Myocardial Infarct with Rupture

Myocardial Infarct with Rupture •View of superior surfaces of transverse sections with the anterior surfaces facing towards the left. •Note the hemorrhagic transmural infarct in the postero- lateral wall. The arrow points to a hemorrhagic rupture tract. A subepicardial hematoma forms which ruptures with tamponade averaging 200-250 cc. •A rupture leaking 2 drops/sec yields 360 cc in an hour. •Ruptures are rarely gross holes in the ventricular walls. IV septal cases survive longer, even months, and do form visible defects due to the high pressure of a L-R shunt. (Description By:J. Hasson, M.D. ) (Image Contrib. by: UCHC )
