ST-segment elevation in V1-4 in takotsubo cardiomyopathy with ventricular septal perforation: A case report and literature review.
Article in Heliyon, 2024. 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
Background: Takotsubo cardiomyopathy (TCM) is a nonischemic cardiomyopathy characterized by chest pain, typically manifesting transient left ventricular (LV) apical akinesis, and ischemic electrocardiographic changes, mimicking acute coronary syndrome (ACS). Although ventricular septal perforation (VSP) is a rare complication of TCM, it is potentially life-threatening if left untreated. Whether the conventional electrocardiographic criteria for TCM are beneficial, even in patients of TCM with VSP, remains unclear. Case presentation: An 87-year-old woman was admitted for worsening dyspnea. Elevated serum cardiac enzyme levels, LV dysfunction on echocardiography, and ST-segment elevation in leads V1-4 on electrocardiogram were initially suggestive of ACS. An emergency coronary angiography revealed 90 % focal stenosis of the mid-portion of the right coronary artery (RCA) with Thrombolysis in Myocardial Infarction flow grade 2. However, left ventriculography revealed LV apical ballooning with a coexisting left-to-right shunting, which was beyond single RCA distributions, leading to a final diagnosis of TCM with VSP. Repeat echocardiography confirmed VSP and right ventricular involvement with severe pulmonary hypertension. Following successful percutaneous coronary intervention with a drug-eluting stent for RCA stenosis, the patient was managed with medical treatment without surgical intervention. Eventually, VSP and associated pulmonary hypertension markedly improved along with the normalization of the patient's cardiac structure and function. The patient's clinical course was uneventful at the 1-year follow-up. Conclusions: Herein, we describe the case of TCM with VSP that we successfully managed with medical treatments. Our case highlights the significance of elucidating this rare complication of TCM, pitfalls of the conventional electrocardiographic diagnostic criteria for TCM, and potential of this unique electrocardiographic pattern for identifying TCM-associated VSP.
