Abstract
OBJECTIVES A double orifice of the left atrioventricular valve (LAVV) associated with atrioventricular septal defects (AVSD) can significantly complicate surgical repair. This study reports our experience of AVSD repair over 3 decades, with special attention to the zone of apposition (ZoA) of the main orifice, and presents a technique of hemivalve pericardial extension in specific situations. METHODS We performed a retrospective study from 1987 to 2016 on 1067 patients with AVSD of whom 43 (4%) had a double orifice, plus 2 additional patients who required LAVV pericardial enlargement. Median age at repair was 1.3 years. Mean follow-up was 8.2 years (1 month-32 years). RESULTS Associated abnormalities of the LAVV subvalvular apparatus were found in 7 patients (5 parachute LAVV and 2 absence of LAVV subvalvular apparatus). ZoA was noted in 4 patients (9%): partially closed in 15 (35%) and completely closed in 24 (56%). Four patients required, either at first repair or secondarily, a hemivalve enlargement using a pericardial patch without closure of the ZoA. The early mortality rate was 7% (n = 3), all before 2000. Two patients had unbalanced ventricles and the third had a single papillary muscle. There were no late deaths. Six patients (14%) required 7 reoperations (3 early and 4 late reoperations) for LAVV regurgitation and/or dysfunction, of whom 4 (9%) required mechanical LAVV replacement (all before 2000). Freedom from late LAVV reoperation was 97% at 1 year, 94% at 5 years and 87% at 10, 20 and 30 years. Unbalanced ventricles (P = 0.045), subvalvular abnormalities (P = 0.0037) and grade >2 LAVV postoperative regurgitation (P = 0.017) were identified as risk factors for LAVV reoperations. Freedom from LAVV mechanical valve replacement was 95% at 1 year, 90% at 5 years and 85% at 10, 20 and 30 years. An anomalous LAVV subvalvular apparatus was identified as a risk factor for mechanical valve replacement (P = 0.010). None of the patients who underwent LAVV pericardial extension had significant LAVV regurgitation at the last follow-up examination. CONCLUSIONS Repair of AVSD and double orifice can be tricky. Preoperative LAVV regurgitation was not identified as an independent predictor of surgical outcome. LAVV hemivalve extension appears to be a useful and effective alternate surgical strategy when the ZoA cannot be closed.

Abstract
We report a case of a 55-year-old male who had been diagnosed with mitral regurgitation and atrial septal defect 5 years earlier. He was referred to our institution because of worsening of mitral regurgitation accompanied by exertional dyspnea. As an echocardiography showed atrioventricular valve regurgitation and ostium primum atrial septal defect, but without ventricular septal defect, he was diagnosed as having partial atrioventricular septal defect (pAVSD). An operation was performed through median sternotomy. The anterior atrioventricular leaflet had a cleft and thickening with calcification. Suturing the cleft could not control the regurgitation. Incomplete coaptation was seen at the edge of the anastomosis site of the cleft, where the severe calcification had been identified. A rough zone including a part of the chordae tendineae was sutured in order to compensate for the gap. The atrioventricular septal defect was closed with an autologous pericardial patch. He was discharged uneventfully on the 24th postoperative day and has been followed up without complications for 1.5 years.

Abstract
OBJECTIVES The incidence of recurrent left atrioventricular valve (LAVV) regurgitation is generally high after repair of partial atrioventricular septal defect (AVSD). This study aimed to evaluate the effect of implanting an additional annuloplasty band into the LAVV during partial AVSD repair and to assess the late outcomes of recurrent LAVV regurgitation. METHODS This study enrolled 133 patients who underwent repair of partial AVSD at our institution from January 2005 to December 2015. All patients underwent repair of the ostium primum atrial septal defect and closure of the LAVV cleft; 37 patients underwent additional annuloplasty band implantation. To minimize differences in preoperative data, propensity score matching was used to identify 33 well-matched patient pairs. RESULTS Cardiopulmonary bypass time and aorta cross-clamp time were significantly longer in the band implantation group (P < 0.05). The 2 groups had similar durations of intensive care and hospital stay (P > 0.05). There was 1 in-hospital death in the band implantation group. During follow-up, conduction block occurred in 6 patients in each group. After follow-up of more than 10 years, freedom from late recurrent LAVV regurgitation was 91% in the band implantation group and 57% in the isolated cleft closure group (P < 0.05). In patients with preoperative severe regurgitation and moderate/mild regurgitation, the rates of freedom from recurrent LAVV regurgitation were 85% and 37%, respectively (P < 0.05). CONCLUSIONS In patients with moderate/severe LAVV regurgitation or severe annular dilation, additional band implantation significantly reduces the incidence of recurrent regurgitation and improves long-term outcomes.

