Bioprosthetic or native aortic scallop intentional laceration to prevent iatrogenic coronary artery obstruction (BASILICA) prevents coronary obstruction during transcatheter aortic valve replacement (TAVR). This review offers guidance on BASILICA techniques to improve operator proficiency.
Area of Science:
- Cardiology
- Interventional Cardiology
- Medical Devices
Background:
- Coronary artery obstruction is a serious complication of transcatheter aortic valve replacement (TAVR).
- Preprocedural computed tomography can identify obstruction risk.
- Bioprosthetic or native aortic scallop intentional laceration to prevent iatrogenic coronary artery obstruction (BASILICA) is an effective preventative technique.
Purpose of the Study:
- To provide contemporary best-practice guidance for BASILICA and related leaflet modification strategies.
- To synthesize international experience and address barriers to BASILICA adoption.
- To enhance operator proficiency in preventing TAVR-induced coronary obstruction.
Main Methods:
- State-of-the-art review of international experience with BASILICA.
- Detailed explanation of transcatheter electrosurgery principles.
- Guidance on risk assessment using computed tomography and procedural planning.
- Step-by-step procedural guide for electrosurgical BASILICA.
- Discussion of uncommon challenges, limitations, and variant techniques.
Main Results:
- BASILICA effectively prevents TAVR-induced coronary obstruction.
- Technical complexity and limited training have hindered BASILICA adoption.
- The review provides comprehensive guidance on risk analysis, planning, and execution of BASILICA.
- Variant techniques and strategies for challenging scenarios are presented.
Conclusions:
- Contemporary best practices for BASILICA can improve operator proficiency.
- Addressing technical complexity and training needs is crucial for wider adoption.
- BASILICA and related techniques offer a vital solution for preventing coronary obstruction during TAVR.

Heart Valves
The AV valves prevent the backflow of blood from the ventricles to the atria during ventricular contraction. These valves function with the assistance of the chordae tendineae and papillary muscles. When the ventricles are relaxed, the chordae tendineae are slack, allowing blood to flow from the atria into the...
