Transesophageal color flow Doppler findings were studied in 30 patients with aortic insufficiency who had cardiac operations. Measurements were expressed as ratios of corresponding left ventricular outflow tract dimensions. Regurgitant jet proximal width ratio was significantly related to jet area ratio (r = 0.92) and correlated poorly with the degree of jet penetration into the left ventricular cavity (r = 0.32). The vectors of the regurgitant jets were variable. Nine patients had undergone aortography. Regurgitant jet proximal width and area ratios were significantly related to angiographic grade (r = 0.88 and 0.87, respectively) in these patients. We concluded that the esophagus offers a satisfactory transducer orientation for color flow Doppler assessment of aortic insufficiency.
