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).

Edwards devices placed on the European market meeting the essential requirements referred to in Article 3 of the Medical Device Directive 93/42/EEC bear the CE marking of conformity.

Keywords: aortic bioprostheses; aortic valve replacement; permanent pacemaker implantation; rapid deployment prosthesis

In recent years, rapid deployment and transcatheter valves have reduced the invasiveness of aortic valve replacement. However, both of these types of prosthesis have been associated with conduction disturbances and subsequent postoperative permanent pacemaker implantation (PPI).

This summary highlights key results from a single-centre, observational study assessing the factors associated with PPI following the implantation of EDWARDS INTUITY or EDWARDS INTUITY Elite valves. Arribas et al. analysed data for 71 patients followed up for an average of 33 months, and assessed the incidence, reasons for and impact of PPI.
