Valve Disease Functional Anatomy of Mitral Regurgitation Accuracy and Outcome Implications of Transesophageal Echocardiography

چکیده
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 mitral lesions identified by TEE (floppy valve, restricted motion, functional lesion) were determinants of valve repairability and postoperative outcome (operative mortality and long-term survival; all p ! 0.001) independent of age, gender, ejection fraction and presence of coronary artery disease.

Functional 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 کاملIntraoperative transesophageal echocardiography accurately predicts mitral valve anatomy and suitability for repair.
Mitral valve (MV) repair is the procedure of choice for MV prolapse or flail. However, valve repair is more technically demanding and requires a precise definition of MV morphology to determine the timing, complexity, and feasibility of repair. We prospectively examined 170 consecutive patients with MV prolapse or flail referred for MV repair. The MV valve was systematically assessed by intraop...

OBJECTIVES We sought to assess the value of transthoracic echocardiography (TTE) using standardized imaging planes for the functional analysis of mitral regurgitation (MR) as well as for postoperative outcome implications. BACKGROUND The feasibility of mitral valve repair is based on functional assessment of MR, mainly by transesophageal echocardiography (TEE). Considering the recent advances...

Background: Mitral valve disease is the most common acquired heart disease in dogs. Mitral valve regurgitation (MR) due to endocardiosis is an important cause of morbidity and mortality in dog. Echocardiography as a non-invasive tool is routinely used to evaluate and diagnose different disorders in the heart. Objectives: The purpose of this study is to determine the efficacy of medical treatmen...
