Of these patients, 128 with a common atrioventricular valve were excluded. Thirty-eight patients underwent closure of an atrioventricular valve, and complete follow-up data were available for 36 patients. Twenty-nine patients underwent closure of the tricuspid valve and 7 patients underwent closure of the mitral valve. Seventeen patients underwent valve closure prior to Fontan, 13 patients underwent valve closure concomitant with Fontan and 6 patients underwent valve closure post-Fontan. Valve closure was performed using a patch technique in 29 cases and with direct suture in 7 cases. At the most recent echocardiography, 33 patients had no regurgitation, 2 patients had recurrent mild regurgitation and 1 patient had no echocardiographic follow-up. Six patients required reintervention post-valve closure and 7 patients required permanent pacemaker insertion post-valve closure. Freedom from reintervention at 1, 5 and 18 years post-valve closure was 86% [95% confidence interval (CI) 76\u201398%], 83% (95% CI 72\u201396%) and 83% (95% CI 72\u201396%), respectively.<\/jats:p>\n
