Papillary muscle Rupture 

Rupture of a papillary muscle is usually associated with an infarction of which area of myocardium?
  • (A) Inferior
  • (B) Inferior–posterior
  • (C) Lateral
  • (D) Anterior
  • (E) Anteroseptal

The answer is B.
Papillary muscle rupture is usually associated with an inferior–posterior infarction and involves the posterior papillary muscle. Outcome depends on whether the entire muscle body or only the head is ruptured. Rupture of an entire muscle body is associated with a high mortality rate (up to 50 percent within 24 h).

Diagnosis of papillary muscle dysfunction or rupture may be made on echocardiography or by measuring large V waves in the pulmonary artery wedge pressure with a Swan-Ganz catheter.

Papillary Muscle Infarct with Rupture: Gross, an excellent example of ruptured papillary muscle.

How to remember Carpal bones !!

"She Looks Too Pretty; Try To Catch Her":
· Proximal row then distal row, both lateral-to-medial:
  • Scaphoid
  • Lunate
  • Triquetrium
  • Pisiform
  • Trapezium
  • Trapezoid
  • Capate
  • Hamate
· Alternatively: "She Likes To Play; Try To Catch Her".

Note :The scaphoid bone is a small carpal bone on the thumb side (radial side) of the wrist. It is the most commonly fractured carpal bone.

This is probably because it actually crosses two rows of carpal bones, forming a hinge.
