Current surgical management of restrictive ischaemic mitral regurgitation (IMR) includes mitral valve annuloplasty (MVA) using an undersized ring when the mechanism is secondary to leaflet restriction. In our experience, MVA alone is inadequate to eliminate mitral incompetence in these patients. We report the 'Down-Under Repair' as an adjunctive concept for the treatment of a subset of patients with restrictive IMR and associated inferobasal left ventricular aneurysm. The 'Down-Under Repair' reduces mitral leaflet restriction by approximating the origin of the posterior papillary muscle towards the mitral annulus. Midterm results demonstrated sustained valvular competence and symptomatic improvement.

D008875 Middle Aged An adult aged 45 - 64 years. Middle Age
D008944 Mitral Valve Insufficiency Backflow of blood from the LEFT VENTRICLE into the LEFT ATRIUM due to imperfect closure of the MITRAL VALVE. This can lead to mitral valve regurgitation.

D000368 Aged A person 65 years of age or older. For a person older than 79 years, AGED, 80 AND OVER is available. Elderly
D012189 Retrospective Studies Studies used to test etiologic hypotheses in which inferences about an exposure to putative causal factors are derived from data relating to characteristics of persons under study or to events or experiences in their past. The essential feature is that some of the persons under study have the disease or outcome of interest and their characteristics are compared with those of unaffected persons.

D017202 Myocardial Ischemia A disorder of cardiac function caused by insufficient blood flow to the muscle tissue of the heart. The decreased blood flow may be due to narrowing of the coronary arteries (CORONARY ARTERY DISEASE), to obstruction by a thrombus (CORONARY THROMBOSIS), or less commonly, to diffuse narrowing of arterioles and other small vessels within the heart. Severe interruption of the blood supply to the myocardial tissue may result in necrosis of cardiac muscle (MYOCARDIAL INFARCTION).

D058386 Mitral Valve Annuloplasty A type of heart valve surgery that involves the repair, replacement, or reconstruction of the annulus of the MITRAL VALVE. It includes shortening the circumference of the annulus to improve valve closing capacity and reinforcing the annulus as a step in more complex valve repairs.
