Objective To summarize the experience of surgical correction of complete atrioventricular septal defect associated with tetralogy of Fallot(CAVSD-TOF). Methods Twelve patients aged 6-16(11.1±2.8) years underwent correction of CAVSD-TOF. The atrioventricular septal defect was closed through a right atriotomy and longitudinal right ventriculotomy in each case. The three-patch technique was used for the first 7 cases and two-patch technique for the later 5 cases. The commissure between the superior and inferior bridging leaflets of the left portion of the common atrioventricular valve was closed in each patient. Right ventricular outflow tract obstruction was relieved by a transannular patch. Results There were 4 deaths in the early postoperative period, 3 deaths in the first 7 cases compared to 1 death in the later 5 cases. The causes of death included severe low cardiac output syndrome(3 cases) and perfusion pulmonary edema(1 case). Six survivors were followed up from 3 months to 13.5 years. Heart function (NYHA) was class I or Ⅱ in all cases. Conclusion CAVSD-TOF can be corrected by using the two-patch technique and closure of atrioventricular septal defect through a combined approach through right atriotomy and right ventriculotomy. Routine closure of the commissure of the left portion of the atrioventricular valve achieves a low incidence of regurgitation.
Anomalous left coronary artery from pulmonary artery (ALCAPA) is a rare congenital heart disease which can induce heart failure in the early period and finally results in death. Surgery is the only way to correct the malformation. Surgical advances and heart assist devices such as extracorporeal membrane oxygenation (ECMO) widespreadly used recently achieve good clinical outcome. However, there exists a dispute about the indications and pattern of operation. The outcome of long-term follow-up is not good. This article reviewed the researches about ALCAPA in terms of operative pattern, the operative pattern and long-term complications.
ObjectiveTo sum up the experience of the primary modified single-patch (MSP) technique applied in our hospital for children with complete atrioventricular septal defect (CAVSD).MethodsThe clinical data of 141 children who underwent primary MSP technique for CAVSD between June 2009 and December 2017 were retrospectively analyzed, including 62 males and 79 females with a median age of 6 (3, 11) months and a median weight of 5.8 (4.5, 7.0) kg. According to Rastelli classification, there were 116 patients in type A, 14 in type B and 11 in type C. Among them, 15 patients were diagnosed with Down’s syndrome. Cardiopulmonary bypass time, aortic cross clamp time, atrioventricular valve regurgitation and other clinical data were recorded during and after operation. ResultsPostoperatively, 17 patients suffered from severe left atrioventricular valve regurgitation (LAVVR) and 6 patients severe right atrioventricular valve regurgitation (RAVVR). In the follow-up period, 5 patients suffered from severe LAVVR and 1 patient severe RAVVR. Left ventricular outflow tract obstruction (LVOTO) appeared in 1 patient during follow-up period and none at the end of follow-up. There were 5 early deaths and 2 late deaths. Twelve patients underwent reoperation with a median interval time of 268 (8, 1 270) days.ConclusionMSP technique is a wise surgical strategy for CAVSD children with good outcomes, improved postoperative mortality and decreased atrioventricular valve regurgitation.
