Аннотация
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.
