Key result
TEVAR stent successfully flattens and stabilizes an embolized TAVR valve to allow new valve implantation.
Why the study?
Transcatheter aortic valve replacement for severe aortic stenosis carries the risk of severe complications, including device embolization.
Case Report (n=1)
A novel management strategy using a TEVAR stent can successfully stabilize an embolized TAVR valve in the aorta, allowing for the implantation of a new valve.
May offer a bailout for rare TAVR embolization; leaves open reproducibility and dedicated-device needs.
Transcatheter aortic valve replacement (TAVR) is a common treatment for severe aortic stenosis (AS), but it carries the risk of severe complications, including device embolization. We present a case of a TAVR valve embolization into the left ventricular outflow tract (LVOT), diagnosed with transesophageal echocardiography (TEE) shortly after device deployment. The dislodged valve was successfully retrieved from the LVOT into the aorta, flattened, and stabilized with a thoracic endovascular aneurysm repair (TEVAR) stent, enabling the successful implantation of a new TAVR valve.

Jouryyeh et al. (2025) conducted a case report in Severe aortic stenosis with TAVR valve embolization (n=1). Retrieval and stabilization of embolized TAVR valve using a TEVAR stent was evaluated on Successful retrieval and stabilization of the embolized valve, enabling implantation of a new TAVR valve. An embolized TAVR valve in the left ventricular outflow tract was successfully retrieved, flattened, and stabilized using a TEVAR stent, allowing for the implantation of a new TAVR valve.
