[Left ventricular guidewire pacing during transcatheter aortic valve replacement]

Area of Science:

• Cardiology
• Interventional Cardiology
• Cardiac Surgery

Background:

• Transcatheter aortic valve replacement (TAVR) is a crucial procedure for aortic stenosis.
• Ensuring procedural safety and efficacy during TAVR is paramount.
• Alternative pacing strategies are continuously being explored to optimize TAVR outcomes.

Purpose of the Study:

• To evaluate the safety and effectiveness of using left ventricular guidewire pacing during TAVR.
• To assess hemodynamic stability and procedural success with this pacing method.
• To determine the incidence of adverse events associated with left ventricular guidewire pacing in TAVR.

Main Methods:

• Retrospective analysis of 13 patients undergoing TAVR with left ventricular guidewire pacing.
• Collection of clinical and procedural data, including blood pressure and ECG monitoring.
• Post-procedure assessment included aortography for valve regurgitation and follow-up for major adverse cardiac events.

Main Results:

• Successful TAVR was achieved in all 13 patients using left ventricular guidewire pacing.
• Hemodynamic stability was maintained during balloon dilation with pacing.
• No major adverse cardiac events (death, MI, stroke) were observed during hospitalization or at 3-month follow-up.

Conclusions:

• Left ventricular guidewire pacing is a safe and effective strategy for TAVR.
• This pacing method facilitates smooth valve implantation and stable positioning.
• The technique shows promise for improving TAVR procedural outcomes.
