Coronary Artery Aneurysm After Mini-Crush Drug-Eluting Stent Technique in a Chronic Total Occlusion

Area of Science:

• Cardiology
• Interventional Cardiology
• Vascular Surgery

Background:

• Chronic total occlusions (CTOs) of coronary arteries present complex revascularization challenges.
• Bifurcation lesions add complexity to percutaneous coronary intervention (PCI) strategies.
• Coronary artery aneurysms are rare but serious complications following PCI.

Observation:

• A 53-year-old male patient presented with a chronic total occlusion of the circumflex artery.
• The CTO involved a significant bifurcation, complicating treatment planning.
• Percutaneous coronary intervention was performed using a mini-crush technique with two drug-eluting stents.

Findings:

• The case describes a coronary artery aneurysm developing in the context of a bifurcated CTO.
• Successful revascularization was achieved using a novel two-stent mini-crush approach.
• This represents the first documented instance of a coronary artery aneurysm in a bifurcated CTO treated with this technique.

Implications:

• This case highlights a rare complication and a potential treatment strategy for complex coronary artery disease.
• The mini-crush technique may be effective in managing bifurcated CTOs complicated by aneurysms.
• Further research is warranted to understand the incidence and optimal management of such complex cases.
