Abstract

Pulmonary valve replacement is becoming the most frequent congenital heart surgery performed on adolescents and young adults. Numerous surgical options are available, including autologous pericardium, mechanical valves, allografts, and bioprosthetic valves. Each option has limitations with durability and freedom from reintervention for stenosis or insufficiency, particularly in the pediatric population. The purpose of this study was to analyze our uniquely designed, expanded polytetrafluoroethylene (ePTFE) valved conduit (VC) for right ventricular outflow tract reconstruction. Beginning in 2012, ePTFE VC were implanted in 26 patients with a median age of 9.8 years (range, 1.0 to 15.9). Bicuspid VC were used in the first 3 patients, and tricuspid VC were used in 23 patients. The ePTFE VC is fashioned from commercially available ePTFE tube graft (16 mm in 1 patient, 20 mm in 7 patients, 24 mm in 18 patients) and 0.1 mm thick ePTFE membrane for the leaflet material. Valve function was assessed by echocardiogram after the implantation. There were no postoperative hospital deaths. Mean follow-up was 2.6 years (range, 4 months to 4.7 years), and there have been no reoperations for the ePTFE VC. There was one reintervention for stenos...Continue Reading

Birth Defects

Birth defects encompass structural and functional alterations that occur during embryonic or fetal development and are present since birth. The cause may be genetic, environmental or unknown and can result in physical and/or mental impairment. Here is the latest research on birth defects.
