The effect of bariatric surgery on echocardiographic indices: a review of the literature

Abstract

Obesity is the new epidemic and is associated with an increased risk of diastolic and systolic heart failure. Effective treatment options with drastic results such as bariatric surgery have raised interest in the possible reversal of some of the cardiovascular sequelae. Many studies have assessed individually the effect of weight loss on specific echocardiographic indices, mostly employing nonhomogeneous groups. The purpose of this narrative review is to summarise the effect of bariatric surgery on echocardiographic indices of biventricular function and to help in the understanding of the expected echocardiographic changes in bariatric patients after weight-loss surgery.

Keywords: Bariatric; bariatric surgery; echocardiography; imaging; obesity; surgery.
