Index Transcatheter Aortic Valve Expansion After TAV-in-TAV Using a One-Size-Smaller SAPIEN Valve.

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
backgroundIndex transcatheter aortic valve (TAV) expansion during TAV-in-TAV is crucial as it changes the valve-to-aorta distances and may increase the intraprocedural risk. CASE SUMMARY: A TAV-in-TAV procedure was planned for a 90-year-old woman with prior TAV replacement (23-mm SAPIEN XT) who presented with prosthetic valve stenosis. Second TAV sizing was assessed by averaging the stent areas of the index TAV and by drawing a virtual circle on preprocedural computed tomography (CT). CT imaging also revealed significant calcification of the index TAV leaflets. The team opted for a one-size-smaller 20-mm SAPIEN3 valve. During the procedure, the index TAV expanded by creating a gap between the 2 valve stents. Postprocedural CT confirmed index TAV expansion and the calcified leaflets in the gap, which likely facilitated the expansion. DISCUSSION: Our case highlights the importance of considering leaflet calcification of the index TAV when planning TAV-in-TAV, which includes second TAV sizing and predicting index TAV expansion.
