Valvular disease Flashcards
severe AS Vmax?
> 4 m/s
severe AS delta P mean?
> 40 mmhg
severe AS AVA?
<1 cmsq
if over 35 with concern for AVR, do what first?
LHC to see if CABG with AVR
indications for AVR with AS?
symptomatic AS, severe AS, asymptomatic but need CABG
who is a good candidate for TAVR?
patient with high surgical risk with severe AS
meds post TAVR?
DAPT 6 months, no AC
aortic stenosis effect on LV?
inc LV O2 demand
murmur of AS?
paradoxical splitting of S2
mitral stenosis physical exam?
low pitch rumbling, opening snap
aortic regurgitation PE?
decrescendo diastolic murmur at left sternal border worse with handgrip, leaning forward or holding breath
who gets surgery with MR?
symptomatic or asymptomatic with EF 30-60%
who needs bridging for AC?
mechanical AVR with clot risk, mechanical MVR, older AVR like ball in cage
tricuspid regurgitation murmur?
systolic murmur that increases with inspiration
what does arrhythmia do to CO in aortic stenosis?
can drop CO because it prevents appropriate diastolic filling
MC post TAVR compliaction?
acute aortic insufficiency
acute aortic insufficiency presentation?
can lead to acute MR, but will have hypotension, tachycardia leading to thready pulses and cold extremities
MC concern post TAVR?
AI
atrial septal defect test of choice?
cardiac cath to determine level of PHTN and size of defect as well as coronary disease
Marfan syndrome is a mutation in what?
fibrillin leads to weakened media in arteries
risk for mitral prolapse
aortic dissection
beta myosin in dilated CM
pseudocoarctation?
thoracic aortic injury with UE HTN and LE hypotension
horse voice with concern for thoracic aortic injury
recurrent laryngeal involvemeent
Mitral valve area mild?
> 1.5 cm sq
severe MS MVA?
< 1cm sq
