Causes Of 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 moreSee 1 more doctor answer
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
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
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
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
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
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
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
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 moreSee 1 more doctor answer
When doctor said he heard an "opening snap", is it a systolic or diastolic murmur? Never heard before. Echo: trivial tricuspid reg, with TVG of 11mmhg
Depends: There are many different types of murmurs, not all are a problem. A good physical may be all that is needed . Other testing such as echocardiograhy can be very helpful. See your doctor. ...Read more
Many things: The most common systolic murmur is an innocent flow murmur. Some murmurs represent rapid blood flow through a tight valve or tube, some rapid flow through a whole. Many docs are rained to know based on exam, but a cardiac ultrasound is sometimes done to confirm or exclude the initial impression. ...Read more
Many are Normal: Many children develop Heart murmurs as they grow. They are caused by blood vibrating the heart as it beats. Sometimes it can be caused by a hole in the heart or other abnormal changes in heart valves. A visit to a pediatric heart specialist would be a great way to clarify this. Most of them are innocent ( not a significant health issue) and resolve without treatment. Get it checked ...Read moreSee 1 more doctor answer
