Cardiology Clinics, 2000 Modeling methods have been employed to further characterize the physical and physiologic processes of filling and diastolic function. They have led to more detailed understanding of the effect of alteration of physiologic parameters on the Doppler E-wave contour as well as pulmonary vein flow.

Diastolic Ventricular Interaction and Ventricular Diastolic Filling
Heart Failure Reviews, 2000Because the ventricles share a common septum, the filling of one may influence the compliance of the other, a phenomenon known as direct diastolic ventricular interaction (DVI). This interaction is markedly enhanced when the force exerted by the surrounding pericardium is raised (pericardial constraint). In health, in the resting state, we operate near

Cardiology in Review, 1998
The pumping function of the left ventricle depends both on its ability to empty and its capacity to fill at a low pressure. Diastolic dysfunction occurs when filling of the left ventricle necessary to produce an adequate cardiac output requires an elevated pulmonary venous pressure.

Early diastolic overinflation in diastolic mitral regurgitation
Journal of Echocardiography, 2012An 81-year-old man presented with exertional dyspnea at our hospital. An electrocardiogram was recorded, which showed 2:1 atrioventricular (AV) block. Transthoracic 2-dimensional echocardiography showed that the left ventricular (LV) wall thickness and wall motion were normal. Color Doppler echocardiography showed no significant valvular heart disease.

Current Treatment Options in Cardiovascular Medicine, 2004
Heart failure is a leading cause of hospital admissions in North America. Approximately half of patients with symptoms of heart failure have normal or minimally impaired systolic function and are therefore diagnosed, by exclusion, with diastolic dysfunction. The therapy of diastolic dysfunction to date is largely unsatisfactory.

Heart Failure Clinics, 2008 The isovolumic period following systolic ejection is associated with untwisting of the apex that follows systolic torsion of the left ventricle, with simultaneous generation of negative pressures in the left ventricle. Previous studies have described this period as isovolumic relaxation, and have regarded the untwisting as entirely caused by restoring ...

Diastolic coronary resistance and capacitance are independent of the duration of diastole
American Journal of Physiology-Heart and Circulatory Physiology, 1991Systolic myocardial contraction may produce changes in coronary resistance and capacitance that persist throughout a normal diastole. In addition, coronary resistance and capacitance as determined in the arrested heart may not accurately describe normal diastolic behavior.
