Equipment entrapment during redo-TAVR with successful BASILICA procedure

Catheter Cardiovasc Interv. 2021 Aug 1;98(2):E320-E323. doi: 10.1002/ccd.29485. Epub 2021 Jan 23.


Transcatheter aortic valve replacement (TAVR) for transcatheter heart valve failure has been suggested for high-risk patients. TAVR-in-TAVR, however, may lead to complex leaflet interactions causing coronary ostial obstruction, which is a devastating complication. Coronary protection with provisional stent placement may be challenging. We describe the first percutaneous transaxillary case of TAVR-in-TAVR with Bioprosthetic Aortic Scallop Intentional Laceration to prevent Iatrogenic Coronary Artery obstruction (BASILICA) where guide catheters used for coronary protection were entrapped between the valve frames. We describe anatomical predictors and management considerations. Operators should be aware of this important complication during TAVR-in-TAVR valve placement.

Keywords: aortic stenosis; bioprosthetic valve failure; transcatheter aortic valve replacement.
