Pre‐emptive positioning of a coronary stent in the left anterior descending artery for left main protection: A prerequisite for transcatheter aortic valve‐in‐valve implantation for failing stentless bioprostheses?
Key result
Pre-emptive LAD stenting facilitates safe treatment of LM occlusion during aortic valve-in-valve implantation.

Why the study?
Does pre-emptive positioning of a coronary stent in the left anterior descending artery facilitate safe bailout stenting for left main occlusion during transcatheter aortic valve-in-valve implantation in high-risk patients?
Population
A high-risk patient with a degenerative surgical bioprosthetic aortic valve considered to be at an increased…

Implication
May support bailout strategies in high-risk valve-in-valve TAVI; leaves open prospective validation before wider adoption.

Structured PICO
Does pre-emptive positioning of a coronary stent in the left anterior descending artery facilitate safe bailout stenting for left main occlusion during transcatheter aortic valve-in-valve implantation in high-risk patients?
P
Population
One patient at increased risk of left main occlusion undergoing transcatheter aortic valve-in-valve implantation for a failing stentless bioprosthesis.
I
Intervention
Pre-emptive left main (LM) protection by positioning a coronary stent in the proximal left anterior descending artery prior to transcatheter aortic valve-in-valve (VIV) implantation.
O
Outcome
Procedural safety and effective treatment of left main occlusion.safety
Pre-emptive positioning of a coronary stent in the LAD can facilitate safe bailout stenting in patients at high risk of left main occlusion during transcatheter aortic valve-in-valve implantation.
Cite This Study
Chakravarty et al. (2013) conducted a case report in Failing stentless bioprostheses requiring transcatheter aortic valve-in-valve implantation (n=1). Pre-emptive positioning of a coronary stent in the proximal left anterior descending artery was evaluated. Pre-emptive positioning of a coronary stent in the proximal left anterior descending artery facilitated safe treatment of left main occlusion during transcatheter aortic valve-in-valve implantation.
