Step 5: visualization and reconstruction of the right coronary artery.
Panel A: ICE catheter is withdrawal under the HIS location with the US beam directed upwards. Aorta and PA are both visualized in the long axis view; sometimes, at this, level the origin of right coronary artery can be traced. Panel B: slight clockwise rotations allow to follow and reconstruct the proximal course of the R_CORO in the AV groove. Further RV volume can be filled in. ICE: intracardiac echocardiography, US: ultrasound, PA: pulmonary artery, AV: atrioventricular, RV: right ventricle.
