Why the study?
Cardiac arrhythmias are frequently reported after left ventricular assist device implantation, but current literature lacks sufficient information on these arrhythmias.
Does Left Ventricular Assisted Device implantation alter the frequency of ventricular and supraventricular arrhythmias in patients with end-stage heart failure?
Does Left Ventricular Assisted Device implantation alter the frequency of ventricular and supraventricular arrhythmias in patients with end-stage heart failure?
Ventricular and supraventricular arrhythmias remain common after LVAD implantation, though the frequency of sustained ventricular tachyarrhythmias is reduced in the early postoperative phase compared to preoperatively.
Post-LVAD arrhythmia burden remains poorly quantified; this retrospective series leaves open the need for prospective incidence and outcome studies.
Cardiac arrhythmias has been frequently reported after left ventricular assist devices implantation butcurrently literature shows no sufficient information on cardiac arrhythmias. Objective: The aim of thisstudy was to assess the frequency and other features of ventricular and supra ventricular ectopic beats((SVEB), atrial fibrillation (AF)/ flutter (AFL) post device implantation. Methods: This is a retrospectivestudy conducted in Department of Cardiac-Surgery, University of Verona Medical School, Verona, Italyfrom June 2014-September 2016. Rhythm monitoring and registration were collected from 16 patients (13males; 45±13years) during the first five (05) days after implantation. To assess late post-operative rhythm,patient’s hospital electronic records were used as well as functional hemodynamic parameters includingmean arterial pressure (MAP), right atrial pressure (RAP), heart rate (HR) and ST-deviation(d-ST).Results: Ventricular arrhythmia (n=9), atrial fibrillation (n=5) or atrial flutter (n=2) episodes werepreoperatively present in 11 patients. Postoperatively, 5 patients developed either VT (n=2), AF (n=1) orboth VT/AF (n=2) during a follow-up of 18±14 months. Prior to postoperative VT (POVT) episodes (n=123),MAP decreased, HR, d-ST increased and RAP remained unaltered. POVT were initiated either by singleVEBS (28%), V-couplets (15%), V-run (46%) or occurred suddenly (11%). Conclusions: Ventricular andsupraventricular arrhythmias are common after device implantation. The frequency of sustained VTA wasless at early phase as compared to late postoperative phase.
