case_images: Magnetic resonance imaging (MRI) of a cardiac tumor in the right atrium and ventricle. (A) Coronal reconstruction of a T1-weighted sequence showing the distribution of the mass within the right atrium (arrows). (B) Coronal plane of a T1-weighted sequence highlighting the tumor's extension into the right ventricle. (C) Transverse plane of a T1-weighted sequence depicting the mass within the right ventricle. (D) Transverse cross-sectional plane of a T2-weighted sequence demonstrating the mass's extension and spatial orientation.

case_images: However, a large mass was observed infiltrating the right ventricle wall, involving the tricuspid valve annulus, and extending into the right atrium (Figure 1).
case_images: Intraoperative identification of the tumor in the right heart chambers (arrows). (A) Localization of the tumor in the right atrium and right ventricle (arrows), revealing a large, irregular mass extending from the right atrial wall and infiltrating adjacent right ventricular structures. (B) Tumor margins marked with blue dye (arrows) to delineate its extent. (C) Cardiopulmonary bypass is utilized to maintain systemic circulation during tumor resection. (D) The surgical field showing the exposed right heart chambers, highlighting the tumor's extensive involvement and its impact on surrounding cardiac structures.

case_images: Intraoperatively, a large, irregularly shaped mass infiltrating the right atrium and ventricle, as well as the tricuspid valve annulus, was identified (Figure 2).
case_images: Surgical debulking and partial removal of the tumor from the right heart chambers. (A) Initial incision exposing the tumor mass infiltrating the roof of the right atrium (arrow). (B) Visualization of the extensive infiltration of the right atrial wall, characterized by irregular margins (arrow). (C) Deeper extension of the tumor within the right atrium (arrow), with careful dissection performed to separate the mass from surrounding cardiac structures while minimizing damage to the heart tissue. (D) Tumor expansion involving the tricuspid valve (arrow). Additional tumor tissue is meticulously separated from the tricuspid valve region under cardiopulmonary bypass to reduce the risk of valve obstruction. The final stages of debulking show visible portions of the tumor successfully removed, improving clearance around the tricuspid valve and right atrial structures.
