Abstract

Objectives: This report describes a series of patients with neuroendocrine tumors with or without carcinoid heart disease undergoing catheter ablation at the authors’ institution. Background: Neuroendocrine (carcinoid) tumors are a rare form of neoplasm with the potential for systemic vasoactive effects and cardiac valvular involvement. These tumors can create peri-operative management challenges for the electrophysiologist. However, there are few data regarding ablation outcomes, periprocedural complications, and management of these patients. Methods: All patients with neuroendocrine tumors undergoing catheter ablation at the Mayo Clinic, Rochester, Minnesota over a 25-year period were retrospectively reviewed. From this cohort, the type of arrhythmias ablated, the recurrence of arrhythmia, perioperative complications, and mortality were reviewed and analyzed. Results: A total of 17 patients (52.9% male; mean age 62.4 ± 9.3 years) with neuroendocrine tumors underwent catheter ablation during the study period. Primary tumor sites included the gastrointestinal tract (n = 11), lung (n = 4), ovary (n = 1), and lymph node (n = 1). Nine patients had metastatic disease, 5 of whom were on somatostatin analog therapy at the time of ablation. Three patients had active symptoms of carcinoid syndrome at the time of ablation, and 2 of those patients had carcinoid heart disease. Ablations were performed mainly for atrial arrhythmias (76.5%): atrioventricular nodal re-entry tachycardia (n = 7), atrial fibrillation (n = 4), and atrial flutter (n = 2). Four patients underwent ablation of ventricular arrhythmias. During a mean follow-up of 19.2 ± 26.2 months, arrhythmia recurred in 35.3% of patients. Three patients (17.6%) had periprocedural complications: pericardial effusion (n = 1), groin site hematoma (n = 1), and carcinoid crisis (n = 1). No deaths were noted in the peri-operative period. Conclusions: In a unique cohort of patients with neuroendocrine tumors, catheter ablation was feasible in patients with or without carcinoid syndrome. Carcinoid crisis may occur during the periprocedural period, which can be life-threatening, and a specified protocol for management is important to mitigate this risk.
