Response

We thank O’Toole, Brown and Drake for their informative response to our article.¹ We agree that it is important to highlight alternative parenteral regimens to alpha-blockers. In addition, volume expansion and careful management of fluid status is central to successful management as in our case. We also thank Whitelaw, Prague and Mustafa for their insights into the use of mechanical circulatory support as rescue therapy. We acknowledge the association with myocardial dysfunction associated with catecholamine toxicity. In collaboration with colleagues in Oxford and London, we previously reported on the high prevalence of cardiac involvement in newly diagnosed phaeochromocytomas along with persistence of some parameters on cardiac magnetic resonance following successful surgery. We would advocate for the use of multi-centre registries for such rare conditions to improve treatment outcomes.
