Hemodynamics and annuloplasty in isolated mitral regurgitation in children.
Isolated mitral insufficiency in children is quantitated angiographically by comparing the stroke volumes of the right ventricle and left ventricle. The disease results in greater enlargement of the left atrium than of the left ventricle and is accompanied by a significant increase in left atrial "distensibility." Right and left heart pressures may be normal or may be increased; they tend to be...
متن کاملHemodynamics in ruptured chordae tendineae and chronic rheumatic mitral regurgitation.
Twenty-five patients with proven ruptured mitral chordae tendineae and 25 patients with chronic rheumatic mitral regurgitation were studied with quantitative biplane left-heart angiocardiography. Compared to the rheumatic patients, the ruptured chordae group had strikingly smaller left atrial maximum volume (mean: 119 + 47 vs 267 + 131 mI/M2 mean) and less compliant left atrium (mean: 1.61 1.52...
متن کاملThe role of multi-imaging modality in primary mitral regurgitation.
Primary mitral regurgitation (MR) is the first cause of valvular regurgitation in Western countries. Echocardiography is the cornerstone for diagnosing MR and more specifically for establishing its aetiology and mechanism, for quantifying its severity, progression, and repercussion and for assessing the likelihood of successful of valve repair. Two-dimensional/three-dimensional transthoracic an...
متن کاملLate gadolinium enhancement CMR in primary mitral regurgitation.
AIMS The appropriate timing for surgery in severe asymptomatic primary mitral regurgitation (MR) remains controversial. It has been shown that late gadolinium enhancement on cardiovascular magnetic resonance (LGE CMR), which may identify myocardial fibrosis, is associated with a worse outcome in various cardiomyopathies. We sought to investigate the prevalence and significance of delayed enhanc...
متن کاملRegional left ventricular deformation in primary mitral regurgitation
Introduction MVP is a common disorder affecting 2-3% of the general population. MVP patients with severe MR may remain asymptomatic for a number of years; however, LV systolic function may be impaired post-operatively, even among those with normal pre-operative ejection fraction (EF). Myocardial strain is the assessment of myocardial local deformation and may provide a more accurate assessment ...
