Abstract 113: Mitral Leaflet Clip Procedure Outcomes: Analysis from the National Cardiovascular Data Registry

Introduction: Mitral regurgitation is one of the most common valvular diseases worldwide. Treatment for severe mitral regurgitation (MR) commonly involves surgical replacement of the mitral valve, but for those who are poor surgical candidates, another option has become mitral valve repair with a mitral leaflet clip procedure (MLCP). In this study, we conducted a descriptive analysis for all patients who underwent MLCP in the United States to investigate preoperative, intraoperative, and postoperative characteristics, techniques, complications, and clinical outcomes. Methods: The National Cardiovascular Data Registry (NCDR) was used to summarize the baseline demographics and procedural quality measures of all patients who underwent MLCP between 2014 and 2017. The change in the demographics, mortality, complications, and clinical outcomes were summarized and visualized in graphs. Results: The number of subjects who underwent mitral valve repair increased from 1,023 subjects in 2014 to 5,075 in 2017. The ov...