Abstract
ObjectivesInfants with symptomatic partial and transitional atrioventricular septal defect undergoing early surgical repair are thought to be at greater risk. However, the outcome and risk profile of this cohort of patients are poorly defined. The aim of this study was to investigate the outcome of symptomatic infants undergoing early repair and to identify risk factors which may predict mortality and reoperation.MethodsThis multicentre study recruited 51 patients (24 female) in three tertiary centres between 2000 and 2015. The inclusion criteria were as follows: (1) partial and transitional atrioventricular septal defect, (2) heart failure unresponsive to treatment, (3) biventricular repair during the first year of life.ResultsMedian age at definitive surgery was 179 (range 0–357) days. Sixteen patients (31%) had unfavourable anatomy of the left atrioventricular valve: dysplastic (n=7), double orifice (n=3), severely deficient valve leaflets (n=1), hypoplastic left atrioventricular orifice and/or mural leaflet (n=3), short/poorly defined chords (n=2). There were three inhospital deaths (5.9%) after primary repair. Eleven patients (22%) were reoperated at a median interval of 40 days (4 days to 5.1 years) for severe left atrioventricular valve regurgitation and/or stenosis. One patient required mechanical replacement of the left atrioventricular valve. After median follow-up of 3.8 years (0.1–11.4 years), all patients were in New York Heart Association (NYHA) class I. In multivariable analysis, unfavourable anatomy of the left atrioventricular valve was the only risk factor associated with left atrioventricular valve reoperation.ConclusionsAlthough surgical repair is successful in the majority of the cases, patients with partial and transitional atrioventricular septal defect undergoing surgical repair during infancy experience significant morbidity and mortality. The reoperation rate is high with unfavourable left atrioventricular valve anatomy.

Abstract
Long-term survival rate of patients operated for partial atrioventricular (AV) canal is lower than that of the general population, and late complications are relatively significant: between 10 and 30% of operated patients present with left AV valve regurgitation, and up to 25% have to be reoperated for valve repair or replacement, left ventricular outflow tract obstruction or residual atrial septal defect. Because the left AV valve regurgitation is the most common complication following surgery, technical details in the surgical management of the mitral valve are the most important aspects of this procedure; for example, the decision to close the cleft and to perform an annuloplasty. The presence of mitral valve anomalies in 7-28% of the cases complicates further the surgical management of these valves. This article will describe in detail the operative technique of partial AV canal repair, and review the relevant literature.

Abstract
Partial and intermediate atrioventricular septal defects (p-i AVSDs) constitute approximately 20-40% of all AVSDs. Children with p-i AVSDs are usually asymptomatic and typically undergo surgery at the preschool age or earlier if the signs of heart failure have developed. Surgical treatment for repair of p-i AVSDs has been successful for more than 60 years and is mainly directed towards closing septal defects, and maintaining or creating competent, non-stenotic left and/or right atrioventricular valves. By most measures, the outcomes of surgical management of p-i AVSDs have improved over the last 5 decades. In spite of significantly reduced mortality, the need for reoperation and long-term morbidity remains an issue in some patients from this population. The purpose of this article is to review current options and outcomes concerning the surgical management of the p-AVSD and i-AVSD variants without major associated cardiac malformations.

