Aims Ischaemic mitral regurgitation (IMR) is consequence of left ventricular (LV) remodelling after myocardial infarction. In some cases, the mitral valve enlarges to compensate for LV remodelling and tenting, improving its coaptation; a process termed 'plasticity'. We sought to identify clinical and echocardiographic factors associated with plasticity in patients with chronic inferior myocardial infarction (CII). Methods and results This study included 91 revascularized CII patients and 46 controls. Plasticity and IMR severity were evaluated by 2D transthoracic echocardiography. Compared with controls, CII patients were older (59 vs. 25 years) and mostly men (80% vs. 46%), both P
