- Ventricular Aneurysms usually occur in the left ventricle and develop during the healing phase following a myocardial infarction. In most cases ventricular aneurysms are the result of dyskinetic, injured areas of the myocardium which do not produce tension during systole. Consequently, these areas bulge out during myocardial contraction and over time evolve into true aneurysms.
- The primary concern of ventricular aneurysms is their capacity to act as a substrate for mural thrombi and thus potentially produce thromboemboli. Additionally, ventricular aneurysms can derange electrical flow within the heart and thus lead to arrhythmias.
