Leadless and extravascular cardiac resynchronization therapy: the future for CRT?

Cardiac resynchronization therapy is used to treat dyssynchronous heart failure. Lead-related complications and anatomical constraints can limit pacing lead placement, but leadless systems are now becoming available. These new systems overcome lead-related issues, offering a new option for patients with complex disease (such as congenital heart disease) by eliminating intravascular hardware.
