Trends in redo mitral procedure for treating mitral bioprostheses failure: a single center's experience.
Article in Annals of translational medicine, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled 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.
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
backgroundTranscatheter mitral valve-in-valve implantation (TM-VIV) has emerged as a viable and attractive alternative to surgical mitral valve replacement (SMVR). This study aimed to review a single-center experience with redo mitral procedure for mitral bioprostheses failure over an 8-year period. In addition, it compared procedural safety and early outcomes of various approaches.
methodsBetween January 2013 and January 2021, 79 consecutive patients who underwent redo procedure for mitral bioprostheses failure in our institution were retrospectively reviewed. SMVR and transapical TM-VIV were performed in 54 and 25 patients, respectively. In the SMVR group, 12 patients underwent totally thoracoscopic redo mitral valve replacement (MVR).
resultsThe annual volume of procedures grew continuously during the study period, with the use of totally thoracoscopic redo MVR increasing from 0% in 2012 to 20% in 2019. In 2020, 84.2% of total procedures were performed via the transcatheter approach. Patients in the TM-VIV group were significantly older and had higher scores on the European System for Cardiac Operative Risk Evaluation II (EuroScore II) and the Society of Thoracic Surgeons Predicted Risk of Mortality (STS PROM) (P<0.01). The in-hospital mortality for the SMVR group and TM-VIV group was 3.7% (2 patients) and 0, respectively. Compared to the SMVR group, TM-VIV was associated with shorter ventilation time, intensive care unit stay, and postoperative in-hospital stay, and there was less need for blood transfusion. In the subgroup analysis, no significant difference was detected among most perioperative outcomes between the totally thoracoscopy approach group and the TM-VIV group.
conclusionsThere is an increasing number of patients demanding surgical treatments for mitral bioprostheses failure. TM-VIV is playing a significant role due to its scope of application and excellent outcomes.
