Effect of Longitudinal Strain on Clinical and Echocardiographic Outcomes After Cardiac Surgery for Moderate Ischemic Mitral Regurgitation

Outcomes and risk analysis after tricuspid valve surgery for non-Ebstein 2-ventricle congenital tricuspid valve diseases

“…Similarly, recent large cohort studies on adults with acquired heart disease have reported such an association when MR was greater than moderate. 30,31 The progression of TV annular dilatation and subsequent functional TR are caused by further worsening of pulmonary hypertension, atrial arrhythmias, and right and left ventricle interdependence. 32 Although the mechanism of TR recurrence was not systematically available in our study, we hypothesize that the mechanism by which preoperative MR contributes to TR recurrence in our cohort of patients with congenital heart disease is similar.…”

“…This study included 492 patients, with 59% undergoing CABG, while 41% did not require CABG at the time of mitral valve surgery, and 66% of patients having echocardiographic data analysis at a 2-year follow-up. Only 15% of patients required bypass to the RCA [33]. However, these former reports did not indicate details about the extent of the RCA disease or the location and patency of the bypass to the RCA system.…”

“…Another group has shown progression of functional TR in patients with dilated cardiomyopathy (the majority were ischemic) after repair of functional MR +/− CABG [31,32]. In a recent study that included data from two prospective randomized ischemic MR trials, progression of non-severe TR was found to be infrequent while patients with > moderate TR at 2-year follow-up had significant clinical events [33]. This study included 492 patients, with 59% undergoing CABG, while 41% did not require CABG at the time of mitral valve surgery, and 66% of patients having echocardiographic data analysis at a 2-year follow-up.…”
