Dyssynchrony: A different kind of mitral regurgitation

Abstract

The authors present a patient with symptomatic chronic MR in the setting of severe LV dyssynchrony. This is a distinct entity, with a complex pathophysiology and mechanism of MR. This case highlights the need for a comprehensive preoperative analysis of the mechanism of MR in all patients with sympto- matic MR, given its multiple etiologies and distinct therapeutic options. A multidisciplinary approach that includes preoperative strain analysis and clinical consideration of patient candidacy for CRT should preferably be taken prior to surgery in deciding the best therapy in order to ensure the best outcomes.
