Abstract
Purpose. Until the mid-20th century they could be discovered only during autopsy, it means after death. With the introduction of coronary angiography it become possible to find them in a living person. Later on, new modalities such as computed tomography (CT) and magnetic resonance imaging (MRI) enhanced futher our abilities. It is very important to discover coronary anomalies in a living person, because some of them could lead to sudden cardiac death (SCD). In fact, coronary artery anomalies are the second main cause of the SCD in young athletes. Another importance is driven by the fact, that some of them could lead to lifethreatening complications during cardiac surgery when unknown before the operation.
Methods. We prospectively reviewed all coronary angiography films from 2011 to 2016 in our center. Coronary anomalies were reviewed and classified by two independent experienced operators. Patients with congenital heart disease and coronary fistulas were excluded.
Results. Out of 5055 patients 148 (2.9%) had coronary artery anomalies of origin and distribution. Those were 120 men (81.1%) and 28 women (18.9%) with an age range between 29 to 88 years. The three most common anomalies were myocardial bridge (48.7%), separate origin of the conus branch (13.5%) and separate origin of the LAD and LCX (8.1%).
Conclusion. In our study we found more or less the same types and incidence rates of coronary artery anomalies as in the world literature. We had apparently higher rates of myocardial bridges, compared to average number on angiography studies, but very close to authopsy study rates.
