	eMedicine - Atrial Septal Defect, Coronary Sinus : Article Excerpt by: Louis I Bezold, MD
		Background: Coronary sinus atrial septal defects (ASDs) are defects located in the portion of the atrial septum that includes the coronary sinus orifice, and they are characterized by the absence of at least a portion of the common wall separating the coronary sinus and the left atrium.
		Coronary sinus ASDs are believed to arise from developmental failure of formation of the wall between the coronary sinus and the left atrium.
		The coronary sinus is a systemic venous structure embryologically derived primarily from the left common cardinal vein that is continuous with the left anterior cardinal vein.

	Atrial
		The sinus venosus defect occurs as a result of deficient tissue along the remnant of the right horn of the sinus venosus, which extends from the orifice of the superior vena cava to the orifice of the inferior vena cava.
		Coronary sinus defects occur as a result of a deficiency in the remnant of the left horn of the sinus venosus, which extends along the entire length of the coronary sinus.
		The opening of the coronary sinus is usually present in the usual location, however, the wall between the coronary sinus and the left atrium is variably deficient.

	Coronary Arteries
		The epicardial coronary artery system consists of the left and right coronary arteries, which normally arise from ostia located in the left and right sinuses of Valsalva, respectively (see figures 104c, 104d, 104e, 104f, 104h).
		The natural history of coronary fistulas is variable,with periods of stability in some and sudden onset or gradual progression of symptoms in others.Spontaneous closure is uncommon.
		A large coronary arteriovenous fistula can be seen originating in the left coronary artery, coursing over the lateral and posterior walls of the left ventricle, and eventually emptying into the right atrium.

	Coronary sinus catheter - Patent 4927412
		In general, the coronary sinus catheter is comprised of a flexible elongate member having at least two lumens extending longitudinally thereof.
		The cardioplegia catheter is intended to be placed in the coronary sinus of the patient during open heart surgery and is intended to provide nutrient solutions to the myocardium to support the heart muscle during the time that the operation is taking place when the heart is not beating, that is, during cardioplegia.
		It has been found that the particular shape of the balloon with the lands thereon adapts the balloon for engaging the tissue forming the sinus so that the balloon is retained within the sinus with a high retentive force which cannot be readily dislodged and therefore serves to maintain the catheter in the desired position.

	Anomalous orgin of a coronary ostia from the right sinus of Valsalva in a patient with hypertrophic cardiomyopathy ...
		The superior left ostium gave rise to a coronary artery supplying the anterolateral wall of the left ventricle; this artery was designated arbitrarily as a ramus branch, and it supplied the portion of the left ventricle typically supplied by a first obtuse marginal or ramus intermedius.
		The causes of death in these cases3 were hypertensive atherosclerotic coronary artery disease in a 64year-old and complications of a motor vehicle accident in a 62-year-old with cardiomegaly due to hypertensive heart disease.
		In addition, sudden death secondary to anomalous origin of the coronary arteries is rare after the age of 40,4 there was no artery coursing between the aorta and the pulmonary artery, and there was no demonstrable necrosis or scarring in the ventricular myocardium to suggest prior episodes of ischemia.

	Repair Of Coronary Sinus Rupture Secondary To Internal Cardiac Massage
		This is the first report of coronary sinus injury secondary to internal cardiac massage.
		The hematoma had obscured the tissue planes and it was not possible to discern clearly the edges of the defect in the coronary sinus all round (Figure 1).
		A ruptured coronary sinus is very difficult to repair primarily as the edges are not clearly seen and the hematoma causes obliteration of normal tissue planes.

	Echocardiography
		Patients with anomalous left main coronary artery arising from the right sinus of Valsalva and coursing posteriorly between the aorta and the pulmonary artery are prone to sudden death.
		Twenty of the 27 p atients with an intramural coronary artery were correctly diagnosed prospectively by echocardiography (sensitivity, 75%), including 17 of 23 patients with an intramural left coronary artery or left anterior descending coronary artery and 3 of 4 patients w ith an intramural right coronary artery.
		Two primary diagnostic criteria were identified: a major coronary artery arising from the contralateral septal sinus, near the usually intercoronary commissure, and a course for this vessel within the posterior aor tic wall between the great arteries, creating a "double-border" appearance.

	The thorax
		The Coronary Valve is a semicircular fold of the lining membrane of the auricle, protecting the orifice of the coronary sinus.
		The sinus is cuboidal in form, and concealed in front by the pulmonary artery and aorta; internally, it is separated from the right auricle by the septum auricu-larum; and behind, it receives on each side the pulmonary veins, being free in the rest of its extent.
		The annular fibres surround the whole extent of the appendices auriculas, and are continued upon the walls of the venae cavas and coronary sinus on the right side, and upon the pulmonary veins on the left side, at their connection with the heart.

		Sinus bradycardia or junctional rhythm and atrioventricular block are reported in association with unrepaired secundum ASDs.
		Coronary sinus ASDs may be observed in association with complex forms of congenital heart disease, most often in association with abnormalities of atrial situs and heterotaxy syndromes with polysplenia or asplenia.
		The surgical treatment of isolated coronary sinus ASD is complicated by its proximity to the atrioventricular node.

	The coronary circulation in human septic shock.
		To determine whether myocardial depression in human septic shock is associated with reduced coronary flow, thermodilution coronary sinus catheters were placed in seven patients with septic shock for measurements of coronary flow and myocardial metabolism.
		In general, compared with values in control subjects, the oxygen content difference (arterial minus coronary sinus) was narrowed, and the fractional extraction of arterial oxygen was diminished.
		The preservation of coronary flow, the net myocardial lactate extraction, and the increased availability of oxygen to the myocardium argue against global ischemia as the cause of myocardial depression in human septic shock.

	Coronary sinus approach for repair of mitral valve regurgitation patent invention
		Some of these devices attempt to correct mitral valve regurgitation by placing a compressive force on the coronary sinus that then compresses at least a portion of the mitral valve annulus adjacent the coronary sinus.
		Still other devices that are implanted in the coronary sinus attempt to decrease valve regurgitation by straightening the radius of the coronary sinus.
		Straightening the coronary sinus results in a corresponding straightening of a portion of the mitral valve annulus adjacent the straightened coronary sinus.

	Circulation of the Heart (Site not responding. Last check: 2007-10-17)
		The arteries that supply the heart are coronary arteries; the veins of the heart are known as the cardiac veins.
		The right coronary artery originates from the right aortic sinus and passes to the right, behind the pulmonary trunk, to run downward in the coronary sulcus between the right atrium and the right ventricle.
		The posterior vein of the left ventricle drains the diaphragmatic surface of the ventricle and enters the coronary sinus soon after the sinus is formed.

	The Journal of Invasive Cardiology - Coronary Anomalies
		An anomalous left coronary artery originating from the pulmonary artery (ALCAPA) is a rare congenital coronary abnormality often associated with myocardial infarction, congestive heart failure and sudden death.
		Single coronary artery anomaly, with the left main artery originating from the proximal right coronary artery, can be responsible for myocardial blood supply insufficiency and causes chest pain or sudden death, especially during physical exercise, as it courses between the aorta and the pulmonary artery.
		Anomalous origin of coronary arteries is discovered incidentally during coronary arteriography or at autopsy, and awareness among angiographers is required.

		When the vessel reaches the coronary groove it crosses the circumflex branch of the left coronary artery and opens into the coronary sinus at the level of the left azygos vein and coronary sinus junction (5).
