Near-Fatal Hemodynamic Collapse during Recovery from Staged Bladder Tumor Resection in a Patient with Giant Left Atrial Myxoma: A Case for Immediate Sequential Surgery.

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
introductionSurgical management of a large, obstructive left atrial (LA) myxoma coexisting with an active bleeding source presents a significant clinical dilemma. The systemic heparinization required for cardiopulmonary bypass (CPB) carries a high risk of exacerbating hemorrhage, whereas delaying cardiac surgery leaves the patient vulnerable to fatal myxoma-related complications. CASE PRESENTATION: A 77-year-old woman presented with gross hematuria from an 8-cm bladder tumor. Preoperative evaluation revealed a giant (74 × 40 mm) LA myxoma prolapsing through the mitral valve, causing functional mitral stenosis. A multidisciplinary team elected for a "urology-first" staged approach. Transurethral resection of the bladder tumor (TURBT) was performed under general anesthesia with successful hemostasis. However, 30 min after extubation, the patient developed acute respiratory failure and cardiogenic shock due to myxoma incarceration. She was stabilized with noninvasive positive pressure ventilation and fluid management before being transferred to the ICU. Emergency myxoma resection was performed 18 h later. No significant bladder bleeding occurred despite full heparinization.
conclusionsThis case demonstrates that the post-anesthesia recovery period is a window of extreme vulnerability for patients with obstructive myxomas, likely due to emergence-related tachycardia. The "urology-first" staged approach, while logical for bleeding control, failed to prevent a life-threatening cardiac event. Accumulating evidence suggests that bleeding risk following adequate hemostasis at TURBT is low, even under anticoagulation. For patients with high-risk cardiac lesions, an immediate sequential surgical strategy-proceeding directly to cardiac surgery under the same anesthesia once non-cardiac hemostasis is achieved-should be strongly considered to minimize the duration of risk.
