May 05, 2021 When surgery is needed to correct residual or recurrent mitral regurgitation (MR) after transcatheter edge-to-edge repair (TEER), chances are that the patient will need to have the valve replaced rather than repaired, shows a study using the Society of Thoracic Surgeons (STS) Adult Cardiac Surgery Database. Of patients who had mitral surgery after TEER—nearly all of which would have been done with the MitraClip (Abbott) during the study period—only 4.8% underwent surgical repair rather than replacement, Joanna Chikwe, MD (Cedars-Sinai Medical Center, Los Angeles, CA), reported during the virtual American Association for Thoracic Surgery 2021 meeting over the weekend.
