Real-world experience utilizing the nuvision 4D intracardiac echocardiography catheter for left atrial appendage closure.
Observational study in Scientific reports, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 8 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
Transesophageal echocardiography (TEE) has been the preferred imaging modality to help guide left atrial appendage closure. Newer technologies such as the Nuvision 4D Intracardiac echocardiography (ICE) catheter allow for real-time 3D imaging of cardiac anatomy. There are no direct comparison studies for procedural imaging between TEE and 4D ICE. To evaluate the performance and safety of left atrial appendage (LAA) closure procedures with the Watchman FLX and Amulet, guided by the Nuvision 4D ICE Catheter. This retrospective observational analysis was conducted on institutional LAAO National Cardiovascular Data Registry from January 2022 to March 2023. Patients had undergone LAA closure procedures with the Watchman FLX or Amulet device guided by TEE or a 4D ICE Catheter. The primary outcome evaluated was successful LAAO device placement. A total of 121 patients underwent LAAO device placement with 46 (38.0%) patients guided by 4D ICE during LAAO implantation. The 4D ICE group had a shorter procedural time compared with TEE guidance. Post procedural 45-day TEE post implant was also comparable for both groups with no patients in either group having incomplete closure of the left atrial appendage and peri-device leak > 5 mm. No device related complications (device related access, stroke, or pericardial effusion) occurred in either group at follow-up. There was no significant difference in device implant success or post procedural outcomes at 45 days in either the TEE or 4D ICE group. However, there was a noticeable improvement in procedural time with the 4D ICE catheter.
