Dyssynchrony cardiomyopathy in patients with Wolff-Parkinson-White syndrome: solved and unsolved problems

The article presents a review on dilated cardiomyopathy in patients with the Wolff-Parkinson-White syndrome. It is shown that in young children with the Wolff-Par-kinson-White syndrome, the most pronounced pre-excitation on the electrocardiogram and the right septal or right lateral location of accessory atrioventricular pathways, hypotrophy and dyskinesia of the interventricular septum may occur, with subsequent left ventricular dilation and dysfunction. However, these factors are not specific and cardiomyopathy development is possible in patients of any age and with other locations of additional conduction pathways. In addition, the current classifications of cardiomyopathies in children do not include a concept that includes this condition, and there are no criteria for making this diagnosis.
