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.
