Outcomes of Intracardiac Echocardiography as the Primary Imaging Modality for Transcatheter Tricuspid Valve Procedures.
Article in Structural heart : the journal of the Heart Team, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled it.
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: Tricuspid regurgitation (TR) is a high-mortality condition. While tricuspid transcatheter edge-to-edge repair (T-TEER) and transcatheter tricuspid valve replacement (TTVR) improve quality of life, their reliance on transesophageal echocardiography (TEE) poses challenges. Intracardiac echocardiography (ICE) offers a promising adjunct; however, data on safety and efficacy remain limited. This study evaluates procedural characteristics, safety, and outcomes as operators gain experience with ICE for tricuspid procedures. Methods: Twenty-two patients with symptomatic ≥ severe TR treated with TTVR or T-TEER at Oregon Health & Science University were enrolled. All procedures utilized ICE and TEE. Patients were divided into 2 cohorts: cohort 1 primarily used TEE with adjunctive ICE (10 cases: 4 TTVRs and 6 T-TEERs), while cohort 2 primarily used ICE with adjunctive TEE (12 cases: 5 TTVRs and 7 T-TEERs). Procedural characteristics and outcomes were compared. Results: Mean TTVR procedure time decreased from 124 ± 38 minutes in cohort 1 to 98 ± 36 minutes in cohort 2, while T-TEER times dropped from 115 ± 35 minutes to 108 ± 30 minutes. Fluoroscopy time decreased from 27 ± 10 minutes to 19 ± 9 minutes for TTVRs and from 27 ± 11 minutes to 25 ± 10 minutes for T-TEERs. The TR grade was reduced by ≥ 2 grades in all but 1 patient with no mortality, bleeding events, or hospitalizations across all cohorts. Conclusions: Primary ICE strategy improves procedural efficiency while maintaining comparable safety and efficacy. Larger studies are needed to confirm these findings, as only 22 patients participated in this study, limiting statistical robustness.
