Single coronary artery: classification and clinical significance

SUMMARY

Objectives: To evaluate ratio and classification single coronary artery in the MSCT cardiac.

Material and Methods: Prospective study of 9,868 patients who had scanner MSCT cardiac in Ha Noi Heart Hospital from February, 2015 to September, 2017.

Results: The study included 9,868 patients, 43 patients (0,44%) had single coronary artery. 11/43 patients (25,6%) had single coronary artery were isolated. 32/43 patients (74,4%) associated had congenital heart diseases other: 7 patients had Fallot 4, 3 patients had truncus arteriosus, 2 patients had pulmonary atresia, 1 patient had double outlet right ventricle, 1 patient had double discordance and 18 patients had complex congenital heart diseases. Included 43 patients had single coronary artery: 16/43 patients ( 37%) in the type R, 25/43 patients (58%) in the type L and 2/43 patients (5%) not in the current classification who had singler coronary artery high takeoff from truncus brachiocephalic artery. Type L I was 5%, type L II – A: 21%, type L II – B: 18%, type L II – P: 14%, type R II – A: 18%, type R II – B: 12%, type R II – P: 5% and type R III: 2%.

Conclusions: Singler coronary artery is a rare congenital anomaly. MDCT cardiac is a non-invasive technique, reliable, that provides accurate information about coronary artery anatomy well as other complex congenital heart diseases. Single coronary artery is a great challenge for surgery to repair the entire congenital heart disease that accompanies it.
