Abstract
This report describes a 68-year-old female who, immediately after the primary percutaneous coronary intervention of the left anterior descending artery for acute anterior myocardial infarction, developed an apical aneurysm and a “neo-chamber” within the left ventricular cavity separated from the main cavity by a linear thick hyperechoic free-floating fenestrated membrane. This was an excoriated but perforated subendocardial spiral myocardial layer separated from the subepicardial layer due to ischemia and infarction. Multiple orifices on the inner surface were observed, possibly due to patchy necrosis. In addition, there was a large remote intramyocardial hematoma in the inferolateral wall of indeterminate pathogenesis.
