Résumé
Anomalous aortic origin of a coronary artery (AAOCA) is a potential etiology of sudden cardiac death (SCD) in physically active individuals. Identification of coronary artery origins is an essential part of comprehensive pre-participation athletic screening. Although echocardiography is an established method for identifying AAOCA, current imaging protocols are time intensive and readers frequently have low confidence in coronary artery identification. Echocardiographic images from a sample of 110 patients from a database of competitive athletes ages 13-22 years from the Kansas City metropolitan area were reviewed by six echocardiographers of varying experience. Coronary artery images were provided to the readers in the conventional single plane for all the patients; then biplane images of the same patients were presented to the readers. While reviewing the images, readers recorded perceived confidence level of identifying the coronary artery from 1 (least confident) to 5 (most confident). Ratings and differences between ratings were summarized descriptively by means and standard deviations across all readings as well as by individual reader. The mean confidence level of echocardiogram readers in identifying coronary artery origins increased by 0.4 points (P = .05) on a five-point confidence scale when using biplane imaging rather than single plane imaging. When assessing the variability of confidence of readers on the same patient, the between-reader variability improved from 25.9% to 10.3%. Biplane echocardiographic imaging increases the confidence of readers in identifying coronary artery origins.
