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

purposeUp-to-date national data on minimally invasive cardiac surgery (MICS) are essential for quality control but remain limited. This report summarizes 2022 outcomes of right- or left-minithoracotomy, thoracoscopic/port-assisted, and robotic-assisted MICS in Japan, based on the Japan Cardiovascular Surgery Database (JCVSD).

methodsData were collected from patients undergoing mitral valve repair/replacement (MV repair, n = 2525; MVR, n = 279), aortic valve replacement (AVR, n = 1114), coronary artery bypass grafting (CABG, n = 450), atrial septal defect closure (ASD, n = 212), and cardiac tumor resection (n = 113) using MICS approaches. Perioperative data included 30-day and in-hospital mortality, conversion rates, and major morbidities.

resultsFor MV repair, the 30-day and in-hospital mortality rates were 0.3% and 0.2% in isolated cases (n = 1461) and 0.4% and 0.6% overall, respectively. Mortality rates for MVR were 2.5% and 4.2% in isolated cases (n = 120) and 2.9% and 4.3% overall, respectively. Mortality rates for AVR were 0.6% and 1.0% in isolated cases (n = 981) and 0.9% and 1.3% overall, respectively. Mortality rates for CABG were 1.6% and 1.8%, respectively. Mortality rates were 0% for both ASD closure and tumor resection. Across the groups, conversion to full sternotomy ranged from 0% to 1.8%.

conclusionThe 2022 nationwide MICS data demonstrate consistently low mortality and morbidity across all procedure types. As MICS adoption grows, these updated JCVSD findings will serve as vital benchmarks for ongoing quality improvement in Japan.
