Catecholamine Cardiomyopathy Associated With Paraganglioma Rescued by Percutaneous Cardiopulmonary Support

Inverted Takotsubo Contractile Pattern

Abstract

A case of catecholamine cardiomyopathy associated with paraganglioma, which was rescued by percutaneous cardiopulmonary support system (PCPS), is presented. Unlike typical apical ballooning, transthoracic echocardiography and left ventriculography revealed severe left ventricular (LV) dysfunction and an abnormal contractile pattern, consisting of akinesis of the basal and midventricular segments and hyperkinesis of the apical segments. Because of the intractable cardiogenic shock, despite conventional treatment, PCPS was performed. The underlying disease was paraganglioma. Catecholamine excess may induce not only transient LV apical ballooning but also atypical LV ballooning without involvement of the LV apex. Early use of PCPS is important for the patient with a catecholamine crisis who is not stabilized by intra-aortic balloon pump as well as infusion of fluid and inotropic agents.
