Prediction of spontaneous echo contrast following mitral valve transcatheter edge-to-edge repair.

ABSTRACT:

Background

Although no studies predict thrombotic events after mitral valve transcatheter edge-to-edge repair (MV-TEER), 34% of patients experience worsening spontaneous echocardiographic contrast (SEC) following MV-TEER. We hypothesized that predicting the SEC occurrence or rapid progression after MV-TEER and identifying associated cases would be valuable.

Methods

This retrospective study included 176 consecutive patients who underwent MV-TEER at Hiroshima University Hospital. SEC worsening was assessed using intraoperative transesophageal echocardiography pre- and post-procedure.

Results

The study analyzed 168 patients undergoing MV-TEER (median age 80, 56 % male). Severe mitral regurgitation (MR), secondary MR, and atrial fibrillation were present in 67.5 %, 70.2 %
