Abstract:
Pulmonic valve reconstruction is required for various congenital heart diseases and in concert with aortic valve autograft replacement (ie, the Ross procedure). Current techniques using homografts and autografts are often associated with significant morbidity and mortality, and are technically challenging. Furthermore, the long-term durability of these repairs has been questioned, leading to more frequent use of synthetic valved conduits. We report a case of pulmonary valve replacement and right ventricular outflow tract reconstruction using a stentless bioprosthetic aortic valve and polyester graft as a novel approach after radical pulmonary artery sarcoma resection.
