Dilated coronary sinus and Persistent Left SVC
Dilated Coronary Sinus
The agitated saline test confirms a persistent left superior vena cava (PLSVC) when contrast bubbles flow directly into the coronary sinus (CS) before entering the right side of the heart.
The differential diagnoses considering dilated CS and RCA were as follows.
Dilated coronary sinus
1. Conditions for elevated right atrial pressure and systolic pulmonary arterial pressure
2. Abnormal venous drainage in the coronary sinus
2.1 ) Persistent left superior vena cava
2.2 ) Total anomalous pulmonary venous connection
2.3 ) Unroofed coronary sinus
2.4 ) Coronary artery fistula
Dilated coronary artery or coronary artery aneurysm
-
Atherosclerosis
-
Coronary artery fistula
-
Kawasaki disease
