Key result
Resynchronization therapy led to normalization of left ventricular function in patients with long-standing LBBB, suggesting it as a reversible cause of cardiomyopathy.

May support CRT for LV recovery in select non-ischemic cardiomyopathy with LBBB; leaves open whether long-standing LBBB is a reversible cause.
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.
