Acute thrombotic occlusion of Non-dominant right coronary artery presenting as acute coronary syndrome and hemodynamic instability

It is generally believed that the occlusion of a non-dominant right coronary artery is not associated with significant consequences. Atherosclerotic disease of non-dominant right coronary in the absence of significant left coronary artery disease is rare, and the prevalence is substantially lower as compared to dominant right coronary artery. We report a case of young male presenting with acute coronary syndrome and hemodynamically significant atrial fibrillation. Coronary angiography showed thrombotic occlusion of non dominant right coronary artery. After the stenting of this artery, patient improved hemodynamically with complte resolution of ECG changes.
