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

introductionImmunoglobulin G4 (IgG4)-related constrictive pericarditis (CP) is a rare condition with no standardized treatment. Surgical pericardiectomy is challenging due to dense adhesions and the risk of injury to the phrenic nerves and heart. Conventional energy devices carry risks of thermal damage. We report a novel application of a microwave ablation device (Acrosurg; Nikkiso, Tokyo, Japan) for radical pericardiectomy, highlighting its advantages in preventing nerve injury and ensuring hemostatic control. CASE PRESENTATION: A 79-year-old male patient with recurrent heart failure due to IgG4-related CP underwent off-pump radical pericardiectomy using a microwave ablation device (Acrosurg) and a positioner. The Acrosurg device enabled extensive and precise resection up to 1.5 cm from the phrenic nerves, achieving near total pericardiectomy without thermal injury, arrhythmia, or nerve paralysis. Postoperatively, cardiac index increased and central venous pressure normalized. The patient remained recurrence-free without steroids.

conclusionsThis case demonstrated that the Acrosurg device allows safe and curative resection for CP, highlighting its utility as an innovative surgical tool.
