Electrocardiography, chest x-ray, and routine laboratory tests were unremarkable. Transthoracic echocardiography revealed a large left atrial mass involving the right pulmonary vein and causing stenosis. Multimodality imaging, including cardiac computed tomography (CT), cardiac magnetic resonance imaging, and\n                      <jats:sup>1<\/jats:sup>\n                      \u2078F-FDG PET\/CT, suggested primary cardiac angiosarcoma. Considering the patient's advanced age and poor surgical candidacy, we selected a palliative transcatheter intervention. Under ICE guidance, transseptal puncture was performed. Pulmonary venography revealed severe stenosis of the right inferior pulmonary vein. After sequential balloon angioplasty, a 14\u2009\u00d7\u200940\u2005mm self-expanding stent was successfully implanted with adjunctive balloon dilation. Final angiography demonstrated complete restoration of pulmonary venous flow without residual stenosis or procedural complications. The patient's dyspnea improved markedly, and she was discharged 2 days after the procedure.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n
