Balloon-assisted bioprosthetic or native aortic scallop intentional laceration to prevent iatrogenic coronary artery obstruction with en face view for patients exhibiting severe calcified leaflet: a case report.

ABSTRACT:

Background

Balloon-assisted bioprosthetic or native aortic scallop intentional laceration to prevent iatrogenic coronary artery obstruction (BA-BASILICA) enables valve-in-valve transcatheter aortic valve implantation (ViV-TAVI) in patients at risk of coronary artery obstruction. However, its efficacy in patients with severely calcified leaflets remains unclear.

Case summary

We report a 78-year-old woman with a deteriorated 21 mm Carpentier-Edwards PERIMOUNT Magna valve. Computed tomography showed severe calcification in the left coronary leaflet, extending above the left coronary artery (LCA) ostium, with a virtual transcatheter heart valve to coronary ostium distance of 3.7 mm, indicating a high risk of coronary obstruction after ViV-TAVI. We performed ViV-TAVI using the BA
