Impact of Residual Transmitral Mean Pressure Gradient on Outcomes After Mitral Transcatheter Edge-to-Edge Repair.
Article in JACC. Advances, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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: There is conflicting evidence regarding the effect of residual transmitral mean pressure gradient (TMPG) after mitral transcatheter edge-to-edge repair (M-TEER). Different TMPG cutoffs have been employed in prior studies with varying results. Objectives: The purpose of this study was to examine the association between residual TMPG and M-TEER outcomes. Methods: Consecutive patients undergoing M-TEER at our institution between 2014 and 2022 were included and divided based on quartiles of predischarge TMPG. Outcomes were assessed using Kaplan-Meier analysis and Cox proportional hazard models. We performed subgroup analyses according to mitral regurgitation (MR) mechanism. The primary outcome was all-cause mortality or heart failure hospitalization. Results: We included 283 patients (age 76.7 ± 10.8 years, 42.8% women, 78.4% Caucasian, and baseline TMPG 2.4 ± 1.3 mm Hg). Higher baseline TMPG was a predictor of increased TMPG after M-TEER (coefficient 0.60 [95% CI: 0.40-0.70]; Conclusions: In this single-center study, higher residual TMPG after M-TEER was associated with worse outcomes at intermediate- to long-term follow-up. The effect was mainly driven by increased mortality especially in patients with primary MR. Operators should strive to lower residual TMPG before the conclusion of the procedure.
