Cardiac Amyloidosis With Right Atrial Appendage Thrombus Detected After Left Atrial Appendage Occlusion.

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
backgroundLeft atrial appendage occlusion (LAAO) is a valuable alternative therapy to anticoagulants for stroke prevention, and a representative study has demonstrated a high rate of anticoagulant discontinuation after LAAO. CASE SUMMARY: LAAO was performed on an 88-year-old woman with cardiac amyloidosis (CA). Although anticoagulant therapy was discontinued after LAAO, a follow-up image showed a thrombus in the right atrial appendage (RAA) incidentally. Anticoagulation was resumed, and no clinical events were detected during a 1-year follow-up. DISCUSSION: Although LAAO is an effective treatment for stroke prevention in patients with CA, this condition is associated with an increased risk of intracardiac thrombus. Therefore, discontinuation of anticoagulant therapy after LAAO should be approached by keeping in mind the possibility of RAA thrombus. TAKE-HOME MESSAGES: LAAO can be effective in CA, yet anticoagulation discontinuation must be individualized, keeping in mind the possibility of RAA thrombus in high-risk patients.
