Predictors of mortality and morbidity in total anomalous pulmonary venous connection with biventricular physiology: A 10-year Indian single centre experience of 492 patients

Background : Surgical correction of total anomalous pulmonary venous connection (TAPVC) remains associated with significant mortality despite advances in intra-operative and postoperative management. We retrospectively analyzed 492 consecutive TAPVC patients with biventricular physiology, who were operated at our centre, with regard to predictors of mortality, morbidity, and intermediate-term outcomes. Materials and Methods : A total of 492 TAPVC patients with biventricular physiology were operated at our centre from August 2009 to November 2019. Their medical records were reviewed and were followed up during March-April 2020 for any symptoms of cardiac disease. Results : Of 492, 302 (61.38%) were healthy at follow-up, 29 (5.89%) had postoperative mortality, 23 (4.67%) had mortality during the follow-up period, and 138 (28.05%) were lost to follow up. Age
