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

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.

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.

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.

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.m(2) before operation.
