Figure 1 (A) Specificity in serial versus side-by-side reads (n = 219). There is significantly greater specificity for mitral regurgitation (MR) and tricuspid regurgitation (TR) using side-by-side reading method. (B) Data loss with serial versus side-by-side reads (n = 219). Data loss is defined as valves, which were classified as nonevaluable or noncomparable. There is significantly less data loss in side-by-side reads versus serial reads for aortic regurgitation (AR), TR and nearly significant for MR.
