Secondary Mitral Regurgitation
New England Journal of Medicine, 2020Whereas primary mitral regurgitation (MR) is due to a structural or degenerative abnormality of the mitral valve (MV) or adjacent structures, secondary or functional MR occurs in the absence of organic MV disease, usually resulting instead from left ventricular (LV) dysfunction.

Ischemic mitral regurgitation is the regurgitation seen with structurally normal valve leaflets that occurs in approximately 20% of patients after myocardial infarction and 56% of patients with congestive heart failure caused by ischemic or nonischemic cardiomyopathy.

The mitral apparatus is a complex structure composed of several components, each of which can be affected by a variety of diseases, resulting in mitral regurgitation. The physiologic consequences of mitral regurgitation include reduced forward stroke volume; increased left atrial volume and pressure; and reduced resistance to left ventricular ejection.

The diagnosis of acute mitral regurgitation (MR) is often missed or delayed because the clinical presentation is substantially different from that in patients with chronic MR. Management of acute MR depends on the specific aetiology of valve dysfunction and there is a lack of consensus on the optimal therapeutic approach in many patients. In particular,

Evaluation of Mitral Regurgitation
Seminars in Cardiothoracic and Vascular Anesthesia, 2006Transesophageal echocardiography (TEE) provides high-resolution images of the mitral valve apparatus, permitting detailed evaluation of its structure and function. Mitral valve evaluation is invaluable during mitral valve repair surgery, providing insight into the mechanism of valve dysfunction and formulation of a plan for repair.

Summary: The occurrence of significant mitral regurgitation without the characteristic auscultatory signs, particularly the holosystolic murmur and the third heart sound, is unusual. It becomes of considerable importance when it occurs in combined lesions of the mitral valve, and more so in those areas where the treatment of mitral stenosis is by ...

Ischemic mitral regurgitation (IMR) is a functional problem, which results from ischemia of the ventricle. Except in the case of ischemic papillary muscle rupture, the mitral apparatus is anatomically normal and the regurgitation is solely caused by abnormal systolic motion of the ventricle, interfering with the normal closure physiology of the valve ...

Mitral Valve Repair for Mitral Regurgitation
Revista Española de Cardiología (English Edition), 2006We analyzed the results of mitral valve repair in 81 consecutive patients with severe mitral regurgitation. Of these patients, 66.6% had myxomatous degeneration, 11% ischemic disease, 8% chordal rupture, 5% congenital disease, and 3.7% endocarditis. Repair could not be achieved in five patients, and valve replacement was necessary.

The pathophysiology of mitral regurgitation
2012The results of treatment of heart valve disease have improved steadily during the past 20 years. In aortic stenosis, although postoperative survival rates approximated those of age-matched controls, the outcome of surgery to treat ischemic and non-ischemic mitral regurgitation was grave. The reasons for this were two-fold: first, patients were referred

Prophylactic mitral reconstruction for mitral regurgitation
The Annals of Thoracic Surgery, 2001Mitral regurgitation (MR) will produce myocardial dysfunction. The goal of this study was to review outcomes of mitral valve reconstruction in asymptomatic patients with severe MR.From 1992 to 2000, 93 asymptomatic patients with degenerative disease and severe MR underwent mitral valve reconstruction.
