Abstract
Introduction: Right bundle branch block (RBBB) following cardiac device extraction has not been previously reported but may have catastrophic consequences.
Methods and results: We present two cases of young male patients who developed RBBB following the extraction of single chamber TV ICD systems where the coil was adherent close to the superior tricuspid valve annulus. Both patients had a subcutaneous ICD (SICD) implanted but suffered an inappropriate shock due to T-wave oversensing, requiring very early SICD removal for one patient.
Conclusion: The development of RBBB following the extraction of a TV ICD is a previously unreported complication and may cause significant sensing problems if an SICD is implanted subsequently. Placement of the ICD lead tip in the right ventricular outflow tract or high on the intraventricular septum may predispose to this complication.
