- W4366742689 abstract "Abstract Background Left ventricular assist devices (LVADs) represent an important therapeutic option for patients progressing to end‐stage heart failure. LVAD has previously been shown to have a promising role in improving mitral regurgitation (MR). Nevertheless, the prognostic value of preoperative uncorrected MR in this population remains unclear. Methods A systematic database search with meta‐analysis was conducted of comparative original articles of patients with preoperative mild MR (Grade 0–I) versus moderate–severe MR (Grade II–III) undergoing LVAD implantation, in EMBASE, MEDLINE, Cochrane database, and Google Scholar, from inception to June 2022. Primary outcomes were overall and operative mortality. Secondary outcomes were neurological dysfunction, gastrointestinal bleeding, right heart failure, LVAD thrombosis, and driveline infection. Results Our search yielded 2228 relevant studies. A total of 19 studies met the inclusion criteria with a total of 11 873 patients. LVAD caused a statistically significant decrease of 35.9% in the number of patients with moderate–severe MR (grade II–III) postoperatively. No significant difference was observed in terms of overall mortality, operative mortality, GI bleeding, LVAD thrombosis, and driveline infection rates between mild and moderate–severe MR. An increased rate of right heart failure was seen among patients with moderate–severe MR, while lower rates of neurological events were also observed. Conclusion LVAD improves the haemodynamics of the left ventricle, to promote resolution of MR. Nevertheless, the severity of preoperative mitral regurgitation in patients undergoing LVAD deployment does not seem to affect mortality." @default.
