Anomalous single coronary artery accompanied by accessory mammary tissue presenting with typical angina pectoris

33436

Single coronary artery is described as an isolated coronary artery originating from the aortic root through a single ostium in the absence of another ostium. The single coronary artery is the only source for blood supply to the whole heart. In this case we present a patient admitted to the outpatient clinic with typical chest pain, whose physical examination indicated accessory mammary tissue without any additional physical examination findings. The patient had hyperlipidemia and hypertension risk factors, and a coronary angiography was planned. The coronary angiography performed on the 72 year old male patient revealed a single coronary artery. According to the angiography, it is reported that the whole coronary system is distributed to the heart from a single trunk originating from the right sinus of valsalva. The multislice computerized tomography showed that the left anterior descending, circumflex and right coronary arteries originated from single trunk at the level of right sinus of valsalva through a single ostium without the left main trunk. There was no additional congenital anomaly. The patient, who had noncritical strictures, was discharged with medical treatment. Neural crest cells, matrix metalloproteinase, epidermal growth factor receptors, vascular endothelial growth factor and receptors are effective in the development of coronary arteries and mammary tissues in the embryonic phase. Any impact onthe migration routes of the neural crest cells or distortion of the synthesis of expression productsmay have caused this kind of an anomaly.
