In the present study, we compared three‐dimensionally (3‐D) reconstructed images with multiplane two‐dimensional (2‐D) transesophageal echocardiographic (TEE) images in 17 patients with various cardiac masses and defects. To overcome the problem of making measurements from 3‐D reconstructed images, we carefully “dissected” the 3‐D dataset using paraplane and anyplane 2‐D sections, which were then used to obtain the maximum sizes of the cardiac masses and defects. Of the 15 vegetations and 9 abscesses detected by 3‐D TEE in 7 patients, only 8 (53%) vegetations and 4 (44%) abscesses were detected by multiplane 2‐D TEE (P < 0.02). Also, the exact anatomical location, shape, geometry, and extent of various cardiac masses and defects were more clearly delineated by 3‐D than 2‐D TEE. The maximum dimensions of cardiac masses and defects were larger by 3‐D than by 2‐D TEE in 17 (89%) of the 19 lesions available for comparison (P < 0.002). In addition, 3‐D TEE correlated more closely than 2‐D TEE when compared to surgical measurements in three patients in whom they were available. Thus, it would appear that in several instances, the exact size of the cardiac lesion could only be assessed by analysis of the 3‐D volumetric dataset. Out preliminary study has demonstrated the superiority of transesophageal 3‐D reconstruction over multiplane 2‐D TEE in both qualitative and quantitative assessment of various cardiac mass lesions and pathological defects.

The presence of EV, higher Child-Pugh class, and higher resistance index assessed by ECDUS before B-RTO were significant risk factors for worsening of EV after B-RTO.
