Does upgrading to biventricular pacing systems resolve dilated cardiomyopathy and congestive heart failure in young patients following right ventricular pacing for AV block?
Upgrading to biventricular pacing systems should be considered early to resolve pacing-induced cardiomyopathy in young patients, potentially avoiding the need for cardiac transplantation.
CRT can benefit young patients that develop CHF and DCM following RV pacing for AV block. Upgrading to biventricular pacing systems should be considered early in the management of these patients prior to listing for cardiac transplantation.
Moak et al. (2006) studied this question.
