case_images: Her electrocardiogram (Figure 1) showed sinus rhythm with no further changes.
case_images: Ecocardiograma transtoracico PSAX ao nivel da valva aortica (A) e apical 4 camaras (B; ampliado), evidenciando massa arredondada na auricula direita, ecogenica, movel, de etiologia duvidosa, com cerca de 6 mm de diametro, em possivel relacao com a valvula de Eustaquio.

case_images: A transthoracic echocardiogram (Figure 2) revealed normally sized heart chambers, normal ventricular wall thickness and preserved biventricular systolic function.
case_images: Ecocardiograma transesofagico, corte medio esofagico bicaval e plano X (A) e (B), evidenciando, ao nivel da saida da veia cava inferior, volumosa massa arredondada (25x32 mm), pediculada, com limites bem definidos e aspecto capsulado (bordas ecogenicas com interior solido aparentemente hipoecogenico em relacao as paredes cardiacas).

case_images: A transesophageal echocardiogram (Figure 3) showed, at the level of the inferior vena cava, a large, rounded mass (25x32 mm), pediculated, with well-defined borders and capsulated aspect (echogenic borders with apparently hypoechogenic solid interior, compared to the cardiac walls).
case_images: Ressonancia magnetica cardiaca revelando massa movel na auricula direita, bem delimitada (A), com 28 x 15 x 25 mm (B) de tamanho, aparentemente oriunda da porcao inferior do septo interatrial. A referida massa era isointensa em T1 (C), isointensa em T2 (D), sem perfusao nas imagens de primeira passagem (E) e sem realce precoce ou tardio (F).

case_images: Cardiac magnetic resonance imaging (CMR; Figure 4) confirmed the presence of a well-delimited, mobile mass, 28x15x25 mm in size, with apparent origin in the lower portion of the right face of the interatrial septum.
case_images: Analise histopatologica do tecido removido, estabelecendo o diagnostico de angioma cardiaco: (A) Lesao angiomatosa de vasos ectasicos; o miocardio pode ser visto na periferia. (B) Vasos revestidos por celulas endoteliais sem atipias.
