MedlinePlus Medical Encyclopedia: Right heart ventriculography Right heart vetriculography is a study of the right chambers (atrium and ventricle) of the heart. This is obtained by injection of contrast media through the catheter into the right side of the heart with a rapid succession of x-rays taken to capture images of blood flow. Abnormal pressures or volumes, abnormalities of the right-sided heart valves, and abnormal connections between the right and left side of the heart may be detected. www.nlm.nih.gov /medlineplus/ency/article/003874.htm   (615 words)

Cardiac-Disease.net: Information on the diseases of the heart and heart valves   (Site not responding. Last check: 2007-10-08) The causes of right heart failure are left heart failure, obstructive lung disease, and congenital heart defects. Infections of the pericardium or endocardium of the heart may be caused by a variety of organisms including bacteria, fungi, rickettsiae, and sometimes viruses or parasites. When it equals or exceeds that of the heart during diastole, structures such as the right atrium and ventricle become compressed and blood is not returned to the heart. www.cardiac-disease.net   (1951 words)

Open Heart   (Site not responding. Last check: 2007-10-08) The right side of the heart, made up of the right atrium and the right ventricle (often called the "right heart" by doctors) pumps blood through our lungs, where it receives oxygen and rids itself of carbon dioxide. The right side of the heart is responsible for pumping blood to the lungs (pulmonary circulation). The left side of the heart is responsible for pumping blood to the tissues and organs of the body to deliver oxygen from the lungs. www.open-heart.net /print.php?sid=65   (450 words)

THE MERCK MANUAL, Sec. 19, Ch. 261, Congenital Anomalies Heart murmurs and thrills due to turbulent flow within the heart or great vessels are most prominent at the surface closest to their point of origin, making localization diagnostically helpful. Heart murmurs vary and may include a flow murmur at the base, a loud regurgitant murmur at the lower left sternal border, and a mid-diastolic mitral flow murmur. Treatment is needed for heart failure, and early surgical repair is indicated using a valved conduit between the right ventricle and the pulmonary arteries that are being surgically removed from the truncus arteriosus. www.merck.com /pubs/mmanual/section19/chapter261/261b.htm   (4526 words)

what is heart failure?   (Site not responding. Last check: 2007-10-08) Heart Failure is a condition initiated by impairment of the heart's function as a pump! Heart failure is a progressive disorder in which damage to the heart causes weakening of the cardiovascular system. Heart failure is a cumulative consequence of all insults to the heart over someone's life. www.heartfailure.org /eng_site/hf.htm   (547 words)

Overview of the Human Heart   (Site not responding. Last check: 2007-10-08) Perversely,the base of the heart is the uppermost part of the heart, it tilts slightly backwards (towards the spinal column) and from it emerge two of the great vessels, the aorta and the pulmonary trunk; the superior vena cava and inferior vena cava enter its right side (see diagram 1 above). The heart is held in place principally by its attachment to the great arteries and veins, and by its confinement in the pericardium, a double-walled sac with one layer enveloping the heart and the other attached to the breastbone, the Within the adult heart are two parallel independent systems, each consisting of an auricle, or atrium, and a ventricle; from their anatomical positions these systems are often designated the right heart and the left heart. www.jdaross.mcmail.com /heart1.htm   (592 words)

chambers   (Site not responding. Last check: 2007-10-08) The activity is designed to teach students how the heart pumps blood in to the right atrium from the body. The right side is playing against the left side of the heart. For example, if you were in the right atrium, you would go through the valve to the right ventricle. www.oswego.org /staff/dlavner/web/chambers.htm   (420 words)

Valvular Heart Disease in Dogs - WSAVA 2002 Mean left atrial pressure is dependent on: (1) the volume of regurgitant flow; (2) the output of the right heart; (3) left ventricular diastolic pressure; and (4) the compliance of the left atrium. Moderate to severe heart failure in dogs with experimentally created or naturally occurring mitral regurgitation is accompanied by increased sympathetic nervous system activity and activation of the renin-angiotensin-aldosterone (R-A-A) system.Diuretic treatment further intensifies the activity of the R-A-A system. As left-sided congestive heart failure develops, the evaluation of good quality radiographs permits the visualization of early changes in the pulmonary veins and the interstitium of the lung. www.vin.com /proceedings/Proceedings.plx?CID=WSAVA2002&PID=2532&Category=408   (2043 words)

Welcome to Thic - Hypoplastic Right Heart Syndrome Hypoplastic right heart syndrome (HRHS) refers to underdevelopment of the right sided structures of the heart. Secondary problems include a very small (hypoplastic) right ventricle (lower chamber which normally pumps blood to the lungs); a small tricuspid valve (this valve allows blood to flow into the right ventricle) and a small (hypoplastic) pulmonary artery. Because the blue blood cannot pass through the right side of the heart to get to the lungs, it crosses into the left atrium and mixes with red blood returning from the lungs. www.thic.com /hyporight.htm   (255 words)

Healthopedia.com - Swan-Ganz Catheterization (Right Heart Catheterization, Catheterization, Right Heart) During the Swan-Ganz catheterization, a thin flexible tube is inserted into the right side of the heart to measure and monitor its functions. Once in the heart, the catheter is passed through the right atrium and the right ventricle. Heart function during the procedure is monitored by electrocardiography (EKG), a recording of the electrical activity of the heart. www.healthopedia.com /swan-ganz-catheterization   (406 words)

Re: enlarged heart The hearts of athletes are often enlarged in a completely healthy way because of the extra demands of exercise. This is a self defeating strategy though, because the enlarged heart usually works less efficiently and has to enlarge further and work even harder until eventually you end up with heart failure or the propsensity for fatal arrythmias. As soon as the attack is over and their breathing returns to normal, so too the evidence of right heart strain disappears. www.diagnosishealth.com /discussion1/_disc79/000001fa.htm   (173 words)

Congenital Heart Disease Left to Right shunting (L->R) results when an intracardiac or extracardiac communication between the two sides of the heart persists after birth and left-sided pressures exceed right-sided pressures (the typical situation). The shunting reflects higher right sided pressures compared to the left and the degree of cyanosis reflects shunt volume. When there is obstruction to blood through the heart, (ie., aortic or pulmonic stenosis or coarctation), concentric ventricular hypertrophy predominates with little dilitation. www.concentric.net /~Drphilxr/heartpk1.htm   (3709 words)

hlhsinfo Hypoplastic Left Heart Syndrome (HLHS) is a condition in which the left side of the heart is underdeveloped. The heart is comprised of four chambers: the upper chambers are called the left and right atria, and the lower chambers are called the left and right ventricles. Very simply, in a healthy heart blood flows from the right atrium to the right ventricle where it is then pumped through the pulmonary artery to the lungs to be oxygenated. www.hlhsinfo.homestead.com   (1304 words)

HEART DISEASE Recognize that in congenital heart disease with impaired blood flow to the lungs, it is good for the ductus to remain open. Either the heart muscle cannot pump because of intrinsic disease, or the blood is flowing in the wrong way, or the heart must pump against excessive resistance, or the heart must pump a preposterously large amount of blood (the latter is "high output failure"). Heart J. The typical patient has a slim build (the more "Marfanoid" you are, the most likely you are to have "Barlow's"), a mid-systolic click (the leaflet snapping tight) and ever-so-slight mitral regurgitation. www.pathguy.com /lectures/heart.htm   (11883 words)
