Percutaneous Transluminal Angioplasty of a single coronary artery
- Groudeva, D. Dimitrov, M. Nedevska
Coronary artery anomalies are infrequently encountered during coronary angiography. However most of them are with benign course and do not have clinical presentation themselves. Although atherosclerosis is known to occur in coronary anomalies. Percutaneous transluminal angioplasty /PTCA/ treatment of stenosis in coronary anomalies is challenging due to the possible technical impediments in the attempts to cannulate and stent the anatomically altered vessel. We describe a case of a patient with a single coronary artery, which originates from the right aortic cusp and with a significant stenosis of acute marginal artery noticed during coronary angiography. Anomalous course of the coronary vessel and its anatomical characteristics as well as the significant stenosis were demonstrated additionally by MDCT. The patient underwent interventional treatment and stent placement which was complicated with coronary artery dissection. Patient was left on conservative treatment and follow up angiography showed complete resolution of the dissection. Catheter treating coronary artery anomalies is challenging and preprocedural computed tomography coronarography planning is essential.