Abstract
OBJECTIVES Postoperative left atrioventricular valve (LAVV) dysfunction is known to be the principal risk factor influencing outcome after repair of all types of atrioventricular septal defect (AVSD). The purpose of the present study was to identify the risk factors for reoperation and to assess the outcomes after reoperation for LAVV dysfunction. METHODS Records of 412 patients who underwent anatomical repair for different types of AVSD from January 2000 to July 2012 were reviewed. The study group (n = 60) included 13 additional patients for whom repair ± LAVV reoperation was performed in a primary institution. Outcomes, independent risk factors, reoperation and death were analysed. RESULTS There were 7 early, (1.7%) and 1 late death. Forty-seven (11.4%) required 64 reoperations for LAVV dysfunction. The median delay for the first LAVV reoperation was 3.5 months (range: 5 days to 10.0 years). Unbalanced ventricles with small left ventricle [odds ratio (OR) = 4.06, 95% confidence interval (CI): 1.58-10.44, P = 0.004], double-orifice LAVV (OR = 5.04, 95% CI: 1.39-18.27, P = 0.014), prior palliative surgery (OR = 3.5, 95% CI: 1.14-10.8, P = 0.029) and discharge echocardiography documenting LAVV regurgitation grade >2 (OR = 21.96, 95% CI: 8.91-54.09, P < 0.001) were found to be independent risk factors for LAVV reoperation. Twelve-year survival and freedom from LAVV reoperation rates were, respectively, 96.1% (95% CI: 94.1-98.1) and 85.8% (95% CI: 81.3-90.3). Survival was significantly worse in patients who underwent LAVV reoperation (P < 0.001) and in those who underwent valve replacement vs valve repair (P = 0.020). CONCLUSION After AVSD repair, LAVV dysfunction appears to be the principal factor that influences outcome. It can usually be managed by repair. Need for multiple reoperations is not uncommon. Long-term outcome in patients with repaired LAVV is favourable.

Abstract
Aortic regurgitation (AR) has increased in the pediatric population because of the expanded use of new surgical and hemodynamic procedures. Unfortunately, the exact timing for operation in patients with AR is still debated. Conventional echocardiographic parameters, left ventricular (LV) dimensions and the LV ejection fraction, have limitations in predicting early LV dysfunction. Two-dimensional strain imaging, an emerging ultrasound technology, has the potential to better study those patients. The aim of this study was to assess the prognostic value of 2-dimensional longitudinal strain in young patients with congenital isolated moderate to severe AR. Twenty-six young patients with asymptomatic AR (aged 3 to 16 years) were studied. The mean follow-up duration was 2.9 ± 1.2 years (range 0.5 to 6). Baseline LV function by speckle-tracking and conventional echocardiography in patients with stable disease was compared with that in patients with progressive AR (defined as development of symptoms, increase in LV volume ≥15%, or decrease in the LV ejection fraction ≤10% during follow-up). LV ejection fractions were similar between groups. The jet area/LV outflow tract area ratio was significantly increased in patients with AR with progressive disease (31.2 ± 5.6% vs 39.2 ± 3.8%, p <0.001). The peak transmitral early velocity/early diastolic mitral annular velocity ratio was significantly increased in patients with progressive AR (p = 0.001). LV average longitudinal strain was significantly reduced in patients with progressive AR compared to those with stable AR (-17.8 ± 3.9% vs -22.7 ± 2.7%, p = 0.001). On multivariate analysis, the only significant risk factor for progressive AR was average LV longitudinal strain (p = 0.04, cut-off value >-19.5%, sensitivity 77.8%, specificity 94.1%, area under the curve 0.889). In conclusion, 2-dimensional strain imaging can discriminate young asymptomatic patients with progressive AR. This could allow young patients with AR to have a better definition of surgical timing before the occurrence of irreversible myocardial damage.

