Abstract:
Objective To analyze risk factors for pulmonary vein obstruction (PVO) after intracardiac total anomalous pulmonary venous connection (TAPVC) repair. Methods A retrospective analysis of clinical data of the patients with intracardiac TAPVC who underwent surgery at our center from April 2009 to April 2019 was conducted. Kaplan-Meier curves were used to assess the risk of postoperative PVO. Logistic regression analysis was used to identify relevant risk factor for postoperative PVO. Results We finally included 169 patients. The median age at surgery was 89.0 (41.5, 195.0) days, and the median weight at surgery was 4.8 (3.8, 6.0) kg. The preoperative PVO rate was 18.3% (31/169). Post-repair PVO occurred in 8.9% (15/169) of the patients. The atresia of common pulmonary and subtype of coronary sinus/right atrium did not significantly affect the risk of PVO (P=0.053, P=0.330). Relevant risk factors included preoperative PVO (P<0.001) and the ratio of left ventricular end-systolic diameter to right ventricular diameter (P=0.025). Conclusion Surgical repair of intracardiac TAPVC has achieved satisfactory results in our center, but the long-term risk of obstruction should not be underestimated. An increased ratio of left ventricular end-systolic diameter to right ventricular diameter and preoperative PVO are associated with post-repair PVO.
