“…Transesophageal echocardiography provides more clear images than the conventional transthoracic approach and can be performed during surgery. 2 Computed tomography with contrast and magnetic resonance imaging are often used in the evaluation of cardiac tumors, to determine the extent to which there is intramyocardial extension and the presence of tumors in adjacent extracardiac structures. 7 In summary, we report a case of a cardiac paraganglioma in the right atrioventricular groove in patient who had dilated cardiomyopathy but no hypertension.…”

“…The presence of multiple coronary artery fistulae, which are often observed in patients with cardiac paraganglioma, was noted in our patient. 6,7) Coronary artery fistulae are usually formed because of high-flow blood vessels supplying the tumor, which commonly appear highly concentrated and dilated. 7) However, neovascularization in pheochromocytomas and paragangliomas may be caused by increased production of dopamine and vascular endothelial growth factor.…”

Cardiac Dopamine-Secreting Paraganglioma with Involved Skull Base and Retroperitoneum After a History of Pheochromocytoma Post Adrenalectomy

Cardiac paragangliomas are exceedingly rare. Herein, we describe a patient with a large dopaminesecreting cardiac paraganglioma who had a history of pheochromocytoma after right adrenalectomy. The cardiac surgery was uneventful and without blood pressure fluctuations.The measurement of plasma-free metanephrines or urinary fractionated metanephrines is used as an initial screening test for pheochromocytoma or paraganglioma detection. However, these results must be combined with those of a plasma 3-methoxytyramine test to accurately establish the rare dopaminergic phenotype of pheochromocytomas or paragangliomas, if suspected. F-FDOPA (6-[18F]-L-fluoro-L-3, 4-dihydroxyphenylalanine)based positron emission tomography (PET) and PET-computed tomography are relatively sensitive and specific; therefore, these techniques are recommended for patients with pheochromocytomas or paragangliomas before operation or during postoperative follow-up.

Functioning paraganglioma is extra-adrenal catecholamine-secreting tumours that may cause secondary hypertension. Primary intrapericardial paragangliomas are very rare and are located adjacent to the great vessels or heart, typically near the left atrium. These tumours are an exceptionally uncommon finding during the investigation of refractory hypertension. However, in recent years, intrapericardial paragangliomas have been diagnosed incidentally with increased frequency, due to the extensive use of radiologic chest imaging. The mainstay of treatment of functioning intrapericardial paraganglioma is surgical removal, which usually achieves blood pressure normalization. Due to the locations of these tumours, the surgical approach is through a median sternotomy or posterolateral thoracotomy, and manipulation-induced catecholamine release may cause paroxysmal hypertension. Typically in these patients, blood pressure fluctuates dramatically intra- and post-operatively, increasing the risk of cardiovascular complications. We review here the current modalities of perioperative fluid and hypotensive drug administration in the setting of surgery for functioning intrapericardial paraganglioma and discuss the recently proposed paradigm shift that omits preoperative preparation.
