LATE SYSTOLIC MURMURS

Question 1

what are the late systolic murmurs?

Answer 1

mitral valve prolapse

ischemic mitral regurgitation

Question 2

MVP normally mid-systolic click; no murmur unless MR present
(Most common etiology for mitral valve prolapse is redundancy of valve tissue with respect to
the valve ring [“floppy” valve or Barlow’s syndrome])

Most common cause of a late systolic murmur; best heard with the diaphragm of the stethoscope, over
or just medial to the cardiac apex; usually preceded by single or multiple clicks

MVP with late systolic murmur is associated with mild mitral regurgitation and is not accompanied by an S3 or signs of pulmonary hypertension; LV function is normal

Answer 2

*Mitral valve prolapse

Question 3

Papillary muscle displacement (previously known as papillary muscle dysfunction) in patients with
“ischemic mitral regurgitation” due to acute or chronic myocardial infarction or myocardial ischemia

Answer 3

*Ischemic mitral regurgitation
