Key result
Snare loop fixation successfully managed the dislocation of an endoluminal aortic bifurcation stent graft during TAVR, allowing for valve implantation and subsequent retrieval of the material.
Why the study?
Dislocation of an endoluminal aortic bifurcation stent graft during TAVR is an extremely rare complication with limited reported management strategies.
Case Report (n=1)
Dislocation of a prior aortic stent graft during TAVR is a rare complication that can be successfully managed using a snare loop technique to allow completion of the valve replacement.
Snare rescue may allow TAVR completion after rare stent-graft dislocation; leaves open reproducibility beyond this single case.
Transfemoral aortic valve replacement (TAVR) is an effective way to treat severe aortic valve stenosis, especially in patients who are high-risk for surgery. Dislocation of an endoluminal aortic bifurcation stent graft during TAVR is an extremely rare complication. We present a case on how management of this complication was successfully done. An 86-year-old man presented at the ER after syncope. He was admitted to the cardiology department for further examinations. Transthoracic echocardiography (TTE) revealed severe aortic stenosis. Other comorbidities included endovascular stent graft repair due to an infrarenal abdominal penetrating aortic ulcer. During the following TAVR procedure dislocation of the endoluminal stent graft was observed. Using a snare loop this foreign material was fixated in the right common iliac artery. The patient was hemodynamically stable and endoluminal aortic valve replacement could successfully commence. After implantation of aortic valve bioprothesis, the foreign material was retrieved from the right femoral artery. The patient remained asymptomatic and stable postprocedural. Dislocation of an endoluminal stent graft during TAVR remains a rare complication. This complication can arise due to several factors, including patient-specific anatomical challenges and procedural complexities. Decisions are based on the individual patient but are also made in consensus with the interventional cardiologist' team.

Meledeth et al. (2024) conducted a case report in Severe aortic valve stenosis (n=1). Snare loop fixation and retrieval was evaluated. Snare loop fixation successfully managed the dislocation of an endoluminal aortic bifurcation stent graft during TAVR, allowing for valve implantation and subsequent retrieval of the material.
