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

Background: We report endocardial radiofrequency (RF) ablation as an alternative treatment approach for a symptomatic patient with obstructive hypertrophic cardiomyopathy (oHCM), who is not suitable for surgical septal myectomy or alcohol septal ablation. Endocardial RF ablation, with detailed 3D mapping of the intrinsic conducting system, offers the possibility of reducing the risk of complete heart block rates and of effectively relieving symptoms. Case summary: We present a symptomatic 51-year-old female patient with oHCM and a maximum left ventricular outflow tract (LVOT) gradient of 148 mmHg. Because of alcohol septal ablation failure, endocardial RF ablation in combination with detailed mapping of the intrinsic conduction system and intraprocedural imaging was performed. The 6-month follow-up showed a significant improvement in exercise tolerance, no relevant dynamic LVOT obstruction with a gradient of 22 mmHg under Valsalva. Discussion: In the current case report, endocardial RF ablation persistently reduced LVOT gradients in a patient with oHCM. Pre-interventional imaging, detailed 3D mapping of the conduction system, and correlation to intracardiac and transthoracic echocardiography were key for an effective and safe ablation of a small target zone.
