Left Main Coronary Artery Stent Misadventure

Area of Science:

• Cardiovascular Medicine
• Interventional Cardiology
• Cardiac Surgery

Background:

• Coronary artery bypass grafting (CABG) is the traditional treatment for left main coronary artery (LMCA) disease.
• Percutaneous coronary intervention (PCI) is an emerging alternative for LMCA disease, offering a less invasive approach.
• LMCA PCI can present significant technical challenges and risks of procedural failure.

Purpose of the Study:

• To highlight the potential difficulties and complications associated with LMCA PCI.
• To present case studies of LMCA PCI failure.
• To underscore the importance of surgical intervention as a fallback in complex LMCA interventions.

Main Methods:

• Retrospective review of two complex cases involving LMCA PCI.
• Detailed description of the PCI procedures attempted.
• Documentation of reasons for PCI failure and subsequent surgical management.

Main Results:

• Both cases experienced technical failure during LMCA PCI.
• The failures necessitated conversion to emergency coronary artery bypass grafting (CABG).
• Surgical outcomes for the patients were not detailed but implied successful salvage.

Conclusions:

• LMCA PCI, while a viable option, carries a risk of failure that requires careful consideration.
• The potential need for emergent surgical intervention must be anticipated in LMCA PCI.
• Experienced surgical backup is crucial when performing complex LMCA interventions.
