Transcatheter arterial embolization of coronary feeder vessels successfully managed surgical bleeding risks prior to open resection of a synchronous primary cardiac paraganglioma and lung adenocarcinoma.
Case Report (n=1)
Transcatheter arterial embolization of coronary feeder vessels can be successfully used to reduce tumor vascularity and bleeding risks before surgical resection of primary cardiac paragangliomas.
Abstract Background A 71-year-old female with hypercholesterolemia and pre-diabetes was referred for chest pain evaluation. Initial imaging suggested significant coronary artery disease but incidental lung and mediastinal masses raised concerns about malignancy. Case Summary Further evaluation by PET, MRI and biopsy led to the diagnosis of a synchronous primary cardiac paraganglioma and lung adenocarcinoma. There was significant vascular supply to the mediastinal mass from both coronary systems with moderate coronary artery disease. To manage surgical bleeding risks, the patient underwent transcatheter arterial embolization of the coronary feeder vessels followed by successful open resection of both mediastinal and pulmonary masses. Discussion Primary cardiac tumors are rare. Primary cardiac paragangliomas are usually benign but can be difficult to manage. A multi-disciplinary approach is vital for successful treatment with PET, CT, and MRI imaging aiding the process. Transcatheter arterial embolization (TAE) reduces tumor vascularity before surgery and potentially bleeding related complications.
Hii et al. (Tue,) conducted a case report in Primary cardiac paraganglioma and lung adenocarcinoma (n=1). Transcatheter arterial embolization of coronary feeder vessels was evaluated. Transcatheter arterial embolization of coronary feeder vessels successfully managed surgical bleeding risks prior to open resection of a synchronous primary cardiac paraganglioma and lung adenocarcinoma.
