Single Coronary Ostium

Advanced diagnostic systems and healthcare screening programs enabled increased diagnosis of congenital cardiovascular anomalies, including variations in coronary arteries. Single coronary artery is a rare congenital cardiovascular malformation in which all three main coronary arteries originate from a single coronary trunk. In this report, we present a patient with single coronary ostium giving rise to the left and right coronary artery systems, which was diagnosed incidentally with coronary computerized tomography and confirmed with conventional angiography.

Iranian Patients

Coronary artery anomalies are common among patients with tetralogy of Fallot. One hundred and thirty-five patients (80 males and 55 females) with tetralogy of Fallot who underwent repair between 1995 and 2002 were studied to determine the incidence of coronary anomalies in Iranian patients. Eight (5.9%) patients (4 males and 4 females) had a surgically relevant coronary artery anomaly: single coronary ostium in 5, origin of the left anterior descending artery from the right coronary artery in 2, and origin of the right coronary artery from the left coronary artery in 1. The surgical technique in 3 of these patients was repair of the ventricular septal defect with a transverse incision on the right ventricle, without damage to the coronary arteries. In another patient, an allograft aortic valve cylinder was inserted. In the other 4 patients with a single coronary ostium, placement of a limited transannular patch was adequate. Consideration of these anomalies during primary repair could decrease the risk of operation in such patients. However, it seems that the presence of anomalous coronary arteries does not affect incremental risk after surgical repair.

Single Coronary Ostium

Multiperforated atrial septal aneurysm (ASA) with left-to-right shunt and elevated pulmonary arterial pressure is rare. We present an adult patient with this unusual anomaly combined with a single coronary ostium emerging from the right sinus of Valsalva. The ASA was excised and the defect repaired successfully.

Aortic Cuff

A 14-year-old boy was diagnosed with an anomalous left coronary artery coursing between the ascending aorta and the main pulmonary artery and associated with a single coronary ostium. Owing to the high risk of sudden cardiac death, surgery was performed although he was asymptomatic with no sign of myocardial ischemia. Reimplantation of an anomalous left coronary artery is generally considered difficult because an aortic cuff is unavailable for coronary anastomosis; however, we accomplished a successful direct reimplantation in this patient. This procedure offers another choice in the surgical treatment of anomalous left coronary artery.

Diagnostic Potential

Herein we report the diagnostic potential of cardiac computed tomography (cCT) to delineate the origin and course of an anomalous right coronary artery (RCA) originating from the midpart of the left anterior descended artery (LAD) in an adult with no other form of congenital heart disease. The patient was referred to our institution due to exertional dyspnea and suspected coronary artery disease. The patient underwent X-ray coronary angiography, and no high grade lesions were observed in the left coronary vessels. In the course of the mid-left-anterior-descending artery (LAD), an anomalous side branch coursing away from the left circumflex coronary artery (LCX) was observed, while a right coronary ostium could not be depicted. cCT confirmed the absence of a right coronary ostium, and the vessel originating from the mid LAD was identified as an anomalous RCA, which coursed anterior of the aorta and the pulmonary trunk.

ABSTRACT Were used twelve (12) adult anteaters (Myrmecophaga tridactyla), adults, 6 (six) males and 6 (six) females, weighing from 20 to 27.32kg from free life. The thoracic cavity was opened until visualization of the whole heart and lungs and later injection of the coronary vessels. The right coronary artery emerged through a single coronary ostium of the aorta, 50%, emitting the intermediate branch and the subsinuous interventricular branch, had a path directed to the subsurface interventricular groove. In the other 50%, the right coronary artery was not present, showing only its branches, intermediate branch and subsurface interventricular branch with emergence of the aorta. Left coronary artery presented, in 83.33%, origin from the aorta in single ostium, issuing the circumflex and interventricular paraconal branches. In 16.66%, the left coronary artery was not evidenced originating from the aorta, but its branches, circumflex and interventricular paraconal.
