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 substitute, and cost effective.
