Abstract
Although coronary artery anomalies may cause some clinical symptoms, most are incidentally discovered as benign findings on coronary angiograms. A circumflex coronary artery anomalously originating from the right sinus of Valsalva is the most common coronary anomaly. However, a double circumflex coronary artery, both stenotic in their mid portions, resulting in symptomatic heart failure is a rare clinical and angiographic condition. In this case, we present a 71-year-old male patient admitted to our clinic with the diagnosis of acute heart failure. Angiography revealed stenotic double circumflex arteries, arising from the left and right sinus of Valsalva, and the patient was treated by percutaneous coronary intervention.
