Simultaneous transapical transcatheter aortic and mitral valve replacement in patients with severe valve dysfunction: initial experience.

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
backgroundSimultaneous transcatheter mitral valve in valve (VIV) replacement and aortic valve replacement experience is limited. We report our initial experience with simultaneous transapical transcatheter aortic and mitral valve replacement in patients with severe valve dysfunction.
methodsA total of 8 patients had simultaneous transcatheter heart valve implants for severe mitral bioprosthesis failure (VIV), with a second valve procedure that included native aortic regurgitation (n = 3) or degenerated bioprostheses in the aortic position (n = 5). All patients were treated with a self-expandable J-valve transcatheter valve, using the transapical approach.
resultsThe mean age of the patients was 73.1 ± 6.2 years. The mean Society of Thoracic Surgeons score was 13.8 ± 6.3%. Device success was 100% according to Valve Academic Research Consortium-2 criteria. No other procedure-associated complications occurred, including left ventricular outflow tract obstruction and valve migration. The mean hospital lengths of stay after the procedure were 11.5 ± 8.0 days. No deaths occurred at 30 days. At a median follow-up period of 28.7 ± 22.3 months, no patients died. All patients were in New York Heart Association functional classes I-II. Echocardiographic parameters at follow-up showed a normofunctioning J valve in the mitral position and a mean max mitral flow velocity of 2.0 ± 0.5 m/s; the J valve in the aortic position was also normofunctioning, and the mean max aortic flow velocity was 2.3 ± 0.5 m/s.
conclusionSimultaneous transapical transcatheter aortic and mitral valve replacement using the self-expandable J valve appears to be a feasible and effective alternative to redo surgery.
