Leadless Cardiac Pacemaker as a Novel Intervention Modality for Atrioventricular Conduction Disturbance in Hypertrophic Cardiomyopathy

Henry Sutanto

Abstract


Atrioventricular conduction disturbance is a common complication of cardiovascular diseases, such as hypertrophic cardiomyopathy. Moreover, the most common form of atrioventricular conduction disturbance is atrioventricular block. Until recently, cardiac pacing was considered to be the most reliable long-time management of atrioventricular block. However, cardiac pacemakers have several limitations and complications. When the first generation of leadless pacemakers was invented in the 1980s, it was multi-component. Nowadays, self-contained or single component leadless pacemakers have been developed and have become popular amongst cardiac electrophysiologists. In particular, in 2013, St. Jude Medical developed a novel design for a cardiac pacemaker called the NanostimTM Leadless Pacemaker. In 2015, Medtronic released a smaller leadless pacemaker called the MicraTM Transcatheter Pacing System.1,2 Although NanostimTM and MicraTM represent state of the art technology; a few studies have documented some of their limitations.3-6 More research is needed to confirm and solve these problems
