Abstract

A female baby suffered from a rare association between histiocytoid cardiomyopathy, left ventricular non-compaction, and Wolff–Parkinson–White syndrome causing severe and recurrent arrhythmic storms. Antiarrhythmic drugs, radiofrequency ablation of Purkinje tissue, and sympathetic denervation were ineffective. The implant of a cardiac defibrillator allowed her to survive till heart transplant. Compound mutation of CACNA2D1 and RANGRF genes were found. To the best of our knowledge, this is the first comprehensive description of the concurrence of these two mutations and histiocytoid cardiomyopathy.
