The aim of this study is to determine whether a left ventricular rapid pacing using the valve delivery guide-wire in TAVI reduces the overall procedure duration in comparison with conventional method. Use of a temporary pacing via a right ventricular lead is still mandatory:

– to provide rapid-pacing;

– for safety reasons in instances of conductance disturbances.

This requires an additional venous access and a pacing catheter which are both likely to generate complications such as:

– Vascular bleedings or tamponades;

– Extra procedural time and radiation exposure.

This randomized study aims at comparing this standard technique to a new technique of stimulation and rapid pacing provided through the valve delivery backup wire inserted in the LV using two alligator clamps: one (the anode) attached to the subcutaneous tissue at the femoral entry site, the other (the cathode) attached to the delivery guide wire: 300 patients included. In 10 high volume TAVI centers (Figure 1). Complete study results will be available by next September. This study should demonstrate whether: the delivery wire rapid-pacing technique is faster than standard RV rapid-pacing technique. It is as safe and efficient as the standard technique. This technique is more cost-effective.
