Use of Snare Catheter Technique in Transcatheter Aortic Valve Replacement With Self-Expandable Valve: Expert Review

The use of the snare catheter (SC) technique has been described in the field of interventional cardiology, in particular in the retrieval of a lost device, for example, a dislodged coronary stent, broken coronary wire, and so forth. In the transcatheter aortic valve replacement (TAVR) procedure, some cases have been observed where the anatomy is challenging or there are scenarios where some complications occur during the procedure, which make it necessary to use some tools to achieve the success of the procedure. The SC has shown are very useful either to achieve the ascent of the valve to the annular plane in complex anatomies or as a rescue measure in the event of complications that may arise after valve implantation.
