He is a 18 year old male that was admitted for shortness of breath. Your attending ask you to examine the patient and look for a murmur compatible with:
a. mitral stenosis b. pulmonic stenosis c. aortic stenosis d. aortic insufficiency e. bicuspid aortic valve

You are right!
1. what is the mechanism? 2. wich valve abnormality is more common in marfan than ao.insuficiency?

Connective tissue is week in the vessel walls so high pressure distends the root of aorta >>> aortal insufficiency. the other anomaly could be weakness of mitral valve leaflets - there will be prolapse

perfect!
Lets said that this patient has a MITRL VALVE PROLAPSE What ahppen with his murmur during valsalva and during squating?

MVP during valsalva-->reduce preload-->increase murmur
squatting increase preload,increase afterload---->decrease murmur |
