Majority of patients who needed surgery after failed TEER required mitral valve replacement A new study, presented today at the AATS 101st Annual Meeting, and simultaneously published in the Journal of the American College of Cardiology, finds that patients suffering from severe mitral regurgitation should be carefully screened and counselled before undergoing transcatheter edge-to-edge mitral repair (TEER). Data showed that up to 95 percent of patients who needed surgery after failed TEER could not have their valves repaired, and needed mitral valve replacement to resolve the issue. The findings highlight the need to select patients carefully for TEER.

However, TEER is not currently recommended for younger patients who benefit more from a surgical repair long-term. This caution is supported by this study of 463 patients which provides the first national data on surgical outcomes when TEER fails. The surgical repair rate after failed TEER was only 4.8 percent overall, and 6.8 percent in degenerative disease.
