Background: Bundle branch reentrant ventricular tachycardia (BBR-VT) is a rare form of VT occurring in patients with structural heart disease (SHD). Rarely, it can also occur in the absence of SHD. Understanding its clinical and electrophysiologic (EP) properties and outcomes post-catheter ablation (CA) is crucial. Objective: We describe a case series of patients diagnosed with BBR-VT regarding clinical and EP characteristics, as well as long term follow-up after CA. Methods: All cases of BBR-VT that were diagnosed during EP study in our lab were evaluated. Clinical characteristics and EP findings were described. Results: Sixteen patients (12/16 male; mean age 50±21) with BBR-VT were studied from 2009-2020, with a mean follow-up of 70±16 months. Notably, nearly half (7; 43%) had no SHD. Patients without SHD (7; 43%) had Steinert dystrophy (3/7), SCN5A mutations (2/7), ajmaline-induced (1/7) or idiopathic BBR-VT (1/7). We suggest an algorithm for the evaluation of patients with BBR-VT without SHD. The induced BBR VT had a mean cycle length of 322±22 ms, was well tolerated in 10/16. A RBB CA was performed with an 8 mm solid-tip catheter. The HV interval increased from 72±9 to 100±23 ms. One patient developed total AV block. After the procedure, either a dual chamber pacemaker (10/16) or an ICD (3/16) was implanted. No patient presented VT recurrence. Conclusion: Although traditionally associated with patients with dilated cardiomyopathy, our study demonstrates that nearly half of BBR-VT cases occur in patients with structurally normal hearts. Once these patients are identified, Steinert’s disease should be considered as a potential underlying condition. . In the absence of ocular abnormalities, genetic testing may be warranted, particularly in the attempt to identify SCN5A mutations. Right bundle branch ablation is effective in most cases; however, device implantation is often required to ensure optimal long-term management.
