Spontaneous Rupture of Left Ventricular True Aneurysm

Double-chambered left ventricle discovered in patient with ruptured left ventricular aneurysm after myocardial infarction

“…1,[3][4][5] The late rupture of LV true aneurysm is extremely uncommon, because the fibrous scar after myocardial infarction is usually strong and is able to withstand the LV pressure. 6 In the case presented here, however, the patient presented with a concealed rupture of ischemic LV true aneurysm in the setting of double-chambered LV. He had a small separate outpouching in the aneurysm, which had a well-defined boundary.…”

Pseudoaneurysm inside of a true aneurysm

“…Because pseudoaneurysms have a high probability of rupture and death, not only during the early stages of its development but also during the established fibrous stage [5], the patient was quickly sent to surgery with no time to perform MRI. The preoperative diagnosis of the pseudoaneurysm was then essentially based on echocardiography and the definitive diagnosis was only finally established by the surgical report.…”

Mechanical Complications of Myocardial Infarction

“…Atrial and ventricular arrhythmias may occur in the scar tissue, producing palpitations, syncope, and even sudden death. A mural thrombus is often found (50%) [43,44,45,50,51,52,53].…”
