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

objectivesData related to valvular heart surgeries from the Japan Cardiovascular Surgery Database in 2015 and 2016 were analyzed to demonstrate the associated mortality and morbidity rates and choice of surgical procedures.

methodsWe used the Japan Cardiovascular Surgery Database to extract data related to cardiac valve replacement procedures performed in 2015 and 2016. The cases were further evaluated depending upon the type of procedure and prosthesis used at each site. The percentage of bio-prosthesis usage was calculated for each valve position and age group. The rates of operative mortality and morbidity were calculated for each valve position and type of procedure.

resultsOverall, 26,054 aortic valve replacements were performed in 2015 and 2016, showing a slightly larger number than the last report (2013-2014). A total of 3305 transcatheter aortic valve replacements, 5652 mitral valve replacements and 12,024 mitral valve repair procedures were performed. The percentage of bio-prosthesis usage in aortic valve replacement was 96.5, 92.7, and 63.5% for patients in their 80s, 70s, and 60s, respectively, demonstrating an increase in usage since 2013-2014. Mechanical valves were preferred in patients on chronic hemodialysis. The mortality rates of aortic valve replacement, mitral valve replacement, mitral valve repair, and tricuspid valve replacement procedures were 4.1, 7.1, 2.2, and 10.5%, respectively.

conclusionWe evaluated recent trends in valvular heart surgery in Japan with respect to the type of procedure and prosthesis preferred and the postoperative outcomes. We found that bio-prosthesis usage was becoming more common.
