Why can?You ?Hear?The diastolic murmur of mitral stenosis better in the expiration?

Why can?You ?Hear?The diastolic murmur of mitral stenosis better in the expiration?

Changes in intrathor: Inspiration leads to a more filling of the atrium; thus, more blood must flow through the mitral valve, enhancing the flow rate which makes the murmur louder. ...Read more

Heart Murmur (Definition)

A heart murmur is a sound heard by a stethoscope made by the vibration of blood flow. It can be a normal finding in young healthy people, or can represent abnormal leakage (regurgitation) of a valve, valve narrowing (stenosis), or a congenital condition such as an atrial septal defect, a ventricular septal defect, ...Read more

How can there be a systolic murmur in mitral stenosis without regurgitation in the mitral area?

How can there be a systolic murmur in mitral stenosis without regurgitation in the mitral area?

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 more

Can you explain why we can hear better the diastolic murmur of mitral stenosis during expiration?

Can you explain why we can hear better the diastolic murmur of mitral stenosis during expiration?

Venous Return: In general when you expire (breath out) you decrease the amount of venous return to the right side of the heart but increases blood volume going to the left heart. Left sided murmurs will increase in intensity with expiration and right sided murmurs will increase in intensity/sound with inspiration. ...Read more

How are aortic stenosis and mitral regurgitation murmur different?

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 more

What are the differences between aortic stenosis and mitral regurgitation murmur?

What are the differences between aortic stenosis and mitral regurgitation murmur?

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

What is mild mitral stenosis?

What is mild mitral stenosis?

Narrowing: Mitral stenosis is a thickening of the mitral valve leaflets. This results in narrowing that restricts blood flow through the valve. Ms is rated as mild, moderate, or severe. Severe ms usually requires valve surgery. Mild does not cause symptoms but should be monitored periodically. ...Read more

What occurs during mitral stenosis?

Restricts blood flow: Mitral stenosis is when the mitral valve fails to open sufficiently. This restricts the blood flow into the left ventricle (the main pumping chamber). This causes the left atrium to dilate and increase pressure in the lungs. This causes shortness of breath, increase BP in lungs, abnormal heart rhythms, and heart failure. ...Read more

Can someone?Die from mitral stenosis?

Yes: Mitral stenosis usually presents with a long history (years)of symptoms including shortness of breath, weakness, arrhythmias and heart failure etc. one can die from this condition. ...Read more

Can someone die from mitral stenosis?

Mitral stenosis: Much more common in under developed countries than in theusa because of inacessible antibiotics on a regular basis to treat rheumatic fever, which is the most common cause of later mitral stenosis which can be lethal if not treated. ...Read more

What are the tests for mitral stenosis?

What are the tests for mitral stenosis?

Echo, cath: Echocardiogram is the most common test for mitral stenosis, as the structure and function of the valve can be assessed visually. Cxr can give information regarding chamber size and valve calcification. Ekg and holter monitor can reveal atrial fibrilation, a common arrhythmia associated with mitral stenosis. Heart cath would reveal the hemodynamics and the need for surgical intervention. ...Read more

Is there a cure for mitral stenosis?

Not exactly: There are several treatment options but no medicine can open the valve. These treatments can reduce the blockage but the falve is still abnormal or replaced with an artificial valve. Sometime a ballon can be inserted thru the valve to stretch it open and improve flow. Rarely can the valve be repaired (unlike a leaking valve which is usually repaired). It can be replaced with an artificial valve. ...Read more

How are tight mitral stenosis & severe mitral stenosis different?

How are tight mitral stenosis & severe mitral stenosis different?

Unsure: "tight" mitral stenosis is not an official medical term. Severe mitral stenosis, as one could imagine is a higher degree of obstruction at the valve with greater consequences on blood flow (cardiac output) and greater consequences on the lungs (buildup of fluid in the lungs.). ...Read more

Can children have mitral stenosis, if so, does this mean it was genetic?

Can children have mitral stenosis, if so, does this mean it was genetic?

Yes: Children may have mitral stenosis. While it is known that there are genes responsible for the direction of cardiac development, mitral stenosis is not specifically linked to a genetic mutation in most cases. ...Read more

Can you tell me the pathophysiology and natural history of mitral stenosis?

Complex: Ultimately mitral stenosis would cause heart failure. The treatment is relief of the stenosis, either by mitral balloon valvuloplasty or mitral valve replacement. This is something that really needs a cardiologist. ...Read more

Why does a patient with mitral stenosis lay on his left side during auscultation?

Why does a patient with mitral stenosis lay on his left side during auscultation?

Better to hear: It positions the tip of the left ventricle closer to the chest wall so that thye stethoscope has a better chance of hearing the low pitched murmur. ...Read more
