Cardiac CT is the most accurate tool for diagnosing and evaluating coronary artery anomalies. Coronary anomalies can often be observed as the number of cardiac CT scans increases. In this review article, we described the CT findings and clinical significance of coronary anomalies that radiologists should know. In particular, we described the dangerous anatomical findings of coronary anomalies on CT images in detail.

In the surgical repair of tetralogy of Fallot, the anomalous origin of the coronary artery has significant surgical implication. The coronary anomalies of concern are origin of the anterior descending coronary artery from the right coronary artery and certain variations of single coronary branching. We experienced a case of tetralogy of Falloff with single coronary artery from the left coronary sinus, from which the right coronary artery originated crossing the right ventricular outflow tract. This ty e of coronary anomaly in tetralogy of Fallot is known to be extremly rare.

Vieussens' arterial ring (VAR) is the connection between the conus branch of the right coronary artery and the proximal right ventricular branch of the left anterior descending coronary artery. VARs are found in 48% of the population; however, pathologic VAR is rare. We experienced a case of pathologic VAR that involved a fistula connecting to the main pulmonary artery.

Single coronary artery is rare congenital anomaly with incidence about 0.04%. Above half of single coronary artery is symptomless, and about 41% of cases are associated with another congenital cardiac anomalies . Single coronary artery is sometimes important for cardiac operation to avoid fatal result from cutting of coronary artery during the right ventriculotomy. Among the associated anomaly of the single coronary artery, coronary arteriovenous fistula is very rare. We experienced congenital single coronary artery with coronary arteriovenous fistula drained into the right ventricle, and so we report this case with literatures.

Coronary artery fistula, defined as an abnormal communication between the coronary arteries and a cardiac chamber (most commonly) or a thoracic great vessel, may result in hemodynamically significant problems due to vascular shunting in children. Echocardiography, cardiac catheterization, cardiac MRI, and cardiac CT may be used to evaluate coronary artery fistula in children. Recently, CT has played a pivotal role for the accurate diagnosis of coronary artery fistula in children. Surgical or interventional treatment is performed for hemodynamically significant coronary artery fistulas. In this pictorial review, the detailed imaging findings of coronary artery fistula in children are described.

Dual left anterior descending artery (LAD) is a rare congenital coronary artery anomaly with a prevalence of approximately 1% in the general population. To date, 10 types of dual LAD artery anomalies have been reported. Among these, type 4 is one of the rarest. Knowledge and recognition of the dual LAD artery are important for correct diagnosis and planning of coronary bypass surgery and percutaneous coronary intervention. We report a case of a 59-year-old male with type 4 dual LAD artery who presented with dyspepsia and sweating for several months and had approximately 50%-70% stenosis in a major diagonal branch off the short LAD artery.

Coronary artery fistula is an abnormal communication between the coronary artery and the cardiac chambers. In particular, an abnormal connection between the conus branch of the right coronary artery and the proximal left anterior descending coronary artery is defined as Vieussens' arterial ring. Coronary artery fistulas are usually asymptomatic, but some can cause complications such as infective endocarditis. Here, we report a case of Vieussens' arterial ring causing infective endocarditis with severe mitral regurgitation.

Isolated anomalous right coronary artery originating from the pulmonary artery (ARCAPA) is a rare congenital coronary anomaly that is asymptomatic and discovered incidentally in most cases. ARCAPA is generally not considered a fatal defect in infancy or childhood, although cases of sudden death have been reported. Here, we report a 2-month-old female infant who presented with a prolonged fever that was determined to be caused by rhinovirus infection. Myocardial ischemia of the left ventricular posterior wall was already seen on echocardiography, and ARCAPA was discovered incidentally. The patient underwent successful surgical reimplantation of the right coronary artery to the aortic root to re-establish dual ostial circulation.

A case of a single coronary artery complicated with a coronary artery fistula (CAF) to the right ventricle is extremely rare, and its management strategy and prognosis are not clear. A 5-year-old boy was hospitalized for evaluation of a continuous heart murmur. Transthoracic echocardiography suggested a CAF to the right ventricle, with an enlarged left coronary artery. Cardiac catheterization confirmed the CAF terminating at the right ventricle and the absence of a right coronary artery. The fistula was ligated at the right ventricular side under cardiopulmonary bypass. At follow-up 18 months later, the child was clinically asymptomatic, and coronary angiogram showed no recurrence of the fistula.

The incidence of single coronary artery is extremely rare in a review of congenital anomalies of the coronary arteries. This 27-year-old male patient was referred for the evaluation of cardiac condition showing exertional dyspnea[NYHA class II-III] and chest discomfort for about 1 year. A complete catheterization study including angiogram disclosed large single coronary artery arising from left aortic sinus [Ogden classification L-4] associated with bicuspid aortic valvular stenosis and low grade supravalvular aortic stenosis. Calcified stenotic aortic valve was fully removed with caution and the 19mm St. Jude Medical valve was then implanted in the small nortic annulus. The patient had an uneventful recovery and was discharged on 13th postoperative day.
