A Novel Interventional Approach to LV Pseudoaneurysm Compressing on LAD by Utilizing LAA Closure Device

Area of Science:

• Cardiovascular Interventions
• Minimally Invasive Surgery
• Interventional Cardiology

Background:

• Left ventricular pseudoaneurysm poses a significant risk of rupture and mortality.
• Surgical intervention is often contraindicated in high-risk patients.
• Transcatheter techniques offer a potential alternative for complex cardiovascular conditions.

Observation:

• A novel transcatheter approach was utilized for a patient with left ventricular pseudoaneurysm.
• The procedure involved off-label use of a left atrial appendage (LAA) closure device, coiling, and concurrent left anterior descending stenting.
• This was performed in a patient deemed unsuitable for traditional surgery.

Findings:

• Successful application of a transcatheter strategy combining LAA closure device, coiling, and stenting.
• Demonstrated feasibility of a multidisciplinary approach involving interventional cardiology, cardiothoracic, and neurosurgery.
• Managed a complex case of left ventricular pseudoaneurysm in a high-risk, non-surgical candidate.

Implications:

• Highlights the potential of innovative transcatheter techniques for complex structural heart disease.
• Emphasizes the critical role of collaborative care in managing challenging cardiac pathologies.
• Provides a potential treatment pathway for patients with left ventricular pseudoaneurysm who are poor surgical candidates.
