Point-of-Care Ultrasound in the Diagnosis of Pulmonary Embolism With Right Heart Strain: A Case Report of Dialysis Line-Related Complications.

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
Pulmonary embolism (PE) represents a significant cause of preventable death among critically ill patients, with the immediate diagnosis impaired by the presence of hemodynamic compromise and limited access to advanced imaging. Point-of-care ultrasound (POCUS) is a rapid bedside tool for diagnosing right heart strain, which can aid in immediate clinical management. Here we report a case of a 57-year-old man with end-stage renal disease who was on hemodialysis through a Hemodialysis Reliable Outflow (HeRO) graft and presented with acute hypoxia and cardiovascular collapse after recent orthopedic surgery. Bedside POCUS showed a dilated, hypokinetic right ventricle and a mobile echogenic mass adjacent to the tricuspid valve, concerning for thrombus and device-related PE. Due to the subsequent hemodynamic instability, systemic thrombolysis was performed during cardiac arrest with return of spontaneous circulation. Follow-up CT pulmonary angiogram revealed extensive bilateral PE with right heart strain, and transesophageal echocardiography (TEE) showed the HeRO graft tip abutting the tricuspid valve with no evidence of thrombus attached to the tricuspid valve. Following a multidisciplinary discussion, the HeRO graft was removed, and therapeutic anticoagulation was initiated, resulting in complete resolution. This case highlights the life-saving role of POCUS in promptly screening and guiding the emergent management of PE when standard imaging is unavailable. It also demonstrates an uncommon but potentially life-threatening HeRO graft-related complication: intracardiac thrombus formation with PE, and its features emphasize the importance of heightened clinical suspicion and a multidisciplinary approach for such patients.
