10. Left Ventricular Aneurysm with Thrombus - Gross
The aneurysm is a large, oval zone located toward the apex of the
left ventricle. An aneurysm forms when a region of the left
ventricular wall is weakened by infarction and then thinned by the
constant pressure of systolic contractions. Aneurysms at any site are
often areas of abnormal flow and thus are predisposed to thrombosis.
The aneurysm in this case has been filled by an organizing thrombus.
Left ventricular thrombi can generate systemic emboli. Ventricular
wall aneurysms may also cause congestive heart failure and dangerous
arrhythmias.
