| Popis: | Introduction We herein present an unusual case of a pseudoaneurysm of the left ventricular myocardium, which is a rare and fatal complication of myocardial infarction. Case report A 64-year-old man with a history of bipolar disorder and arterial hypertension was hospitalized for delayed presentation ST-elevation myocardial infarction. He was admitted to our hospital 24 hours after symptom onset. Diagnostic coronary angiography revealed 95% stenosis at the distal third of the right coronary artery, and he underwent a primary percutaneous coronary intervention to the culprit lesion. Despite administration of a diuretic and optimization of other pharmaceutical treatment, his heart failure deteriorated. Electrocardiography showed a sinus rhythm with Q-wave formation in the inferior wall leads (II, III, aVF), T-wave inversion in the same leads, and borderline QT prolongation (QTc of 490 ms). No ST elevation suggestive of left ventricular aneurysm formation was noticed. Forty days later, cardiac ultrasound revealed a dyskinetic cavity (pseudoaneurysm) in continuity with the posterior–inferior wall of the myocardium, resulting in severe mitral valve regurgitation. Unfortunately, the patient died while awaiting surgical treatment. Conclusion Although most patients with left ventricular pseudoaneurysm have a relatively benign outcome, those with symptoms of heart failure must be urgently diagnosed and treated. |
