Is the bicuspid valve opened or closed when the left atrium contracts?

Is the bicuspid valve opened or closed when the left atrium contracts?

Open: The bicuspid or mitral valve would be open when the left atrium contracts. It opens during diastole (heart is relaxed) and blood is flowing from the atrium to the ventricle. The contraction of the left atrium results in the valve opening wider and an increase in that flow. ...Read more

Valve (Definition)

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

Plz xplainEcho says EF 60% Mild mitral valve prolapse.Left Atrium mildly dilated.mild mitral regurg.cannot rule out bicuspid aortic valve considerTEE?

Had a cath?: The echo says there might be a structural abnormality of the aortic valve and a leak of the mitral valve with resultant dilation of left atrium. If you had the cardiac cath you list any time recently, more information should be available from that. A TEE is a transesophageal echo which gives us better pictures than a transthoracic echo. You should discuss this echo with your Doc ...Read more

I did echocardiography and the conclusion was minimal mitral valve and left atrium and tricuspid reflux with increased volume. What can it be?

I did echocardiography and the conclusion was minimal mitral valve and left atrium and tricuspid reflux with increased volume. What can it be?

Sizes?: Minimal mitral & tricuspid regurgitation is usually normal; however, the left atrial size should not be enlarged, and may be a clue to a different problem. It depends on the actual measurement of the atrial chamber size, in relation to your body size and related conditions. Further information, including reason for the echocardiogram, is needed. Call 911 if pass out, breathless, or chest pain. ...Read more

Question? Consult!: These little boxes are not good for answering specific patient case problems. Consider a cardiology consultation here on HealthTap. The kind of consult where you ask for help within the next 24 hours works particularly well for a complex case because it enables emailing back and forth with the details. ...Read more

What caused the left atrium to become mildly dialated?

What caused the left atrium to become mildly dialated?

Left atrial enlargem: Left atrium is the chamber the blood enters after flowing through the lungs. If its enlarged, there may be problems related to the pressure or volume of blood flow through the chamber. Many things can cause this, best to discuss with your doctor for your specifics. ...Read more

Why would the po2 in the aleolar capillaries be higher than po2 in the left atrium?

Why would the po2 in the aleolar capillaries be higher than po2 in the left atrium?

Oxygen: The po2 in the alveolar capillaries represents the just diffused oxygen from the alveoli, by the time the blood gets to the la there is some mixing of the blood with some blood that may have gone by poorly aerated alveoli and not got as much oxygen into it. ...Read more

How can the bicuspid and tricuspid valves open and close?

How can the bicuspid and tricuspid valves open and close?

Pressure gradients: The valve leaflets shown in the picture are very thin- like cloth. When the heart relaxes and pump, pressure gradients open and close the valves. I suggest you watch this video: http://www.youtube.com/watch?v=rguztY8aqpk ...Read more

Can anyone tell me what can happen to a person with a dilated left atrium?

Reason?: Depends on the reason? Do you have hypertension, mitral stenosis, mitral regurgitation, left ventricular hypertrophy, atrial fibrillation? These are all treatable. In all cases, you're at increased risk of developing atrial fibrillation and congestive heart failure. That doesn't mean you'll ever get those-your risk is simply increased. ...Read more
