		It is represented subsequently by the attachment of the arterial ligament to the underside of the arch.
		There are two major coronary arterial branches from the aorta which arise from two of the three sinuses of Valsalva, permitting the sinuses to be named as right coronary and left coronary, respectively.
		When supplying the posterior artery, the right coronary artery itself makes a U-turn into the area of the atrioventricular muscular septum and gives off the artery to the atrioventricular node from the apex of the U. It then continues on to the diaphragmatic surface of the left ventricle where it supplies ventricular branches.

	Congenital Heart Disease
		Congenital heart disease is a type of defect or malformation in one or more structures of the heart or blood vessels that occurs before birth.
		Congenital heart disease is often first detected when your doctor hears an abnormal heart sound or heart murmur when listening to your heart.
		Most adults with congenital heart disease should be monitored by a heart specialist and take precautions to prevent endocarditis (a serious infection of the heart valves) throughout their life.

	ADULT CONGENITAL HEART DISEASE GLOSSARY
		The operation involves anastomosis of the proximal end of the transected main pulmonary artery in an end-to-side fashion to the ascending aorta to provide blood flow from the systemic ventricle to the aorta; coronary arteries are not translocated and are perfused in a retrograde fashion.
		Both the pulmonary artery and the aorta arise predominantly from the morphologic left ventricle.
		Congenital heart defects are frequent, atrioventricular septal defect and ventricular septal defect being the most common.

	Coronary artery bypass surgery
		Coronary bypass surgery is a common procedure used to divert blood around blocked arteries in the heart.
		Coronary bypass surgery uses a healthy blood vessel harvested from your leg, arm, chest or abdomen and connects it to the other arteries in your heart so that blood is bypassed around the diseased or blocked area.
		Another risk of coronary bypass surgery is that plaques — the fatty deposits that accumulate on the inner walls of coronary arteries and other vessels in atherosclerosis — may break loose from the walls of the aorta when it's clamped shut for the heart-lung machine.

	THE MERCK MANUAL, Sec. 19, Ch. 261, Congenital Anomalies
		Conduit repair of truncus arteriosus is sometimes possible, removing the pulmonary artery from the truncus and inserting a valved conduit to direct blood from the right ventricle to the pulmonary arterial tree.
		However, in children with certain conditions (eg, congenital rubella, hypercalcemia syndrome [Williams syndrome]) and in some otherwise normal children, flow to branch pulmonary arteries is anatomically obstructed and may produce a continuous murmur.
		Less common abnormalities (eg, Ebstein's malformation of the tricuspid valve), evidence of cardiac involvement with fetal disease (eg, prolonged in utero anemia, fetal dysrhythmia), severe cardiac anomalies associated with asplenia syndrome, and cardiac dysfunction secondary to noncardiac disease (eg, hypothyroidism) require individualized management.

	Congenital Cardiovascular Defects
		Congenital means inborn or existing at birth. Among the terms you may hear are congenital heart defect, congenital heart disease and congenital cardiovascular disease. The word "defect" is more accurate than "disease." A congenital cardiovascular defect occurs when the heart or blood vessels near the heart don't develop normally before birth.
		Congenital cardiovascular defects are present in about 1 percent of live births.
		Some congenital cardiovascular defects let blood flow between the heart's right and left chambers. This happens when a baby is born with an opening between the wall (septum) that separates the right and left sides of the heart.

	Total Anomalous Pulmonary Venous Return, Cincinnati Children's Hospital Medical Center (Site not responding. Last check: 2007-10-31)
		Total Anomalous Pulmonary Venous Return (TAPVR) is a rare congenital malformation in which all four pulmonary veins do not connect normally to the left atrium, but instead drain abnormally to the right atrium by way of an abnormal (anomalous) connection.
		The coronary sinus is the vein that normally returns blood from the heart muscle itself back to the right atrium after its oxygen has been depleted.
		Because this blood is a mixture of oxygenated and unoxygenated blood, the overall content in the blood ejected by the left ventricle to the aorta is decreased.

	Coronary angioplasty and stenting: Opening clogged arteries
		Coronary angioplasty is a medical procedure used to open arteries that have narrowed to the point that they impede blood flow to the heart.
		Once the artery is widened, a device called a stent is usually placed in the artery to act as scaffolding to help prevent it from renarrowing after the angioplasty.
		In that procedure, an artery or a vein is removed from a different part of your body and sewn to the surface of your heart to take over for the blocked coronary artery.

	eMedicine - Ebstein Malformation: Surgical Perspective : Article by Mark Plunkett, MD
		In Ebstein malformation, the insertions of the septal and posterior leaflets are displaced to the junction of the inlet and trabecular portions of the right ventricle, indicating abnormal delamination (Anderson, 1979).
		The coronary arteries are normal in distribution, and the right coronary artery is often displaced by the enlarged right atrium and atrialized right ventricle.
		Arterial blood gas levels determine the severity of cyanosis and indicate the amount of right-to-left shunting at the atrial septal defect.

		TGA is a heart malformation which occurs in approximately 5% of patients with congenital heart disease.

		In the child who had anomalous origin of the right coronary artery from the pulmonary artery, enlargement of the APW was performed to allow for placement of the bovine pericardium patch in a position to set the right coronary artery connected to the aorta.
		The right coronary artery is the one most frequently involved (7 cases), followed by the left coronary artery (5 cases), single ostium coronary artery (2 cases) and both coronary arteries (1 case).
		Because it is a rare congenital heart disease (<1%) and does not have specific semiologic characteristics, APW should be considered in the differential diagnosis of children presenting with early heart failure, especially in the presence of nonspecific mitral regurgitation.
