Pheochromocytoma mimicking (or triggering?) takotsubo cardiomyopathy and Hypertrophic cardiomyopathy
To the Editor,
The 2 reasons that prompted me to provide this commentary on the interesting report by Gravina et al., published ahead of print on November 1, 2016 in the Journal [1], about a patient who suffered
complications, including left ventricular (LV) hypertrophy” [1]; however the authors’ patient was not found to be hypertensive, and the noted hypertrophy probably represented LV “pseudohypertrophy”, a reversible condition found in TTS, diagnosed by cMRI, and often misdiagnosed in the literature as LV hypertrophy due to hypertophic cardiomyopathy, or LV hypertrophy due to hy- pertension in general, or specifically PHEO-induced hypertension [8-10]; also the authors did not mention whether myocardial edema was detected in their patient by the cMRI; it would be of in- terest to document the regression of the LV apparent “hypertrophy” in their patient, by a repeat cMRI study.
