Ultrasound and 64-MSCT Diagnosis of Congenital Coronary Artery Fistula

Purposes:To evaluate ultrasound(US) and 64-multislice computed tomography(64-MSCT) in diagnosing congenital coronary artery fistula(CAF).Methods:Clinical data of 7 cases with CAF confirmed by surgical operation were retrospectively analyzed,and image features of CAF shown by US in 7 cases and 64-MSCT in 3 were compared.Results:Seven patients with CAF were correctly diagnosed by US,of which 3 cases also by 64-MSCT.They were found only at unilateral coronary artery(CA),3 cases were in the right side and 4 were in the left.CAF drained into the right heart or lung artery system in 4 cases and into the left heart in 3.Both US and 64-MSCT can show the enlarged coronary arteries and its origin,fistula and draining antrum or ventricle or blood vessel.US is advantageous in observing the cardiovascular dynamics and 64-MSCT in showing the whole pathology and peripheral structure or calcification.Conclusion:US can act as the routine examination of CAF,and 64-MSCT can provide more information for the choice of surgery.
