People with WPW may have more than one accessory pathwayâin some cases, as many as eight abnormal pathways have been found. This has been seen in individuals with Ebstein's anomaly. WolffâParkinsonâWhite syndrome is sometimes associated with Leber's hereditary optic neuropathy (LHON), a form of mitochondrial disease.
