SIMULATED DEPLOYMENT OF PERCUTANEOUS TRANSVENOUS MITRAL ANNULOPLASTY DEVICE INTO HUMAN CORONARY SINUS VESSEL

摘要

Functional mitral regurgitation (MR) is the consequence of left ventricular dysfunction occurring after ischemic heart disease and often has poor prognosis. Surgical repair and replacement of the mitral valve are currently being used to treat severe functional MR However, the technique carries high mortality rate [1] and is not suitable for patients with comorbidities and advanced age [2]. Recently, a new non-surgical intervention, percutaneous transvenous mitral annuloplasty (PTMA), is emerging as an attractive endovascular alternative that is less invasive, less recovery time, and cost effective.
