Excellent explanations and extremely helpful. Just the right level of simple descriptions and medical terminology.

[jeanjean]

Thank you so much. I wish you also mentioned the effects of this on the pulmonary system

[yasirabozaid]

your electronic hand writing is better than my real hand writing . thanks a lot very helpful

amazing lecture. 4:38 PMI should move laterally and away from the sternum.

[sepidekhorrami]

Thank you so much .if we can say symptoms of AS and AR are as same ?

[deepankurdasila]

You said "the PMI moves medially towards the sternum in LVH whereas in volume overload or left ventricular dilatation it moves laterally or downwards."

I believe in both the conditions the displacement of PMI is laterally or downwards.

Could you please explain or give the reference for this statement.

amazing lecture! simple, precise and easy to understand! thanks for the lecture :)

Awesome video - I know that aortic stenosis occurs in older patient due to naturally aging process non-congenital but what about aortic sclerosis ? I wonder could aortic sclerosis be affiliated with congenital valvular disorder . I thought all a long that the existence of a bicuspid valve was due to just the human evolution because the the tricuspid valve (semilunar valves) need to be cut three slits due to that these valve indicate a much larger blood supply needed to be transport throughout the whole body rather than the lungs .

[cdschlotzhauer]

Wouldn't PMI shift laterally with Left Ventricle Hypertrophy instead of towards the sternum?

[schioncalzanzi]

Age-related calcification is the same as idiopathic degeneration ?

time saver....!! thAnk u so much sir...!!

[eloisaalbertose]

Good day sir, i had my 2d echo 1 year ago and the result was mild aortic regurgitation.. Is this an emergency issue, do i need an operation? Thank u so much if u can explain it to me..

[nazellina]

Why did you say, that when left ventricle is hypertrophied PMI moves medially closer to sternum if it's the oposite - the apex moves laterally and down?

[yuusufmohamedomar]

thank you, you are best lecturer i hope to be like u

[shivaniphalle]

when does it happens on systole or diastolic?

[rimii]

Khan sir can you Linked me the first video that shows how aortic sténosis. I hope you can reply

[BonBonTatinesha]

why do you hear systolic ejection murmur if there is aortic valve dysfunction? If the aortic valve closure is heard on S2, I would've thought the murmur would be heard after... meaning diastolic murmur.

[mohamedmashkor]

detailed echo and doppler echo in A. R. !!??

[seanshannon]

Um is t it pronounced “angIna”? As it vagina ? Bit weird …. Saying angina as what he’s saying it as”
