Key result
Step-by-step TEE protocol guides the BASILICA procedure based on >50 cases.
Why the study?
No structured echocardiographic imaging protocol had been described to guide the BASILICA procedure during transcatheter aortic valve replacement.
Provides a structured TEE imaging protocol to guide the BASILICA procedure and prevent iatrogenic coronary artery obstruction during TAVR.
May support standardized TEE guidance for BASILICA; leaves open prospective validation before routine adoption.
Bioprosthetic or native aortic scallop intentional laceration to prevent iatrogenic coronary artery obstruction (BASILICA) is a recently developed technique to reduce the risk of ostial coronary obstruction during transcatheter aortic valve replacement. Intraprocedural fluoroscopy and transesophageal echocardiography imaging are used complimentarily to guide the procedure. So far, no structured echocardiographic imaging protocol has been described for this intervention. Based on an experience of more than 50 BASILICA procedures at two different institutions, we present a step-by-step approach for transesophageal echocardiography guidance during BASILICA and highlight anatomical and procedural characteristics from an echocardiographic perspective.

Protsyk et al. (2021) conducted a review in Transcatheter aortic valve replacement at risk of ostial coronary obstruction (n=50). Transesophageal echocardiography guidance during BASILICA was evaluated. A structured step-by-step approach for transesophageal echocardiography guidance during the BASILICA procedure was developed based on experience from over 50 cases at two institutions.
