Does the double chimney technique prevent coronary artery obstruction during valve-in-valve TAVI in a patient with high-risk anatomy?
The double chimney technique is a feasible and effective alternative to BASILICA for preventing coronary artery obstruction during high-risk valve-in-valve TAVI procedures.

May offer bailout option in high-risk valve-in-valve TAVI; leaves open need for prospective validation versus BASILICA.
The chimney technique has been utilized to minimize the risk of coronary artery obstruction during valve-in-valve procedures. Here, we present a case involving an 89-year-old female patient with low coronary ostia, severe aortic regurgitation, and intractable heart decompensation caused by degenerated aortic bioprosthesis. The patient underwent a successful transcatheter aortic valve implantation procedure using the chimney technique in both coronary ostia.

Cook et al. (2023) conducted a case report in Degenerated aortic bioprosthesis with high risk of coronary artery obstruction (n=1). Transcatheter aortic valve implantation (TAVI) with double chimney technique was evaluated on Procedural success and coronary patency. In an 89-year-old woman with a degenerated aortic bioprosthesis at high risk for coronary obstruction, a valve-in-valve TAVI using a double chimney technique successfully maintained coronary patency.
