Mitral regurgitation jet by color Doppler echocardiography

Apical four chamber view showing LV (left ventricle), RV (right ventricle), RA (right atrium), LA (left atrium) and AML (anterior mitral leaflet) with a small mitral regurgitation (MR) jet [..]

Estimation of Right Ventricular / Pulmonary Artery Pressure by Doppler

Estimation of right ventricular / pulmonary artery systolic pressure is done by Doppler echocardiographic measurement of the tricuspid regurgitaion jet velocity. From the jet velocity, the gradient is [..]

M-Mode Echocardiographic Measurements 1

M-Mode Echocardiography has good temporal resolution. Hence measurements of the left ventricle are often taken with M-Mode. End diastolic and end systolic volumes are estimated from these measurements. [..]

Cardiology X-ray Quiz 9

The X-ray shows gross enlargement of the cardiac silhouette. The right border extends far to the right indicating gross right atrial enlargement. Presence of an associated pericardial effusion [..]

Echocardiogram in Mitral Stenosis 2

Left panel shows pulse Doppler tracing with an early diastolic E wave and a late diastolic A wave (during atrial systole). In normal persons, there will be a gap [..]

Echocardiogram in Mitral Stenosis 1

Left panel shows the parasternal long axis view (PLAX). AO: Aorta; MVO: Mitral valve opening; LA: left atrium. Doming of the anterior mitral leaflet is seen well and [..]

Proximal Isovelocity Surface Area (PISA) method for estimation of mitral regurgitation

Proximal Isovelocity Surface Area (PISA) method is based on the continuity equation. When a flow passes through a narrow orifice, as it approaches the narrowest region, there is [..]
