Randomized Controlled TrialEndoscopic left sympathetic blockade in the treatment for dilated cardiomyopathy.
The level of sympathetic nervous activity is a major determinant of prognosis in patients with heart failure. ⋯ Endoscopic left thoracic sympathetic blockade is feasible and appears to be safe in severe heart failure patients. This initial study suggests that this procedure might be an effective alternative approach to sympathetic blockade in the treatment of dilated cardiomyopathies.
