  • Title: Bioprosthetic aortic valve leaflet disruption with high energy electrocautery to prevent coronary artery obstruction during valve-in-valve transcatheter aortic valve replacement.
    Author: Nelson BC, Chadderdon S, Song H, Zahr FE.
    Journal: Catheter Cardiovasc Interv; 2019 Jan 01; 93(1):164-168. PubMed ID: 30298684.
    Abstract:
    Transcatheter aortic valve replacement (TAVR) is well-established for the treatment of bioprosthetic aortic valve stenosis (AS) in high surgical risk patients. Coronary artery obstruction from displacement of the bioprosthetic valve leaflets during valve-in-valve (VIV) TAVR is a rare, but potentially fatal, complication. Recently, the bioprosthetic aortic scallop intentional laceration to prevent iatrogenic coronary artery obstruction (BASILICA) procedure was developed as a method for disrupting bioprosthetic leaflets in patients undergoing VIV TAVR at high risk for coronary obstruction. This case describes a successful VIV TAVR utilizing a simplified concept of the BASILICA technique in a patient where the full procedure could not be completed.
