Unipolar Electrocautery Ablation via Minithoracotomy for Atrial Tachycardia Originating From the Right Atrial Appendage.

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
backgroundCatheter ablation for atrial tachycardia (AT) originating from the atrial appendage can be challenging, and it carries a risk of complications. CASE SUMMARY: A 65-year-old woman with drug-refractory AT originating from the base of a bifid right atrial appendage underwent a hybrid procedure after failed radiofrequency ablation. Via minithoracotomy, the earliest activation site was visually identified and successfully ablated under direct vision using unipolar electrocautery, resulting in immediate termination and noninducibility. The patient remained asymptomatic in sinus rhythm at the 1-month follow-up. DISCUSSION: Direct visual unipolar electrocautery via minithoracotomy is a safe and effective alternative to appendage ligation or resection for managing challenging right atrial appendage-origin AT. TAKE-HOME MESSAGES: A minimally invasive surgical approach with direct visual electrocautery is a safe and effective therapeutic alternative for challenging appendage-origin AT. This technique should be considered when percutaneous ablation is unsuccessful or high risk.
