Question 11

mechanism for mitral valve prolaspse and HCM

decr preload

Answer 11

1) decr preload
2) decr venous return to heart
3) more laxity on chordae so vlave prolapse earlier and louder

Question 12

mechanism for mitral valve prolpase

incr afterload

Answer 12

incr intensity due to incr back pressure on mitral valve

Question 13

mechanism for HCM

incr afterload

Answer 13

greater pressure gradient to overcome

decr obstruction of outflow tract
