECTIVES This review summarizes the current understanding of the pathophysiology and perioperative management of patent ductus arteriosus, atrial septal defect, ventricular septal defect, and atrioventricular septal defect. DATA SOURCE MEDLINE and PubMed. CONCLUSIONS The four congenital cardiac lesions that are the subject of this review, patent ductus arteriosus, atrial septal defect, ventricular septal defect, and atrioventricular septal defect, are the most commonly found defects causing a left-to-right shunt. These defects frequently warrant transcatheter or surgical intervention. Although the perioperative care is relatively straightforward for many of these patients, there are a number of management strategies and complications associated with each intervention. The treatment outcomes for all of these lesions are very good in the current era.

Abstract
BACKGROUND We evaluated the outcomes of patients undergoing surgical repair of partial atrioventricular septal defect (AVSD) and analyzed the effect of age on outcome. METHODS In this single-center retrospective study, we included all children who underwent repair of partial AVSD between 1990 and 2014. We divided the patients into 4 age quartiles (first quartile: 0-0.75 years, n = 22; second quartile: 0.75-1.5 years, n = 21; third quartile: 1.5-3.75 years, n = 22; and fourth quartile: >3.75 years, n = 21). These quartiles were evaluated for their association with the time-to-event outcomes of survival, freedom from left atrioventricular valve regurgitation (LAVVR), and freedom from reoperation using log-rank analysis. RESULTS During the study period, 86 patients underwent partial AVSD repair at a median age of 1.5 years. There were no operative deaths and 2 late deaths (unknown cause and trauma). There were 13 reoperations. The most common cause of reoperation was left ventricular outflow tract obstruction (LVOTO) (5 patients [first quartile, 2 cases; second quartile, 1 case; third quartile, 2 cases, and fourth quartile, 0 cases]). LAVV reoperation for insufficiency or stenosis was performed in 4 patients (first quartile, 1 case; second quartile, 1 case; third quartile, 1 case; and fourth quartile, 1 case). Two patients underwent pacemaker placement (second quartile, 1 case and fourth quartile, 1 case). There were no statistically significant differences in the most common complications-LVOTO, LAVVR, and AV heart block-between the 4 age quartiles. Median follow-up was 7.1 years (interquartile range [IQR], 0.8-11.4 years). On echocardiography, 72 patients (84%) had less than or equal to mild LAVVR, 8 (9%) patients had mild to moderate LAVVR, 5 (6%) patients had moderate LAVVR, and 1 (1%) patient had severe LAVVR. Age at repair had no significant association with degree of late AV valve insufficiency. CONCLUSIONS Results of partial AVSD repair at a median age of 1.5 years are excellent. Operating at this age is not associated with increased mortality, reoperation, or LAVVR.

Abstract
OBJECTIVES Parachute left atrioventricular (AV) valve can complicate repair of common atrioventricular canal (CAVC), and single-ventricle palliation is sometimes preferred. The goal of this study is to review our single institutional experience in biventricular repair in this patient group. METHODS The demographic, procedural and outcome data were obtained for all children who underwent biventricular repair for complete CAVC with parachute [single left ventricular (LV) papillary muscle] or forme fruste parachute left AV valve (closely spaced LV papillary muscles) from 2001 to 2012. Primary outcomes were survival, freedom from left AV valve stenosis (defined as an inflow gradient ≥7 mmHg and post-capillary pulmonary hypertension) and freedom from left AV valve replacement. RESULTS A total of 24 patients were included (21 parachutes, 3 forme frustes). There was 1 early death (4.2%). At discharge, no patient had more-than-mild regurgitation and 1 had stenosis. During a median follow-up of 3.7 years (IQR 4 months to 5 years), there were 2 late deaths (8.3%), 6 patients (25%) presented significant left AV valve stenosis and 2 patients (8.3%) required valve replacement. Freedom from stenosis was 95 ± 4.9% at 1 year, 83.1 ± 8.9% at 3 years, 64.7 ± 13.5% at 5 years and 51.7 ± 15.8% at 10 years. Complete cleft closure was not associated with a significantly different freedom from left AV valve reoperation (log-rank test, P = 0.89) or significant stenosis (P = 0.47). CONCLUSION Biventricular repair in parachute left AV valve and CAVC is feasible with acceptable mortality and freedom from stenosis. The burden of reoperation remains significant in this patient group.

