Background

Percutaneous mitral valve repair with mitral clip is an established treatment for patients with severe mitral regurgitation who are prohibitive or high-risk for surgery. Transesophageal echocardiogram (TEE) plays an integral role in the planning of a successful procedure. Left atrial appendage (LAA) velocity is a marker of LAA function with low velocity associated with elevated risk of stroke. However, there are no data about the impact of MitraClip procedure on the LAA function and velocity. We sought to assess the utility of post mitral clip implantation LAA velocity as assessed by intra-procedural TEE in patients with and without atrial fibrillation (AF).

Methods

We evaluated a total of 71 patients with severe mitral regurgitation (MR) who were poor surgical candidates for mitral valve surgery and thus underwent mitral clip procedure between July 2015 to October 2017 after patients with missing data were …
