Treatment of supracardiac total anomalous pulmonary venous connection in a single center / 中国胸心血管外科临床杂志

ABSTRACT

@#Objective    To analyze the surgical results of patients with supracardiac total anomalous pulmonary venous connection (TAPVC) in a single pediatric cardiac center. Methods    A retrospective study was conducted on 98 pediatric patients with supracardiac TAPVC receiving surgical repair from 2014 to 2019 in our center. There were 64 males and 34 females with a median surgical age of 3.0 (1.5, 7.0) months and a median weight of 5.0 (4.0, 6.0) kg. Twenty-three (23.5%) patients had preoperative pulmonary vein obstruction. Ninety-two (93.9%) patients received conventional surgical repair, while six (6.1%) patients were treated with the sutureless technique. The Cox regression model was used to analyze the data. Results    The median follow-up time was 26.50 (5.75, 44.25) months. There were 9 (9.2%) deaths. Lower weight at the time of repair (P=0.013) and prolonged cardiopulmonary bypass time (P=0.007) were associated with mortality. Postoperative pulmonary vein obstruction was observed in 8 (8.2%) patients. Associated risk factors for postoperative pulmonary vein obstruction included lower weight at the time of repair (P=0.042) and prolonged cardiopulmonary bypass time (P=0.002). Conclusion    Surgical repair of supracardiac TAPVC has achieved satisfactory results in our center. Risk factors such as lower weight at the time of repair and prolonged cardiopulmonary bypass time are associated with a poor prognosis.
