Transvenous cryothermal catheter ablation of a right anteroseptal accessory pathway.

abstract：:Arrhythmogenic right ventricular cardiomyopathy (ARVC) is an uncommon cardiomyopathy most classically associated with mutations in genes encoding desmosomal proteins. Recent literature has identified mutations in several non-desmosomal proteins including lamins that may result in the ARVC phenotype. We describe a pati...
