Study summary

The main objective of the study is to demonstrate that prophylactic treatment of patients with asymptomatic frequent (>10%) PVCs is superior to simple follow-up strategy with no therapy to prevent subsequent LV dysfunction at 24 months. The prophylactic treatment is based on drugs ± ablation (ablation can be performed if the PVC burden remain >10% after 2 lines of AAD treatment since the initiation of the study).

The primary endpoint will be the development of LV dysfunction (PVC-iCMP) defined as a 15% relative LVEF decrease (and/or a LVEF \<50%) within 2 years following randomization, on cardiac magnetic resonance imaging (cMRI) (or transthoracic echocardiography (TTE) when not possible).

Read the detailed description

Premature ventricular contractions (PVCs) are frequently encountered in clinical practice, in the setting of underlying heart disease as well as in "normal" hearts. Frequent PVCs have been shown to impact long term prognosis in patients with structurally normal hearts,[1] as well as in documented cardiomyopathy. In both settings, PVCs may cause symptoms and, in rare cases, sudden cardiac death. For about two decades, it has been accepted that frequent PVCs may also induce left ventricular (LV) dysfunction called PVC-induced cardiomyopathy (PVC-iCMP). Indeed, PVC suppression by using drugs or catheter ablation has been associated with full recovery of left ventricular dysfunction.[2-4] De facto, PVC-iCMP diagnosis as well as identification of predictors has always been established retrospectively. Therefore, risk stratification or simply knowing the exact incidence of the disease in exposed patients remain difficult.

European and US guidelines recommend to treat symptomatic PVC patients regardless of the burden or their risk profile, as well as "frequent PVCs" associated with LV dysfunction (Experts tend to consider worthwhile treating for burden >10%, which was the lowest burden associated with PVC-iCMP).

However, there is no clear recommendation for asymptomatic patients exposed to very frequent PVCs, at risk of developing cardiomyopathy. As no previous studies included such population, expert suggested that these patients should be at least closely followed. Consequently, management of such patients is widely heterogeneous.

The hypothesis of this study is that prophylactic suppression of very frequent PVCs (>10%) will prevent or significantly reduce the incidence of PVC-iCMP.

Eligibility criteria

Inclusion Criteria:

Inclusion criteria (all must be present):

  1. 18 ≤ Age ≤ 85
  2. PVC burden ≥ to 10% regardless of current or preexisting antiarrhythmic drug intake (for instance, a patient under betablocker therapy because of his PVCs or hypertension can be included)
  3. Asymptomatic status
  4. Normal (>or= 55%) . Patients with underlying cardiomyopathy can be included as long as LV function remains preserved.
  5. Signed

Exclusion criteria (any of them):

  1. Pregnant woman or Female of without effective method of or nursing woman.
  2. Patients that can't undergo MRI study
  3. De novo requirement for antiarrhythmic drug prescription for another indication (e.g. atrial fibrillation...)
  4. The physician already decided that the patient requires drug initiation or escalation;
  5. Ischemic cardiomyopathy requiring revascularization (PCI or surgery)
  6. History of LV dysfunction
  7. Participation in another research involving the human person
  8. Patient under legal protection
  9. Non affiliation to a social security scheme
Terms in these criteria, in plain language(4)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

LVEF (left ventricular ejection fraction)

The share of blood the heart’s main pumping chamber (the left ventricle) pushes out with each beat, measured by an echocardiogram (heart ultrasound) or a MUGA scan. About 50–70% is normal.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Childbearing potential

Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).

Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

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 6, 2023, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
