Successful treatment of a cardiac resynchronization therapy nonresponder by identifying lead malpositioning.

Successful treatment of a cardiac resynchronization therapy nonresponder by identifying lead malpositioning. Proc (Bayl Univ Med Cent). 2017 Apr;30(2):230-231 Authors: Prasad KV, Akrawinthawong K, Ferreira SW, Mehdirad AA Abstract This case describes some of the commonly overlooked device-related issues in patients who have reportedly failed to respond to cardiac resynchronization therapy (CRT). The case demonstrates voltage-dependent right ventricular capture instead of right atrial capture by a subtly malpositioned right atrial lead. CRT therapy failed to improve symptoms of heart failure and the diagnosis of "CRT nonresponder" was made. With a detailed fact-finding approach, the mechanism behind this nonresponse was identified, and the outcome of CRT was significantly improved with rectification of the problems.
