Abstract
Objective: Cardiac CT in preoperative evaluation of coronary artery anomalies in patients with tetralogy of Fallot.
Materials and methods: Forty-six patients diagnosed with tetralogy of Fallot by echocardiography underwent cardiac CT from Jan 2017 to Jan 2020 for coronary artery evaluation. CT findings were correlated with surgical findings.
Results: Three cases (6.5%) of anomalous coronary arteries were found in our study. One case showed anomalous origin of left anterior descending artery from right sinus of Valsalva. The second case revealed single coronary artery arising from left sinus of Valsalva and bifurcating into right coronary artery and left coronary artery. The third case showed anomalous origin of right coronary artery from left sinus of Valsalva with a malignant course.
Conclusion: Cardiac CT is an accurate and non-invasive modality in preoperative evaluation of coronary artery anomalies and avoiding damage during corrective surgery in patients with tetralogy of Fallot.
