Coronary Artery Anomalies in Tetralogy of Fallot

In order to evaluate the preoperative coronary arterial anatomy in patients with tetralogy of Fallot before total correction, we used a new selective coronary angiographic method in 62 patients between April 1994 - July 1995. There were 62 patients (36 male and 26 female) aged ı - 13 (mean 3.ı6 ± 2.ı7) years, their weight ranged from 6.7 to 32 (mean ı2±4 . 44) kg. Coronary angiography was performed in the lateral, left anterior oblique, 30° left anterior oblique, 40° caudal (aortic orifice view), posterior-anterior and right anterior oblique positions. In the evaluation of the coronary angiograms, we found single coronary orifice in 3 (%4.8) patients (1 with single right, 2 with single left), a left anterior descending (LAD) arising from the right coronary artery and crossing the right ventricular outflow tract (RVOT) in ı patient (1.6 %), accessory LAD (two of them crossing the RVOT) in 4 patients (6.5 %), large conal branch in 9 atients (1 4.5 %), coronary-branchial eellateral in 13 patients (20.9 %) and right coronary artery-right atrium fistula in ı patient. The anomalous coronary artery-RVOT relation was seen best in the "aortic orifice view" position. We conclude that selective coronary angiography can demonstrate in detail the coronary arterial anatomy and anomalies which are frequently seen in patients with tetralogy of Fallot
