Tricuspid valve

“The heart valves work the same way as one-way valves in the plumbing of your home, preventing blood from flowing in the wrong direction” (ClevelandClinic). The tricuspid valve is the first one that the blood comes across as it arrives the heart. It stands between the right atrium and the right ventricle. The valve only permits the blood to flow from the atrium to the ventricle (Healthline). The pulmonary valve is at the opening from the right ventricle in the…

Ultrasound in Patients with Ebstein’s Anomaly Ebstein’s Anomaly of the tricuspid valve is a disease close to my heart, because I was diagnosed with it at birth and it has been a part of my life and a factor of inspiration toward the field of medical imaging. It has affected my health negatively, yet affected my life positively. I have seen every test and imaging modality involving this condition and its understanding. Ebstein’s anomaly is a congenital heart defect that counts for less than 1% of…

contract causing the tricuspid valve to open and for blood to pass through into the right ventricle. Then when the right ventricle is ready to contract the tricuspid…

blood goes through the tricuspid valve and into the right ventricle. The tricuspid valve then closes when the ventricles is full then the right ventricle contracts, sending the blood to the pulmonary artery. From the pulmonary artery the blood goes to the lung and get oxygenated. The oxygenated blood, then flows into the left atrium through the pulmonary vein. Then the mitral valve opens up and the blood goes into the left ventricle. When the left ventricle is full the mitral valve closes and…

versus postnatal circulation it is important to note that in a fully functioning not pregnant mammal blood circulates in the following way: vena cava, right atrium, tricuspid valve, right ventricle, pulmonary semi lunar valve, pulmonary arteries, lungs, pulmonary veins, left atrium, bicuspid valve, left ventricle, aortic semilunar valve, aorta, systemic circulation, vena cava. Fetal circulation works by using three shunts to direct deoxygenated blood and avoid the not yet fully developed…

The Mechanics of the Heart An electrocardiogram, or EKG/ ECG, is a non-invasive test that measures the electrical activity of the heart and its electrical patterns. An electrical signal is sent through the heart to produce contractions that move the blood. This is what an EKG measures. In total that test may take from five to ten minutes and are ordered by a doctor to examine the heart more close. An EKG is done while the patient is lying down completely still (in order to reduce artifact or…

filled, the right atrium contracts and pumps its contents into the right ventricle through the tricuspid valve. Once the right atrium is drained completely, the tricuspid valve will close to prevent blood from flowing back into the right atrium. Next, the right ventricle contracts, causing the pulmonary valve to open and forcing blood into the pulmonary artery. Once the blood is emptied, the pulmonary valve will close to prevent backflow. The deoxygenated blood will travel to the lungs through…

TASK 1 HEART The heart is a muscular organ that pumps blood throughout the body (Chiras, 2008). STRUCTURE The heart wall is composed of three layers of tissues: pericardium, myocardium and endocardium (Wilson, Waugh and Ross, 1996). Label structures of the heart for the diagram. Aorta is the major artery that carries oxygenated blood to the body. Pulmonary veins carry oxygenated blood from the lungs into the heart. Left atrium is one of the left upper chambers that takes oxygenated blood from…

vena cava 10, this blood enters the right atrium 11. Now the right atrium contracts pushing the blood into the right ventricle 1 through the tricuspid valve. As the ventricle is filled the tricuspid valve closes to prevent any back flow of the blood. The right ventricle contracts forcing the blood to enter into the pulmonary artery 2 through the pulmonary valve. The pulmonary artery extends into both of the lungs where the deoxygenated blood is replenished with oxygen and is send back to the…

Physiology Murmurs are the product of intense blood flow across inflexible, calcified valves; faulty valves that permit reverse blood flow (regurgitation); faulty (deviant openings) in the septum, aorta, or pulmonary artery; or abnormally high velocity of blood flow through a normal structure. Supposedly blood generally flows soundlessly through the heart; yet, these conditions can generate tumultuous blood flow resulting in auscultation of swooshing or gusty sound over the precordium (Weber &…
