i didn't catch ur question exactly..but,i'm telling what i know...

x-descent is due to TV downward displacement in systolic phase(when blood ejected into pulm. artery)

y-descent--due to TV opening with blood flow into right ventricle(in diastole)

Tricuspid stenosis is pathology associated with tricuspid valve opening...
so, in TS.......y- descent will be slower than normal.....as valve is stenosed..
i think, there won't be an affect in x-descent..as it occurs in systolic phase.....
changes seen in TS----giant 'a' wave,slow 'y' descent...
correct me if i'm wrong

y wave on jvp corresponds to emptying of rt atrium into the ventricle. In tricuspid stenosis as its hard to get blood out of the tricuspid valve into rt ventricle there is slow y descent. I think you have confused with x and y . I dont know why x descent should be altered in TS Please explain.. X descent would be altered in T regurgitation..

guys i was listening to cardiac physiology kaplan 2010 lectures and he says that x-descent would finish and doesnt even comment on y-descent
but
em also of the same view point that there would be
1. large a -wave
2.slow / small y descent as blood cant easily go to rt ventricle

but

if we think in this that due to tricuspid stenosis----> y-descent is slow--------------> that more than normal volume of blood remains in atria after y-descent---------> after that atria contracts still it cant flush whole of blood --------------->so there is already much blood in atria at the point where there would be normal x-descent so----->slow x-descent


PLEASE TELL IF YOU PEOPLE AGREE BECAUSE THAT CARDIO GUY IS REALLY GOOD MAY BE HE MESSED UP

thanks venkyy and dr. nitowl u helped me alot

i don't know whether it would be slow x-descent...but, i'm sending u a link it might be helpful
but, it's saying a prominent x-descent in tricuspid stenosis though..
