Resynchronization therapy led to normalization of left ventricular function in patients with long-standing LBBB, suggesting it as a reversible cause of cardiomyopathy.
Does resynchronization therapy improve LV function in patients with non-ischaemic dilated cardiomyopathy and long-standing LBBB?
Long-standing LBBB may be a reversible cause of cardiomyopathy, as evidenced by LV function normalization after resynchronization therapy.
Normalization of LV function 1 year after resynchronization therapy in a small but important number of patients suggests that long-standing LBBB may be a newly identified reversible cause of cardiomyopathy.
Blanc et al. (2005) studied this question. Resynchronization therapy led to normalization of left ventricular function in patients with long-standing LBBB, suggesting it as a reversible cause of cardiomyopathy.
