Radiation exposure to patients undergoing percutaneous coronary interventions: are current reference values too high?

abstract：BACKGROUND:Takotsubo cardiomyopathy (TTC) is a transient left ventricular (LV) dysfunction that predominantly affects older women and has three main variants: apical, mid-ventricular, and basal. The recurrence rate of TTC is roughly around 11 % at 4-year follow-up. The pathogenesis of TTC is not clear and various theor...
