Patients with congenital heart defects characterized by a hypoplastic right ventricle (RV) are at high risk for the development of postoperative RV failure. Although the usefulness of a 1-way valved patch1
for biventricular repair of a hypoplastic RV2
has been reported in pediatric patients, little is known about the effects of a 1-way valved patch in adult patients. Here we report biventricular repair in an adult patient by using a 1-way valved patch to reduce the risk of postoperative RV failure.
Clinical Summary
A 60-year-old man weighing 79 kg was given a diagnosis of a secundum atrial septal defect (ASD), severe pulmonary stenosis, and a hypoplastic RV. On admission, his oxygen saturation as measured by means of pulse oximetry was 80% at room air, and erythrocytosis (hematocrit level, 63%) was detected. Transesophageal echocardiography showed a secundum ASD of 15 mm with a right-to-left shunt and a tricuspid valve diameter of 33
