NCT07607093

Brief Summary

Atrial fibrillation is frequently accompanied by tricuspid regurgitation and may contribute to right atrial and tricuspid annular remodeling, leading to progression of tricuspid regurgitation and adverse clinical outcomes. However, whether early rhythm control improves prognosis in patients with atrial fibrillation and tricuspid regurgitation remains unclear. This study will compare early rhythm control with usual care in these patients, using a composite outcome of cardiac death, heart failure admission, stroke, and tricuspid valve surgery.

Outcome Measures

Primary Outcomes (1)

  • A composite of cardiac death, hospitalization for heart failure, stroke, and tricuspid valve surgery

    The incidence rate of the major clinical events Major clinical event is; 1. Cardiac death Death attributable to cardiac causes, including heart failure, myocardial infarction, fatal arrhythmia, sudden cardiac death, or other cardiovascular causes. 2. Hospitalization for heart failure Hospital admission due to worsening signs or symptoms of heart failure requiring medical treatment, including intravenous diuretics, inotropes, vasodilators, or other heart failure-directed therapy. 3. Stroke A new neurological deficit of presumed vascular origin, including ischemic or hemorrhagic stroke, confirmed by clinical evaluation and/or brain imaging. 4. Tricuspid valve surgery Surgical or transcatheter intervention for tricuspid valve disease, including tricuspid valve repair or replacement.

    From January 1, 2013 to December 31, 2023

Secondary Outcomes (6)

  • All cause death

    From January 1, 2013 to December 31, 2023

  • Cardiac death

    From January 1, 2013 to December 31, 2023

  • Hospitalization for heart failure

    From January 1, 2013 to December 31, 2023

  • Stroke

    From January 1, 2013 to December 31, 2023

  • Tricuspid valve surgery

    From January 1, 2013 to December 31, 2023

  • +1 more secondary outcomes

Study Arms (2)

early rhythm control group

Patients who received rhythm control therapy(include catheter ablation, cardioversion, anti-arrhythmic drugs) within 2 years of new-onset atrial fibrillation

Drug: Anti-arrhythmic drugs for rhythm controlProcedure: DC cardioversion, catheter ablation for rhythm control

Usual care group

Patients who received usual care include rate control therapy without early rhythm control intervention within 2 years of new-onset atrial fibrillation

Other: Usual care

Interventions

flecainide, propafenone, pilsicainide, sotalol, amiodarone, dronedarone

early rhythm control group

Direct-current cardioversion may be performed to acutely restore sinus rhythm, particularly in patients with persistent atrial fibrillation or symptomatic rhythm deterioration. Catheter ablation may be considered as a more definitive rhythm-control strategy to reduce atrial fibrillation burden and maintain sinus rhythm over the long term.

early rhythm control group

General management without atrial fibrillation rhythm control treatment.(Observation without additional medication, or heart rate control treatment if necessary)

Usual care group

Sampling MethodNon-Probability Sample
Study Population

The investigator emulated a sequential target trial comparing early rhythm control with usual care among patients with atrial fibrillation and tricuspid regurgitation, using data from the Korean National Health Insurance Service (K-NHIS) claims database. The K-NHIS database represents the entire population of Korea. The K-NHIS database covers the total population of Korea. The NHIS database includes information on all individuals in Korea, such as demographics, diagnosis codes based on the International Classification of Diseases, 10th Revision (ICD-10), procedures, prescriptions (coded by ATC codes), utilization of healthcare services, and mortality linked to national statistics. The investigator further linked these data with the National Health Screening Program, which provides biennial standardized health examination results, including laboratory measurements such as serum creatinine and hemoglobin, using anonymized individual identifiers.

You may qualify if:

  • Patients with concomitant atrial fibrillation and tricuspid regurgitation.

You may not qualify if:

  • Patients with a history of valvular surgery
  • Patients with congenital heart disease
  • Patients with primary pulmonary hypertension
  • Patients with CIED implantation prior to the diagnosis of tricuspid regurgitation
  • Patients diagnosed with TR only after the initiation of rhythm control therapy for AF
