Key result
Percutaneous snare successfully retrieves a protruding aorto-ostial coronary stent prior to TAVR.
Why the study?
Intentional percutaneous removal of deployed coronary stents is feared due to severe complications and rarely reported, with most patients referred to surgery.
Is percutaneous snare-based retrieval of a protruding coronary stent feasible in a patient referred for TAVR?

Is percutaneous snare-based retrieval of a protruding coronary stent feasible in a patient referred for TAVR?
Percutaneous snare-based retrieval of protruding coronary stents is technically feasible and offers a practical solution when aorto-ostial stent protrusion threatens structural interventions like TAVR.
Snare retrieval of protruding coronary stents may enable TAVR in select cases; single-case experience leaves open need for prospective validation.
BACKGROUND: An 89-year-old woman was referred for transcatheter aortic valve replacement (TAVR). She had a history of ostial right coronary artery stent that was protruding into the aorta with the risk of interaction with the TAVR prosthesis. CASE SUMMARY: Using femoral arterial access, a Goose Neck snare was advanced and captured the overhanging part of the stent. The stent was successfully retrieved, followed by restenting of the ostial right coronary artery with intravascular ultrasound guidance. DISCUSSION: There are only a few case reports of percutaneous removal of deployed stents, whether accidentally or intentionally. Intentional removal of deployed stent is feared given the possibility of severe complications, and most patients who require such intervention are referred to surgery. TAKE-HOME MESSAGES: Percutaneous removal of protruding coronary stents is technically feasible. This case demonstrates that snare-based retrieval is a practical solution when aorto-ostial stent protrusion threatens both coronary and structural interventions.

Nakhle et al. (2026) conducted a case report in Protruding ostial right coronary artery stent (n=1). Percutaneous stentectomy (snare-based retrieval) was evaluated on Successful stent retrieval. Percutaneous snare-based retrieval of a protruding aorto-ostial coronary stent was successfully performed in an 89-year-old woman prior to TAVR.
