Robotic-assisted left atrial appendage occlusion: an important complementary option in the surgical management of atrial fibrillation.

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
objectivesThe growing popularity of minimally invasive treatment of atrial fibrillation (AF) has shown increasing interest in concomitant left atrial appendage occlusion (LAAO). Surgical robotic technology adds advantages such as magnified visualization, enhanced dexterity of movement and decreased invasiveness. The aim of this study is to evaluate the effectiveness and early outcomes of robotic-assisted LAAO.
methodsThis is an observational, multicentre, retrospective study of patients with AF who underwent robotic-assisted LAAO. In-hospital mortality, perioperative complications, length of stay (LOS) and imaging-driven (cardiac CT scan, transesophageal echocardiography [TEE]) efficacy at 3-month follow-up were analysed.
resultsBetween August 2019 and June 2024, 194 patients with documented AF (70.4% male, mean age 67.7 ± 10.1) underwent robotic-assisted epicardial LAAO. The procedure was performed under TEE guidance in 193 patients without complications. In one patient with previous sternotomy, LAAO was not feasible. Blood product transfusion was necessary in one patient, due to significant chest wall bleeding requiring thoracoscopic re-exploration. No stroke or thromboembolic events were observed. Left hemidiaphragm paralysis requiring plication occurred in 3 patients (1.5%). Hospital mortality was 0%. Mean LOS time was 2.2 days (range 1-10 days) and all patients were discharged home. Imaging follow-up was complete in 157 cases (81%) and was achieved by TEE in 91 patients while the remaining 66 underwent cardiac CT scan. Two patients had residual flow in the left atrial appendage and oral anticoagulant was continued at follow-up.
conclusionsRobotic-assisted LAAO is safe with satisfactory outcome both in an isolated setting and with concomitant hybrid ablating procedures for patients with AF.
