[External conduit repair with "valved pericardial roll"].
External conduit repair was performed in 20 patients with "valved pericardial roll (VPR)" made of own pericardium (one case) or porcine pericardium (19 cases). Intraoperative measurement of peak pressure gradients across the valve ranged from 0 to 8 mmHg (mean 1), and that from the pulmonary ventricle to the pulmonary artery ranged from 0 to 38 mmHg (mean 20). Re-evaluation of 7 patients one year after surgery shows no increase in the pressure gradient except the first case, in which VPR was made of own pericardium. In pulsed Doppler echocardiographic study, no regurgitation was found in 4 patients, mild in 6, moderate in 4, severe in 1. VPR is functioning well with longest follow up at 16 months.