Abstract
The most common cause of reoperation following repair of atrioventricular septal defect (AVSD) is left atrioventricular valve regurgitation. However, reoperation for subaortic obstruction is required in some, especially after initial repair of partial AVSD. Etiology of reoperation and late outcome were evaluated. Between 1962 and 2007, 146 patients (59 male) underwent reoperation at the authors' institution after prior repair of partial (n = 96) and complete (n = 50) AVSD. Median age at reoperation after repair of partial AVSD was 26 years (range, 10 months to 71 years) and 4.5 years (range, 53 days to 38 years) after repair of complete AVSD. The 3 most common indications for reoperation included left atrioventricular (AV) valve regurgitation in 105 patients, subaortic stenosis in 29, and right AV valve regurgitation in 21. The most common procedures performed included left AV valve repair in 59 (40%) patients, left AV valve replacement in 56 (38%), subaortic fibrous resection/myectomy in 24 (16%), and right AV valve surgery in 19 (13%). Freedom from subsequent reoperation at 10 years was 48% after initial repair of complete AVSD and 84% after initial repair of partial AVSD. During late follow-up, 10-year actuarial survival was 91% and 77% after initial repair of complete and partial AVSD, respectively. The most common indication for reoperation after initial repair of partial or complete AVSD is left AV valve pathology; left ventricular outflow tract obstruction was more common in partial AVSD. Although freedom from subsequent reoperations is higher after initial repair of partial AVSD, these patients have reduced long-term survival when compared with complete AVSD.

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
Between January 1991 and December 2006, 56 patients having a partial atrioventricular septal defect (AVSD) were operated. The purpose of this retrospective study is to analyze the immediate and long-term results of the surgery by granting of the importance to two main problems which are the disturbances of the rhythm and the conduction and the residual mitral regurgitation (MR). The mean age of our patients is of 10 and a half years with a net feminine ascendancy. Ninety-three percent of the patients were in regular sinus rhythm. No case of complete atrioventricular block (AVB) was noted. The MR was of grade I in 28.5% of the cases, grade II in 60% of the cases and grade III and IV in 7.5% of the cases. The MR was mild in 4% of the cases. The correction was made under cardiopulmonary bypass (CPB) and consisted of a suture of the mitral cleft in most of the cases with lock of the ostium primum by a patch of pericardium. The perioperative mortality was 1,8% of the cases. The disturbances of the rhythm and the conduction were noted in 34% of the cases. All the patients were controlled with a mean follow-up of six years and seven months. The secondary mortality was nil. The MR, at mid-term follow-up, was mild in 78% of the cases. The partial AVSD is a congenital heart disease, the spontaneous evolution of which can be burdened by complications, notably the disturbances of the rhythm and the conduction, as well as the heart failure. This justifies a premature surgical repair.

Abstract
BACKGROUND This investigation was designed to determine long-term survival, reoperation rates, and functional status after surgical repair of partial atrioventricular septal defect (PAVSD). METHODS This population-based cohort study with cumulative, prospective follow-up by questionnaire and medical record review included all patients aged younger than 19 years old in the state of Oregon who underwent surgical repair of a PAVSD from 1958 to 2000. The incidence of early death, late death, and reoperation for left atrioventricular valve pathology were determined. Patient-reported health status as measured by the Medical Outcomes Study Short Form 12 (SF-12) was obtained for patients without Down syndrome when they were aged older than 15 years. RESULTS Repair of PAVSD was done in 133 patients. Median follow-up was 8.7 years for a total of 1541 person-years. Mean age at the initial operation was 5.2 +/- 5.1 years (median, 3.4 years). Mean weight was 19.2 +/- 16.0 kg (median, 13.2 kg). Survival was 95% at 30 days, 87% at 10 years, and 78% at 30 years. Reoperation for left atrioventricular valve pathology was done 15 patients (11.3%). Lower weight, absence of Down syndrome, and lack of mitral valve cleft repair were significantly associated with undergoing reoperation. Patient-reported health status was obtained in 35 patients. For this group, the mean SF-12 summary scores for the physical component (52.8 +/- 9.0) and the mean mental component (50.3 +/- 11.0) were not significantly different from age-adjusted norms. CONCLUSIONS The survival rate for this simple cardiac defect is lower than the general population. In addition, the reoperation rate is significant. Despite this, in general, patients without Down syndrome can expect normal functional health status.

