Reconstructing right ventricular outflow tract with conical pericardial conduit in type III pulmonary atresia with ventricular septal defect

Abstract

Objective To summarize the outcomes of reconstructing right ventricular outflow tract with conical pericardial conduit in type Ⅲ pulmonary atresia with ventricular septal defect(PA/VSD). Methods We retrospectively analyzed the clinical data of 7 patients with type Ⅲ PA/VSD who underwent surgical repair in the Department of Cadiovascular Surgery, Guangdong Cardivascular Institute from January 2012 to August 2014. There were 3 males and 4 females at a median age of2.5 years(range, 1.4 to 10.8 years) and a mean weight of(11.4±3.4) kg. All patients were underwent right ventricular outflow tract reconstruction with conical pericardial conduit. Results The mean bypass time was(132.7±32.5)min, the mean aorta cross-clamping time was(71.9±15.1) min. There was 1 patient with diaphragmatic paralysis and 1 patient with chylothorax, both of whom were underwent surgical intervention. There was 1 patient with postoperative pneumonia. The ventilation time was 17.8-356.9 hours. There was no in-hospital death. The mean ICU stays was 2.8-21.5 days and the mean hospital stays was 13-74 days. All patients were alive and no severe anoxia during follow-up. Conclusion The early outcomes of reconstructing right ventricular outflow tract with conical pericardial conduit in type Ⅲ PA/VSD was good. Preoperative evaluation of the pulmonary development and MAPCAs were helpful for making rational choice.
