ABSTRACT
@#Objective To evaluate the effects of anatomic correction for congenitally corrected transposition of the great arteries (ccTGA) and 10-year follow-up. Methods From January 2008 to December 2018, 48 patients with ccTGA who underwent anatomic correction were reviewed. There were 29 males and 19 females with age of 39.2 (3-91) months. The cohort was divided into two groups: a biventricular anatomic correction group (39 patients) and a 1.5 ventricular anatomic correction group (9 patients). They were followed for in-hospital mortality, late mortality, long-term survival, freedom from reoperation, and heart function. Results There were 3 early deaths and 2 early re-intervention in the biventricular anatomic correction group, but no death and only one re-intervention in the 1.5 ventricular anatomic correction group. Compared with the biventricular anatomic correction group, the operation time, tracheal intubation and ICU time were significantly reduced or shortened in the 1.5 ventricular anatomic correction group (P<0.05). The patients were followed up for 0.5-10.4 years. Four patients were lost. Two patients died in the biventricular anatomic correction group, and two patients received re-intervention. The 1-year, 5-year and 10-year survival rate was 88.2%, 84.0%, and 84.0%, respectively. There was no death or intervention in the 1.5 ventricular anatomic correction group. The quality of life of the other patients in the medium-term follow-up was satisfactory. Only 2 patients were classified as grade Ⅲ in cardiac function, and the other patients were classified as grade Ⅰ-Ⅱ. Conclusion According to the different anatomic characteristics of ccTGA, the individualized strategy of anatomic correction can achieve satisfactory surgical results, and the medium-term quality of life was good. Especially, 1.5 ventricular anatomic correction may obtain better therapeutic effects because of its lower operative mortality and less postoperative complications.
ABSTRACT
@#Pulmonary atresia with intact ventricular septum (PA/IVS) is a rare congenital heart disease with high mortality. Due to the complexity and diversity of pathological anatomy, there is no uniform standard for the optimal surgical scheme of PA/IVS. In order to further standardize the surgical treatment strategy of PA/IVS, this expert consensus will focus on the evaluation of right ventricular anatomy and function, operation timing, operation mode and prognosis of PA/IVS. Through the synthesis of many domestic treatment experience, the Chinese expert consensus on PA/IVS surgical treatment has been finally formed.
ABSTRACT
@#Objective To evaluate the effect of off-pump pulmonary valvulotomy for the patients with pulmonary atresia with intact ventricular septum (PA/IVS). Methods The clinical data of 61 PA/IVS patients who underwent off-pump right ventricular decompression surgery in our hospital from January 2013 to September 2019 were retrospectively analyzed, including 37 males and 24 females, with an average age of 29.7 (2.0-86.0) d and weight of 4.1 (2.5-6.9) kg. Thirty-nine patients received off-pump pulmonary valvulotomy (an open-view valvulotomy group) and 22 patients received balloon valvuloplasty through the right ventricle pulmonary valve (a hybrid therapy group). The postoperative mortality, early re-intervention, and completion of final operation of the two groups were compared. Results There were 2 deaths in the study with a mortality rate of 3.3% (2/61), and the mortality rate of the two groups was not significantly different (2.6% vs.4.5%, P=0.68). The rate of early re-intervention in the two groups was 5.3% and 19.0%, respectively (P=0.09). There was no statistical difference in intubation time (56.0±25.9 h vs. 62.0±28.9 h, P=0.41), ICU retention time (4.7±2.9 d vs. 5.5±2.2 d, P=0.23) and postoperative hospital stay time (3.9±0.9 d vs. 4.3±1.1 d, P=0.38) between the two groups. The follow-up time was 45.3 (4.0-84.0) months. There were 5 patients lost to follow-up. During the follow-up period, in the open-view valvulotomy group, 17 patients did not need further operation, 13 patients completed the final operation. In the hybrid therapy group, 7 patients did not need further operation, 8 patients completed the final operation. Heart function classification of all patients was in New York Heart Association class Ⅰ-Ⅱ. Conclusion Compared with the hybrid therapy, off-pump pulmonary valvulotomy for PA/IVS also has the advantages of simple operation, short operation time and high survival rate, and it may be easier to be promoted in clinical application because of its more economic benefits and relatively lower re-intervention rate.
