Pulmonary artery wedge pressure measurement: Catheter tip should be reasonably peripheral on fluroscopy and should not move with the cardiac systole.

Magnetic resonance imaging in congenital heart disease: indications, advantages and special modalities in CMR.

Cardiac musculature: Circular and oblique spirals of cardiac musculature are seen in the left ventricle, while longitudinal spirals are seen in the RV.

Important terminologies in coronary angioplasty.

Left coronary angiogram showing tight proximal left anterior descending (LAD) coronary artery lesion in the right anterior oblique (RAO) caudal view (arrow).

Estimation of right ventricular systolic pressure by Doppler echo is done from the apical four chamber view. Peak gradient of TR jet is calculated.

ECG showing Anterior wall myocardial infarction and 50 Hz interference.

ECG showing complete heart block and intermittent pacing.

Infective endarteritis is less likely in very small or large PDA as, a high velocity jet causing endothelial damage is unlikely. It is more likely in moderate sized

Dilated ascending aorta seen on contrast enhanced CT scan of thorax in coronal section.
