Long-term effect of papillary muscle approximation combined with ventriculoplasty on left ventricle function in patients with ischemic cardiomyopathy and functional mitral regurgitation.
OBJECTIVE One of the mechanisms of development of functional mitral regurgitation after myocardial infarction is the increased papillary muscle distance which results due to ventricle remodeling. The aim of this study was to investigate the long-term effect of papillary muscle approximation (PMA) on the cardiac function of patients with ischemic cardiomyopathy and increased papillary muscle dis...
متن کاملAssessment of Mitral Valve Complex by Three-Dimensional Echocardiography: Therapeutic Strategy for Functional Mitral Regurgitation
The mitral valve complex is consisted of annulus, leaflets, chordae tendineae, papillary muscle (PMs) and surrounding left ventricle. Functional mitral regurgitation (MR) results from left ventricular remodeling such as dilatation or distortion, which displaces the PMs and then tethers the mitral leaflets, restricting leaflet coaptation. Undersized annuloplasty, which has been widely accepted a...
متن کاملSolving the Puzzle of Chronic Ischemic Mitral Regurgitation
Chronic ischemic mitral regurgitation is a prevalent problem among patients following a myocardial infarction. Until recently, the pathophysiology was poorly understood, resulting in surgical strategies with suboptimal results and limited durability. The surgical approach has evolved from revascularization alone to an additional mitral valve procedure, replacement, or repair. When the valve was...
متن کاملMitral annular dilatation and papillary muscle dislocation without mitral regurgitation in sheep.
BACKGROUND Asymmetrical mitral annular (MA) dilatation and papillary muscle dislocation are implicated in the pathogenesis of functional mitral regurgitation (MR). METHODS AND RESULTS To determine the mechanism by which annular and papillary muscle geometric alterations result in MR, we implanted radiopaque markers in the left ventricle, mitral annulus, anterior and posterior mitral leaflets,...
متن کاملeComment: Which functional tricuspid regurgitation should be surgically corrected?
7. Clinical bottom line TV insufficiency should be treated during left-sided valve surgery when TR annulus is dilated (G21 mmym ;)70 mm 2 intra-operatively; G3.5 cm at trans-thoracic echocardio-graphy (TTE) w18x) regardless of the absolute grade of regurgitation, in cases of preoperative AF, trans-tricuspid PMK lead and underlying rheumatic disease. Also, 'ring' annuloplasty techniques should b...
