| pubmed-article:2614108 | pubmed:abstractText | From 1983 to 1985, Fontan type operation were successfully performed on five patients with single ventricle. Marked cyanosis disappeared soon after the surgery, and normal exercise tolerance was obtained in all cases but one in the late postoperative period. Compared to marked improvement in the exercise tolerance test, cardiac output remained subnormal both at rest and during exercise even in the late postoperative period. Several types of asymptomatic arrhythmias were observed during the acute postoperative days, but they were not recognized in the intermediate-term postoperative period. Routine blood chemistry studies showed that hepatic function was within normal limits, but hepatic dysfunction was suggested by Indocyanine Green clearance test. Renal function was well preserved after Fontan type procedure. Though cardiac output is subnormal, Fontan type procedure is a safe and effective operation, and intermediate-term state is satisfactory without any signs of heart failure. | lld:pubmed |
