Frozen Leaflet During Transcatheter Balloon-Expandable Aortic Valve Implantation: Early Recognition and Safe Management.

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
backgroundThe occurrence of frozen or stuck leaflet during transcatheter aortic valve implantation (TAVI) is a rare but potentially fatal complication. CASE SUMMARY: An 83-year-old man was referred to an Italian Cardiology Unit for symptomatic severe aortic stenosis. The patient underwent transfemoral TAVI with a 26-mm Myval balloon-expandable valve. After deployment, severe aortic regurgitation was revealed by aortography. Transesophageal echocardiography showed hypomobility of one of the 3 leaflets. Unsuccessful attempts to restore mobility were made using a pigtail catheter and performing postdilation, requiring a valve-in-valve procedure, without any hemodynamic compromise. DISCUSSION: Anatomical and procedural factors may be responsible for frozen leaflet during TAVI, predominantly reported with balloon-expandable valves. Transesophageal echocardiography enables rapid recognition, while angiography alone may be insufficient. A prompt hemodynamic support could be also required to avoid adverse procedural outcomes.
conclusionsA structured intervention algorithm and timely multidisciplinary involvement is essential to optimize outcomes in this high-risk situation.
