Tricuspid Valve Replacement Using the Right Atrial Appendage Valve: Techniques and 1-Year Results.

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
objectivesWhen tricuspid valve repair is unfeasible due to extensive damage or a complex congenital malformation, surgeons consider tricuspid valve replacement (TVR). However, it is still controversial and challenging to choose the best substitute. We aimed to introduce the innovative intraoperatively valve construction using the native right atrial appendage (RAA) tissue for TVR and investigate the short-term outcomes.
methodsThis study recruited paediatric and adult patients with unrepairable severe tricuspid regurgitation (TR) who needed TVR. The patient's RAA tissue was harvested and used to reconstruct a native bileaflet valve during surgery. Transthoracic echocardiography was conducted before operation, 6, and 12 months after surgery.
resultsThe procedure was successfully executed on 3 patients with valve destruction as a result of infective endocarditis, and 3 patients who had severe TR due to congenital anomalies. There was no mortality or related morbidity. All the constructed valves had proper function with no complications after the surgery. Follow-up echocardiographic studies showed stable and satisfactory valve function with no regurgitation or significant stenosis.
conclusionsThe novel tricuspid valve operation using native RAA tissue demonstrates promising short-term results. Further studies with larger cohorts and longer follow-ups are required to confirm the technique's reliability and long-term effectiveness.
