Intraarterial sound was measured just distal to the aortic and pulmonary valves of 10 subjects with no apparent valve disease. Six patients had no audible murmur; four had grade 1 to 2 innocent murmurs. At rest, during normal sinus rhythm, the intensity of intraarterial sound was greater above the aortic than above the pulmonary valve (0.41+/-0.14 versus 0.02+/-0.01 ergs/sec per cm2 [mean+/-standard error of the mean]) (P less than 0.02). In all patients with an audible murmur, the murmur was… CONTINUE READING
