“…First, sinus arrest can be developed on day 4 after paraganglioma resection. Several cases reported that patients with pheochromocytoma developed bradycardia, including sinus arrest during the perioperative period (2,3,4). There was also a report regarding circulatory failure during the resection of paraganglioma (5).…”

Paragangliomas are neural-crest-derived nonepithelial neuroendocrine tumors distributed along the parasympathetic and sympathetic nerves. To our knowledge, no studies were reported regarding sinus arrest on day 4 after paraganglioma resection. A 66-year-old female patient with a history of pulmonary vein isolation visited our department for sigmoid colon cancer treatment. Enhanced computed tomography revealed an enhanced small nodule-like lymph node near the root of the inferior mesenteric artery. The patient underwent laparoscopic colectomy with regional lymph node dissection. Postoperatively, paroxysmal atrial fibrillation attacks developed, and the patient resumed oral medication. Additionally, sinus arrest after tachycardia developed. Changing the oral medication could maintain her circulatory dynamics. Pathological examination revealed that differentiated tubular adenocarcinoma infiltrated the submucosa. Immunohistochemically, the excised nodule as a lymph node was considered a functional paraganglioma. Our case indicates that paraganglioma resection and oral medication resumption may contribute to sinus arrest. When arrhythmias affecting the circulation occur perioperatively, the presence of a catecholamine-producing tumor should be considered in addition to cardiac disease.

“…Although rare, pheochromocytoma can result in QT prolongation, even malignant arrhythmias such as ventricular tachycardia. 16 Several recent case reports have described cases of ventricular tachycardia accompanying a patient with suspected acute myocardial infarction but no coronary artery stenosis on angiography. The more common arrhythmias in pheochromocytoma are sinus tachycardia, atrial fibrillation, and atrial flutter.…”

Cardiovascular Presentation in Pheochromocytoma: What We Should be Aware

Pheochromocytoma is a catecholamine-producing tumor that although being a rare disease, it poses diagnostic problems because its clinical presentation often mimics certain diseases, including cardiovascular disorders. The effects of excessive catecholamine secretion cause a variety of cardiovascular presentations ranging from hypertension to life-threatening cases such as hypertensive emergency, shock, supraventricular or ventricular arrhythmias, pulmonary edema, and acute coronary syndromes. The principal medical treatment for pheochromocytoma is a blockade of adrenergic receptors. However, surgical or tumor resection often provides complete resolution of abnormal myocardial dysfunction or arrhythmias, so this approach remains the mainstay of treatment that should be performed as soon as the diagnosis of pheochromocytoma is established. As clinicians, we must be aware of the characteristics of the cardiovascular manifestations of pheochromocytoma to make an earlier diagnosis and more appropriate management.