ABSTRACT
Complex congenital heart disease; right ventricular outflow tract reconstruction; autologous tissue; extracardiac conduit@#Objective To assess the mid- and long-term outcomes of right ventricular outflow tract reconstruction for children with congenital heart disease. Methods We retrospectively analyzed the clinical data of 3 138 children with complex congenital heart disease in right heart system admitted to our hospital from January 2007 to January 2017. There were 1 660 males and 1 478 females. The age at surgery was 9 days to 84 months, and the body weight was 2.2 to 28.6 kg. Pulmonary patch enlargement was performed in 2 335 patients (1 477 patients of valve-sparing repair and 858 patients of transannular repair); autologous tissue (direct anastomosis, left auricle or pericardial conduit) was used to connect with right ventricle in 289 patients; extracardiac conduits were used for reconstruction in 514 patients. Results There were 181 in-hospital deaths with a mortality of 5.8%. The early postoperative causes of death were low cardiac output syndrome (LCOS), severe pulmonary hypertension and right heart failure. Fifteen patients died of cardiac insufficiency or sudden death during follow-up (6–27 months postoperatively). The echocardiography showed 408 patients with right ventricular outflow tract obsturction (RVOTO), 340 patients with pulmonary trunk or branches stenosis, 609 with pulmonary regurgitation (morderate or severe). 12.6% (394/3 138) of patients underwent reintervention or reoperation with 39 deaths. About 92.4% of patients exhibited an improvement of New York Heart Association (NYHA) functional class from Ⅲ or Ⅳ preoperatively to Ⅰ or Ⅱ at follow-up. Conclusion The anatomical structure of right ventricular outflow tract is complicated and various, and each operation method has different strengths and favorable outcomes. The operation should be individually designed according to pathological types, anatomical features, clinical symptoms and operation conditions.
ABSTRACT
@#Objective To explore the surgical management method and outcome of functional univentricular heart with total anomalous pulmonary vein drainage (UVH-TAPVD). Methods We reviewed the surgical procedures and results for 44 UVH-TAPVD patients in our hospital between the year 2010 and 2016. There were 34 males and 10 females. The age of the patients was 312 (77-4 220) d when they accepted the first surgical treatment. Results There were 8 deaths in stage Ⅰ palliation, 1 death in stage Ⅱ palliation and 5 deaths during the follow-up. The overall survival rate was 68.2% (30/44). Glenn operation was undertaken in 34 patients with 5 deaths. Fontan operation was undertaken in 9 patients with 2 deaths. Conclusion Surgical strategies for UVH-TAPVD should be planned according to different anatomical and pathophysiological conditions in different patients. Staged palliations can reduce mortality and morbidity. But pulmonary venous obstruction and heterotaxy syndrome are still risk factors for these patients.
ABSTRACT
@#Objective To explore current results after staged operations in patients with functional single ventricle anomalies and pulmonary hypertension. Methods We retrospectively analyzed the clinical data of 129 patients with functional single ventricle anomalies and pulmonary hypertension undergoing pulmonary artery banding in our hospital between April 2008 and December 2015. There were 81 males and 48 females. There were 71 patients with double outlet of right ventricle, 17 patients with tricuspid atresia, 7 patients with transposition of great arteries, 33 patients with uni-ventricular heart, and one patient with complete atrio-ventricular septal defect. The surgical results, transition to Glenn procedure and subsequent transition to Fontan procedure were analyzed. Results The 129 patients underwent 159 operations of pulmonary artery banding totally. Hospital mortality was 4.7% (6/129). Nine patients were lost to follow-up. Eighty-seven (67.4%) patients underwent the second-stage Glenn procedure, and 43 patients(33.3%) underwent third-stage Fontan procedure. Two patients died after Glenn and 3 patients died after Fontan separately. There were 32 patients who accompanied with coarctation, interruption of aortic arch, heterotaxy, total anomalous pulmonary venous connection or atrio-ventricular valve regurgitation. Fifteen (46.9%) patients succeeded in transition to Glenn, and 6 (18.8%) patients succeeded in transition to Fontan. Fourteen patients developed obstruction of left ventricular outlet tract or bulbo-ventricular foramen. Conclusion Early pulmonary artery banding is an acceptable strategy for patients with single ventricle anomalies and pulmonary hypertension. Outcomes and results of subsequent Glenn and Fontan procedures are generally good. Accompanied complex anomalies are risk factors for lower ratio of transition to Glenn and Fontan procedure.
