Welcome back! You have a first year medical student tagging along and send her to listen to a murmur. She describes a mid to late diastolic rumble heard at the apex. S1 sounds normal and there is no opening snap. You are an old school pharmacologist so you administer inhaled amyl nitrate. The murmur decreases in intensity and duration. As you teach the medical student, you pull out an old pathology slide:
Challenge: What's the murmur? What's the valve defect? What does the slide show?
