Estimation of left ventricular filling pressures from tissue Doppler

Estimation of left ventricular filling pressures from tissue Doppler data can be obtained from the correlations obtained from previous simultaneous cardiac catheterization and tissue Doppler studies. The ratio [..]

Stress tissue Doppler imaging (stress echo with tissue Doppler)

An important limitation with stress tissue Doppler imaging (stress echo with tissue Doppler) is the technical challenge of acquiring both two dimensional and tissue Doppler echocardiographic information during [..]

Dual Doppler echocardiography

Dual Doppler echocardiography is the technique of simultaneously recording Doppler signals of two types. This technique is used for recording left ventricular filling (E wave) and e’ (mitral [..]

Carpentier nomenclature of mitral leaflet scallops

Carpentier nomenclature of mitral leaflet scallops is important in assessing the mitral leaflets while planning echo. The scallops can be identified well by trans esophageal echocardiography, preferably in [..]

Merlon sign and square root sign in endomyocardial fibrosis

Merlon sign in endomyocardial fibrosis is characterized by a hypercontractile basal ventricle opposing an obliterated apex. There is a diastolic bulge of the interventricular septum into the left [..]

Ventricular septal defect – perimembranous

Perimembraneous ventricular septal defect (VSD) Medium sized ventricular septal defect in peri-membranous location seen from the apical five chamber view. RV: right ventricle; LV: left ventricle; VSD: ventricular [..]

Vegetation on tricuspid valve – echocardiographic image

Vegetation on tricuspid valve Vegetation on tricuspid valve seen on echocardiography from a modified apical four chamber view. LV: left ventricle; LA: left atrium; RV: right ventricle; RA: [..]

Tricuspid regurgitation severe and mild

TR Colour Jet Colour Doppler echocardiogram in apical four chamber view (slightly tilted) showing tricuspid regurgitation jet. Right ventricle (RV) is seen dilated and hypertrophied, with a prominent [..]

Parasternal long axis view in echocardiography

Parasternal long axis view in echocardiography Parasternal long axis view is usually the first view which is obtained in echocardiography. The transducer is placed in the left parasternal [..]

Flail posterior mitral leaflet (PML) and mitral regurgitation

Flail PML Two dimensional (2D) echocardiographic image showing right ventricle (RV), aorta (A0), left atrium (LA), left ventricle (LV) and the flail posterior mitral leaflet (PML) which points [..]
