regurg you want the HR to be
fast
stenosis you want the HR to be
slow
which lesions respond to changes in loading conditions
regurg
most common cause of AS
bicuspid aortic valve
which condition produces a hypertrophied LV muscle mass
AS
how to manage aortic stenosis
slow, full, and tight
most important goal in AS
normal HR. [increase preload, avoid hypotension]
causes of AR
rheumatic heart disease, endocarditis, dexfenfluramine
how to manage regurg
full, fast , forward
what factors contribute to reduced coronary perfusion pressure in patients with aortic regurg
lower diastolic pressure and increased LVEDP
how to manage HR and BP in severe AR
normal to fast HR, avoid incrase in BP, avoid increase in SVR
most common cause of MS
rheumatic
pathophys of MS
overloaded LA, underloaded LV. atrial remodeling and increased PVR
goal for mitral stenosis
slow, full , constricted
