Heart ablation is moving beyond heat and cold, and the medtech race is getting much bigger

Pulsed field ablation is changing atrial fibrillation treatment by using extremely short electrical pulses to disrupt targeted cardiac cells instead of relying primarily on heat or freezing. Boston Scientific, Medtronic, Abbott Laboratories and Johnson & Johnson now compete across multiple FDA-approved PFA platforms, while new trials are pushing the technology into persistent atrial fibrillation, broader lesion sets and potentially earlier treatment.

Leadless pacemakers: How tiny implants inside the heart are challenging cardiac leads

Leadless pacemakers are moving beyond a niche alternative for selected patients. Abbott’s AVEIR DR can pace both the right atrium and right ventricle using two communicating intracardiac devices, while Medtronic is extending battery life and Boston Scientific is developing a wireless pacemaker-defibrillator system. The technology removes the chest pocket and transvenous leads that create important complications in conventional pacing, but retrieval, long-term device accumulation, patient selection and the limits of current pacing modes still stand between leadless systems and wholesale replacement of traditional pacemakers.
