title: The postvalvulotomy propranolol test to determine reversibility of the residual gradient in pulmonary stenosis.
abstract: We advocate the use of propranolol in very low dosage at the end of operation to determine a prognosis of the long-term results to be expected after valvulotomy in diverse types of pulmonary stenosis.
