Evaluation and Validation of Management Strategy for Conductive Disorders After TAVR (EVATAVI)

Sponsor: University Hospital, Montpellier

Summary

Considering decrease of major complications and improvement of procedural results, conductive disorders currently remain the main issue after TAVR (Transcatheter aortic valve replacement). While pacemaker implantation rate was about 10-15%, new onset LBBB (Left bundle branch block) was observed in 30 % of patients after TAVR but resolved at discharge in the majority of them, with less than 20% progressed to complete AV (atrioventricular) block requiring permanent pacing at hospital discharge. Higher implantation and improvement of the devices were associated with decline of pace maker implantation rate over the years in experienced teams. While guidelines do not give definite recommendation regarding conductive disorder management and pacemaker indication, a strategy of selective telemetry monitoring (TM) after TAVR according to the risk of conductive disorders may be proposed to limit indication and lenght of stay of intensive care unit admission (ICU), allowing direct admission of lower risk patients in general cardiology ward (GCW) without TM, to decrease the duration of TM when a conductive disorder is stable or regressive and finally to decrease the rate of pacemakers implantation. Potential benefit may also include limitation of ICU overload in high volume TAVR centers, investigators can also expect shorter hospitalization duration, with potential economic impact, in line with the development of algorithms for fast track procedures. Therefore the main objective of our prospective study was to evaluate feasibility and safety of a strategy of management of conductive disorders after TAVR based on an algorithm of diagnosis, monitoring and therapeutic strategies based on ECG analysis.
