Overview

Large post-MI LV pseudoaneurysms with secondary MR warrant urgent multimodality imaging; this Level 5 case leaves open optimal management.

Key Points

  • Describe the clinical presentation, multimodal diagnostic imaging, and surgical management of a giant left ventricular pseudoaneurysm following myocardial infarction.
  • Evaluated a 62-year-old male presenting with exertional dyspnea 6 months post-myocardial infarction using transthoracic echocardiography, cardiac MRI, and coronary angiography.
  • Performed surgical resection of the pseudoaneurysmal sack, patch plasty repair of the ruptured left ventricular wall, mechanical mitral valve replacement, and coronary revascularization.
  • Imaging revealed a giant 87 × 56 × 84 mm pseudoaneurysm with a 2–3 mm thin wall, late-enhancement scar tissue, mural thrombus, and severe secondary mitral regurgitation.
  • Surgical resection, patch plasty repair, mechanical valve replacement, and right coronary bypass grafting resulted in an uneventful clinical recovery.

Structured PICO

P
Population
A 62-year-old man presenting with a giant left ventricular pseudoaneurysm and severe mitral regurgitation six months after a myocardial infarction.
I
Intervention
Surgical resection of pseudoaneurysm with patch plasty, mechanical mitral valve replacement, and myocardial revascularization of the right coronary artery.
O
Outcome
Clinical recovery

Giant left ventricular pseudoaneurysm is a rare but treatable complication of chronic myocardial infarction, requiring multimodality imaging for diagnosis and surgical intervention.

Cite This Study

Butz et al. (2007) conducted a case report in Giant left ventricular pseudoaneurysm (n=1). Surgical resection, patch plasty, mitral valve replacement, and myocardial revascularization was evaluated on Patient recovery. Surgical resection and repair of a giant left ventricular pseudoaneurysm in a 62-year-old man post-myocardial infarction resulted in an uneventful recovery.
