ABSTRACT
This study reviewed early clinical outcomes of right ventricular outflow tract reconstruction with Contegra® valved conduits in pediatric patients. Between April 2013 and July 2014, thirteen pediatric patients underwent right ventricular outflow tract reconstruction with Contegra valved conduits. The size of the implanted conduits were 12 mm in 5 patients, 14 mm in 3, 16 mm in 3, and then 2 patients were implanted with bicuspidized conduits for downsizing the conduit to 9 and 10 mm in each. Follow-ups were completed in all patients. One conduit was explanted 7 days after a neonatal biventricular repair for Ebstein's anomaly and pulmonary atresia, timed to be at the point of conversion to a single ventricular palliation. Among the 5 patients who developed significant pulmonary insufficiency and/or conduit stenosis, 3 patients exhibited persistent pulmonary hypertension. Both the bicuspidized conduits resulted in early pulmonary insufficiency. One patient implanted with a ring-supported conduit developed coronary artery stenosis, caused by suppression between the ring of the implanted conduit and the annulus of the mechanical vale. Although the small caliber Contegra valved conduit might be an alternative to RVOT reconstruction, the indication should be carefully considered. More than mild pulmonary hypertension, and low body weight at operation of less than 3.0 kg caused early conduit dysfunction.
