Yup, or, otherwise, you can look at it like it is in First Aid...
On p. 255 on the 2010 FA, we find that a "Holosystolic, high pitched "blowing murmur" is either Mitral or Tricuspid regurg. It's not in the tricuspid area, so this is mitral regurg.
Okay - Since we've established that, in the description, it says "Enhanced by maneuvers that increase TPR (squatting, hand grip) or LA return (expiration)
So, since this is a regurg, then we know that anything which increases the murmur must increase the BACKWARD flow and therefore the opposite is true for increasing the FORWARD flow.
So, anything which decreases TPR or LA return would decrease the backward flow and therefore the murmur. Decreasing LV afterload would decrease TPR. Tadaa...
