Nationwide Long-term Follow-up of Pulmonary Atresia With Ventricular Septal Defect

Introduction: The naturally poor survival of pulmonary atresia with ventricular septal defect (PA+VSD) has improved due to evolved perioperative and surgical treatment. Studies including PA+VSD patients, both with and without major aortopulmonary collateral arteries (MAPCAs), with extensive follow-up are scarce. This nationwide study aimed to investigate survival and surgical treatment in PA+VSD patients with and without MAPCAs. Methods: Study comprised 109 PA+VSD patients born in Finland between 1970 and 2007. We reviewed retrospectively medical records and operative reports through December 2011, as well as first available angiograms and preoperative angiograms prior to repair attempt. Results: The median follow-up time for the total study population, including also patients who died during the follow-up, was 11.4 years (IQR 0.8 - 21.1). The incidence of PA+VSD, which could be determined reliably from 1995 to 2007, was 6.1 per 100 000 live births. Although the patients with (n = 43) or without MAPCAs (n...
