Does a ?Ventricular septal defect cause a diastolic murmur?

Does a ?Ventricular septal defect cause a diastolic murmur?

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. ...Read more

Heart Murmur (Definition)

Heart murmurs are clinical findings in which a physician hears a murmur (a sound caused by the flowing and turbulence of blood) during the physical exam of a patient. Murmurs occur due abnormalities in the valves of the heart ...Read more

Could ventricular septal defect cause diastolic murmur?

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

Hello doctors, can ventricular septal defect cause diastolic murmur?

Hello doctors, can ventricular septal defect cause diastolic murmur?

Not typical: The classic VSD physical finding is of course a holosystolic murmur. However, if the VSD is subarterial or supracristal, it can distort the aortic valve, sometimes causing leaflet prolapse. If this results in significant aortic insufficiency, there will be an associated diastolic murmur (with the insufficiency representing an indication for surgical repair). ...Read more

Can ventricular septal defect cause diastolic or systolic murmur?

Can ventricular septal defect cause diastolic or systolic murmur?

Yes: Almost all vsd's cause a syhstolic murmur. Larger defects with a lot of flow across them cause a diastolic murmur from increased flow across the mitral valve. ...Read more

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

What is diastolic murmur like?

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. ...Read more

Is there diastolic murmur in pulmonal stenosis?

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?

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?

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
