Mitral regurgitation.
Accurate clinical assessment of the severity of mitral regurgitation is often difficult, and left ventricular cine-angiocardiography is probably the most commonly used method of estimating it. It is therefore important to try to determine the accuracy of this method and to identify as far as possible any causes of error. We have attempted to do this in a series of 137 patients submitted to oper...
متن کاملMITRAL REGURGITATION Quantitation of mitral regurgitation by Doppler echocardiography
The evaluation and care of patients with mitral regurgitation would be facilitated by an easy, reproducible and noninvasive method that could quantitate the hemodynamic burden. In this study, we describe a new Doppler echocardiographic method that measures the regurgitant fraction and we compare it with angiographic and scintigraphic methods. A total of 27 patients with mitral regurgitation wer...
متن کاملPossible Effect of CABG on Moderate Mitral Regurgitation
Introduction: Mitral valve insufficiency in adults is often a complication of ischemic heart disease. Coronary artery bypass grafting (CABG) is performed as a strategy for the treatment of coronary artery disease. The aim of this study was to evaluate mitral regurgitation (MR) before and after CABG. Materials and Methods: This Experimental study was condu...
متن کاملIschemic Mitral Regurgitation
Ischemic mitral regurgitation (IMR) is a frequent complication of left ventricular (LV) global or regional pathological remodeling due to chronic coronary artery disease. It is not a valve disease but represents the valvular consequences of increased tethering forces and reduced closing forces. IMR is defined as mitral regurgitation caused by chronic changes of LV structure and function due to ...
متن کاملQuantification of Mitral Regurgitation
Background. In clinical color Doppler examinations, mitral regurgitant jets are often observed to impinge on the left atrial wall immediately beyond the mitral valve. In accordance with fluid dynamics theory, we hypothesized that a jet impinging on a wall would lose momentum more rapidly, undergo spatial distortion, and thus have a different observed jet area from that of a free jet with an ide...
