Journal Article 2019 08 17 <strong>CASE PRESENTATION</strong><br /> Metastatic cardiac masses have different primary sites. On rare occasions, uterine tumors are responsible for such masses. We herein describe a woman with a metastatic cardiac mass originating from a benign uterine leiomyoma. The patient had severe and chronic abnormal uterine bleeding, for which she finally referred to our hospital. On admission, she had acute respiratory distress. Echocardiography showed a huge right atrial mass that had occupied most of this atrial space. The mass originated from the inferior vena cava (IVC) and extended across the tricuspid valve to the right ventricle. The mass was successfully resected under cardiopulmonary bypass. Subsequent evaluations, including a pathologic examination, revealed a metastatic uterine leiomyoma extending to the right atrium after invasion into the IVC. <strong><em>(Iranian Heart Journal 2020; 21(3): 145-149)</em></strong> https://journal.iha.org.ir/article_110227_630614b82a3348e1d472c0471e6aa0dc.pdf
