Minimally Invasive Mitral Valve Surgery Compared to Sternotomy in Patients Over 70 Years Old: A Retrospective Nationwide Multicentre Study in The Netherlands.
Observational study in Interdisciplinary cardiovascular and thoracic surgery, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
objectivesOlder patients are more prone to postoperative morbidity and mortality after mitral valve (MV) surgery. Minimally invasive MV surgery (MIMVS) is increasingly adopted worldwide, with a potential benefit in the elderly. This study compares short-term and mid-term outcomes in patients above 70 years, undergoing MIMVS versus median sternotomy (MST), in a nationwide registry.
methodsAll patients above 70 years undergoing primary elective MV surgery (±tricuspid valve [TV] surgery, atrial septal defect closure, rhythm surgery) between 2013 and 2021 were included. All data were extracted from the Netherlands Heart Registration. Primary outcomes were short-term morbidity, mortality, and 5-year survival.
resultsIn total, 1418 patients were included (MST n = 797, MIMVS n = 621). No statistically significant differences in baseline characteristics were found. Median Logistic EuroSCORE I was 6.3 [4.7-8.5] vs 6.0 [4.6-8.5], P = .27 for MST and MIMVS, respectively. Mitral valve repair (77.7% vs 64.7% P < .001) and concomitant TV surgery (43.9% vs 18.2%, P < .001) was more frequently performed in MST. Lower 30-day mortality was observed in MIMVS (0.6% [n = 4] vs 2.5% [n = 21], P = .01). Furthermore, the incidence of pneumonia, prolonged intubation, readmission to intensive care unit, kidney failure, and new-onset arrhythmia were lower for MIMVS. No difference in 5-year survival was found (MST: 89.1 ± 4.6% vs MIMVS: 91.6 ± 4.7% Log-Rank P = .51).
conclusionsMinimally invasive MV surgery in patients above 70 years may be associated with lower 30-day mortality and incidence of postoperative complications compared with sternotomy.
