Abstract:
Echocardiography is the first step in imaging the right heart pulmonary circulation unit (RH-PCU), and the only one to allow its complete morphologic, functional, and hemodynamic analysis in all clinical scenarios. Right ventricular (RV) function is not only the consequence of its intrinsic contractile function (morphology and contractility) but also highly dependent on preload, afterload, and ventricular interdependence. Comprehensive echocardiographic examination of RH-PCU allows insight into intrinsic and extrinsic factors of RV function. Newer echocardiographic techniques allow for 3-dimensional evaluation of RV and detailed measurements of regional function using tissue Doppler or speckle tracking-based strain estimates.

Overview of Pulmonary Circulation
The process begins with the right ventricle of the heart pumping deoxygenated blood into the pulmonary trunk. This large vessel extends about 5 centimeters before splitting into the left and right pulmonary arteries. These arteries...

Coronary Circulation
Coronary circulation begins at the base of the aorta, where two main arteries arise—the left and right coronary arteries. These arteries encircle the heart in the coronary sulcus and supply the...
