Tricuspid regurgitation (incompetence) is not only common in the elderly (affecting ~37% of over-80s), but it also critically influences the choice of pacing modality. When considering Left Bundle Branch Area Pacing (LBBAP), the pre‑existing TR grade, mechanism, and lead type must be carefully weighed. Below is a synthesis of current evidence.
📋 impact of LBBAP on TR: what studies show
Recent data present two opposing patterns — worsening vs. improvement — depending on patient profile. The table below summarises key findings.
| Study focus / comparison | Key finding | Clinical implication |
|---|---|---|
| LBBAP vs. traditional right ventricular pacing (RVP) | LBBAP associated with 2.59‑fold increased risk of significant TR worsening over 2‑year follow‑up. | Raises caution: not all elderly patients benefit; those with mild TR might progress if lead interferes with valve. |
| Pre‑existing moderate‑to‑severe TR or atrial fibrillation | LBBAP led to significant improvement in TR grade. | In this subgroup, LBBAP may be preferred because resynchronisation reduces functional TR. |
| LBBAP vs. biventricular pacing (BVP) for CRT‑D | LBBAP caused significant worsening of TR compared to BVP (defibrillator leads larger, two leads across valve). | For CRT‑D candidates, BVP (or leadless) might be safer if TR is a concern. |
| His‑bundle pacing (HBP) as alternative | Expert guidelines: HBP may be preferred over LBBAP in patients with tricuspid dysfunction or prior repair. | Directly informs decision: when valve preservation is paramount, HBP is evidence‑based. |
🧐 decision‑making factors in elderly with TR
Before implanting LBBAP, the electrophysiologist and heart team evaluate:
- 🔹 Severity and mechanism: mild/stable? Or moderate/severe secondary to atrial fibrillation? (AF‑related TR often improves with LBBAP).
- 🔹 Pacing indication: bradycardia vs. cardiac resynchronisation (CRT‑D leads are larger, risk higher).
- 🔹 Lead type and implant technique: distance from leaflet to screw site (E‑T distance) is critical; shorter distance = higher TR risk.
- 🔹 Alternative pacing options: leadless pacemaker (no valve trauma) or His‑bundle pacing (valve‑sparing).
📌 bottom line for the elderly patient:
If TR is mild and asymptomatic, LBBAP may still be used with careful lead positioning. If TR is moderate‑to‑severe (especially with atrial fibrillation), LBBAP could improve it — but only after ruling out primary leaflet disease. In complex cases (prior valve surgery, defibrillator needed), leadless pacing or HBP should be discussed.
💡 alternative pacing strategies (valve‑sparing)
✔️ Leadless pacemaker – entirely avoids tricuspid apparatus; studies show trend toward less TR worsening. Ideal for elderly with significant TR and standard bradycardia indication.
✔️ His‑Bundle Pacing (HBP) – physiological, and expert consensus recommends it may be preferred over LBBAP in presence of tricuspid dysfunction, prosthesis, or prior transcatheter repair.
✔️ Biventricular pacing (BVP) – still a reasonable CRT option, especially if a defibrillator is needed, as it avoids an extra lead through the valve (compared to LBBAP+ICD).
In conclusion, tricuspid incompetence is never irrelevant when planning LBBAP — it shapes the risk/benefit calculus. A personalised approach, combining echocardiography, symptom assessment, and up‑to‑date evidence (as referenced above), ensures the best outcome for elderly patients.
