Leadless Pacing for Delayed Heart Block After Transcatheter Tricupid Valve Replacement.
Article in JACC. Case reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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 minimally invasive treatment for severe tricuspid regurgitation. However, atrioventricular block (AVB) requiring permanent pacemaker implantation occurs in 12.0% to 13.3% of patients without a pacemaker. CASE SUMMARY: An 81-year-old man presented 7 days after TTVR with dyspnea and dizziness. Electrocardiography showed alternating AVB, and monitoring indicated a transient episode of complete AVB, suggesting a premonitory sign of delayed conduction disease after EVOQUE implantation. A leadless pacemaker (Micra VR) was implanted to avoid interference with the prosthetic tricuspid valve. The procedure was uneventful, and follow-up showed stable pacemaker parameters and preserved prosthetic valve function. DISCUSSION: This case review summarizes conduction disturbances after TTVR, pacing strategies, and postprocedural monitoring. In the absence of recommendations, pacemaker selection should be individualized, with leadless pacing representing a valve-sparing strategy. TAKE-HOME MESSAGES: Delayed AVB may occur after TTVR, with an alternating AVB as a premonitory sign. Leadless pacemakers offer a valve-sparing pacing option.
