Abstract:

In this review, we discussed about updated concept about diastolic dysfunction of left ventricle and mechanism behind the diastolic heart failure with normal Ejection fraction of LV using modern and advanced non-invasive technique of 2D Echocardiography. In actual way, the invasive data obtained from cardiac catheterization is considered the gold-standard to study LV filling pressures and LV pressure volume curves. 2D Echocardiography with advanced technology is useful, affordable and more convenient to the patients those who have Hypertension, diabetes, thyroid disorders, infiltrative, restrictive or hypertrophic cardiomyopathy, valvular disorders, pericarditis, severe pulmonary hypertension and pre and post operative procedures. We can differentiate diastolic heart failure from systolic heart failure based on parameters such as increased myocardial stiffness, delayed isovolumic relaxation, increased LV filling pressure and decreased LV Compliance but preserved LV Ejection fraction or systolic function when patients present with dyspnoea on exertion or worsen heart failure.

Keywords-2D Echocardiography, diastolic functions, heart failure, advanced diastology.
