Implication

Trans-tricuspid leads were associated with TR worsening; leaves open whether alternative placements reduce progression.

Structured PICO

Does trans-tricuspid placement of PPM, ICD, or CRT leads worsen tricuspid regurgitation and right-sided heart functions?

Population

41 patients (mean age 63.6 ± 12.2 years, 75.6% male) undergoing trans-tricuspid placement of permanent pacemaker (PPM), implantable cardioverter defibrillator (ICD), or cardiac resynchronization therapy (CRT) leads. Excluded: severe stenosis or regurgitation in atrioventricular or semilunar valves and a history of previous tricuspid valve repair.

Intervention

Trans-tricuspid placement of permanent pacemaker (PPM), implantable cardioverter defibrillator (ICD), or cardiac resynchronization therapy (CRT) leads.

Outcome

Effect on tricuspid valve and right-sided heart functions (tricuspid regurgitation severity, vena contracta, proximal isovelocity surface area, right ventricular dimensions, and right atrial volumes) evaluated by two-dimensional echocardiography at 1st, 6th, and 12th months.surrogate

Trans-tricuspid placement of cardiac device leads is associated with significant progressive worsening of tricuspid regurgitation and right ventricular dimensions over 12 months.

Limitations

Use of 2D echocardiography instead of 3D echocardiography
Small sample size not large enough to determine effect of TR worsening on cardiovascular survival
Single center study
Mostly included patients with decreased LV functions
