Post myocardial infarction left ventricular intramyocardial dissecting hematoma penetrated right ventricular outflow tract: a rare complication report.

ABSTRACT:

Background

Intramyocardial dissecting hematoma (IDH) is a rare mechanical complication following myocardial infarction (MI), and only a few isolated cases have been reported to date. IDH presents with diverse clinical manifestations, often resulting in missed or misdiagnosed cases due to limited physician understanding. The diagnosis and treatment of IDH is a major challenge.

Case presentations

We report a case of acute extensive anterior MI in a 73-year-old woman, who underwent percutaneous coronary intervention (PCI); the left ventricular intramyocardial dissecting hematoma (LVIDH) penetrated the right ventricular outflow tract (RVOT), resulting in thrombus formation and subsequent RVOT obstruction. Clinically insignificant IDH was detected by transthoracic echocardiograph
