Successful revascularization of a long chronic total occlusion with blunt microdissection complicated by coronary...

Area of Science:

• Cardiology
• Interventional Cardiology
• Vascular Medicine

Background:

• Chronic total occlusions (CTOs) present significant challenges in percutaneous coronary intervention (PCI).
• Coronary artery dissection can complicate CTO recanalization, potentially hindering true lumen access.
• The LuMend Frontrunner catheter is a specialized device for navigating complex coronary lesions.

Observation:

• A case involving percutaneous revascularization of a CTO was complicated by an extensive coronary artery dissection.
• Initial attempts to access the true lumen after dissection were unsuccessful.
• The patient underwent a follow-up assessment at 7 weeks post-procedure.

Findings:

• Favorable healing of the coronary artery dissection was observed at the 7-week follow-up.
• Successful access to the true lumen was achieved following the healing period.
• The LuMend Frontrunner catheter facilitated the successful revascularization of the CTO.

Implications:

• This case demonstrates the feasibility of achieving procedural success in CTOs complicated by dissection with delayed true lumen access.
• The LuMend Frontrunner catheter can be a valuable tool in managing complex coronary dissections during PCI.
• Favorable healing may restore true lumen anatomy, enabling successful intervention in previously inaccessible lesions.
