Trial Outcomes & Findings for Dipole Density Mapping in Supraventricular Tachycardia (NCT NCT02469623)

NCT ID: NCT02469623

Last Updated: 2019-09-18

Results Overview

Sites reported all adverse events throughout the study follow-up period regardless of their relationship to the device or procedure. Each event was classified and adjudicated by the site-specific investigator. The data were further analyzed by the Sponsor medical reviewer, providing a consistent determination of relationship to device, procedure and the subjects' underlying disease of the atrial arrhythmia condition.

PRIMARY outcome

Timeframe: 1 day

Population: The study population consists of men and women between the ages of 18 - 75 years of age scheduled for an endocardial ablation for a supraventricular tachycardia (SVT)

The primary performance endpoint was the number of subjects with successful construction of pre- and post-ablation procedure activation maps.
