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 part by ...

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 ...

Papillary muscle scarring in DCM patients is associated with higher risks of cardiac death, heart failure, and arrhythmia events. Microvascular dysfunction is a strong predictor of poor prognosis, ...

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 ...

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 ...

Within the prior 24 months, I have had a financial relationship with a company producing, marketing, selling, re-selling, or distributing healthcare products used by or on patients: Study honoraria to ...

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 ...
