Mitral-valve replacement was performed in five patients with ruptured papillary muscle secondary to myocardial infarction. In each case severe mitral regurgitation was suggested by the sudden ...

Multimodality imaging can identify papillary muscles that are the source of arrhythmias. Increased echogenicity, gadolinium enhancement, and calcifications on papillary muscles can indicate site of ...

Also, use of a prosthetic ring for annuloplasty in growing children is a limitation. We have developed an alternative technique with right ventricular papillary muscle approximation (RV-PMA) and ...

In recent experiments we have been studying the effects of papillary muscle damage and inactivation on the function of the mitral valve and the left ventricle of the dog 2. In these experiments ...

Royalty-free licenses let you pay once to use copyrighted images and video clips in personal and commercial projects on an ongoing basis without requiring additional payments each time you use that ...

Background: Anomalous papillary muscle (APM) insertion into the mitral valve leaflet is rare but clinically important in hypertrophic obstructive cardiomyopathy (HOCM). In this study, we report the ...

RA, right atrium; RV, right ventricle; TV, tricuspid valve; A4C, apical four-chamber. Isolated tricuspid regurgitation caused by rupture of the papillary muscles or chordae tendineae is rare but fatal ...

Rowing machine muscles worked include the quads, glutes, triceps, and more, making it a great whole-body workout. This heart-pumping, high-intensity exercise activates many of the muscles that are ...

A consequence of myocardial infarction or primary dilated cardiomyopathy leads to left ventricular (LV) wall motion abnormalities, papillary muscle displacement, mitral annular dilatation, and ...
