If a catheter passes from the right ventricle into the descending aorta, what are the possibilities?
It could be passing through a ventricular septal defect (VSD), patent ductus arteriosus (PDA) or aortopulmonary window (AP window) into the descending aorta. In VSD and AP window, the catheter will form an open loop while in PDA the catheter will form a closed loop (closed loop catheter course in PDA) as it crosses from the pulmonary artery into the descending aorta.
