Percutaneous transluminal coronary angioplasty (PTCA) Here is an illustrated review of steps in percutaneous transluminal  coronary angioplasty (PTCA) of left anterior descending (LAD) coronary artery: Balloon inflation in

Description of device closure of atrial septal defect (ASD) by the transfemoral route.

Mitral regurgitation jet by color Doppler echocardiography. Vena contracta is the narrowest portion of the MR jet at or just beyond the regurgitant orifice. It is an accurate

Left ventricular angiogram in right anterior oblique view - systolic and diastolic frames.

Aortic flow velocity by Doppler echo is routinely measured and is useful to assess aortic gradient in aortic stenosis. It is also useful in calculating valve area by

Right coronary angiogram showing conus branch, sinus node artery, right ventricular branches, posterior descending coronary artery and the stump of posterior left ventricular branch.

Estimation of Right Ventricular / Pulmonary Artery Pressure by Doppler echocardiography using Modified Bernoulli equation.

M-Mode Echocardiography has good temporal resolution. Hence measurements of the left ventricle are often taken with M-Mode.

Peripheral signs of aortic regurgitation (AR) are mostly due to the high stroke volume and high pulse pressure. These are features of aortic run off and can occur

Color Doppler Echocardiogram in Mitral Stenosis showing thickened and domed mitral leaflets, turbulent colour jet across the mitral valve in the right panel and Doppler tracing with E
