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 ...

Ischemic malfunction of the papillary muscles was thought to cause mitral regurgitation as early as 1935, 8 and this mechanism was further emphasized by Burch and Phillips . . . Supported in ...

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 ...

Arm muscle anatomy refers to the location and function of the muscles of the arms. These muscles attach to the shoulder blade, upper arm bone (humerus), forearm bones (radius and ulna), wrist, fingers ...

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 ...

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 ...

Findings from the KEYNOTE-057 trial showed that pembrolizumab (Keytruda) is an effective treatment option for patients with bacillus Calmette-Guérin (BCG)-unresponsive, papillary high-risk ...

To improve preoperative understanding of mitral valve anatomy and enable preoperative simulation of mitral valve repair, patient-specific mitral valve replicas have been developed. However, most of ...
