1 · What the graph read from 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.

2 · The registry

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

Intracardiac echocardiography (ICE) is considered an alternative imaging modality for left atrium appendage occlusion (LAAO) to avoid general anesthesia. However, the quality of ICE images obtained from right atrium can be suboptimal compared with transesophageal echocardiography (TEE) imaging. Although placing an ICE probe into left atrium can improve imaging quality, there are limited data regarding procedure outcomes of ICE-guided LAAO versus TEE-guided LAAO. One hundred forty four patients who underwent LAAO with Amplatzer Cardiac Plug, Amulet, or Watchman device were enrolled from two referral institutes. TEE-guided LAAO was performed under general anesthesia or deep sedation (n = 103), and ICE-guided LAAO was conducted under local anesthesia (n = 41). An ICE probe was placed into left superior pulmonary vein (LSPV) via transseptal approach. The procedure success and complication rates of the ICE-guided LAAO were comparable with the TEE-guided LAAO (100 vs. 97.1%, p = 1.0; 2.4 vs. 6.8%, p = 0.734, respectively). The procedure time and total radiation dose were significantly lower in ICE-guided group compared with TEE-guided group (58.0 [55.0, 61.0] min vs. 80.0 [58.0, 95.0] min, p < 0.001; 456.0 [359.0, 604.0] mGy vs. 625.0 [439.0, 1502.5] mGy, p < 0.001, respectively). In multivariate analysis, younger age, the last time period of procedure, and local anesthesia were independent factors affecting shorter procedure time. ICE imaging from the LSPV provided optimal views for LAAO procedure with a significant reduction of total procedure time through performing under local anesthesia. This approach can be very useful for LAAO procedure especially in patients who are ineligible for general anesthesia.
