The mitral apparatus. Functional anatomy of mitral regurgitation.
This review deals with the functional anatomy of the six components of the mitral apparatus, namely, the left atrial wall, annulus, leaflets, chordae tendineae, papillary muscles, and left ventricular wall. Each component is considered individually, in the context of the apparatus as a whole, in relation to the mode of closure of the normal mitral valve, and in the light of many acquired and co...
متن کاملProgression of tricuspid regurgitation after repaired functional ischemic mitral regurgitation.
BACKGROUND Despite correction of left-sided cardiac lesions, associated functional tricuspid regurgitation (TR) that was surgically ignored can persist. It can also appear de novo. The aim of this study was to analyze TR in a group of patients who underwent successful revascularization and mitral valve repair (MVRep) for functional ischemic mitral regurgitation (MR). METHODS AND RESULTS Among...
متن کاملValve Disease Functional Anatomy of Mitral Regurgitation Accuracy and Outcome Implications of Transesophageal Echocardiography
RESULTS Compared with surgical diagnosis, the accuracy of TEE was high: 99% for cause and mechanism, presence of vegetations and prolapsed or flail segment, and 88% for ruptured chordae. Diagnostic accuracy was higher for TEE than TTE for all end points (p ! 0.001), but the difference was of low magnitude (!10%) except for mediocre TTE imaging or flail leaflets (both p ! 0.001). The type of mit...
متن کاملFunctional anatomy of mitral regurgitation: accuracy and outcome implications of transesophageal echocardiography.
OBJECTIVES This study was performed to determine the accuracy and outcome implications of mitral regurgitant lesions assessed by echocardiography. BACKGROUND In patients with mitral regurgitation (MR), valve repair is a major incentive to early surgery and is decided on the basis of the anatomic mitral lesions. These lesions can be observed easily with transesophageal echocardiography (TEE), ...
متن کاملAnatomy of the mitral valve: understanding the mitral valve complex in mitral regurgitation.
Imaging the mitral valve requires an understanding of the normal anatomy and how this complex structure is altered by disease states. Mitral regurgitation is increasingly prevalent. Despite the fall in rheumatic disease, it is the second most common valvular lesion seen in adults in Europe. In this review, the morphology of the normal and abnormal valve is reconsidered in relation to the key st...
