An algorithmic approach to balloon undilatable coronary lesions

Area of Science:

• Cardiovascular Interventions
• Interventional Cardiology
• Vascular Biology

Background:

• Balloon undilatable lesions pose a significant challenge in percutaneous coronary interventions.
• These lesions can be either de novo or occur within previously placed stents.
• Failure to dilate lesions can lead to suboptimal outcomes and procedural complications.

Purpose of the Study:

• To present a systematic, algorithmic approach for treating balloon undilatable coronary lesions.
• To detail various techniques applicable to both de novo and in-stent undilatable lesions.
• To enhance the understanding and application of advanced interventional strategies.

Main Methods:

• The study describes an algorithmic approach to lesion management.
• Techniques discussed include high-pressure balloon inflation, plaque modification balloons, intravascular lithotripsy, and coronary atherectomy.
• Advanced methods like laser coronary angioplasty and extraplaque lesion crossing are also detailed.

Main Results:

• The application of a systematic approach can improve procedural outcomes.
• Knowledge of diverse techniques allows for tailored treatment of undilatable lesions.
• Successful management of these lesions is achievable with appropriate strategies.

Conclusions:

• A structured, algorithmic approach is crucial for managing balloon undilatable lesions.
• Employing a range of advanced techniques increases procedural success and safety.
• This strategy aims to optimize treatment for complex coronary artery disease.
