Right ventricular outflow tract (RVOT) reconstruction with a new composite pericardial
monocusp patch incorporating a sinus of Valsalva was performed in 7 patients. There
was one hospital death. Follow-up ranged from 20 to 52 months (mean 25.4 months, cumulatively
206 patient months). Four patients have been recatheterized at an average of 6.5 months
(1 to 12 months) after surgery. The average RVOT gradient was 9 ± 2 mmHg, and mean
right ventricular end-diastolic pressure was 10 ± 5.5 mmHg. All except one have a
competent pulmonary valve with normally functioning monocusp, and no thrombosis, calcification
or aneurysmal dilatation.
