Episode Details

CardioNerds meet with fellows from The Christ Hospital, Drs. Hanad Bashir, Hyunsoo Chung, and Dalia Aziz to discuss the following case that highlights angioleiomyoma:

A 60-year-old woman with a past medical history significant for breast cancer (on tamoxifen) presented as a transfer to our facility for a clot-in-transit. She had initially presented to the outside hospital after progressive dyspnea on exertion and recent syncope. She was found on an echocardiogram to have a right atrial mass spanning into the right ventricle. CTA of the chest and abdomen/pelvis demonstrated extensive thrombus burden spanning from the IVC into the right ventricle. She was transferred to our facility for intervention.

Endovascular attempts were unsuccessful, at which point she underwent surgical thrombectomy. Gross examination of the mass revealed a cylindrical shape, homogeneous tan color, rubbery soft tissue, measuring 25.5 cm in length and 2.3 cm in diameter. Histology confirmed the presence of angioleiomyoma. A second, smaller mass (5.2cm long and 4mm in diameter) was removed from under the tricuspid valve, with histology consistent with leiomyoma. Estrogen receptor and progesterone receptor staining were strongly positive, leading to the discontinuation of tamoxifen. Given the presence of uterine fibroids identified on the CT scan, there was concern about a uterine origin. A hysterectomy is planned for her in the near future.

Expert commentary is provided by Dr. Wojciech Mazur. Episode audio was edited by student Dr. Adriana Mares.
