Coronary perforation with tamponade successfully managed by retrograde and antegrade coil embolization

Area of Science:

• Interventional Cardiology
• Cardiovascular Medicine
• Vascular Surgery

Background:

• The retrograde approach for chronic total occlusions (CTO) has advanced, improving revascularization success rates.
• Epicardial collaterals, often used in retrograde CTO interventions, present unique challenges due to tortuosity and fragility compared to septal channels.
• Coronary perforation is a serious complication of coronary angioplasty, potentially necessitating emergency surgery.

Purpose of the Study:

• To report a rare case of complex coronary perforation during retrograde CTO revascularization.
• To describe the successful management of both retrograde and antegrade coronary perforation with cardiac tamponade.
• To illustrate the utility of coil embolization in managing such critical complications.

Main Methods:

• Performed retrograde chronic total occlusion revascularization utilizing epicardial collateral channels.
• Managed simultaneous retrograde and antegrade coronary perforation.
• Successfully treated cardiac tamponade and vessel rupture using endovascular coil embolization.

Main Results:

• Achieved successful revascularization despite complex collateral anatomy.
• Successfully controlled life-threatening coronary perforation and tamponade via coil embolization.
• Avoided emergency cardiac surgery through percutaneous intervention.

Conclusions:

• Retrograde CTO revascularization via epicardial collaterals, while challenging, can be successful.
• Coronary perforation and tamponade are significant risks but can be effectively managed with coil embolization.
• Coil embolization provides a minimally invasive solution for complex coronary perforations during CTO interventions.
