Flap Valve Double Patch Closure of Ventricular Septal Defects in Children With Increased Pulmonary Vascular Resistance

BackgroundClosure of a large ventricular septal defect (VSD) in children with elevated pulmonary vascular resistance (PVR) is associated with significant morbidity and mortality. Sophisticated medications and circulatory assist devices may not be available to assist in the care of children with elevated PVR undergoing VSD closure. We designed a fenestrated flap valve double VSD patch to decrease the morbidity and mortality associated with the...
