“…4 We did not observe a large conal branch in any of the study group either by angiography or echocardiography. A large conal branch could be distinguished from an aberrant anterior descending artery by tracing its termination to the right ventricular infundibulum rather than down the interventricular sulcus.…”

“…The types of anomalies were similar to those reported in other series. [2][3][4][5][6][7] High left parasternal images proved to be the most sensitive for detection of an abnormal coronary artery crossing the right ventricular outflow tract. Apical and subcostal windows allowed visualization of the coronary arteries in some patients, but relations were more difficult to ascertain.…”

Evaluation of coronary artery anatomy in patients with tetralogy of Fallot by two-dimensional echocardiography.

A major coronary artery crossing the right ventricular outflow tract in patients with tetralogy of Fallot interferes with a transannular patch, and preoperative detection of this artery is important. We evaluated the ability of two-dimensional echocardiography to define noninvasively the coronary artery anatomy in 37 consecutive patients (age range, 1 day to 18 years; mean age, 40.9 months). The origin and distribution of the right anterior descending and circumflex coronary arteries, as well as any anteriorly coursing vessel, were examined from parasternal views. Complete studies were obtained in 29 (78%) of the 37 patients. Coronary artery anatomy was determined to be normal by echocardiography in 20 (69%) of the 29 patients. An anterior vessel across the right ventricular outflow tract was detected in the remaining nine patients. Six patients had an anterior descending artery from the left main coronary artery (paired anterior descending arteries in three patients, a right anterior descending artery from the left main coronary artery in two patients, and a right coronary-topulmonary artery fistula in one patient). Three patients had no anterior descending artery from the left main coronary artery (anterior descending artery from the right main coronary artery in two patients, and anterior descending and circumflex arteries from the right main coronary artery in one patient). Angiography, surgery, or autopsy confirmed the diagnoses in all but the final patient in whom the anterior descending artery arose from the right main coronary artery as observed at surgery, but the circumflex artery was not seen. Accurate evaluation of coronary artery anatomy is possible by echocardiography in the majority of patients with tetralogy of Fallot. Noninvasive identification of a major coronary artery coursing anteriorly can influence the timing of cardiac catheterization and surgery and the need for angiography. (Circulation 1988;78:149-156)

The recent increase in incidence of Kawasaki disease with attendant coronary artery aneurysms spurred our interest in developing a technique for selective coronary arteriographic examination of infants and children. Right and left coronary artery catheters were shaped according to the aortic root diameters and ascending aorta lengths predicted from the patient's heights. Thirty-eight studies were done in 34 patients who were 7 months to 18 years of age (median 3.2 years) and no permanent sequelae resulted. Advantages of the use of selective coronary arteriography include the ability to visualize stenoses, important branches, and intercoronary anastomoses. The technique is also useful in evaluation of anomalous coronary arteries, myocardial ischemia, and coronary artery distribution before right ventricular outflow tract reconstruction. Circulation 68, No. 5, 1021No. 5, -1028No. 5, , 1983 Arteriographic examination was performed after the child's fever subsided and erythrocyte sedimentation rate returned to normal. Although coronary artery bypass surgery has been done in relatively few patients with Kawasaki disease in Japan and the United States, the potential need for such an operation does exist in the event that antithrombotic drug therapy is not initiated in a timely manner or is discontinued prematurely, resulting in myocardial ischemia or infarction. Such surgical interventions are predicated on detailed infonnation about coronary artery anatomy and flow pattern.Indications for coronary arteriography in patients with congenital heart disease.

“…Less often, the coronary artery is single, or the right coronary artery originates from the circumflex coronary artery [5]. In another variation, the septal coronary arteries originate from the left and right coronary arteries [6]. The alternative procedure reported in these two cases is similar to a technique that has been previously described [1,4].…”
