Objective To summarize the surgical experience of supracardiac total anomalous pulmonary venous connection(S-TAPVC) and study the surgical technique and outcomes for S -TAPVC. Methods Eightysix patients with S-TAPVC underwent the surgical repair from May 1985 to December 2007. There were 49 males and 37 females. The patients aged from 7 months to 35 years (mean 9.6 years) and weighed from 4.9 kg to 68.0 kg (mean 23.8 kg). The patients were divided into three groups by the approach for the anastomosis. There were 20 patients in groupⅠthrough the right atrium incision, 49 patients in group Ⅱ through the right and left atrium incisions and 17 patients in group Ⅲ through the top of the left atrium incision. The interrupt continuous anastomosis between the common pulmonary venous and the left atrium was used in all patients. The enlarged atrial septal defect(ASD) was repaired with autopericardium. The vertical vein was ligated if the postoperative left atrial pressure was less than 15 mm Hg. But the vertical vein was opened or just partialy ligated if the postoperative left atrial pressure was more than 15 mm Hg. Results There was no early operative death. The postoperative left atrial pressure in three groups were 9.3±3.2 mm Hg, 9.9±2.9 mm Hg and 11.6±3.8 mm Hg, respectively. The cases with open or just partly ligated vertical vein in three groups were 0 case （0%）, 7 cases (14.3%) and 2 cases (11.8%), respectively. The cases of arrhythmia in three groups were 5 cases （25.0％）, 15 cases （30.6%）and 1 case （5.9%）. The severely low cardiac output syndrome occurred in 2 patients and reoperation for bleeding in 2 patients. The morbidity of arrhythmia in group Ⅲ was less than in group Ⅱ（P=0.042）. Conclusion The outcome of surgical repair for S -TAPVC is satisfactory. The anastomosis through the top of the left atrium incision has low occurrence of arrhythmia. The anastomosis through the right and left atrium incision is easy to expose and to perform surgery, especial for old children and adult patients.
Abstract: Objective To evaluate the outcome of reconstruction of right ventricular outlet tract (RVOT) with 0.1 mm Gore-Tex monocusp valve for short and middle term. Methods Between June 2002 to July 2006, 48 patients underwent reconstruction of RVOT with Gore-Tex monocusp valve to correct cardiac anomalies, including 33 patients with tetralogy of Fallot (TOF) and pulmonary stenosis, 8 patients with TOF and pulmonary atresia, 3 patients with TOF and absent pulmonary valve, 2 patients with double outlet of right ventricle and pulmonary stenosis, 1 patient with truncus arterious and 1 patient with complete transposition of great artery, ventricular septal defect and pulmonary stenosis. Results There was no operative death. The postoperative blood oxygen saturation was up to 1.00. The ratioes of right ventricular systolic pressure and left ventricular systolic pressure were between 0.22 to 0.65.The gradient between right ventricle and left or right pulmonary artery was less than 10 mmHg. All patients were followed up including echocardiography ranged from 3 to 48 months. There were no late death and complication. Trivial and mild pulmonary insufficiency was detected in 18 patients and valvular motion remained competent in 40 patients. Conclusion The results suggest that the reconstruction of RVOT with Gore-Tex monocusp valve can achieve excellent outcome for short and middle term.
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.
Objective To report the surgical treatment for double outlet of ventricle with atrioventricular discordance. Methods 11 patients aged from 3 to 25 years underwent surgical treatment for double outlet of ventricle with atrioventricular discordance. 10 of them were double outlet right ventricle and the other one was double outlet left ventricle. The surgical treatment included biventricular repair (n=9) and single ventricular repair (n=2). The biventricular repair was performed by intraventricular patch repair and extracardiac valved conduit or homograft valved conduit. The single ventricular repair included bidirected Glenn operation and total cavopulmonary connect. Results There were two early deaths in biventricular repair and no death in single ventricular repair. The cause of death was severe low cardiac output syndrome. Four survivors in biventricular repair were followed up from 1 to 11.5 years, three of them were in NYHA class Ⅰ or Ⅱ and one in NYHA class Ⅲ. Conclusions Double outlet of ventricle with atrioventricular discordance can be treated by biventricular repair or single ventricular repair according to the development of ventricle and pulmonary arteries. Closure of ventricular septal defect , no obstruction from ventricle to great artery and no harm of conduction system are the keys of conventional management to achieve good results.
From June 2002 to December 2023, there were 5 patients with criss-cross admitted to the General Hospital of the Northern Theater Command, including 3 males and 2 females, aged 18 months to 25 years, and weighing 13-49 kg. There were 5 patients of atrioventricular position, 3 patients of right ventricular loop, 2 patients of left ventricular loop, 3 patients of normal atrioventricular connection, and 2 patients of inconsistent connection. Combined intracardiac malformations: 1 patient of simple ventricular septal defect combined with pulmonary hypertension, 1 patient of corrected transposition of the great arteries combined with ventricular septal defect, atrial septal defect, and pulmonary artery stenosis, 1 patient of corrected transposition of the great arteries combined with ventricular septal defect, atrial septal defect, and left atrioventricular valve insufficiency, and 2 patients of right ventricular double outlet combined with ventricular septal defect and pulmonary artery stenosis. The surgical methods included 2 patients of intracardiac anatomical correction, 1 patient of bidirectional vena cava pulmonary artery anastomosis, and 2 patients of total extracardiac ductal cava pulmonary artery anastomosis. All 5 patients were discharged smoothly.
Abstract： Objective?To analyze the risk factors for early shunt dysfunction after systemic-pulmonary shunt in order to improve early postoperative outcomes. Methods We retrospectively analyzed the clinical records of 189 patients who underwent systemic-pulmonary shunt in General Hospital of Shenyang Military District between February 2002 and December 2010. There were 87 males and 102 females with their age ranging from 3 months to 50（5.3±6.2）years，and body weight ranging from 3 to 56（17.7±11.0）kg. There were 94 patients with tetralogy of Fallot （TOF） and pulmonary artery stenosis，51 patients with pulmonary atresia （PA） and ventricular septal defect，4 patients with PA and intact ventricular septum，10 patients with functional single ventricle （SV） and pulmonary stenosis（PS），6 patients with SV and PA，6 patients with double outlet right ventricle and PS，8 patients with transposition of the great arteries（TGA） and PS，and 10 patients with TGA and PA. The surgical procedures included central aorto-pulmonary shunt （Waterston） in 105 patients, modified Blalock-Taussig shunt in 61 patients and Melbourne shunt in 23 patients. Results Early postoperative death occurred in 13 patients （6.9%）. There were 12 patients （6.3%） with intra-operative severe hypotension or arrhythmia, 10 patients （5.3%） with postoperative severe low cardiac output, and 10 patients （5.3%） with early shunt dysfunction within the first 24 h postoperatively. Univariate analysis identified low body weight （P=0.027）, shunt size with diameter＜4 mm （P=0.025） and severe intra-operative adverse event （hypotension or arrhythmia with P=0.002） were risk factors for early shunt dysfunction. In multivariate analysis, intra-operative adverse event was an independent risk factor for early shunt dysfunction（P=0.017）. Conclusion Early outcomes after systemic-pulmonary shunt can be significantly improved by preventing intra-operative severe hypotension or arrhythmia and choosing shunt size larger than 4 mm，especially for patients with young age, low body weight, and poorly-developed pulmonary artery.
