and two inferior pumping chambers (ventricles). The atria receive blood from the veins returning blood to the heart. The ventricles eject blood from the heart in to arteries to be carried all over the body. Each anterior surface of the atrium has an auricle; each auricle slightly increases the capacity of the atrium so it can hold a greater volume of blood. The differences in structure of these chambers reflect the varying nature of their functions. The right atrium receives blood from the superior

The function of the right ventricle (RV) is to receive the systemic venous return and to pump this deoxygenated blood through the pulmonary arteries into the pulmonary circulation. The RV pumps the same amount of blood as the left volume pumps, this amount equals the stroke volume. The RV ejects blood against the pulmonary vascular resistance which is characterized by a low impedance and a highly distensible pulmonary arteries. On the other hand, the left ventricle (LV) ejects the blood against

inter-ventricular septum. Surface grooves indicate these divisions: the atria are separated from the ventricles by the coronary sulcus (the atrioventricular groove) with a hiatus anteriorly at the root of the pulmonary artery (PA). The atria are separated posteriorly by the inter-atrial groove though this is scarcely marked, and anteriorly this is hidden by the pulmonary artery and aorta. The ventricles are separated posteriorly by the posterior longitudinal sulcus on the diaphragmatic surface and anteriorly

and two ventricles. The right side of the heart receives deoxygenated blood and pumps the blood to the lungs, whereas the left side of the heart receives the oxygenated blood from the lungs and pumps it to the rest of the body. The right side of the heart consists of the right atrium and right ventricle. The right atrium receives the deoxygenated blood via the vena cava (both the inferior and superior) from the rest of the body. The blood then travels through the tricuspid valve into the right ventricle

able to withstand his insufficient tricuspid valve. Wilham’s autopsy of the young man indicated “an enlarged and fenestrated anterior tricuspid leaflet; the posterior and septal leaflets were hypoplastic, thickened and adherent to the right ventricle, an enlarged right atrium, and a patent foramen ovale” (Swiss Medical Weekly, 2005). Although Ebstein portrayed the first case it was not until 1927 that Alfred Arnstein suggested the name Ebstein’s Anomaly for these defects. Ten years later in 1937 Yates

Diagnosis and Treatment of Double Outlet Right Ventricle By Jonas Wilson, Ing. Med. Double outlet right ventricle (DORV) is a rare congenital disorder that has a yet to be identified cause and/ or predictive factor. Infants with DORV have great arteries (i.e. the aorta and pulmonary artery), which both arise from the right ventricle. This is in stark contrast to the normal anatomical left and right ventricle origin of the aorta and pulmonary artery, respectively. Infants may present in the

major bodily function. When there is heart failure occurring on the left side both the preceding and following regions of the heart will be affected. The left side of the heart is responsible for pumping blood systemically via the left ventricle. When the left ventricle fails this result in in inadequate amount of blood pumped systemically; in addition, since cardiac output has decreased, the blood will back up causing numerous other problems with the pulmonary system such as pulmonary arterial hypertension

Cardiac Hypertrophy/ “Athlete’s Heart” The body’s ability to adapt to changing conditions is a constant endeavor. Maintaining during intense change causes the body to adjust rapidly. The cardiovascular system’s ability to adapt during exercise has numerous adjustments to counteract the body’s newly acquired needs. The heart is capable of altering many functions such as stroke volume, heart rate, and cardiac output. In addition the heart can also undergo hypertrophy and increase in size. Cardiac
