Predisposing Factors, Demographics, Angiographic Features, and the Possible Role of Inflammation in Coronary...

Area of Science:

• Cardiology
• Interventional Cardiology
• Vascular Medicine

Background:

• Coronary perforation during percutaneous coronary intervention (PCI) is a rare but serious complication.
• Predisposing factors, optimal management, and outcomes for coronary perforation are not well-defined.
• Understanding these aspects is crucial for improving patient care and procedural safety.

Purpose of the Study:

• To identify predisposing factors for coronary perforation during PCI.
• To evaluate optimal management strategies and preventive measures.
• To assess the outcomes of patients experiencing coronary perforation.

Main Methods:

• Retrospective analysis of coronary perforations over a 10-year period at a single catheterization laboratory.
• Review of patient charts, procedural reports, and cineangiograms by independent, blinded operators.
• Statistical analysis of collected data to identify significant associations.

Main Results:

• Nine patients were managed conservatively, six with prolonged balloon inflation, and six with polytetrafluoroethylene (PTFE)-covered stents; one required emergency coronary artery bypass graft.
• No deaths were reported, indicating successful management strategies.
• Patients with perforations showed significantly higher white blood cell counts, absolute neutrophil counts, and neutrophil:lymphocyte ratios, suggesting systemic inflammation.

Conclusions:

• Coronary perforations, though rare, can be life-threatening, with potential risk factors including hypertension, small vessel diameter, high balloon:artery ratio, hydrophilic wires, and myocardial bridging.
• Conservative management or prolonged balloon inflation is effective for most perforations.
• PTFE-covered stents are a potentially life-saving option for large perforations, and elevated white cell counts indicate associated systemic inflammation.
