Minimally Invasive Mitral Valve Surgery: Long-Term (20-Year) Follow-Up After Right Anterolateral Minithoracotomy.
Article in CJC open, 2025. 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
Background: Minimally invasive mitral valve (MV) surgery (MIMVS) through right lateral minithoracotomy has evolved as the standard approach for most patients. Data on long-term functional outcomes, however, are rare. We evaluated long-term outcomes after MIMVS through right minithoracotomy for up to 21.6 years. Methods: From 1997 to 2017, 301 patients with a median age of 57 years (range, 20-81; 54.5% female) underwent MIMVS through right anterolateral minithoracotomy. Follow-up data were evaluated using Kaplan-Meier analyses and competing risk analysis. Results: A total of 249 patients (82.7%) underwent MV repair, and 52 (17.2%) received valve replacement. Conversion to sternotomy was required in 2 patients (0.8%), and 2 patients (0.8%) suffered perioperative stroke. The 30-day mortality rate was 3.3%. During follow-up, 21 patients required MV reoperation after a mean period of 21.6 ± 0.2 years. The cumulative incidence of reoperation at 5, 10, 15, and 20 years, respectively, was 2.0% ± 0.8%, 4.5% ± 1.2%, 6.0% ± 1.4%, and 7.0% ± 1.6%. The cumulative incidence of recurrent mitral regurgitation ≥ moderate at 5, 10, 15, and 20 years, respectively, was 4.5% ± 1.2%, 11.1% ± 1.9%, 16.4% ± 2.2%, and 20.2% ± 2.7%. The 10- and 20-year survival of all patients was 83.6% ± 2% and 55.0% ± 4%, respectively. Conclusions: MIMVS can be performed safely with very good perioperative outcomes, a low incidence of mortality, and excellent long-term valve performance.
