ABSTRACT
Aims:
To correlate dynamics in electrical conduction after transcatheter aortic valve implantation (TAVI) with need for permanent pacemaker implantation (PPM) and assess implications for early discharge. Methods andresults:
Daily electrocardiograms after TAVI were analysed for rhythm and conduction times and were correlated with PPM. Transcatheter aortic valve implantation was performed in 291 consecutive patients with three contemporary transcatheter heart valve designs Medtronic CoreValve (n = 111), Edwards Sapien XT (n = 29) and Sapien 3 (n = 72), and Boston Lotus (n = 79). We considered two cohorts (A) Patients with normal baseline conduction; and (B) patients with pre-existent conduction disturbances. Based on QRS dynamics, three patterns were discerned stable normal QRS duration, transient QRS prolongation, and persistent QRS prolongation. In Cohort B, QRS dynamics did not correlate with PPM. In contrast, in Cohort A, QRS dynamics and PPM appeared highly correlated. Neither patients with stable normal QRS duration (0/47), nor patients with transient QRS prolongation required PPM (0/26). All PPMs occurred in patients with persistent QRS prolongation until discharge (27/85). Persistent QRS prolongation was typically seen with Lotus and CoreValve, whereas stable normal QRS duration was typically seen with Sapien XT and Sapien 3.Conclusion:
Three distinct patterns of QRS dynamics can be discerned after TAVI and their predictive probabilities for PPM strongly relate to the baseline conduction status. Patients with normal conduction at baseline and stable QRS duration after TAVI are potentially eligible for early discharge.
