摘　　要：Quantification of degenerative mitral reg-urgitation(MR)by two-dimensional(2D)transthoracic echocardiography(TTE)and transesophageal echocardiography(TEE)is challen-ging.Eccentric,obliquely oriented regurgitant jets limit inter-observer and intra-observer consistency.In recent years,with increasingly sophisticated three-dimensional(3D)TTE and TEE systems that enable single-beat 3D color acquisition,3D vena contracta area(VCA)has emerged as an attractive indicator of MR severity.It overcomes geometric assumptions in 2D techniques and can be acquired in a single car-diac cycle,which is a major benefit in atrial fibrilla-tion.However,most studies of 3D VCA were perfo-rmed on the Philips TEE platform.[1-3]The perform-ance of the technique on GE systems and on 3D TTE is unexplored.We report 3D VCA measurements in a case of severe degenerative MR on 3D TTE(4V-D transducer,Vivid E95,GE Vingmed Ultrasound,Horten,Norway),and 3D TEE performed on GE(6VT-D transducer,Vivid E95,GE Vingmed Ultraso-und,Horten,Norway)and Philips(X7-2t transdu-cer,EPIC 7C,Philips Medical Systems,Andover,MA,USA).
