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 ...

Papillary muscle scarring (papSCAR) is prevalent in one-third of DCM patients and predicts cardiac death independently. The FIDDLE technique significantly improves papSCAR detection sensitivity ...

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 part by ...

THE genesis of rheumatic valvular disease in man has been difficult to establish owing to the scarcity of human material in the early stages and the absence of any comparable condition in experimental ...

TCT 1019: Complex degenerative mitral valve disease with a posterior cleft and severe regurgitation successfully treated using a single PASCAL Ace device with horizontal positioning. Receive the the ...

The mitral valve allows blood to flow from the left atrium of the heart into the left ventricle. Mitral regurgitation occurs when the mitral valve leaks blood back into the left atrium. A person’s ...

Electrical reexcitation of rat papillary muscle after a short interval (50 to 80 milliseconds) results in action potentials with no significant mechanical counterpart. The mechanical response recovers ...