Abstract
BACKGROUND Left-sided atrioventricular valve regurgitation is the main indication for reoperation in patients after repair of both partial and complete atrioventricular septal defect. Until now, the timing for reoperation is difficult. We sought to determine the outcome of severe residual left-sided atrioventricular valve regurgitation, either medically treated or reoperation. In this regard risk factors were determined for severe residual left-sided atrioventricular valve regurgitation and reoperation, and the most appropriate strategy for patients with postoperative severe left-sided atrioventricular valve regurgitation was identified. METHODS Retrospective review of clinical, operative, and echocardiographic data was performed. From 1990 until 2001 164 patients underwent correction of their atrioventricular septal defect. RESULTS Five patients died in the immediate postoperative period, and 2 patients were lost to follow-up. During follow-up (median, 66 months; range, 9 months to 12 years), 30 patients (19%) had severe left-sided atrioventricular valve regurgitation. Sixteen patients had severe left-sided atrioventricular valve regurgitation in the immediate postoperative period; 4 of them showed spontaneous regression to near-normal valve function during follow-up. Fourteen patients exhibited left-sided atrioventricular valve regurgitation during follow-up; 8 of them remained stable with medication only. Fifteen of the 30 patients with severe left-sided atrioventricular valve regurgitation underwent reoperation. A significant risk factor for the development of severe left-sided atrioventricular valve regurgitation and reoperation was the presence of preoperative severe left-sided atrioventricular valve regurgitation. CONCLUSIONS Severe left-sided atrioventricular valve regurgitation develops in a significant number of patients after correction of atrioventricular septal defect, and preoperative severe left-sided atrioventricular valve regurgitation is an important risk factor. Although reoperation usually results in good valve function, spontaneous regression after the immediate postoperative period is possible and should be given a fair chance.

Abstract
BACKGROUND Aortic valve regurgitation (AR) in the pediatric population has increased in recent years because of the expanded use of new surgical and hemodynamic procedures. Unlike adult patients, few predictors for the need of operation have been proposed in young asymptomatic or mildly symptomatic patients with AR. METHODS To unmask early abnormalities of left ventricular (LV) function, 59 participants were enrolled: 14 asymptomatic patients (mean age 18 years) with congenital isolated severe AR and normal LV function (LV ejection fraction > 50%); and 45 healthy control subjects with comparable age and body surface area. All the studied population underwent standard echocardiographic examination, integrated backscatter, and strain rate imaging study. RESULTS Conventional echocardiographic indices of global LV systolic performance for patients with AR were similar to that of control subjects. Compared with control subjects, integrated backscatter analysis demonstrated a significant reduction in cyclic variation in both septal and posterior walls ( P < .05). LV radial and longitudinal deformation properties for patients with AR were significantly reduced ( P < .05) as assessed by peak systolic strain rate. CONCLUSION Our results demonstrated the ability of integrated backscatter and strain rate imaging to detect early subclinical abnormalities in young patients with severe congenital AR despite the presence of a normal ejection fraction.

Abstract
BACKGROUND The aim of this study was to evaluate the impact of weight less than 5 kg at operation on mortality and morbidity in patients with atrioventricular septal defect (AVSDc) undergoing total correction. METHODS Between January 1990 and December 2002, 190 consecutive patients with AVSDc underwent total biventricular correction. They were divided into two groups: group I (n = 64 patients weighing < 5 kg) and group II (n = 126 patients weighing > 5 kg). Associated major cardiac malformations were found in 49 (25.8%) patients. Associated left atrioventricular valve (LAVV) malformations were found in 35 (18.4%) patients. The mean follow-up time was 4.1 +/- 2.9 years (range 2 months-10.7 years). RESULTS The in-hospital mortality in group I was 7.8% (5 patients) versus 8.7% (11 patients) in group II (p = 0.95). Major associated cardiac malformations (p < 0.001) and pulmonary hypertension (p = 0.006) were found to be strong predictors for poor postoperative survival. At discharge the mean LAVVR grade in group I was 1.45 +/- 1.2 versus 1.2 +/- 1 in group II (p = 0.13). The actuarial overall survival rates at 1, 3, 5, and 7 years were 96.5%, 92.5%, 91.5%, and 89% respectively and the actuarial overall reoperation free survival rates at 1, 3, 5, and 7 years were 95%, 87%, 84%, and 73%. Twenty-three patients underwent reoperation due to severe left atrioventricular valve regurgitation (LAVVR). Strong predictors for overall reoperation free survival were the operation year before 1995 (p < 0.001), postoperative LAVVR greater than or equal to 2 (p = 0.006), major associated cardiac malformations (p = 0.00034), associated LAVV malformations (p = 0.0044), and non or partial LAVV cleft closure (p = 0.012). The actuarial survival rates between patients weighing less than 5 kg versus patients weighing more than 5 kg were similar (p = 0.51); instead the overall reoperation free survival was significantly lower in patients weighing less than 5 kg (p = 0.022) according to the log-rank test. Weight less than 5 kg (p = 0.023, beta = -0.6) was one of the predictors for reoperation due to severe LAVVR in this series. CONCLUSIONS We may conclude that in the current era repair of AVSDc can be carried out successfully in patients less than 5 kg, however, weight less than 5 kg at initial complete repair seems to be a predictor for late reoperation due to LAVVR. Suture separation at the cleft site or between the leaflets of the newly created mitral valve and the patch remain the main causes of postoperative LAVVR in patients weighing less than 5 kg.

