Use of coils during percutaneous coronary interventions (PCI) is sometimes life-saving and useful althought currently off-label and with unknown clinical outcomes. The study aims to report and compare in-hospital and long-term outcomes of patients undergoing coils implantation for treating coronary perforation or closing coronary aneurysms/fistulas.

Background. Use of coils during percutaneous coronary interventions (PCI) is sometimes life-saving and useful althought currently off-label and with unknown clinical outcomes Objectives. To report and compare in-hospital and long-term outcomes of patients undergoing coils implantation for treating coronary perforation or closing coronary aneurysms/fistulas.

Methods. Among 245.652 PCIs performed in 17 high-volume European centers, patients treated with coils will be identified.

The primary outcome was technical success, defined as the successful sealing coronary perforation or aneurysm/fistulas and procedural success defined as technical success without in-hospital Major Cardiovascular Events (MACe). Long-term MACE and mortality were also reported

Inclusion Criteria:

• Patients with coronary artery perforation or coronary artery fistula/aneurysm suitable treating with coils embolization

Exclusion Criteria:

• Patients without coronary artery disease suitable of coils treatment

Patients with coronary artery perforation or coronary fistula/aneurysm treated with coils embolization during percutaneous coronary intervention
