Coronary artery perforation by intracoronary guide wires: risk factors and clinical outcomes

Area of Science:

• Cardiology
• Interventional Cardiology
• Medical Device Safety

Background:

• Coronary artery perforation is a rare but serious complication during percutaneous coronary intervention (PCI).
• Understanding the incidence and risk factors for guide wire-induced perforation is crucial for improving patient safety.
• Previous studies have highlighted various potential contributing factors, necessitating further investigation into specific procedural elements.

Purpose of the Study:

• To determine the incidence of coronary artery perforation caused by intracoronary guide wires during angioplasty.
• To identify factors associated with guide wire perforation.
• To assess the clinical outcomes and management of coronary artery perforation.

Main Methods:

• Retrospective analysis of 4,353 consecutive angioplasty procedures, treating 6,994 lesions over 8 years.
• Statistical analysis to identify factors associated with perforation, including wire type and lesion characteristics.
• Review of patient outcomes, focusing on complications like cardiac tamponade and management strategies.

Main Results:

• Coronary artery perforation occurred in 15 cases (0.35%).
• Increased use of hydrophilic wires (OR=2.33) and treatment of chronic occlusions (OR=3.31) were associated with perforation.
• Cardiac tamponade occurred in 7 cases (46.7%), with subacute presentation in 6; management included pericardiocentesis and surgical drainage. Tamponade was linked to guide wire number (P=.039) and abciximab use (P=.016).

Conclusions:

• Guide wire-induced coronary artery perforation is an infrequent complication of angioplasty.
• The number of hydrophilic wires used and the complexity of chronic occlusions are significant risk factors.
• While cardiac tamponade is a notable complication, prompt management can lead to favorable outcomes without mortality.
