Abstract

Intercoronary communication is a very rare coronary artery anomaly. It is defined as an open-ended circulation with bidirectional blood flow between two coronary arteries. Coronary artery fistulas are abnormal communications between a coronary artery and a cardiac chamber or major vessel. A 62-year-old man was admitted to our hospital with sudden development of general weakness, dizziness and a sensation of compression in his chest. At presentation his blood pressure was 80/40 mmHg and heart rate was 65 beats/min. The ECG revealed sinus rhythm and 1-2 mm ST elevation in the anterior leads. The patient was taken to the catheterization laboratory for percutaneous coronary intervention. The left main and left circumflex coronary arteries were normal. Coronary angiography showed a communication between the left main and the diagonal branch of the left anterior descending and a fistula between the intercoronary connection and the left atrium. The other coronary arteries were normal. Laboratory test results, including cardiac troponin I and creatine kinase-MB levels, were normal. The angina symptoms disappeared and the ST elevation resolved within four hours. We report an interesting case of congenital coronary artery fistula in an intercoronary communication between the left main and the diagonal branch of the left anterior descending coronary artery presenting as an acute coronary syndrome. To the best of our knowledge, this is the first case in the literature involving a coronary artery fistula in an intercoronary communication.
