Fourteen cases of isolated TVR (Tricuspid valve replacement) for congenital heart disease were studied. The purpose of this communication is to review the long-term prognosis of isolated TVR for congenital heart disease. Eight were Ebstein's anomaly, 3 were tricuspid regurgitation (TR) after closure of ventricular septal defect (VSD). Three other cases were TR after radical surgery of Tetralogy of Fallot, VSD associated with two chambered right ventricle and VSD with right ventricular infundibular stenosis, respectively. The operative mortality rate was 7.1% and the actuarial survival curves for the 14 patients are shown to be 92.9% for the 1st year, 60.4% as 5 years and 60.4% after 20 years. One patient died on the second day after TVR due to a complete A-V block. The causes of late death included pulmonary embolism, sudden death, cardiac failure and sepsis, respectively. One case of Ebstein's anomaly was performed for the re-TVR 19 years 8 months postoperatively due to a thrombosed valve. One of 5 porcine xenograft valve cases which was replaced 9 years 9 months ago is scheduled to undergo cardiac catheterization because of a systolic murmur and hepatomegaly. The other 7 cases followed up from 1 year 3 months to 18 years 1 month remained in NYHA functional class I in 6 cases and class II in 1 case. Periodic check up of the prosthetic valve by UCG and the monitoring of arrhythmia are essential as well as the application of antiplatelet agents to prevent thrombosis.
