OBJECTIVES: This study of 3-dimensional (3D) transesophageal echocardiography (TEE) aimed to demonstrate features  associated with @entity337 (AR) after transcatheter aortic valve replacement (TAVR)  and  to confirm the fact that a gap between the native aortic annulus and prosthesis is associated with @entity337 . BACKGROUND: The mechanism of AR after TAVR, particularly that of transvalvular AR, has not been evaluated adequately. METHODS: All @entity1 with severe @entity472 who underwent TAVR with the Sapien device (Edwards Lifesciences, Irvine, California) had 3D TEE of the pre-procedural native aortic annulus and the post-procedural prosthetic valve. RESULTS: In the 201 @entity1 studied, the total AR was mild in 67 @entity1 (33%), moderate in 21 @entity1 (10%), and severe in no @entity1 . There were 20 @entity1 with transvalvular AR and 82 @entity1 with @entity337 . Fourteen @entity1 had both transvalvular and @entity337 . @entity1 with transvalvular AR had larger prosthetic expansion (p  <0.05), a more elliptical prosthetic shape at the prosthetic commissure level (p  <0.01) and more anti-anatomical position (p  <0.001), which was defined as malposition of the prosthetic commissures in relation to the native commissures, than the @entity1 without transvalvular AR. Age (odds ratio [OR]: 1.05; 95% confidence interval [CI]: 1.01 to 1.09; p  < 0.05) and effective area oversizing (OR: 0.97; 95% CI: 0.93 to 0.99, p  <0.05) were associated with mild or greater @entity337 . CONCLUSIONS: 3D TEE successfully demonstrated the features associated with transvalvular AR, such as large prosthetic expansion, elliptical prosthetic shape, and anti-anatomical position of prosthesis. Additionally, effective area oversizing was associated with @entity337 .
