Pressure Makes us Stronger, Except …

Martin Short joins Steve Martin and Selena Gomez as one of the three stars of the Netflix series “Only Murders in the Building.” His character is that of an aging Broadway Director eager to stage a show who is frequently encountering extraordinary situations, including multiple murders.  In the series’ latest season, he secures financial backing, casts actors and opens a show only to have his principal actor die suddenly and mysteriously (of course) on opening night.   As Director he is confronted with an array of suspicious circumstances and also the understudy is not prepared to assume the leading man’s role. Imagine the difficulties facing the Director; but pressure makes us stronger. He pushes onward by rewriting the play into a musical while continuing to overindulge in a Broadway lifestyle (OK, that sounds appealing). Little does he know that his time is up, he is suffering from pulmonary valve stenosis.  In the show he has a cardiac event, but Meryl Streep comes to his rescue (so it is not all bad). Stenosis of which indicated structure would lead to elevated systolic pressure in the right ventricle?

Stenosis of which valve or structure will result in elevated systolic pressure in the right ventricle?
