Aneurysm of the left coronary artery (case report)
Background: clinical case of a rarely encountered pathology (0.1-3.5%) in cardiac surgery, such as the aneurysm of the left coronary artery (LCA), is presented. It was detected and analyzed by coronary angiography and coronary CT angiography Aim: was to show possibilities of radiation research methods in identifying and evaluating of coronary artery aneurysms. Materials and methods: a 67-year-old patient was referred to the Federation National Center of Cardiovascular Surgery (Penza) for follow-up examination (coronary angiography) and to decide on the choice of management due to the presence of critical aortic valve stenosis. Performed coronary angiography and subsequent coronary CT angiography for demonstrate the topography of the aneurysm. Results: according to the data of coronary angiography at the region of trifurcation of the LCA or the anterior descending artery, intermediate and circumflex arteries a large-sized aneurysm is visualized. Due to coronary CT angiography data, the one is located at a distance of 1.0 cm from the entrance of the LCA in the area of trifurcation. It's presented by an aneurysmal dilatation of a rounded shape 1.3 cm in diameter with locally calcific walls. Conclusion: coronary angiography and coronary CT angiography made it possible to identify anc examine individual morphological features of the anatomy of the coronary artery aneurysm, as well as demonstrate and take apart its topography to clearly, which in turn made it possible to rationally determine the management of the patient