Abstract
BACKGROUND Excellent surgical results have been reported for repair of incomplete atrioventricular septal defect; however, left atrioventricular valve regurgitation (ltAVVR) is a major cause of late morbidity. We reviewed our entire experience with incomplete atrioventricular septal defect in order to investigate long-term results of ltAVVR after repair and determine the factors influencing the progression of ltAVVR in late follow-up. METHODS Between 1983 and 2002, 61 patients underwent surgical repair of incomplete atrioventricular septal defect, including 7 patients with intermediate forms. The age of operation ranged from 1 month to 62 years old (median 5.3 years old). Thirteen patients were less than 2 years old, including 7 infants, while there were 15 adult patients. All patients underwent patch closure of the ostium primum defect. Before 1995, the cleft was left open in 7 patients and partial closure of the cleft was done in 41 patients, whereas complete closure of the cleft was performed in 9 patients since 1996. Preoperative and postoperative ltAVVR at hospital discharge and late follow-up were graded 0-IV by echographic evaluation. RESULTS There was 1 early death and 4 late deaths with a 91% 10-year actuarial survival rate. Preoperative ltAVVR grade was I in 25 patients, II in 31 patients, III in 4 patients, and IV in 1 patient. Postoperatively, ltAVVR deteriorated in 3 patients. Left AVVR decreased in 21 patients, whereas in 37 patients it remained the same at hospital discharge. Consequently, ltAVVR remained grade II in 18 patients, grade III in 2, and there was no patient with grade IV. During the long-term follow-up, 24 patients were noted to have increased ltAVVR, including grade III in 8 patients and grade IV in 4. Reoperations for ltAVVR were required in 5 patients (8.3% of hospital survivors); valve replacement in 3 patients and valve repair in 2. Actuarial freedom from reoperation for ltAVVR was 91% at 10 years, whereas actuarial freedom from postoperative ltAVVR grade III or more was 89% at 5 years and 78% at 10 years. Multivariate analysis indicated that postoperative ltAVVR grade II or more at hospital discharge (p = 0.0032, odds ratio = 7.41, 95%CI: 1.95-28.10) was the only independent variable related to late ltAVVR, whereas age at operation, preoperative grade of ltAVVR, and the method of cleft repair were not significant risk factors. CONCLUSIONS Left AVVR is still a significant risk in long-term follow-up. Because the postoperative grade of ltAVVR is the only independent risk factor for late ltAVVR, more efforts should be focused on left atrioventricular valve repair so as to minimize residual regurgitation, even mild regurgitation.

Abstract
OBJECTIVE To report a new minimally invasive and cosmetic approach for partial atrioventricular septal defect (PAVSD) repair. METHODS From November 1997 to January 2000, six patients with a mean age of 19.2 +/- 7.7 years underwent minimal right vertical infra-axillary thoracotomy for PAVSD repair. Left atrioventricular (AV) valve regurgitation was assessed on the beating heart before and after valvuloplasty. Commissuroplasty of the left AV valve and atrial septum repair were done in all patients. RESULTS There were no operative or late mortality, and no morbidity directly related to the thoracotomy approach. The average length of the incision was 8.3 +/- 131 cm. The arrest times averaged 32.8 +/- 8.3 minutes, and the cardiopulmonary bypass times averaged 66.0 +/- 9.0 minutes. One patient had a mild to moderate left AV valve regurgitation postoperatively. All patients were free of symptoms during the follow-up. CONCLUSION The minimal right vertical infra-axillary thoracotomy is a safer, more cosmetic and less invasive approach than median sternotomy for the repair of PAVSD.

