Ambulant Monitoring to Detect Hemodynamic and Electrical Impact of Severe Tricuspid Valve Regurgitation

This exploratory study aims to study the feasibility to detect early signs of disease progression in patients with severe TVR (grade ≥3/4) by monitoring electrical cardiac activity and correlating it with echocardiographic findings. The Byteflies monitoring device will be used for continuous 14-day outpatient ECG tracking. Transthoracic echocardiography will assess structural and pressure changes in the heart and liver. The goal is to improve early detection of right heart failure and hepatic congestion.

  • Normal sinus rhythm
  • Dutch speaking

Exclusion criteria

Treatment and study plan

14 days ambulatory rhythm monitoring

Diagnostic Test

14 days ambulatory rhythm monitoring using Byteflies

Primary outcomes

  1. Atrial electrical instability

    Time frame: 14 days

    Burden (expressed in % of total number of beats) of isolated atrial extrasystoles, runs of atrial tachycardie (less than 30 seconds), and sustained atrial arrhythmia (lasting 30 seconds or longer). These findings will be correlated with echocardopgrahic measurements to detect electrical markers associated with the severity of tricuspid valve regurgitation.

  2. Ventricular electrical instability

    Time frame: 14 days

    Burden (expressed in % of total number of beats) of isolated ventricular extrasystoles, runs of ventricular tachycardie (less than 30 seconds), and sustained ventricular arrhythmia (lasting 30 seconds or longer). These findings will be correlated with echocardopgrahic measurements to detect electrical markers associated with the severity of tricuspid valve regurgitation.

Secondary outcomes

  1. Bradycardia

    Time frame: 14 days

    Prevalence (%) of bradycardia events on 14 day rhythm monitoring defined as any occurence of ventricular rhythms <30 beats per minute or high-degree AV block. These findings will be correlated with echocardopgrahic measurements to detect electrical markers associated with the severity of tricuspid valve regurgitation.

  2. Adverse events associated with rhythm monitoring

    Time frame: 14 days

    Prevalence (%) of any interruption in 14 days rhythm monitoring due to adverse events with the Byteflies monitoring patch (skin rash, allergic reactions,...)
