Extended Rhythm Monitoring to Assess for Ventricular Arrhythmias After Transcatheter Pulmonary Valve Replacement With the Harmony Valve.

ABSTRACT:

Background

Varying rates of nonsustained ventricular tachycardia (NSVT) have been reported early after transcatheter pulmonary valve replacement (TPVR) with the Harmony valve, but data regarding rhythm outcomes beyond hospital discharge are limited. This study aims to characterize ventricular arrhythmias after Harmony TPVR from implant through mid-term follow-up.

Methods

Ventricular arrhythmia data from postimplant telemetry and follow-up extended rhythm monitoring (ERM) were analyzed after Harmony TPVR.

Results

Fifty-four patients with tetralogy of Fallot (n=39), valvar pulmonary stenosis (n=10), or pulmonary atresia with intact ventricular septum (n=5) were studied; 22% had prior NSVT and 24% were on prior rhythm medication. On postimplant telemetry, 27 patients (50
