Treatment of a distal left main trifurcation supported by the TandemHeart left ventricular assist device

Area of Science:

• Cardiovascular Interventions
• Interventional Cardiology
• Medical Device Technology

Background:

• High-risk percutaneous coronary intervention (PCI) poses challenges, especially with impaired left ventricular function.
• Surgical revascularization is not always the primary option for patients with significant comorbidities.
• The TandemHeart left ventricular assist device offers hemodynamic support during complex cardiac procedures.

Observation:

• A patient with poor left ventricular function (Logistic Euroscore 11.4%) underwent high-risk PCI.
• A novel technique was employed to manage a complex left main coronary artery trifurcation.
• This involved dual-catheter intubation, triple kissing balloon angioplasty, and active guiding catheter manipulation.

Findings:

• The TandemHeart device successfully supported hemodynamics throughout the PCI procedure.
• The "aggressive T" stenting technique effectively treated the left main trifurcation.
• Side branch protection with a non-inflated balloon allowed for potential reverse crush stenting if needed.

Implications:

• This case demonstrates a viable strategy for managing complex left main disease in high-risk PCI patients.
• The described novel stenting approach offers an alternative to traditional surgical interventions.
• Successful hemodynamic support with the TandemHeart device is crucial for managing patients with compromised cardiac function during PCI.
