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.
