3D Transthoracic Echocardiographic Evaluation on Tricuspid Regurgitation Progression and Clinical Outcomes in Patients With Cardiac Implantable Electronic Device (3DECHO-TR)

26. august 2026 oppdatert av: Juwon Kim, Samsung Medical Center

The goal of this observational study is to learn about the development and worsening of tricuspid regurgitation (TR) in patients who have cardiac implantable electronic devices (CIEDs).

The main objective is to compare left bundle branch area pacing (LBBaP) and leadless pacemakers against conventional pacemakers in terms of TR exacerbation.

Participants with these devices will have their retrospective and prospective clinical data analyzed and will undergo 3D transthoracic echocardiography to identify the exact mechanical causes of TR.

Detaljert beskrivelse

As the use of cardiac implantable electronic devices(CIED) increases, CIED-related tricuspid regurgitation (CIED-related TR) is emerging as a critical clinical issue. CIED-related TR is one of the most common causes of primary TR, with a reported incidence ranging from approximately 10% to 30%. Numerous studies have confirmed that the severity of CIED-related TR is closely associated with poor prognosis.

This condition is particularly noteworthy because, unlike secondary TR, it possesses mechanical causes that are potentially intervenable. However, most studies published to date have reported results based on 2D echocardiography, which often leads to ambiguity in identifying the exact mechanisms behind the exacerbation of tricuspid regurgitation. Furthermore, there is a significant lack of data regarding TR associated with more recently introduced procedures, such as left bundle branch area pacing (LBBaP) and leadless pacemakers. Therefore, this study aims to perform 3D transthoracic echocardiography on patients with lead-based CIEDs and leadless pacemakers to comparatively analyze LBBaP and leadless pacemaker patients against conventional pacemaker patients in terms of TR exacerbation. By combining retrospective and prospective clinical data, this research will analyze the incidence and clinical impact of these conditions.

Studiepopulasjon

Subjects aged 19 years or older who underwent de novo implantation of a leadless PPM or a cardiac implantable electronic device (PPM or ICD) with trans-tricuspid leads at Samsung Medical Center between 2022 and 2025, and are at least one year post-implantation

Beskrivelse

Inclusion Criteria:

  • Aged 19 years or older.
  • Patients who are at least one year post-implantation of one of the following Cardiac Implantable Electronic Devices (CIEDs):

A. Permanent Pacemaker (PPM) B. Implantable Cardioverter-Defibrillator (ICD) C. Leadless Pacemaker

  • Patients who underwent the implantation procedure on or after January 2022.
  • Voluntary informed consent provided by the patient or their legal representative for the review of medical records and study-related data throughout the entire study period.

Exclusion Criteria:

  • Patients with lead-based CIEDs whose leads do not cross the tricuspid annulus or those with two or more leads crossing the annulus.
  • Patients whose baseline degree of tricuspid regurgitation (TR) cannot be assessed due to the absence of transthoracic echocardiography (TTE) performed within three months of the procedure.
  • Patients with a history of ventricular lead extraction.
  • Patients who have undergone tricuspid valve replacement surgery.
  • Individuals who refuse active medical treatment.