[PMID: 25825201 DOI: 10.1016/j.athoracsur.2015.01.032] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/07/2014] [Revised: 12/31/2014] [Accepted: 01/06/2015] [Indexed: 10/23/2022]
Abstract
BACKGROUND When the modified single-patch technique for atrioventricular septal defect (AVSD) repair was introduced by Dr Benson Wilcox, there was concern that these patients might be at risk for late subaortic stenosis and left ventricular outflow tract obstruction (LVOTO). This review evaluated our modified single-patch population for LVOTO in the postoperative period. METHODS Between January 2000 and 2013, 77 infants underwent AVSD repair with a modified single-patch technique. Median age was 4.2 months, and median weight was 5 kg. Eight patients had a prior repair of coarctation of the aorta via left thoracotomy in the newborn period. RESULTS The median hospital stay was 10 days. No patient required a pacemaker. The mean and median follow-up times were 4.6 and 3.7 years, respectively. Only 2 patients (2.5%) required reoperation for LVOTO; both had prior repair of coarctation of the aorta (2 of 8 vs 0 of 69, p = 0.01). A discrete fibrous subaortic membrane developed in the first patient that required resection at 3 and 7 years after repair. The other patient had LVOTO from accessory chordae of the left atrioventricular valve and required mitral valve replacement 5 months after repair. One early death occurred at 4 months postoperatively due to liver failure related to hyperalimentation. CONCLUSIONS At intermediate term follow-up, LVOTO does not appear to be a significant postoperative issue after modified single-patch repair of AVSD. Coarctation of the aorta was the most significant predictor of late LVOTO after repair of AVSD with the modified single-patch technique.

Abstract
Background: Two-patch, single-patch, and modified single-patch repairs are accepted techniques for repair of complete atrioventricular (AV) canal defects. We propose a novel, alternative technique: the central patch technique. Methods: For the central patch technique, the superior and inferior bridging leaflets are attached with simple sutures to the right and left of their coaptation point. Both bridging leaflets are incised along a line above the ventricular crest, similar to a traditional single-patch technique. An oval pericardial patch is sewn to the central defect created in the AV valve tissue. Interrupted, horizontal mattress sutures are placed along the ventricular crest, through the midline of the central patch and through the edge of the atrial septal defect (ASD) patch. Tying the sutures simultaneously closes the ventricular septal defect (VSD) and secures the ASD patch to the ventricular crest. Repair of the left AV valve and ASD closure are performed in the routine fashion. Results: Five patients underwent the central patch technique repair of complete AV canal defect. Weight was 4.8 to 6.3 kg; age was four to eight months. Cardiopulmonary bypass and myocardial times averaged 137 minutes and 109 minutes, respectively. No patient had more than mild left AV valve regurgitation or trivial residual VSD at completion of repair. No patient developed left ventricular outflow tract obstruction. Conclusion: The central patch technique is applicable to all forms of complete AV canal defect. Subjectively, it offers technical advantages compared to standard techniques and may result in a shorter learning curve for junior congenital heart surgeons. Results are preliminary but are consistent with standard techniques.

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
Left ventricular outflow tract obstruction (LVOTO) is an important source of morbidity and mortality after repair of atrioventricular septal defect (AVSD). The intrinsic anatomy of the left ventricular outflow tract in AVSD is complex and predisposes to the development of LVOTO. LVOTO after repair of AVSD usually involves multiple levels and sources of obstruction, and surgical intervention must address each component of the obstruction. This includes fibromuscular obstruction, septal hypertrophy, and valve related sources of obstruction. Special attention is also directed to the anterolateral muscle bundle of the left ventricle, a well defined but under recognized feature of the left ventricular outflow tract in AVSD. It is present in all patients with AVSD, and resection of a hypertrophic anterolateral muscle bundle of the left ventricle should be incorporated in all operations for LVOTO after repair of AVSD. LVOTO after repair of AVSD has several unique features that must be taken into consideration to maximize outcome after surgical intervention. These include anatomic factors, technical aspects of surgical intervention, and proper selection of the operation used for relief of LVOTO.

Abstract
BACKGROUND We compared the outcomes of modified single-patch and two-patch surgical repair of complete atrioventricular septal defect (CAVSD) on left ventricular outflow tract (LVOT) diameter and on left atrioventricular valve (LAVV) coaptation. METHODS We reviewed retrospectively postoperative 2-dimensional echocardiograms of all CAVSD patients who underwent modified single-patch or two-patch repair between 2005 and 2011. We measured the leaflet coaptation length of the LAVV in the apical four-chamber view. The LVOT was measured in the long axis view. RESULTS Fifty-one patients underwent CAVSD repair at a median age of 4 months (range, 1 to 9 months) (single-patch, n=29; two-patch, n=22). The images from 46 echocardiograms were adequate for analysis. Modified single-patch repair required significantly shorter bypass time (102.0±33.6 vs 152.9±39.5 minutes, p<0.001) and ischemic time (69.0±21.7 vs 106.9±29.7 minutes, p<0.001) than did two-patch repair. The indexed coaptation length of the septal and lateral leaflets was not different between single-patch and two-patch (3.1±2.3 vs 4.1±3.1 mm/m2, p=0.25; 2.3±2.3 vs 3.3±3.0 mm/m2, p=0.21). Indexed LVOT diameter was not different in the two groups (26.1±5.2 vs 28.5±7.1 mm/m2, p=0.22). There was no hospital or late death during the median follow-up time of 35 months (range, 1 to 69 months). Five patients underwent reoperation after single-patch repair (3 with residual ventricular septal defect [VSD] and LAVV regurgitation, 1 with residual VSD, 1 with pacemaker implantation). After the two-patch repair, 1 patient required reoperation for a residual VSD and right atrioventricular valve regurgitation (p=0.22). CONCLUSIONS The modified single-patch repair was performed with significantly shorter bypass time and myocardial ischemic time. The postoperative LVOT diameter and LAVV leaflet coaptation length were not significantly different between techniques.

