Orthotopic Heart Transplantation in a Patient With Gitelman Syndrome and Dilated Cardiomyopathy.

Gitelman syndrome (GS) is a rare hereditary tubulopathy affecting the distal tubule leading to significant electrolyte disturbances. Although generally a benign condition, rare associations with arrhythmias and sudden cardiac death have been reported. A paucity of literature exists associating GS with cardiomyopathy. We present a child with dilated cardiomyopathy and GS who was successfully treated with orthotopic heart transplantation.
