Does Heart Depend On The Condition Of Aortic Valve In Regurgitation
Yes: The aortic valve(the valve that leads from the left ventricle to the rest of the body), if that valve leaks then the blood that was to go out to the body is coming back into the heart. A new batch of blood is entering in to the lv from the left atrium across the mitral valve , and this needs to go through the aortic valve to the rest of body. The lv has to work twice as hard and fails over time. ...Read more
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
Mitral location: Calling it a bicuspid mitral valve is redundant. The mitral valve has two (bi) leaflets and was named for its appearance similar to a bishop's miter. It is located between the left atrium and ventricle and its function is to prevent blood from flowing back into the left atrium when the left ventricle contracts and pumps its content into the aorta. ...Read moreSee 1 more doctor answer
What is the probability of stroke with both mitral valve regurgitation and stenosis of carotid artery?
Carotid v. Mitral : The carotid disease if stenosed (>80%) warrants surgical consideration as risk of stroke is increased. The mr, if miderate to severe, poses a risk for congestive heart failure not stroke. If not allergic or have issues with platelet function, daily Aspirin 81mg is recommended for atherosclerosis. ...Read more
Nice question!: Excellent - physiology at work! in subaortic stenosis, it is basically the muscular component of left ventricular outflow tract which is narrow. With increased preload - greater blood in lv - this stretches the muscle and allows for easier exit through the lvot and softer sound of murmur. ...Read more
It varies: Mild stenosis may casue no problems. Severe stenosis causes the pressure to increase in the left atrium, the lungs and eventually the right side of the heart. The left atrium enlarges in response to the higher pressure and the likelihood of atrial arrhythmias increases. Fluid can accumulate in the lungs causing shortness of breath and exercise intolerance. ...Read moreSee 1 more doctor answer
Mitral calcification: Under certain circumstances and with advanced age, the leaflets of the mitral valve can become loaded with calcium. This makes the leaflets stiffer and can limit the opening of the valve (mitral stenosis), causing a restriction of blood flow through the heart. There is another form of calcification in the mitral ring which usually does not cause any symptoms. ...Read moreSee 2 more doctor answers
Pulmonary HTN: You're correct. Mitral stenosis produces a diastolic rumble or murmur. However, as mitral stenosis worsens patients develop pulmonary hypertension. This in turn will increase the pressure in the right ventricle which could induce a normal tricuspid valve to leak. This murmur would be systolic. ...Read moreSee 1 more doctor answer
Mitral valve: The mitral valve has to open properly to let blood flow into the left ventricle from the atrium. If it doesn't, we call this stenosis. It has to close to keep the blood flowing toward the body, if it doesn't we call this regurgitation or insufficiency. Either or both problems can exist with the valve if its abnormal. Insufficiency is more common. ...Read moreSee 1 more doctor answer
You mean malfunction: The aortic valve has 3 parts or leaflets. When its called bicuspid it has only 2 leaflets. This can be congenital or aquired. If two of the cusps fuse over time is called functional bicuspid vs congenital. Either way it creates an un natural flow across the valve and over time damage the valve. Most often the valve will need replace depending on age diagnosed.Most congen bicuspids will need repla. ...Read moreSee 1 more doctor answer
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
Lots: I'm not sure what exactly you're referring to, but the typical valve with two leaflets is the mitral valve. It's usually not called "the bicuspid valve" though. A bicuspid aortic valve is a 2 leaflet aortic valve (should be 3) and is the most common congenital abnormality which can lead to aortic valve leaking or tightness later in life. ...Read moreSee 1 more doctor answer
How serious is subaortic vsd (1.1 cm)? The mitral and tricuspid valves show redundant leaflets with evidences of prolapse and the left ventricle is slightly dilated.
Aortic Valve: The aortic valve is an integral part of the heart and is located between the left ventricle and the aorta. It opens when the left ventricle contracts (systole) and allows blood to be pumped into the aorta. It closes when the left ventricle fills (diastole). It's function is to prevent blood from flowing back from the aorta while the heart is filling. ...Read moreSee 1 more doctor answer
Echo shows Calcification of aortic valve & thickened mitral valve, BP stays 140/100 or higher. Short of breath and fatigue. What could be the cause?
Stenosis : Blood will have trouble going between heart chambers and great vessels. Depending on the chronicity and the degree of stenosis, bad damage can happen to your lung circulation and your heart chambers. Consequences can be catastrophic. Heart attacks, syncope, heart failure, arrhthmias, sudden death. Common causes are uncontrol htn, congenital bicuspid aortic valve, infections/iv street drugs etc. ...Read moreSee 1 more doctor answer
Mitral stenosis: Mitral stenosis is a narrowing of the mitral valve caused by rheumatic fever. Progressive narrowing of the mitral valve can cause heart rhythm disturbances and the development of heart failure symptoms. This condition can be corrected with either mitral balloon valvuloplasty or surgery. ...Read moreSee 1 more doctor answer
The aortic valve is one of 4 valves in the heart, each of which separates 2 cardiac chambers. It opens when blood is actively ejected from the left ventricle into the aorta artery, to be carried to the rest of the body. It then closes firmly to prevent blood from flowing backwards, while it passively continues to flow forward to body's vital organs. When next heartbeat ...Read more
