[Pacemakers and cardiac resynchronization therapy : recent advances]

Several innovations have expanded the treatment options for antibradycardia pacing and cardiac resynchronization therapies. Among them, leadless pacemakers represent an alternative to conventional transvenous pacemakers and are typically offered to patients with difficult venous access or at increased risk of infection. In addition, more physiological pacing techniques delivered at the level of the cardiac conduction system, particularly the left bundle branch of the His bundle, are now fully established in clinical practice. Besides, the concept of cardiac resynchronization has evolved : conduction system pacing now appears to be an alternative to "conventional" biventricular pacing. This article summarizes recent advances in cardiac pacing and resynchronization therapy.
