May enable leadless CRT where conventional systems fail; hypothesis-generating and requires prospective validation before practice change.
Does the combination of Micra and WiSE-CRT systems provide feasible and effective totally leadless cardiac resynchronization therapy in patients with heart failure?
The combination of Micra and WiSE-CRT systems is technically feasible for delivering totally leadless CRT, significantly reducing QRS duration and improving left ventricular ejection fraction.
