I came across your channel just an hour ago...n I have become a huge fan of yours...awesome collection ...relieved my final professional exams tension!!!

I'm grateful I've come across these fantastic videos! My question is if anybody is able to hear sound 3 here... I'm struggling a bit with this one. Thanks!

why does it say in my book that a wider splitting is due to short ventricular systolic duration

volume is too low bt information is valuable 😊 thank you for sharing

Amazing one! Mitral regurge sound (muffled S1) Splitting S2 S3 Three murmurs by one rock! Which means Two other murmurs associated with MR Splitting S2 S3

Wouldn't the splitting of S2 be lesser since aortic valve closes later due to LV volume overload?

Cardiac output is less. Ejection fraction is less because of the regurgitation. Some of the blood is going back to the left atria, causing a longer splitting of S2.

The S2 is due to the closure of pulmonary valve and aortic valve. This sound splits because the pulmonary valve closes before the aortic valve. So when the aortic valve takes more time to close, that would increase the splitting 🙃

It's the other way around ​@@lochanasenadheera6226

Will all the murmurs be masked if there is associated Atrial fibrillation ?

No. Just presystolic accentuation

Can we exclude aortic stenosis based on auscultation?

No. Severe Aortic Stenosis may give you no murmur

Can anyone explain gallavardin phenomenon?

Gallavardin Phenomenon was described by Louis Gallavardin (French Cardiologist) in patients with Aortic Stenosis. In some patients of Aortic stenosis, its murmur is dissociated into harsh & musical components. Harsh components is heard on right 2nd intercostal space radiating to neck (the usual murmur of aortic stenosis). while musical component is heard on cardiac apex & can be confused as systolic murmur of Mitral regurgitation. Differentiating features: 1. Murmur of Aortic stenosis will not radiate to axilla while MR radiates to axilla. 2.Maneuvers during auscultation are useful. Handgrip increases resistance to arterial forward flow and facilitates regurgitant reverse flow. It therefore, increases the murmur of MR and decreases the intensity of the AS murmur. 3. Slowing of heart rate (such as after compensatory pause of premature beat) will accentuate murmur of Aortic Stenosis while MR murmur will remain unchanged. I hope it helped you !

How to separate from AS murmur? For me it sounds the same

The Gallavardin phenomenon occurs when someone confuses the murmur of aortic stenosis for mitral reegurgitation. This usually occurs when a murmur of aortic stenosis is heard over whole of the precordium. The differentiating feature between both is the site of maximum murmur intensity and radiation of murmur. The murmur of MR shall radiate to the left axilla while that of aortic stenosis will not radiate to this site no matter how loud you are hearing murmur at the apex.

My professor taught us MR murmur sound like "Sha~ To, ko~" but absobloodylutely different lol

Can this sound be heard with mild mitral regurgitation?

Yes. Intensity grade of murmur will be lower. kzread.info/dash/bejne/Y4iG24-GoK-chtI.html

I.cant hear anything

Listen at 2x to simulate real patient

👍👍👍👍🫀
