Bidirectional ventricular tachycardia and cardiogenic shock caused by acute haemorrhagic necrosis of pheochromocytoma: a case report.

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
Background: Pheochromocytoma is associated with serious cardiovascular complications resulting from the effect of catecholamines, such as ventricular arrhythmias, cardiomyopathy with left ventricular dysfunction, and cardiogenic shock. Bidirectional ventricular tachycardia (BVT) is a rare but potentially fatal form of polymorphic tachycardia associated with elevated sympathetic tone. Case summary: A 27-year-old Caucasian woman was admitted to the intensive care unit with cardiogenic shock. The electrocardiogram showed BVT, and the transthoracic echocardiogram showed a dilated left ventricle with severe systolic dysfunction. Computed tomography revealed an adrenal mass with haemorrhage, which was confirmed by abdominal magnetic resonance imaging. The patient underwent a laparoscopic right adrenalectomy after pre-operative preparation with alpha-beta blockade, with subsequent histopathological confirmation of the diagnosis. Discussion: The acute presentation of haemorrhagic necrosis of a pheochromocytoma is a rare and potentially lethal condition. Its diagnosis can be challenging, especially in cases with atypical manifestations. However, the presence of BVT might serve as a crucial guide for its identification. Early recognition of this condition is essential, as it significantly impacts the patient's prognosis.
