Atrioventricular Valve And Similunar Valves
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
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
HCM: Not sure what you're asking. Hypertrophic obstructive cardiomyopathy in series with a bicuspid aortic valve has a potential for real trouble if the bicuspid becomes stenotic. If the bicuspid valve isn't stenotic, then the physiology is dictated by the ihss primarily. ...Read moreSee 1 more doctor answer
HEART The mitral valve leaflets appeared thickened,there is a trace of tricuspid regurgitation & pulmonic valvular regurgitation. What does that mean?
Mitral regurgitation: Mr murmur is an early systolic, holosystolic, or also referred to as blowing systolic murmur best heard over the apex radiating to the left axilla. Aortic stenosis is an ejection systolic murmur best heard over the right upper stern all border, radiating to the neck, and there may be an ejection systolic click heard over same area and apex. ...Read moreSee 1 more doctor answer
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
Valve replacement: The surgery replaces the valve with either a mechanical or animal tissue valve. This is done on a heart lung machine. The valve takes the place of the damaged valve and the patient lives their life with a new disease 'artificial valve' with its own set of problems. The obstruction or valve leak of the diseased valve is corrected by the artificial valve. Sometimes blood thinners are needed. ...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
Multiple: The pitch is different. Also, each is better heard in a different location in the chest, and the duration of the murmur during the cardiac cycle are different. ...Read more
Summary of my resent echogram;
1-Low normal left ventricular function. Ejection fraction is est.52%
2-Mild left atrial enlargement.
3-Mild to moderate aortic valve regurgition.
4-Moderate aortic valve stenosis.
5-Mild tricuspid valve regurgitation.
Need cardiologist!: There are a number of concerning findings on your echocardiogram. The left ventricular function (how strong your pump is) is just a little low; I'm not that concerned about that. The valves, especially aortic, are the biggest problem: to have both aortic regurgitation (back flow across the valve) and narrowing (stenosis) is very concerning. Follow up soon with your cardiologist. Good wishes:) ...Read more
Can both tricuspid valve stenosis and tricuspid regurgitation result in hypertrophy in the right atrium?
Sort of: The right atrium tends to enlarge somewhat with both conditions; it is more so with tricuspid stenosis. Technically though it is an enlargement, not a hypertrophy (which means muscular thickening). Ra enlargement with tr would imply either severe tr or very elevated pulmonary resistance pressures. ...Read more
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.
Different structure: The aortic and pulmonic valves are the ventricular outlet valves. Their shape is different form the ventricular inlet valves. The are a more solid structure with 3 leaflets that close after systole. If you look at google images of the aortic valve and the mitral valve you can see the difference. ...Read more
NO.: Aortic valve replacement in a patient with a bicuspid aortic valve may require repair of an ascending aortic aneurysm if present. Although valves are sewn in place the same, the location is totally different with particular anatomic differences. The mitral closes in systole and the aortic valve in diastole. For the mitral need to actually open the heart. For the aortic its done thru the aorta. ...Read more
Why does the right atrioventricular valve have three cusps while the left atrioventricular valve has only two cusps?
Because: because that's the way we evolved. Or, if you'd prefer, that's what God intended. Either way it comes down to tautology: it is what it is, man. ...Read more
Please explain why the right atrioventricular valve has three cusps while the left atrioventricular valve has only two cusps?
Excellent question: And there's no answer for it except to say (as unsatisfying as it may sound), "that's how god made us.". ...Read more
Is the valve regurgitation that is caused by atrioventicular septal defect (mr or tr) seen in doppler echo?
4: 4 cardiac valves. 2 atrioventricular and 2 ventriculoarterial. 2 on the right heart 2 on the left heart. Each ventricle has an atrioventricular and a ventriculoarterial valve.They are one way valves. Flow is venae cavae to right atrium, RA to right ventricle via right av valve or tricuspid, rv to pulmonaryartery via pulmonic valve-lungs-left atrium-mitral valve-left ventricle-aortic valve- aorta. ...Read more
May be normal: The aortic valve is comprised of three leaflets, or cusps, that swing open and closed. Approximately 1% of the population is born with only 2 cups. These swing open and shut in a similar fashion. Depending on the precise architecture of the 2 cusps, there may be increased turbulence of blood flow through the valve, and over time more wear and tear leading to thickening/obstruction, or leaks. ...Read moreSee 1 more doctor answer

Not enough info: Without knowing what is wrong with your mitral valve, it is impossible to say. You need to go see a cardiologist and discuss your cardiac echo (ultrasound that looked at your mitral valve). Ask for a list of exactly what you can and cannot do to keep yourself healthy - don't wait. ...Read more
One of 4 heart valve: The mitral valve is one of the 4 heart valves found in the heart. These valves keep blood moving one direction rather than back and forth as the heart contracts. The mitral valve is so named as it looks like the pope's hat (a mitre). The mitral valve separates the left atrium and the left ventricle. ...Read moreSee 1 more doctor answer
