Pacing Over the Guidewire in Cardiac Structural Intervention: A Practical Guide.

Area of Science:

• Cardiology
• Interventional Cardiology
• Cardiac Electrophysiology

Background:

• Left ventricular (LV) access is crucial for aortic valve interventions, enabling device deployment.
• Temporary cardiac pacing is essential for managing device positioning and deployment during these procedures.
• Traditional temporary right ventricular pacing requires venous access, which can be challenging in some patients.

Purpose of the Study:

• To describe the technique of left ventricular pacing via guidewire for aortic valve interventions.
• To highlight the safety and efficacy of LV pacing as an alternative to RV pacing.
• To provide practical guidance on safe implementation and potential pitfalls.

Main Methods:

• Utilizing guidewire access through the left ventricle for temporary pacing.
• Implementing rapid pacing for device positioning and deployment during transcatheter aortic valve procedures.
• Outlining essential knowledge and experience required for temporary cardiac pacing.

Main Results:

• Left ventricular pacing obviates the need for venous access, simplifying the procedure.
• LV pacing is a safe alternative to temporary right ventricular pacing.
• The technique requires specific procedural knowledge and experience.

Conclusions:

• Left ventricular pacing is a viable and safe alternative for temporary pacing during aortic valve interventions.
• This technique streamlines procedures by eliminating the need for venous access.
• Understanding practical steps and potential pitfalls is key to successful implementation.
