[Percutaneous treatment of coronary chronic total occlusions: state of the art]

Area of Science:

• Cardiology
• Interventional Cardiology

Background:

• Percutaneous coronary intervention (PCI) for chronic total occlusions (CTO) can yield favorable outcomes in specific patient groups.
• Significant advancements in materials and strategies have improved CTO intervention success rates over recent decades.
• CTO interventions continue to present challenges, with higher complication and lower success rates than standard PCI.

Purpose of the Study:

• To present updated evidence on the clinical benefits of recanalizing chronic total occlusions.
• To detail specialized interventional techniques for successful CTO recanalization.

Main Methods:

• Review of current literature and interventional strategies for CTO PCI.
• Analysis of clinical outcomes and complication rates associated with CTO interventions.

Main Results:

• Successful CTO PCI is linked to positive clinical outcomes in carefully selected patients.
• Dedicated interventional cardiologists specializing in CTO can achieve success rates approaching 90% with minimized complications.
• Specialized techniques and materials are crucial for navigating complex CTOs.

Conclusions:

• CTO recanalization is a valuable therapeutic option for selected patients, improving clinical outcomes.
• The development of specialized techniques and the expertise of dedicated CTO operators are essential for optimizing success and safety.
• Further advancements in interventional strategies are expected to enhance the efficacy of CTO PCI.
