Safety and Feasibility of Left Bundle Branch Area Pacing Following Transcatheter Tricuspid Valve Replacement.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundTranscatheter tricuspid valve replacement (TTVR) is a novel therapy for severe tricuspid regurgitation. However, conduction disturbances requiring pacemaker implantation occur in up to 24.7% of patients. Left bundle branch area pacing (LBBAP) has not been systematically evaluated post-TTVR, where lead passage across the prosthesis may compromise valve integrity. The objective of this paper was to report the feasibility, safety, and performance of LBBAP after TTVR. CASE SUMMARY: Two pacemaker-naïve patients requiring pacing post-TTVR were retrospectively analyzed. DISCUSSION: Both patients underwent TTVR and developed high-grade atrioventricular block within 72 hours. LBBAP was successful in both cases with no procedural-related complications. At 30 days, pacing parameters remained unchanged with no device-related adverse events. Echocardiography at 1 and 30 days demonstrated ≤ mild tricuspid regurgitation, no lead-valve interaction, and stable right ventricular function. TAKE-HOME MESSAGES: LBBAP post-TTVR is feasible with excellent short-term safety and performance while maintaining valve integrity. Our series reinforces its safety and adds systematic echocardiographic follow-up.
