1 · What the graph read from it

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.

2 · The registry

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

backgroundPrior to the approval of the Sapien valve in 2020, there were no commercially available short-frame valves for transapical mitral valve-in-valve (MVIV) implantation. In January 2019, we first attempted the reverse mounted J-valve for transapical MVIV implantation with good clinical results. The present study aimed to explore the safety and effectiveness of transapical MVIV implantation with the J-valve reversely mounted on the delivery system.

methodsPatients who underwent transapical MVIV implantation using the J-valve were analyzed from January 2019 to December 2020 with a 1-year follow-up. Before the procedure, computed tomography (CT) angiography data were analyzed to determine the inner diameter, left ventricular outflow tract (LVOT), and coaxial angel. An oversize rate of 5-10% was used to select the J-valve depending on the scanned inner diameter of the original mitral bioprosthesis. During the procedure, the three U-shape graspers were one-to-one buckled with the three tissue valve struts with the assist of echo and fluoroscopy. The implant depth into the left atrium was a 0-20% part of the J-valve, and the valve was then released under rapid pacing. Post-balloon dilatation was used when needed.

resultsNineteen patients (mean age 70.05±11.19 years), with a mean Society of Thoracic Surgeons score of 8.01%±4.20%, were included. By transesophageal echocardiography, we found that the mean transvalvular gradient was 6.21±2.63 mmHg. The mean follow-up time was 20.31±7.23 months, and the survival rate was 94.74% at the last follow-up. The transvalvular gradient decreased from 15.06±3.00 mmHg at basal to 7.13±2.28 mmHg at the 1-year follow-up (P<0.001). The left ventricular ejection fractions (LVEF) increased from 60.31%±7.30% to 59.94%±7.72% at the 1-year follow-up (P=0.863). Thirteen (81.25%) patients had no or trace paravalvular leak (PVL), two (12.50%) patients had minor PVL, one (6.25%) patient had moderate PVL, and there were no cases of major regurgitation at the 1-year transthoracic echocardiography (TTE) examination results.

conclusionsThe J-valve reversely mounted on the delivery system can be used for transapical MVIV implantation with less operative morbidity and favourable outcomes.
