Anesthetic management of transapical beating-heart septal myectomy in a child with obstructive hypertrophic cardiomyopathy: a case report.
Article in BMC anesthesiology, 2026. 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
backgroundTransapical beating‑heart septal myectomy (TA‑BSM) is considered an effective surgical approach for obstructive hypertrophic cardiomyopathy (oHCM). However, data regarding its application in pediatric patients remain limited. To date, no cases have been reported detailing the anesthetic management for pediatric oHCM patients undergoing TA‑BSM. CASE PRESENTATION: We report the case of a 9‑year‑old girl with oHCM who underwent TA‑BSM under general anesthesia. Despite thorough preoperative preparation, she experienced significant perioperative complications, including hypotension and ventricular arrhythmias. Cardiac arrest occurred during rotation of the beating‑heart myectomy device (BMD) to adjust its angle. This critical event was successfully managed through direct epicardial compression, emergency temporary pacemaker implantation, and multidisciplinary collaboration, ultimately resulting in the patient's favorable recovery. Pathology confirmed obstructive hypertrophic cardiomyopathy.
conclusionPerioperative multidisciplinary collaboration and meticulous hemodynamic management are essential for the safe performance of TA‑BSM in pediatric patients with oHCM, offering guidance for similar cases.
