What happens to the tricuspid valve in atrial fibrillation patients without strong valve leakage

Official title: Natural History of Atrial Fibrillation-Induced Tricuspid Valve Remodeling in the Absence of Significant Tricuspid Regurgitation: A Three-Dimensional Echocardiographic Study (TRICUSPID-AF)

Run by Centro Cardiologico Monzino · NCT07617974 · Data updated 2026-11-12

This study looks at how the tricuspid valve changes over a year in people with atrial fibrillation who don’t have significant valve leakage, using 3D heart imaging.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults with paroxysmal or persistent AF undergoing TTE before AF ablation and who can undergo 3D TV imaging.

Probably not a fit

Patients with significant existing TR or poor image quality may not benefit from the findings.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This multicenter, prospective observational study will follow adults with atrial fibrillation undergoing baseline and 1-year follow-up echocardiography. Researchers will measure tricuspid valve geometry with 3D imaging and AI-assisted analysis, alongside standard echo metrics and right heart strain, while tracking AF burden with Holter monitoring at baseline, 3 months, and 12 months. The primary goal is to compare 3D tricuspid annulus geometry between paroxysmal and persistent AF, and secondary goals include changes over time, development of moderate or greater TR, and relationships between AF burden and remodeling. Results will be contextualized against two control groups: structurally normal hearts without AF, and AF patients with moderate atrial functional TR but no significant left-sided disease or prior valve intervention. The study will help clarify whether AF type and burden drive tricuspid remodeling even when significant TR is not present.

Why it matters

Potential benefit: If successful, the study could improve understanding of early tricuspid remodeling in AF, potentially informing earlier monitoring or interventions.

How similar studies have gone: Prior similar work has explored AF-related atrial and valvular remodeling, but this study adds AI-powered 3D quantification and head-to-head AF burden analysis in a prospective design.

Who can join: the full rules

Show full inclusion / exclusion criteria
Inclusion Criteria:

* Consecutive patients with atrial fibrillation (paroxysmal or persistent) undergoing transthoracic echocardiography (TTE) prior to AF ablation with acquisition of a 3D TV dataset.

Eligible for enrollment in the control group will be:

1. all consecutive patients with structurally normal hearts and no history of AF or;
2. moderate atrial functional tricuspid regurgitation and AF, in the absence of significant left-sided valvular disease or prior valvular surgery.

Exclusion Criteria:

* Moderate or greater TR assessed using a multiparametric approach;
* Arrhythmias other than AF;
* Prior AF ablations;
* Rapid ventricular response (average HR \>110 bpm) during baseline TTE;
* Inadequate image quality
