Ischemic mitral regurgitation
ثبت نشده
چکیده
Ischemic mitral regurgitation (IMR) is a relatively frequent complication of myocardial infarction. The presence of IMR negatively influences imminent mortality after myocardial infarction and the long-term survival of the patients. IMR is a functional, not morphological impairment of mitral valve and is caused by a change in the geometry of the left ventricle. In the review article, the authors deal with the origin and pathophysiology of chronic IMR and with current possibilities for surgical treatment of this serious complication of ischemic heart disease.

اثر PercutaneousCoronary Intervention Elective بر بهبودی نارسایی ایسکمیک میترال
Introdution: Ischemic mitral regurgitation (IMR) remains one of the most complex and unresolved aspects of ischemic heart disease that the impact of percutaneous coronary intervention (PCI) on improvement of intensity of ischemic mitral regurgitation is not well clarified. Patients with coronary artery diseases and ischemic mitral regurgitation have a worse prognosis than the patients with coro...
متن کاملEchocardiographic assessment of ischemic mitral regurgitation
Ischemic mitral regurgitation is an important consequence of LV remodeling after myocardial infarction. Echocardiographic diagnosis and assessment of ischemic mitral regurgitation are critical to gauge its adverse effects on prognosis and to attempt to tailor rational treatment strategy. There is no single approach to the echocardiographic assessment of ischemic mitral regurgitation: standard e...
متن کاملMitral valve repair for ischemic mitral regurgitation: review of current techniques
INTRODUCTION Ischemic mitral regurgitation can be defined as moderate to severe mitral leak precipitated by acute myocardial infarction. Valve repair is now the procedure of choice, but some cases can pose difficult anatomy. This review will illustrate current techniques for repairing complex ischemic mitral regurgitation. METHODS Most patients with ischemic mitral regurgitation have predomin...
متن کاملSeptal-lateral annular cinching abolishes acute ischemic mitral regurgitation.
OBJECTIVE Ring annuloplasty prevents acute ischemic mitral regurgitation in sheep, but it also abolishes normal mitral annular and posterior leaflet dynamics. We investigated a novel surgical approach of simple septal-lateral annular cinching with sutures to treat acute ischemic mitral regurgitation. METHODS Nine adult sheep underwent implantation of multiple radiopaque markers on the left ve...
متن کاملThree-dimensional echocardiographic analysis of mitral annular dynamics: implication for annuloplasty selection.
BACKGROUND Proponents of flexible annuloplasty rings have hypothesized that such devices maintain annular dynamics. This hypothesis is based on the supposition that annular motion is relatively normal in patients undergoing mitral valve repair. We hypothesized that mitral annular dynamics are impaired in ischemic mitral regurgitation and myxomatous mitral regurgitation. METHODS AND RESULTS A ...
