Key result
Conservative management of post-MI left ventricular pseudoaneurysm achieves spontaneous thrombosis and 3-year clinical stability.
Why the study?
Left ventricular pseudoaneurysm is a very rare and often fatal complication following acute myocardial infarction with free wall rupture, and long-term prognosis data for conservative treatment are scarce.

Conservative management of post-MI left ventricular pseudoaneurysm may occasionally lead to a benign outcome via spontaneous thrombosis, offering an alternative when surgery is refused.
BACKGROUND: Left ventricular pseudoaneurysm is a very rare complication following acute myocardial infarction, which results from a free wall rupture. Hemopericardium and cardiac tamponade caused by rupture of the free wall after acute myocardial infarction are often fatal. It is difficult to fully document the evolution of left ventricular pseudoaneurysm resulted from acute myocardial infarction with conservative treatment. CASE PRESENTATION: Herein, we followed a 75-year-old female patient for 3 years. Recorded the evolution of the disease: acute lateral myocardial infarction - emergency reperfusion therapy - cardiac rupture - positive successful rescue - the pseudoaneurysm formation - maintaining conservative treatment - gradual enlargement of the pseudoaneurysm - thrombosis in pseudoaneurysm - thrombus filling with pseudoaneurysm - finally stabilized condition - the treatment of coronary revascularization. CONCLUSIONS: This case is reported here because of its scarcity, which provides provides us with a complete record of the entire evolution and an astonishing indication of the long-term prognosis of non-surgical treatment for pseudoventricular.

Li et al. (2020) conducted a case report in Left ventricular pseudoaneurysm following acute myocardial infarction (n=1). Conservative treatment was evaluated on Clinical evolution and long-term prognosis. Conservative treatment of a post-infarction left ventricular pseudoaneurysm resulted in spontaneous cavity thrombosis and clinical stability over 3 years of follow-up.
