چکیده انگلیسی
Intercoronary communication or 'coronary arcade' is a rare congenital coronary anomaly. We present the case of a 65âyearâold man with atypical chest pain for four months. The 12âlead ECG and echocardiogram were normal. Treadmill exercise testing was interrupted at peak exercise due to consecutive salvos of ventricular premature beats, without significant STâT changes. Coronary angiography showed no significant coronary stenosis, but a connection between the right coronary and circumflex arteries was observed, consistent with coronary arcade. The functional importance of this variant is not clear, but it may cause myocardial ischemia by coronary steal or function as a natural bypass, in which case it may play a protective role in the myocardium if significant atherosclerosis develops.
