Traumatic intramyocardial left ventricular dissection: a case report.

In this report, we present an unusual case of a patient who sustained and survived an intramyocardial dissecting hematoma with subacute ventricular rupture complicating a motor vehicle accident. In conclusion, we report on the diagnosis, management, and prior literature of this highly unusual and often lethal condition.

Quantitative estimation of left ventricular ejection fraction from mitral valve E-point to septal separation and comparison to magnetic resonance imaging.

This study tested the hypothesis that the mitral valve E point-to-septal separation (EPSS) can be used to quantify the left ventricular (LV) ejection fraction (EF) on a continuous scale rather than simply as "normal" or "reduced." After excluding 5 patients with mitral valve prostheses, asymmetric septal hypertrophy, or significant aortic insufficiency, EPSS was measured in 42 patients by 3 independent observers on a cardiac magnetic resonance image identical to the echocardiographic parasternal long-axis view. In each patient, the reference standard LVEF was calculated from the magnetic resonance short-axis cross-sectional stack images by Simpson's rule and ranged from 11% to 72%.
