Combination of rescue balloon pulmonary angioplasty and riociguat therapy for chronic thromboembolic pulmonary hypertension with nonsustained polymorphic ventricular tachycardia: A case report.
Article in Pulmonary circulation, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
We encountered a case of frequent nonsustained polymorphic ventricular tachycardia (NSPVT) due to hemodynamically unstable chronic thromboembolic pulmonary hypertension (CTEPH). A 78-year-old woman was taking anticoagulants for CTEPH. She had refused specific treatment for CTEPH, including pulmonary vasodilators, because she was then asymptomatic. She fell and sustained a femoral neck fracture, and she was referred to our hospital in anticipation of a surgical repair. Her condition on admission was complicated by respiratory failure, and electrocardiogram monitoring showed frequent NSPVT. A right heart catheterization revealed high mean pulmonary artery pressure with severely reduced cardiac output. Pulmonary angiography showed bilateral stenosis and multiple obstructions. Because NSPVT was attributed to low cardiac output syndrome caused by CTEPH, rescue balloon pulmonary angioplasty (BPA) was performed, and riociguat treatment was initiated. Afterward, the NSPVT resolved. This case suggests that the combination of rescue BPA with riociguat therapy might be an immediate and effective treatment for patients with inoperable CTEPH and severe hemodynamic instability.
