Features and short-term outcomes of real-world transcatheter tricuspid valve repair
Article in Annals of cardiothoracic surgery, 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
Background: Transcatheter therapies for tricuspid regurgitation (TR), including tricuspid transcatheter edge-to-edge repair (T-TEER) and transcatheter tricuspid valve replacement (TTVR), have shown promising safety and efficacy in clinical trials. However, real-world data in the Asia-Pacific (APAC) region remain limited. This descriptive study evaluates the clinical characteristics, procedural details, and 30-day outcomes of T-TEER and TTVR in patients with severe TR in the APAC region. Methods: A retrospective analysis was conducted on 174 patients with severe symptomatic TR treated between 2017 and 2025 at four centers in Hong Kong, Taiwan, and Thailand. Patients underwent T-TEER or TTVR (heterotopic or orthotopic). The primary outcome was TR reduction to ≤ moderate at 30 days. Secondary outcomes included procedural complications, adverse events, reinterventions, and symptom improvement. Results: Of the total cohort, 136 patients underwent T-TEER and 38 underwent TTVR. The TTVR group had more severe TR [median effective regurgitant orifice (ERO) area: 0.85 Conclusions: In the APAC region, TTVR is primarily reserved for patients with unfavorable anatomy for T-TEER. Both interventions improve TR and symptoms, but TTVR carries higher procedural risks and longer hospitalization. This comparison was exploratory and hypothesis-generating. These findings emphasize regional practice patterns and the need for long-term comparative studies to optimize treatment strategies.
