Abstract:
Eleven cases underwent tricuspid valve replacement with bioprosthetic heart valve between 1981 and 1990. Mean age was 51±12 years old and mean follow up period was 40±40 months. Mitral valve replacement in ten cases and aortic valve replacement in one underwent simultaneously. Warfarin and dipyridamole were prescribed for post-operative anti-coagulant therapy. Post-operative early death within 30 days was seen in two cases and late death was in two cases. Five years survival rate including early death was 70±14% and nine years survival rate was 54±18%. All seven cases excluding demised cases were III°or IV°in NYHA classification preoperatively but six were I°or II°at postoperative period. Preoperative functional status of all fatal cases were IV°. Cardio-thoracic ratio was 76.2±12.8% pre-operatively, 67.7±9.0 one year after operation, 66.3±7.8% three years after operation and 68.9±9.3 five years after operation. In conclusion post-operative cardiac function ameliorated, but could not return to fairly satisfactory state.
