Abstract:

A 40-year-old man was hospitalized in the coronary care unit with chest pain and abnormal electrocardiogram. Twenty days earlier, the patient underwent laparoscopic gallbladder surgery. Due to chest pain and ischemic ECG changes, patient was subjected to coronary angiography. The selective coronary angiography revealed multiple multilateral fistulae arising from the left anterior descending artery, circumflex artery, and the right coronary artery draining to the left ventricle. Multislice computed tomography showed hypoplastic coronary sinus and minor cardiac venous system. 1. Introduction Coronary-cameral fistulae are rare congenital or acquired malformation with a direct connection between the coronary arteries and heart chambers. The incidence of coronary artery ventricular fistulae was about 0.1% of congenital cardiac malformation and patients undergoing the coronary angiography [1, 2]. Most of them arise from the right coronary artery and drainage to the right side of the heart [3]. Multiple coronary artery fistulae originating from both the left and right coronary arteries are very rare [4]. Coronary-cameral fistulae mostly present as angina pectoris, syncope, myocardial infarction, heart failure, and cardiac arrhythmia. 2. Case Report A 40-year-old man was hospitalized in the coronary care unit with left sided chest pain and an abnormal electrocardiogram (T wave inversion in precordial leads) (Figure 1). The previous personal and family history of cardiovascular disease was empty. Twenty days prior to the admission, the patient was subjected to laparoscopic gallbladder surgery. The physical examination was normal. Echocardiography did not show any abnormality. All laboratory tests including troponin were within the reference range. Due to chest pain and ischemic ECG changes patient was subjected to invasive cardiology investigation. The selective coronary angiography revealed multilateral multiple fistulae arising from the left anterior descending artery, circumflex artery, and the right coronary artery draining to the left ventricle. There was no significant atherosclerotic lesion in the coronary arteries (Figures 2, 3, 4, and 5). Right heart catheterization showed normal pressure and oxygen partial pressure in the right atrium, right ventricle, and pulmonary arteries. With the right heart catheterization coronary sinus did not show. Multislice computed tomography showed hypoplastic coronary sinus and minor cardiac venous system (Figure 6).
