Conduction disturbances following surgical aortic valve replacement with a rapid-deployment bioprosthesis

Keywords: aortic stenosis; aortic valve replacement; bundle branch block; conduction disturbances

Rapid-deployment aortic valve replacement (RD-AVR) may cause conduction disturbances in the heart and lead to permanent pacemaker implantation.  

This real-world, prospective study presents data from 700 consecutive patients, who underwent RD-AVR with an EDWARDS INTUITY valve. Coti et al. analysed postoperative, 3-month and 1-, 3- and 5-year follow-up data to assess the incidence of new conduction disturbances and pacemaker implantation rates. The authors also identified preoperative predictors for new pacemaker requirement. This study highlights how inclusion criteria and concomitant interventions can affect cardiac conductions after RD-AVR.

Important safety information:

Use of the EDWARDS INTUITY Elite valve system may be associated with new or worsened conduction disturbances, which may require a permanent cardiac pacemaker implant (PPI). The rate of PPI for the EDWARDS INTUITY Elite valve is within the range reported in the literature for various rapid deployment valves, but higher than that reported for surgical aortic valves. Physicians should assess the benefits and risks of the EDWARDS INTUITY Elite valve prior to implantation. See instructions for use for additional information.

For professional use. For a listing of indications, contraindications, precautions, warnings, and potential adverse events, please refer to the Instructions for Use (consult eifu.edwards.com where applicable).
