TABLE 4.

Favorable and unfavorable anatomical features of patients.

Anatomy	Favorable for BASILICA	Unfavorable for BASILICA
Calcium	• Typical calcium pattern which spares the nadir of the leaflet	• Confluent calcium at the leaflet nadir  • Bulky calcium mass on the leaflet
Bioprosthesis	• Commissures aligned with native commissures	• Bioprosthetic valve post in-front of coronary artery ostium
Access	• Femoral access for BASILICA catheters preferred for ergonomics	• Non-femoral access (femoral artery or transcaval) for double leaflet BASILICA
Coronary obstruction risk	• Single leaflet BASILICA  • Risk from sinus sequestration	• Double BASILICA not recommended for new operators in their first 2-3 cases
