Which Heart Valves Are Anchored By Chordae Tendinae To The Heart Muscle
The mitral &: Tricuspid.Get a more detailed answer ›
A valve is a structure that regulates the direction of flow. The heart is a special kind of pump. It moves blood by squeezing and relaxing. There are 4 chambers and each chamber has a valve. This keeps blood from moving backwards when the heart squeezes. When a chamber squeezes it lets the blood move forward but when the chamber is relaxed it prevents the blood from ...Read more
Chordae: The mitral and tricuspid have chordae. The mitral ones are those we discuss most. ...Read more

Can you explain how the heart valves opening/closing is synchronized with the heart's pacemaker firing?
One causes the other: The pacemaker of the heart initiates an electrical impulse that spreads across the upper chambers and causes them to contract. Contraction of the atria pushes the atrioventricular valves open. Subsequently, the electrical impulse is transmitted to the lower chambers of the heart. The contraction of the ventricles opens the semilunar valves; at the same time the atrioventricular valves close. ...Read moreSee 1 more doctor answer
No: Although a torn chordae tendinae can result from a heart attack, the two are not synonymous. Tearing of the chordae (part of the mitral valve apparatus) is more often related to other structural diseases of the mitral valve, like mitral valve prolapse and endocarditis (infection of the mitral valve) or chest trauma in some situations. Heart attack only rarely causes a torn chordae. ...Read more
4 locations: The first valve blood crosses is the tricuspid valve between the right atrium and right ventricle. Blood then flows across the pulmonic valve between the right ventricle and the lungs on its way to the lungs where it picks up oxygen and discards waste. It returns to the left atrium and crosses the mitral valve between the left atrium and left ventricle. It then exits across the aortic valve. ...Read moreSee 1 more doctor answer
Four heart valves: All 4 of your heart valves have three cusps. If you have a heart valve with 2 cusps that is a common congenital anomaly. A bicusp heart valve does not perform as well as a regular three cusp valve over a lifetime. Occasionally the bicusp valve will need repair or replace. The four valves are named; pulmonary, aortic, tricuspid and mitral. Be well. ...Read moreSee 2 more doctor answers
Heart valves: The mitral and aortic valves are the most often replaced valves, but sometimes the mitral valve can be repaired, but not the aortic valve. So probably the aortic is the most replaced. It is much less common that the pulmonary or tricuspid valve be replaced. ...Read more
Out: The heart muscle, specifically the ventricles contract or "pump". When the left ventricle contracts, propelling blood out of the heart, the aortic valve opens allowing blood to exit the heart. The blood travels from the heart in your great artery called the aorta. ...Read moreSee 3 more doctor answers
It is a body tissue that has the ability to contract. It shortens and generates force. It relaxes and returns to its original length. Muscles move joints, stabilize the body, move air and food through the organs, act as valves for bladder, bowel and other organs. They control movement of the eyes. They help us express ourselves by changing the shape of our ...Read more
