SAM and HCM

9 month old male neutered Bengal with a heart murmur. 

Can you have SAM without HCM? Although I do think this case has mild hypertrophy.

Is SAM/DLVOTO only of relevance if causing increased velocity across LVOT with dagger shaped aortic profile?

Is SAM/DLVOTO only of relevance if causing increased velocity across LVOT with dagger shaped aortic profile?

Can you have HCM without diastolic dysfunction (normal mitral inflow pattern)?

Is the only way to differentiate normal from pseudonormal E/A waves the height/velocity with pseudonormal being outside the reference range?

Sorry for all the questions!

Hi!
Yes you can have SAM

Hi!

Yes you can have SAM without signs of HCM. It can be either due to mitral dysplasia or – particularly if there’s no concentric hypertrophy – occur only occasionally (stress).

DLVOTO does ALWAYS cause a dagger shaped profile. But you can miss it when you use PW Doppler

The most practical differentiation between normal and pseudo-normal profiles is that pseudo-normal inflow profiles are associated with left atrial enlargement in 99% of cases

Yes, you can sometimes have HCM without diastolic function when it is just mild (breeding examinations) but usually you will detect some myocardial dysfunction (either diastolic dysfunction as detected by mitral inflow or reduced early diastolic myocardial velocities as detected by tissue Doppler).

… and: DLVOTO sometimes appears and disappears again. This means you can see DLVOTO/SAM on the right side and when you flip the cat over and continue scanning it disappears… That’s cats – always a challenge

Would you say this case has HCM and SAM without evidence of diastolic dysfunction (normal mitral inflow pattern)?
