Left atrial appendage occlusion devices; Additionally, there are, at times, indications to remove these devices and extraction (ie, removal) of these devices can also be performed by electrophysiologists. Once implanted, long-term clinical follow up and reprogramming of implanted devices also falls to the electrophysiologist.
There is growing evidence that left atrial appendage occlusion therapy may reduce the risk of stroke in people with non-valvular AF as much as warfarin. [154] [155] The addition of left atrial appendage isolation to catheter ablation has reduced AF recurrence by 80% in patients with persistent AF. [156]
None of the present energy sources—including cryotherapy, unipolar radiofrequency, irrigated radiofrequency, bipolar radiofrequency, microwave, and laser energy—are capable of creating the left atrial isthmus lesion from the epicardial surface, because of the necessity of penetrating through the circumflex coronary artery to reach the left ...
Cardiac resynchronisation therapy (CRT or CRT-P) is the insertion of electrodes in the left and right ventricles of the heart, as well as on occasion the right atrium, to treat heart failure by coordinating the function of the left and right ventricles via a pacemaker, a small device inserted into the anterior chest wall.

“They told us as soon as they gave us the diagnosis that pretty much the only course of treatment would be to get a hemispherectomy, which is a surgery to remove the left side of the brain ...
