What is diastolic murmur like?

Murmurs... A diastolic murmur just means a sound heard during the diastolic filling phase of the pumping chambers of the heart. For example, mitral stenosis causes a diastolic murmur as blood flows from la to lv during diastole. Aortic regurgitation is a diastolic murmur as blood leaks back through the aortic valve.

What is a diastolic murmur?

Turbulent blood flow. A murmur is a sound that is heard when blood flow is turbulent. Normal blood flow is like a lazy flowing and quiet river. When there is obstruction, the flow becomes turbulent.This is much like when there are rapids in a river and you can hear the sounds. When the sound is heard over the heart, it is called a murmur.When it occurs during diastole, when the ventricles fill with blood it's diastolic. Read more...

Is there diastolic murmur in pulmonal stenosis?

Pulmonary stenosis. The pulmonary valve opens when the right ventricle contracts. This is during systole. So, if there is pulmonary stenosis, the murmur would be observed during systole. If the valve would be leaking, however, that would be heard when the valve is supposed to be closed or during diastole... Read more...

Why can we hear better the diastolic murmur in expiration?

Proximity. In expiration less air is in the lungs moving the heart and great vessels closer to the chest wall and therefore the stethoscope. This makes the murmurs louder and easier to hear. Read more...

How come we got diastolic murmur in pulmonic stenosis?

Irrelevant. Systolic/diastolic irrelevant. Degree of pulmonic stenosis determined on echo and cardiac cath. Depending on severity, corrective intervention warranted. Read more...

A 60y.O. Female complaining of dyspnea and arrythmia with diastolic murmur, what are the possibilities?

Valvular heart disea. In a female particularly if not born in the us a cardiac arrhythmia particularly atrial fib associated with a diastolic murmur suggest mitral stenosis . Non af and diastolic murmur suggest aortic insufficiency which still may be due to rheumatic heart disease . Physical examination is diagnostic and 2d echo is confirmatory. Read more...

Could ventricular septal defect cause diastolic murmur?

Two ways. A large vsd with increased pulmonary blood flow may cause a diastolic flow rumble caused by a large amount of flow coming back from the lungs across the mitral valve into the left ventricle. Perimembranous and supracristal vsds can cause aortic valve deformation, and subsequent development of a diastolic murmur of aortic valve insufficiency. Read more...

Does a? Ventricular septal defect cause a diastolic murmur?

No u. No usually classic murmur is pansystolic (all the way through systole but stops with the second heart sound). Read more...
Holosystolic. Classically, a vsd results in increased blood flow from left to right ventricle due to pressure differences and results in a holosystolic murmur. Several situations where a diastolic murmur may be heard is 1) large vsd results in aortic cusp sucking into vsd and aortic regurg, 2) very large defect with so much flow to lungs and back to left side with diastolic rumble through mitral valve.

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...

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...
