Study summary

To assess potential link between unrecognized myocardial inflammation (myocarditis) and premature ventricular contractions (PVCs) associated with and without reduced Left ventricular ejection fraction (LVEF) through comprehensive diagnostic work up.

Read the detailed description

Hypothesized that occult inflammation is clinically under-recognized in patients with symptomatic PVCs with and without Left ventricular (LV) dysfunction and can be a potential link between the 2 conditions. Aimed to evaluate the incidence of underlying inflammation using the Positron emission tomography (PET) scan in patients presenting with symptomatic PVCs enrolled retrospectively in the MAVERIC registry.

What researchers measure

Primary outcomes

  1. Identify the underlying myocarditis in patients presenting with PVCs with or without reduced LVEF

    To identify the underlying myocarditis in patients presenting with PVCs with or without reduced LVEF through laboratory testing, FDG-PET(18F-2-fluoro-2-deoxy-D-glucose fluorodeoxyglucose - positron emission tomography) scan, Cardiac Magnetic Resonance imaging and/or Endomyocardial biopsy.

    Time frame: Retrospective Collection between dates January 2014-January 2023

Secondary outcomes

  1. Ascertain whether immunosuppressive therapy (IST) affords short term and long term improvement of LVEF and clinical outcomes

    Time frame: Retrospective Collection between dates January 2014-January 2023

Other outcomes

  1. Evaluate whether IST + catheter ablation results in optimal clinical response

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Sep 4, 2025, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
