What part of the heart valves are "endocardium" and what's the inflow and outflow surface?

I'm a second year and I'm so sick of this. I have read every book and used every online resource. There is a ventricularis or atrialis, and spongiosa, and a fibrosa. I get that and I know their anatomy. For the love of god what part of the valves possess endocardium (does it line them on all sides?) and what is the inflow surface and outflow surface (I thought i.e. for aortic valve it was inflow = on the ventricle side and outflow was aortic side)
Bonus question: what side of the valve do infective endocarditis vegetations form on. I can't find this either. I was assuming inflow because the pictures look like inflow side but I'm not sure.
Notice how I spelled everything out and didn't use abbreviations. Please don't use them lol, I am terrible at knowing what abbreviations stand for. my medical knowledge is good but throw an abbreviation at me and I have no ****ing idea what you're talking about.
Edit: my guess is that endocardium lines the inflow side (if I'm right regarding what inflow side means), i.e. the atrial side of the tricuspid or the ventric side of the aortic valve.

Per B&B bacterial endocarditis is on the atrial side in mitral valve endocarditis, but non-bacterial thrombotic endocarditis is found on both sides of the valve.

The atrial side unless it is Libman-Sachs then it is both sides.

Endocardium is literally the entire inside of the heart.... it’s the cell layer. Endocardium->Myocardium->pericardium (from inside to out).

thanks. I was aware of the layers but sometimes it talks about VALVES having an endocardium, which to me is confusing but ok gotcha lol

The valves are lined by epicardium...

Wow 2nd year sounds turrible, can't wait (notsrs)

I thought third semester was alright, 4th definitely sucks tho.

It sounds like some Anatomy PhD is shoving his phallic toy up your sensitive area. I have done close to over 300 board style quests in Cardio and I honestly don’t know wtf you’re talking about. That means that it’s irrevelant junk.

Thanks all!
