Cineaortography provides a semiquantitative preoperative assessment of aortic regurgitation which may differ considerably from the actual finding at operation. This study reports the use of the transcutaneous ultrasonic Doppler velocity probe as a more precise yet nontraumatic technique for the preoperative quantitative assessment of aortic regurgitation and is an extension to humans of our previously reported work on the use of this technique for the detection of experimentally produced reversible aortic regurgitation in dogs. In 16 subjects aortic flow velocity was monitored using a 2.25 MHz transducer directed toward the ascending aorta from the suprasternal notch. Aortic flow velocity was
