Patients with mitral valve prolapse may have a mid-systolic click along with a murmur. There are no other valve conditions that would be associated with the ausculation.
It is best heard with diaphragm, at the apex, but also may be heard at the left lower sternal border. The click is usually followed by a systolic murmur. The click and murmur
move with postural changes.
There may have been a postural change or stethoscope placement.
Thanks for your question. Take care.
