MCQ : CMR-12
26 years old boy, control for atypical chest pain. What do you think about the following images?
A – ASD with dilated right chambers and normal origin of coronary arteries
B – Persistent left superior vena cava (PLSVC) draining into the coronary sinus and normal origin of coronary arteries
C – ASD with dilated right chambers and anomalous origin of coronary arteries
D – Persistent left superior vena cava (PLSVC) draining into the coronary sinus and anomalous origin of coronary arteries
Correct Answer is D : Persistent left superior vena cava (PLSVC) draining into the coronary sinus and anomalous origin of coronary arteries
Persistent left superior vena cava (PLSVC) draining into the coronary sinus. QP/QS is normal, so no intracardiac shunt is present.
Right chambers are mildly dilated because of a moderate congenital tricuspid regurgitation.
The circumflex artery originates with the right coronary artery from the right coronary sinus and runs between the aorta and RVOT to reach the atrioventricular sulcus.
