We prospectively assessed whether weight loss following laparoscopic sleeve gastrectomy (LSG) leads to a significant reduction in the epicardial (EFT) and correlation between decline with other clinical parameters.Methods A prospective analysis 98 cases that were scheduled undergo LSG followed up for 12 months was conducted. EFT using two-dimensional (2 D) echocardiography.Results total 70 controls...
