Abstract
Background: Rheumatic heart disease is the major indication for valve surgery in India. Majority of these patients belong to the low socio-economic groups, long term clinical results with TTK-Sree Chitra valve being presented herewith as an affordable option. Method: Data was evaluated retrospectively to determine long term clinical outcome of 178 TTK-Sree Chitra valve implanted at out institution from January, 1993 through December, 2003. Mitral (n=78), Aortic (n=40) and Double valve replacement (n=30) were performed. Follow up was sought five times in this period. Total follow up was 448±2.8 patient years. Follow up was 94% complete. Results: Early mortality was 2.02% ( 3 patients). Eight (5.4%) late deaths, of 13 total deaths, were due to valve related events (5.41%). Structural deterioration, non structural dysfunction, stuck valve and prosthetic valve endocarditis were not observed. Actuarial freedom from reoperation at 10 years was 100% for valves at both positions. Actuarial survival rate at 10 years was 89.87±7.2%. Conclusions: Overall TTK-Sree Chitra valve is an excellent substitue, and cost effective. (Ind J Thorac Cardiovasc Surg, 2005; 21: 15–17)
