Left Ventricular Guidewire (LV-GW) Pacing
Left Ventricular Guidewire (LV-GW) Pacing is a technique used during Transcatheter Aortic Valve Replacement (TAVR) to provide rapid ventricular pacing without the need for a separate temporary transvenous pacing wire. This approach utilizes the stiff guidewire already positioned within the left ventricle for transcatheter heart valve delivery, allowing the procedural team to electrically stimulate the myocardium and temporarily control the heart rate during critical stages of valve implantation.
The primary goal of left ventricular guidewire pacing is to create a brief period of controlled hemodynamic stability during valve deployment, allowing for precise positioning and reducing the risk of valve displacement caused by normal cardiac contractions. By using the existing left ventricular guidewire, this technique may eliminate the need for additional venous access and right ventricular pacing catheter placement, potentially reducing vascular complications, procedural time, and equipment requirements.
Left ventricular guidewire pacing has become an increasingly utilized technique in modern TAVR procedures, supporting a more streamlined and minimally invasive approach. Its ability to provide effective rapid pacing while reducing the need for additional instrumentation makes it a valuable advancement in structural heart interventions.