Abstract
BACKGROUND Long-term outcomes of repair of tetralogy of Fallot associated with complete atrioventricular septal defect are seldom reported. We report our survival and reintervention outcomes over a 29-year time period. METHODS Between March 1979 and April 2008, 61 patients with the combined cardiac defect of atrioventricular septal defect and tetralogy of Fallot were surgically managed. Trisomy 21 was present in 49 (80%) patients. Primary repair was performed in 36 patients at a median age of 9 months (range, 1 month to 16 years), whereas 25 patients had initial palliation by systemic-pulmonary shunt at a median age of 21 months (range, 0 days to 36 years). Thirty-one (51%) patients had a transannular patch. Fifty-three patients required right ventriculotomy for relief of the right ventricular outflow tract obstruction. Four patients had a right ventricle-pulmonary artery conduit with a homograft. Relationships between patient characteristics and outcome variables were examined using Kaplan-Meier survival curves; comparisons were performed using the log-rank test. RESULTS Median follow-up was 4.7 years. A total of 12 patients died during the course of follow-up: 4 (7%)deaths within 30 days of surgery and 8 late deaths (range, 4 months to 9.9 years after repair). Since 2000, there have been no early deaths and 1 late death, 5 months after the operation. The estimated survival at 5 years after definitive repair was 82% (95% confidence interval, 69%, 90%). Time to death was not associated with any patient or surgical variables examined. Overall, 30% of the survivors required a reoperation. The type of reoperations was on the mitral valve (4 repairs, 4 replacements) and 7 pulmonary valve replacements. We did not find an effect of era on mortality (P = .23 for comparison of 1979-1989, 1990-1999, and 2000-2008). The percentage of patients with primary repair did not change during the different quartiles. The estimated freedom from reoperation at 5 years was 80% (65%, 90%). Time to reoperation was shorter for patients with a conduit (P = .01). CONCLUSIONS Excellent long-term survival was achieved after repair of tetralogy of Fallot associated with complete atrioventricular septal defect. Palliation and primary repair resulted in comparable outcomes; as such, primary repair is favored. The choice of right ventricular outflow tract reconstruction affects the need for reoperation.

Abstract
OBJECTIVES We sought to evaluate the contemporary results after repair of a complete atrioventricular septal defect and to determine the factors associated with suboptimal outcomes. METHODS The demographic, procedural, and outcome data were obtained within 1 and 6 months after repair of a complete atrioventricular septal defect in 120 children in a multicenter observational study from June 2004 to 2006. RESULTS The median age at surgery was 3.7 months (range, 9 days to 1.1 years). The type of surgical repair was a single patch (18%), double patch (72%), and a single atrial septal defect patch with primary ventricular septal defect closure (10%). The incidence of residual septal defects and the degree of left atrioventricular valve regurgitation (LAVVR) did not differ by repair type. The median interval of intensive care stay were 4 days, ventilation use 2 days, and total hospitalization 8 days. All were independent of the presence of trisomy 21 (80% of the cohort). The in-hospital mortality rate was 2.5% (3/120). The overall 6-month mortality rate was 4% (5/120). The presence of associated anomalies and younger age at surgery were independently associated with a longer hospital stay. The age at repair was not associated with residual ventricular septal defect or moderate or greater LAVVR at 6 months. Moderate or greater LAVVR occurred in 22% at 6 months, and the strongest predictor for this was moderate or greater LAVVR at 1 month (odds ratio, 6.9; 95% confidence interval, 2.2-21.7; P < .001). CONCLUSIONS The outcomes after repair of complete atrioventricular septal defect did not differ by repair type or the presence of trisomy 21. An earlier age at surgery was associated with increased resource use but had no association with the incidence of residual ventricular septal defect or significant LAVVR.
