    <p>A 70-year-old female patient with Ebstein's anomaly (EA) that had never undergone palliation was assessed (the case originates from the MAGYAR-Path Study). Complete two-dimensional (2D) Doppler and three-dimensional (3D) speckle-tracking echocardiography were carried out with commercially available Toshiba Artida<sup>&#8482;</sup> echocardiography equipment. During 2D echocardiography, the septal leaflet-tricuspid annulus distance showed to be 25 mm, confirming EA. While the right ventricle (RV) was enlarged with tricuspid annular plane systolic excursion &gt; 23 mm and mitral regurgitation grade III, left ventricular (LV) size and function showed to be normal with an ejection fraction of 56% without wall motion abnormalities. However, all LV regions moved in almost the same counterclockwise direction, confirming absence of LV twist, called "rigid body rotation" (RBR) (<xref ref-type="fig" rid="f1">Figure 1</xref>). The mean global LV radial, circumferential, longitudinal, 3D and area strain parameters showed to be 11.5 &#177; 10.0%, -25.5 &#177; 15.4%, -18.6 &#177; 10.2%, 15.2 &#177; 10.8% and -34.7 &#177; 20.8%, respectively. EA is a congenital heart defect in which septal and posterior leaflets of the tricuspid valve are displaced towards the RV apex, leading to RV partial atrialization, although the anatomic annulus of the valve is in the normal position.<xref ref-type="bibr" rid="B1">1</xref> Malformation and displacement of the anterior leaflet can also be present. To the best of our knowledge, this is the first report to demonstrate LV-RBR, a known feature in LV myocardial mechanics, in a single patient with unrepaired EA. LV-RBR could be partially explained by the impaired ventricle-to-ventricle interactions due to displaced tricuspid valve leaflet attachments, alterations in the anatomic myocardial fiber orientation, but other reasons could also not be excluded.</p>

The 3D image of the LV and calculated LV volumetric and functional characteristics (EDV: end-diastolic volume; ESV: end-systolic volume; EF: ejection fraction) are also demonstrated together with LV apical (white arrow), mid-ventricular and basal (dashed arrow) rotations in the same counterclockwise direction, confirming absence of the LV twist, called &#8220;rigid body rotation&#8221;.</title>

      <p>Paciente do sexo feminino de 70 anos de idade, com anomalia de Ebstein (AE), sem nunca ter sido submetida a tratamento paliativo foi avaliada (o caso tem origem no Estudo MAGYAR-Path). Foram realizados Doppler completo bidimensional (2D) e ecocardiografia tridimensional (3D) <italic>"speckle-tracking"</italic> com um equipamento de ecocardiografia Toshiba Artida, dispon&#237;vel comercialmente. Durante a ecocardiografia 2D, a dist&#226;ncia encontrada do anel tric&#250;spide e folheto septal foi de 25 mm, confirmando a AE. Enquanto o ventr&#237;culo direito (VD) estava aumentado com excurs&#227;o sist&#243;lica do plano anular tric&#250;spide &gt; 23 mm, e regurgita&#231;&#227;o mitral de grau III, o tamanho e fun&#231;&#227;o do VE mostraram-se normais, com fra&#231;&#227;o de eje&#231;&#227;o de 56%, sem anormalidades no movimento da parede. No entanto, todas as regi&#245;es do ventr&#237;culo esquerdo (VE) moveram-se praticamente no mesmo sentido anti-hor&#225;rio, confirmando a aus&#234;ncia de tor&#231;&#227;o do VE, chamada "rota&#231;&#227;o do corpo r&#237;gido" (RCG) (<xref ref-type="fig" rid="f2">Figura 1</xref>). Os par&#226;metros m&#233;dios globais radiais, circunferenciais e longitudinais do VE, 3D e da &#225;rea de deforma&#231;&#227;o <italic>(strain)</italic> do VE, foram, respectivamente, 11,5 &#177; 10,0%, -25,5 &#177; 15,4%, -18,6 &#177; 10,2%, 15,2 &#177; 10,8% e -34,7 &#177; 20,8%. A AE &#233; uma cardiopatia cong&#234;nita na qual os folhetos septal e posterior da valva tric&#250;spide s&#227;o deslocados em dire&#231;&#227;o ao &#225;pice do VD, levando &#224; atrializa&#231;&#227;o parcial do VD, apesar do anel anat&#243;mico da v&#225;lvula estar na posi&#231;&#227;o normal.<xref ref-type="bibr" rid="B1">1</xref> A malforma&#231;&#227;o e o deslocamento do folheto anterior tamb&#233;m podem estar presentes. Que seja de conhecimento dos autores, este &#233; o primeiro relato que demonstra a RCG do VE, uma caracter&#237;stica conhecida da mec&#226;nica do mioc&#225;rdio do VE, em um &#250;nico paciente com AE n&#227;o reparada. A RCG do VE poderia ser parcialmente explicada pelas intera&#231;&#245;es deficientes ventr&#237;culo-a-ventr&#237;culo devido ao deslocamento dos anexos dos folhetos da v&#225;lvula tric&#250;spide, altera&#231;&#245;es anat&#243;micas na orienta&#231;&#227;o das fibras do mioc&#225;rdio, embora outras raz&#245;es n&#227;o possam ser exclu&#237;das.</p>
