Background Takotsubo cardiomyopathy, described as transient regional contractile abnormalities limited to the apical and mid‐segments of the left ventricle (LV), has also been reported to involve basal and/or mid LV segments (inverted Takotsubo); fewer reports, however, have addressed right ventricular (RV) dysfunction. Aim To assess the distribution of regional abnormalities and RV involvement in Takotsubo cardiomyopathy and compare it to the literature. Methods and Results We evaluated 23 patients with both classical and inverted presentations (19 female, aged 64 ± 19 years), including 2 recurrences, totaling 25 episodes. Classical Takotsubo was observed in 15 patients, while 10 had the inverted form. LV ejection fraction (EF) was lower for classical compared to inverted presentation (30 ± 7 vs. 45 ± 4%, P
