Mid-term results after correction of type I and type II persistent truncus arteriosus in older patients

Abstract Objective: This study aims to analyze long‐term results after correction of type I and type II truncus arteriosus in older patients operated in one institution over five years. Methods: Between 2006 and 2010, 12 patients, median age 4 years, underwent repair of truncus arteriosus. Repair with reconstruction of the right ventricular to pulmonary artery continuity was performed using a valved conduit in 12 patients. Results: There was no early mortality. All patients are alive with their original conduit 0.6 to 5 years after correction. No patients required reoperations for conduit dysfunction. Recent clinical examination was undertaken in all patients and they are in good condition. Conclusions: Though mean age at operation was higher in this study than published results, the operation should be performed if the pulmonary vascular resistance is under 8 units.m² before operation .
