The heart is the driving force in humans and other animals, circulating blood and oxygen through the body. It is a muscular organ located in the chest cavity between left and right lungs. The heart pumps blood to all parts of our bodies through a network of arteries and veins called the cardiovascular system.
The heart is a muscular organ about the size of a closed fist that functions as the body’s circulatory pump. In humans, the heart is approximately the size of a large fist and is located between the lungs, in the middle compartment of the chest.
It has three semilunar cusps or leaflets. The leaflets open when blood pumps out of the right ventricle, allowing it to flow into the pulmonary artery and on to the lungs. If one or more of the leaflets become narrowed, stiffened, damaged or deformed, a condition called pulmonary valve stenosis may develop.Mitral valve: The mitral valve is located between the left atrium and left ventricle.
The pulmonary valve is a semilunar valve located between the right ventricle and the pulmonary artery. It has three semi-lunar cusps and regulates blood flow from the right ventricle to the pulmonary artery, which carries blood to the lungs.
The mitral valve is the valve between the left upper and lower chambers (left atrium and left ventricle) of the heart. It has two flaps (leaflets or cusps) that open and close with each heartbeat, allowing blood to flow in one direction through the heart.
The aortic valve separates the left ventricle and the systemic aorta (the largest artery in the body). It regulates the flow of blood from the heart to the rest of the body. The aortic valve has three cusps or leaflets that open and close due to pressure changes within the heart. … The pressure generated by contraction of the ventricles forces blood out through the aortic valve.
Valves are a set of four flexible flaps (called leaflets), which sit at the entrance and exit of each heart chamber. A healthy valve closes tightly to prevent blood from flowing backwards – this is called regurgitation. A healthy valve allows blood to leave the heart smoothly without excessive turbulence – this is called flow.
If the valve does not open properly, it is known as stenosis. If it does not close completely, then it is known as an insufficiency. In such a case the valve needs to be repaired or replaced. Therefore, the valve replacement surgery cost in India is higher than most surgeries.
Valve stenosis describes narrowing of the heart’s valves. When blood flow is restricted in this way, it makes it harder for the heart to pump blood through the body. This causes the heart to work harder and can lead to congestive heart failure. Call your doctor if you experience chest pain, shortness of breath, light-headedness, dizziness or fainting during exercise, a rapid or irregular pulse or swelling in the feet, ankles, legs and abdomen.
A doctor may consider replacing a valve if it doesn’t open enough to permit normal blood flow (stenosis) or if the valve doesn’t close tightly enough and lets blood leak through when it shouldn’t (regurgitation). Heart valve replacement surgery is an open-heart surgical procedure during which a surgeon removes a damaged or diseased heart valve and replaces it with an artificial valve. This artificial valve can be made of animal tissue, metal, or synthetic material.
Valve regurgitation or backflow of blood happens when a heart valve is not closing properly. The flow of blood backwards through the mitral and tricuspid valves in the heart causes a murmur that doctors can detect with a stethoscope. A leaky valve may also cause shortness of breath, fatigue, and low blood pressure, especially after physical activity.
Congenital valve disease means a congenital heart defect (CHD) that involves one or more of the valves of the heart. Valve disease can involve stenosis (narrowing) or insufficiency (leakage). The defects are either congenital (present at birth) or acquired.
A bicuspid aortic valve sometimes makes a sound that can be heard with a stethoscope when the physician listens to your heart. The sound is called a murmur. You may not have any symptoms for years, or you might develop shortness of breath or chest pain in childhood or early adulthood. With this condition, you may have an increased risk for infection of the heart valves (endocarditis).
Acquired valve disease is a type of heart valve disease. It includes several conditions that affect your valves, the flaps that open and close to help the blood flow in one direction through your heart. One type of acquired valve disease is endocarditis. Endocarditis is an infection of the valves or inner lining of your heart.
