Circulation, 2014 Background— Experimentally upregulating compliant titins has been suggested as a therapeutic for lowering pathological diastolic stiffness levels. However, how increasing titin compliance impacts global cardiac function requires in-depth study.

Estimation of End-Diastole in Cardiac Spectral Doppler Using Deep Learning
IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 2020Electrocardiogram (ECG) is often used together with a spectral Doppler ultrasound to separate heart cycles by determining the end-diastole locations. However, the ECG signal is not always recorded.

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.

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.

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

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.
