If the left circumflex coronary artery crosses the crux of the heart (junction of interventricular and interatrial grooves posteriorly) to the opposite side, it is known as the
Cardiac resynchronization therapy (CRT) is biventricular pacing in which one lead paces the right ventricle endocardially, another the left ventricle epicardially through a coronary vein and a third
Belhassen's VT is a fast rhythm originating from the left ventricle. VT is short for ventricular tachycardia. It is named after the person who described it as a
ECG shows inverted P waves in inferior leads, indicating that atrial activation is spreading from below upwards, suggestive of focus in low atrium / high junction.
Pressure half time of aortic regurgitation jet is measured from the apical five chamber view using continuous wave Doppler echocardiography. Pressure half time decreases as the severity of
Commonest arrhythmia in the transplanted heart is typical cavotricuspid atrial flutter. Atrial fibrillation is uncommon due to either pulmonary vein isolation or denervation.
Rastelli procedure is done in cases of D-Transposition of great arteries with left ventricular outflow tract obstruction and ventricular septal defect, when arterial switch is not feasible.
On LV (left ventricle) to aorta pull back, aortic pressure rises due to relief of the enhanced obstruction of the aortic orifice which had occurred while entering the
