Transcatheter Tricuspid Valve Replacement Versus Totally Thoracoscopic Beating-Heart Surgery for Tricuspid Regurgitation.
Article in Cardiovascular drugs and therapy, 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
purposeTotally thoracoscopic and beating-heart techniques used in tricuspid valve surgery (TTC-TVS) show favorable outcomes. Transcatheter tricuspid valve replacement (TTVR) is an increasingly utilized alternative for patients with tricuspid regurgitation (TR) at high surgical risk. The purpose of this study was to compare TTVR with TTC-TVS to examine the outcomes of these two different management protocols for patients with symptomatic severe TR.
methodsA total of 116 patients with symptomatic severe TR were retrospectively collected and divided into the TTVR (n = 38) and the TTC-TVS (n = 78) groups. The primary end points included 2-year all-cause mortality and the combined endpoint (all-cause mortality and hospitalizations for heart failure).
resultsAt a median follow-up of 630 (IQR 450-720) days, the similar freedom from 2-year all-cause mortality (85.2% vs. 70.8%; log-rank P = 0.13) and different freedom from combined endpoint (75.3% vs. 49.8%; log-rank P = 0.0049) were followed in TTVR and TTC-TVS. After stratification by TRI-SCORE, TTVR subgroups showed significant difference in combined endpoint, and both also showed significant difference compared to the corresponding TTC-TVS subgroups (all log-rank P < 0.05). In multivariate Cox regression analysis, TRI-SCORE ≥ 6 was independently correlated with all-cause mortality (HR 3.913, 95% CI 1.481-10.337; P = 0.006) and combined endpoint (HR 4.070, 95% CI 1.924-8.608; P < 0.001).
conclusionsTTVR may offer greater benefit compared to TTC-TVS for sicker patients with severe TR. However, this observation should be interpreted within a specific clinical context emphasizing the importance of early intervention.
