Questions to Ask Dr. Parikshit Sharma about LBBAP if You Have a Leadless Pacemaker
This guide helps you make the most of your next consultation with Dr. Sharma by focusing on relevant aspects of left bundle branch area pacing (LBBAP) when you already have a unicameral leadless pacemaker.
1. Clinical Indication & Benefit
Would adding or converting to LBBAP provide any clinical advantage over my current leadless pacemaker?
In my case (ventricular-only pacing), what symptoms or ECG changes would suggest I need a more physiologic pacing system like LBBAP?
How do you decide between upgrading a patient to LBBAP versus leaving the leadless pacemaker alone?
2. Device Integration & Feasibility
Is it technically feasible to combine my current unicameral leadless pacemaker with an LBBAP lead for true resynchronization?
Would that require extraction, or can LBBAP be added as a hybrid system?
Are there ongoing trials combining leadless pacing with conduction-system pacing (for example, Aveir VR + LBBAP)?
3. Long-Term Device Management
If my pacing needs increase (e.g., atrial or AV block develops), would you recommend LBBAP instead of a dual-chamber leadless system?
How do you monitor capture thresholds and lead performance in LBBAP compared with leadless pacing?
What are the risks of lead revision or extraction with LBBAP compared to my current system?
4. Electrical Synchrony & Heart Function
What indicators (QRS duration, drop in LVEF, dyssynchrony) would make you consider LBBAP for a patient already paced with a leadless device?
How do pacing-induced dyssynchrony and potential heart-failure risk differ between leadless RV pacing and LBBAP?
Could conduction-system pacing reverse pacing-induced cardiomyopathy if it develops?
5. Programming & Follow-Up
How is LBBAP programmed differently from conventional RV pacing in terms of pulse width, amplitude, and sensing?
Can remote monitoring detect early loss of conduction-system capture?
What kind of follow-up schedule would you recommend for patients with LBBAP?
6. Future Developments
Are there upcoming leadless systems that combine atrial sensing and LBBAP in a single platform?
How close are we to a fully leadless conduction-system pacing solution?
If I ever require cardiac resynchronization therapy (CRT), would LBBAP be preferred over a coronary-sinus lead?
