A large left ventricular pseudo–aneurysm detected 5years after acute myocardial infarction

Dr. Rajendra Dhar, Dr. Meenakshi Rana

Abstract :

Left Ventricular pseudo–aneurysms are false aneurysms that result from contained myocardial rupture, a rare complication of myocardial infarction, occurring most often 3–7 days post–MI¹. The cardiac rupture is contained by adherent pericardium or scar tissue. In contrast, Left Ventricular aneurysm has a wall of scarred myocardium. A pseudo–aneurysm typically has a narrow neck, the each in LV wall being less than 50% of its maximal diameter, while true aneurysm has a wider base. Pseudo–aneurysms have to & fro blood flow into the cavity, contained by pericardium, thrombus or adhesions. The natural history of surgically treated and untreated left ventricular pseudo–aneurysms is not clearly defined and is based on retrospective single centre case series^7,8. Diagnosis is confirmed by Cardiac Angiography, 2D Echocardiography, Cardiac CT or MRI.

We hereby present a case of a large left ventricular pseudo–aneurysm presenting with intermittent high grade fever, palpitations and chest discomfort, five years after inferior myocardial infarction which was managed with PCI/PTCA with stent in proximal left circumflex on admission.
