Sixty-eight @entity1 (mean age 49 years) were studied with contrast echocardiography (CE) and Doppler echocardiography (DE) to evaluate both methods for detecting and grading @entity997 ( @entity997 ). In all @entity1 , right ventricular (RV) angiography was performed. The severity of @entity997 was graded on a 4-point scale. Only 68 of 88 @entity1 who underwent RV angiography (77%) could be evaluated, but 65 of 68 @entity1 who underwent CE (96%) and all 68 who underwent DE (100%) could be evaluated. @entity997 was present in 33 @entity1 as seen on RV angiography. CE and DE correctly diagnosed 27 and 30 @entity1 , respectively, corresponding to a sensitivity of 82% for CE and 91% for DE. Specificity was 100% for CE and 86% for DE. CE and DE grading, respectively, of @entity997 vs RV angiographic grading showed no difference in 50 and 47 @entity1 , a 1-level difference in 8 and 13 and a 2-level difference in 7 and 5 cases. (CE-RV angiography, r = 0.84, p less than 0.001; DE-RV angiography, r = 0.82, p less than 0.001). Thus, CE and DE are accurate methods for routine diagnosis of @entity997 , with DE having higher sensitivity and easier grading. Considering the possibility of false-positive findings of our standard RV angiography, sensitivity and specificity of CE and DE could be even higher.
