Intrepid is a 43-, 46-, and 50-mm nitinol self-expanding valve with bovine pericardial leaflets that is placed using a transapical delivery system with a 35-Fr access.

This pilot study enrolled 50 patients with severe mitral regurgitation who were symptomatic and at a high surgical risk, or in whom surgery was contraindicated.

The rate of implantation success was 98%; the rate of 30-day mortality was 14% and 1-year survival was 77%. In patients who survived 1 year, there was no device dysfunction, hemolysis, thrombosis, or residual mitral regurgitation. After a 1-year follow-up, 79% of all survivors presented a New York Heart Association (NYHA) functional class I-II.

Conclusion

Treatment with the Intrepid device was feasible and able to correct mitral regurgitation in patients at high or extreme surgical risk.
