Stepwise Escalation of Reperfusion Therapy in Massive Pulmonary Embolism With Right Ventricular Failure.
Article in JACC. Case reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundHigh-risk (massive) pulmonary embolism (PE) is associated with early mortality due to right ventricular (RV) failure and obstructive shock. Current guidelines recommend anticoagulation and systemic thrombolysis for hemodynamically unstable PE, with escalation when thrombolysis is contraindicated or ineffective at restoring perfusion. CASE SUMMARY: A 54-year-old man with past prior deep venous thrombosis presented abroad with sudden-onset dyspnea, hypotension, and severe hypoxemia requiring emergent intubation. Computed tomography pulmonary angiography showed extensive bilateral pulmonary emboli with severe RV dysfunction. The patient received systemic alteplase followed by catheter directed thrombolysis, but persistent thrombotic burden and RV dysfunction prompted international transfer for further management. Repeat imaging revealed a residual massive saddle PE, and emergent large-bore mechanical thrombectomy restored hemodynamic stability. Recovery was complicated by encephalopathy, autonomic instability, and critical illness myopathy requiring tracheostomy and inpatient rehabilitation. DISCUSSION: This case highlights that incomplete response to thrombolysis in massive PE may warrant escalation to advanced reperfusion strategies. Postreperfusion, neurologic and functional complications can be major barriers to recovery despite achieving hemodynamic stability. TAKE-HOME MESSAGE: Persistent RV dysfunction or clot burden despite thrombolysis should prompt consideration of advanced reperfusion strategies and proactive intensive care unit recovery planning.
