title: Intraventricular free wall dissection causing acute interventricular communication with intact septum in myocardial infarction.
abstract: This report delineates a previously unrecognized complication of acute myocardial infarction, an intraventricular wall dissection producing interventricular communication without septal perforation. The clinical, hemodynamic, and pathologic features of this unique condition are documented, as well as the factors important in the mechanism of its production.
