You could always use it on that flap in your throat (epiglottis?) that keeps food from going into your lungs. (Suffocation from choking on food is usually caused by the food wedging down that flap so you can't get air into the lungs.)
Of course, if you can target the valve in the heart, even less pressure would be needed to seriously mess up someone.
If you want that kind of possible game breaking abuse allowed, there are ways to moderate it. Do you require them to have a sensory link (visual, touch, etc) with what they are trying to target? If so, they are going to need to use some kind of Clairvoyance to find their target, since this is inside a body. Second, better start making medic rolls since the guts of a living creature are a tricky and messy place to find something in even when using the psychic equivalent of an endoscope... After all, clairvoyance isn't x-ray vision, so no convenient 'visible human' effects here.
I know those limitations won't stop the truly obsessed with 'perfect assassinations', but there is one more way to chill them out on the idea. Let them know that doing or talking about that kind of stuff is stepping on the toes of some real assassins, and they don't give warnings twice, if at all...
I like.
