Biventricular takotsubo cardiomyopathy with asymmetrical wall motion abnormality between left and right ventricle: a report of new case and literature review.
Review in Journal of echocardiography, 2019. 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
Takotsubo cardiomyopathy (TC) is characterized by transient wall motion abnormalities most commonly involving the left ventricle (LV). Although biventricular TC had been considered uncommon condition, recently biventricular TC has been reported as a new variant observed in 19-42% of all TC presentations. Since biventricular TC has a poor prognosis as compared with isolated TC, it is important to distinguish between isolated LV TC and biventricular TC. We present a case of 70-year-old female with dyspnea persisting for 2 days. Electrocardiogram showed symmetrical T-wave inversion in leads V2-V4. Transthoracic echocardiography (TTE) revealed diffuse hypo-kinesis except for the apical inferior LV and LV ejection fraction of 32%. Hyper-kinesis of the right ventricular (RV) basal segment and dys-kinesis of the RV apical segment. 2 weeks after admission, coronary angiography showed no evidence of significant stenosis. LV ejection fraction improved to 51% and wall motion abnormalities of the RV basal and apical segments were ameliorated to normo-kinesis. Electrocardiogram revealed symmetrical and deepened T-wave inversion in leads V2-V3. The presence of a transient abnormality in biventricular wall motion beyond a single coronary artery perfusion territory with new electrocardiographic change met the diagnostic criteria of definite TC defined by Mayo Clinic criteria. 4 weeks after admission, no recurrence of wall motion abnormalities in both ventricles were found and T-wave inversion ameliorated. To our knowledge, this is the first report of biventricular TC with asymmetrical abnormities of wall motion between LV and RV.
