From: Intraventricular muscle bundle as a novel cause of left ventricular aneurysm
Morphological and hemodynamic changes in abnormal ventricular muscle bundle-associated ventricular aneurysm, left ventricular diverticulum and ventricular aneurysm formation after MI. In both abnormal muscle bundle-associated ventricular aneurysm and left ventricular diverticulum, blood flows from the main chamber into the sub-chamber during the systolic phase, and high-speed blood flow can be detected in the communication. The direction of diastolic blood flow is opposite. However, blood flow into and out of the post-MI aneurysm is not obvious. MI, myocardial infarction
