Fig. 1
Origin of the right coronary artery from the pulmonary artery visualized in ECHO 2D, in modified cross-sectional vascular parasternal projection. PA – pulmonary artery, Ao – cross-section of the initial segment of the ascending aorta, RCA – right coronary artery, LA – left atrium, RA – right atrium, Th – thymus, IAS – interatrial septum
Fig. 2
Preoperative ECHO. Modified cross-sectional parasternal vascular projection. See the inflow from the right coronary artery to the pulmonary artery. Ao – cross-section of the ascending aorta, PA – pulmonary artery trunk, RCA – right coronary artery, RVOT – right ventricular outflow tract, RA – right atrium, Sh – RCA-PA shunt.

Epicardial intraoperative imaging visualizing the flow in the right coronary artery implanted to the aortic bulb of the right coronary artery. Presently, the flow directed upward is uniform red color-coded (laminar flow). PA – pulmonary regurgitation filling the outflow tract from the right ventricle. Ao – cross-section of the aortic bulb, RCA – right coronary artery

Postoperative ECHO. The initial segment of the right coronary artery in postoperative examination (18 days postoperatively). In order to achieve appropriate resolving power, a linear transducer was employed along with the color Doppler scale allowing representation of low flow rates (0.15m/s). Due to the arched course of the coronary artery making it impossible to capture the entire initial segment in a single image, two image frames are presented visualizing the consecutive fragments of the vessel. Uniform, laminar flow from the aorta (red color-coded) was visualized along the entire length of the examined vessel. Ao – aortic bulb, PA – initial segment of the pulmonary trunk, RCA – right coronary artery