Abstract
BACKGROUND Double-orifice left atrioventricular valve (LAVV) is a rare but surgically important anomaly, which is regarded as a risk factor for surgical correction of atrioventricular septal defects (AVSDs). METHODS Of 209 consecutive patients with AVSDs, double-orifice LAVV was identified in 19 patients (9.1%, including 7 infants). Preoperative LAVV function, surgical procedures and results, incidence of postoperative LAVV dysfunction and reoperations were reviewed and compared between patients with this valve malformation (group I, n = 19) and those without it (group II, n = 190). RESULTS There were no operative or late deaths in group I. Preoperative LAVV function was similar in both groups. The cleft was totally closed in 77.2% of group II and 47.1% of group I (p < 0.01). In partial AVSDs, freedom from postoperative LAVV insufficiency was 77.0% in group II versus 30.5% in group I at 5 years (p = 0.009) and freedom from reoperation was 89.9% in group II versus 58.3% in group I at 5 years (p = 0.012); however, there was no difference in complete AVSDs. None of the infants in group I underwent total cleft closure and 4 of them showed more than moderate LAVV insufficiency postoperatively. CONCLUSIONS Double-orifice LAVV is a significant predictor for postoperative LAVV incompetence and reoperation in partial AVSDs, but not in complete AVSDs. Surgical procedures for the cleft should be individualized with careful intraoperative evaluation of the structure and function of this abnormal valve, especially in partial AVSDs and infants.

Abstract
OBJECTIVES Some features of the left atrioventricular valve (large mural leaflet, dystrophic tissue) represent a challenge for repair of atrioventricular septal defects without postoperative regurgitation. A retrospective study was conducted to evaluate the results of surgically creating a double-orifice left atrioventricular valve in such circumstances. Clinical results were analyzed according to valvular and subvalvular left atrioventricular valve measurements in pathologic specimens with atrioventricular septal defects. METHODS Among 157 patients operated on for atrioventricular septal defect since October 1989, 10 patients underwent primary repair (n = 8) or reoperation (n = 2) by this procedure. Median age at repair was 3.3 years (0.1-33 years). Anatomic types were complete (n = 3), intermediate (n = 5), and partial (n = 2). Preoperative moderate to severe left atrioventricular valve regurgitation was present in 6 patients. After the repair (two-patch technique in complete atrioventricular septal defect, cleft closed in each case), these 10 patients were found to have moderate to severe residual regurgitation not amenable to repair by annuloplasty. The top edge of the mural leaflet was anchored to the facing free edge of the cleft. RESULTS No hospital death or morbidity was observed. Left atrioventricular valve regurgitation was absent or trivial (8 patients) and mild (2 patients). Color-coded echocardiography did not show significant left atrioventricular valve stenosis. The mean diastolic pressure gradient across the left atrioventricular valve was 3.2 +/- 1.1 mm Hg (1.4-4.5 mm Hg). At a median follow-up of 72 months (6-91 months), there was 1 late death, unrelated to left atrioventricular valve malfunction, due to pulmonary vascular obstructive disease. Left atrioventricular valve regurgitation did not increase over time, except in 1 patient in whom regurgitation recently progressed from mild to moderate. At rest, the mean diastolic pressure gradient across the left atrioventricular valve was 3.8 +/- 2.9 mm Hg (1.5-11.2 mm Hg). One child had an early moderate stenosis without pulmonary hypertension. Studies on pathologic specimens (n = 34) indicated that long chordal lengths and large mural leaflet size are essential independent anatomic features to assess its feasibility. CONCLUSIONS Surgical creation of a double-orifice left atrioventricular valve is an effective additional procedure for repair of atypical cases of atrioventricular septal defect. The operation may decrease the need for reoperation or left atrioventricular valve replacement.

