Two patients who had undergone a Fontan operation presented late with considerable disruption of a sutured pulmonary valve. Both patients had increasing ascites, decreased exercise tolerance, atrial arrhythmias, high right atrial pressure, and a large ratio of pulmonary blood flow to systemic blood flow. At operation, the main pulmonary artery was closed either by suturing the anterior and posterior walls together immediately distal to the pulmonary valve or by reinforcing the resutured pulmonary valve with a polytetrafluoroethylene patch. Both patients had an uneventful postoperative course, with disappearance of the symptoms and return of sinus rhythm. Although it is tempting to simply suture the usually thickened pulmonary valve in the Fontan operation, approximation of the pulmonary artery walls or patch reinforcement is necessary to minimize disruption.
