The Konno-Rastan Procedure in the Current Era: Still A Feasible Option?
Article in Brazilian journal of cardiovascular surgery, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
introductionThe Konno-Rastan procedure is a commonly used surgical technique to address complicated subaortic stenosis and to enlarge the aorta via an anterior route. The objective of this report is to describe the experience of our unit with this procedure.
methodsBetween 2002 and 2022, we identified pediatric patients who underwent the Konno-Rastan procedure. Relevant information was retrospectively collected.
resultsThere were 16 patients who underwent the Konno-Rastan procedure. The median follow-up was nine years (4 - 16 years), and there was no operative mortality. All patients had a straightforward recovery, and five patients required reoperation at follow-up, none of which was related to the left ventricular outflow tract. The median echocardiographic indices at the most recent follow-up were not significantly different from the preoperative values, with a median peak gradient across the left ventricular outflow tract of 25 mmHg. In their most recent follow-up, 81% of the patients were New York Heart Association class 1. No bleeding, thromboembolic, or infective complications were encountered.
conclusionWe concluded that the Konno-Rastan procedure can be regarded as a definitive alternative to other surgical interventions for left ventricular outflow tract obstructions. Although reoperations are still necessary, particularly in patients with additional mitral valve disease, the Konno-Rastan procedure is still a viable option in patients with complex left ventricular disease.
