HCM Flashcards
genes involved in HCM
B-myosin heavy change, troponin
Echo family screening for HCM
adolescence- q12-18 mo’s and before starting any competitive sport Adult- q5yrs
cut off of LV thickness to call it HCM?
>30mm
when you have pt with CHF sxs and normal EF, what should you think of on boards?
Restrictive CM
Diagnosis?
restrictive CM
what happens to e’ when there is restrictive CM?
decreases
what E, A, and DT characterise a Restrictive FIlling Pattern?
High E, Low A, Short DT
What does Pulmonary Vein flow look like in Restrictive Diastolic Pattern?
Diastolic> Systolic, and Large A wave (same for Hepatic Vein)
name the filling pattern: High E, small A, High E/A, High E/e’, Short DT, Decreased systolic flow in PV and HV
Restrictive
which restrictive CM’s have Dilated Chambers (3)?
Sarcoid, Wegner’s, Hemochromatosis
Diagnosis?
Amyloidosis
Diagnosis? next step?
Hypereosinopilic Syndrome (inflammation–> thrombosis–> fibrosis), check CBC w/ dif.
before diagnosing HCM, which is genetic, what 4 conditions should you rule out?
HTN, AS, Subvalvular mem, infiltrative dz
which LV morphology in HCM is most likely associated with a positive genetif test?
Reverse Curve (banana) septum
LVH > ? mm suggests HCM? > ? mm associated with SCD?
15mm, 30mm
Diagnosis
SAM
when you see an eccentric, posteriorly directed MR jet, WHAT SHOULD YOU THINK OF?
SAM
Diagnosis?
LVOT obstruction causing Premature closing of AV with fluttering from turbulence
diagnose each doppler signal
