Abstract
Introduction
Left ventricular pseudoaneurysm (LVP) is a rare complication of myocardial infarction associated with very high mortality. Patients with LVP may present with heart failure, ventricular arrhythmias, or even cardiac tamponade. If left untreated, the risk of rupture may reach up to 45% within the first year.
Case presentation
We present the case of a 76-year-old patient with a recent myocardial infarction, diabetes, renal failure, stroke, and tetraparesis, admitted to the Neurology Department of the Clinical Rehabilitation Hospital in Cluj-Napoca. A cardiology consultation was requested for sudden-onset dyspnea, palpitations, and deterioration of the general condition. Clinical examination showed SpO2 79% and HR 100/min, without cardiac murmurs. Echocardiography revealed mildly reduced LVEF, a giant posterior LVP, dilated right heart chambers with signs of right ventricular overload, and bilateral pleural effusion. CT angiography excluded pulmonary embolism and confirmed the presence of LVP. The symptoms were interpreted as acute heart failure. Surgical closure was considered, but the Heart Team decided on conservative management due to the extremely high perioperative risk. During hospitalization, the patient developed multiple complications and eventually died following pseudoaneurysm rupture and cardiac arrest.
Conclusion
Left ventricular pseudoaneurysm is a rare but life-threatening complication of myocardial infarction that requires early diagnosis and prompt management. This case highlights the challenges of treating patients with multiple comorbidities and very high surgical risk, in whom the lack of definitive treatment options may lead to a fatal outcome.
