The clinical and morphologic features of tunnel subaortic stenosis, an unusual form of obstruction to left ventricular outflow, are described in 11 patients. Although patients with tunnel subaortic stenosis demonstrate a variety of cardiovascular malformations, the most characteristic anatomic feature is fibromuscular tubular narrowing of the outflow tract that remains relatively unchanged duri...

The incidence and severity of echocardiographic findings in 19 patients treated with propranolol and in 18 not so treated showed no significant differences. Likewise these findings were unaltered by administration of propranolol in 12 patients who were studied both while th...
