Case report shows improved cardiac function after surgical reconstruction of left ventricular aneurysm and pseudoaneurysm, implying enhanced stability in ventricular tachycardia patients.
Background Left ventricular (LV) aneurysm and pseudoaneurysm are rare but potentially life-threatening complications of myocardial infarction. Their coexistence poses significant diagnostic and surgical challenges. Case summary A 69-year-old woman with type II diabetes, hypertension, and dyslipidemia presented with sustained ventricular tachycardia while remaining hemodynamically stable. Multimodality imaging revealed a chronic myocardial infarction with complete right coronary artery occlusion, a large LV aneurysm, and a focal pseudoaneurysm. Urgent LV reconstruction using a Dacron patch was performed. The postoperative course was uneventful, with preserved sinus rhythm and improved ventricular function. Discussion This case underscores the importance of comprehensive imaging to characterize complex post-infarction LV remodeling. Surgical exclusion of scarred myocardium effectively restored LV geometry, improved cardiac function, and reduced arrhythmic risk. The successful repair provides insight into the decision-making process regarding optimal timing and technique for LV reconstruction.
