title: Survival in Infarct Related Intramyocardial Dissection Importance of Early Echocardiography and Prompt Surgery.
abstract: Infarct related intramyocardial dissection, an unusual mechanical complication associated with recent inferior/inferoposterior myocardial infarction, is characterized by a septal defect and a dissection tract that originates on the left side of the interventricular septum, extends beyond the septum into the right ventricular free wall, and subsequently re-enters the right ventricle. The utility of echocardiography for diagnosis has been described. Despite aggressive therapy, the prognosis of intramyocardial dissection is reported to be dismal. We describe the use of prompt echocardiography in two patients, which established the diagnosis of infarct related intramyocardial dissection allowing early definitive surgery and long-term survival.
