Successful Mechanical Aspiration of Malignant Right Atrial Myoepithelial Tumor in Setting of Recurrent Lung Cancer.

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
backgroundMinimally invasive endovascular procedures are increasingly used for management of intracardiac masses. Here, we present a case of successful transcatheter aspiration of a malignant right atrial (RA) mass. CASE SUMMARY: A 59-year-old woman with recurrent small cell lung cancer status-post chemotherapy/radiation presented for evaluation of progressively worsening left upper extremity pain and was found to have an irregular echogenic 37 mm × 26 mm mass partially attached to the posterior atrial aspect leaflet of the tricuspid valve. The mass was successfully removed and biopsied, demonstrating malignant myoepithelial disease. DISCUSSION: Treatment strategies generally depend on symptoms and comorbidities. Currently, most intracardiac masses undergo surgical resection; however, literature has demonstrated both mechanical aspiration thrombectomy and surgical resection to have favorable outcomes. TAKE-HOME MESSAGES: No evidence-based guidelines exist for optimal management of malignant RA tumors. In our patient, mechanical aspiration thrombectomy was safe and effective for removal of the intracardiac mass.
