Abstract
[...]coronary sinus (CS) abnormalities were observed during the implantation operation. [...]it was forced to stop the operation and a cardiac computed tomography angiography (CTA) evaluation of the abnormalities was arranged. TTE assesses a lesion after the injection of agitated saline (air-filled microbubbles are created by shaking the saline solution in a syringe), but the accuracy of the ultrasonography diagnosis depends on the operator's experience and examination skills. [...]ultrasonography cannot visualize the entire course of a PLSVC because of acoustic window limitations and obstructions caused by bones and gases. [...]this shorter duration necessitates tighter contrast enhancement protocols, and venous opacification may be insufficient using scanning protocols optimized for imaging the coronary artery system. [...]a longer duration may be required between contrast injection and scanning initiation to visualize the cardiac veins.