Abstract
BACKGROUND We describe the long-term outcome of repair of partial atrioventricular septal defect by determining the rates of survival, reoperation, and occurrence of left atrioventricular valve regurgitation, left atrioventricular valve stenosis, left ventricular outflow tract obstruction, and arrhythmia. METHODS We studied 334 patients who underwent repair of partial atrioventricular septal defect before 1995. RESULTS The 30-day and 5-, 10-, 20-, and 40-year survival were 98%, 94%, 93%, 87%, and 76%, respectively. Closure of the left atrioventricular valve cleft (P =. 03) and age less than 20 years at operation (P <.001) were associated with better survival. Reoperation was performed for 38 patients (11%). Repair of residual/recurrent left atrioventricular valve regurgitation or stenosis was the most common reason for reoperation. Left ventricular outflow tract obstruction occurred in 36 patients, and 7 patients underwent reoperation to relieve this obstruction. Supraventricular arrhythmias were observed in 58 patients (16%) after the operation. Supraventricular arrhythmias increased with increasing age at primary operation (P =.001). Complete atrioventricular block occurred in 9 patients (3%). Permanent pacemakers were implanted in 11 patients. CONCLUSIONS Long-term survival after repair of partial atrioventricular septal defect is good. It is important to close the cleft in the left atrioventricular valve. Reoperation for persistent or recurrent left atrioventricular valve malfunction and relief of left ventricular outflow tract obstruction is necessary in approximately 11% of patients.

Abstract
BACKGROUND Presently, surgical correction of partial atrioventricular septal defects is an extremely viable option giving good results. An aggressive approach toward operating on these patients at an early age may be warranted given the otherwise unfavorable natural history. METHODS A retrospective study was done in 38 consecutive patients from 3 to 58 months of age, who underwent correction between 1981 and 1997. Preoperatively, moderate to severe mitral regurgitation was present in 45% of the patients. Congestive cardiac failure was noted in 41% of the cases. Closure of the left atrioventricular valve cleft was performed in 92% of the cases. A need for mitral annuloplasty was felt in 28% of the cases. Majority of the ostium primum defects in our series were closed by a pericardial patch. RESULTS The early, 30 day mortality was 7.9%. A significantly low incidence of late mitral regurgitation (0.9%) was noted on a follow-up extending up to 14 years. There was only one reoperation during late follow-up. On their last follow-up, 87% of the patients are asymptomatic. CONCLUSION An aggressive approach toward operating at an early age on children with this malformation is safe, effective, and yields excellent long term results.

Abstract
BACKGROUND Repair of primum atrial septal defect in children usually is associated with a low operative mortality, except for a subgroup of children with congestive heart failure. To determine the early mortality and incidence of reoperation in children with primum atrial septal defect, we analyzed retrospectively the results of patients who underwent repair of this defect. METHODS Between July 1982 and December 1996, 180 children underwent repair of primum atrial septal defect. The mean age at repair was 4.6 years (median, 3.6 years; range, 1 month to 16.4 years); of the 180 children, 23 were infants less than 1 year of age. Absent or mild symptoms were present in 145 (80%), whereas 34 (20%) of children presented with severe symptoms or congestive heart failure. RESULTS Early mortality occurred in 3 (1.6%); 2 were less than 1 year of age. Follow-up ranged from 2 months to 14.5 years (mean, 6 +/- 4.2 years). Actuarial survival is 98% at 10 years with no late deaths. Age less than 1 year is a predictor of death. During follow-up, 17 (9%) of the 180 patients underwent reoperation, 5 of whom were in the infant group. Five underwent reoperation for subaortic obstruction, and 12 for left atrioventricular valve regurgitation of whom 11 were repaired; and 1 required valve replacement. Age and preoperative moderate-to-severe left atrioventricular valve regurgitation were predictors of reoperation. CONCLUSIONS Results of the repair of primum atrial septal defect during childhood are favorable. Infants have a higher risk for death and reoperation. Left atrioventricular valve insufficiency and subaortic stenosis are important late complications and can be repaired safely at reoperation.
