Unusual fracture of cardiac pacing electrode.
This report describes a patient with an epicardial demand pacing system in whom pacing failure two months after implantation was found to be due to a fracture of the helical wire electrode within its supporting structure. We know of no report of this site of failure of a Cordis 323-451 or similar electrode.
متن کاملPermanent cardiac pacing in children: choosing the optimal pacing site: a multicenter study.
BACKGROUND We evaluated the effects of the site of ventricular pacing on left ventricular (LV) synchrony and function in children requiring permanent pacing. METHODS AND RESULTS One hundred seventy-eight children (aged <18 years) from 21 centers with atrioventricular block and a structurally normal heart undergoing permanent pacing were studied cross-sectionally. Median age at evaluation was ...
متن کاملCoronary sinus dissection during left ventricular pacing electrode implantation.
Coronary sinus (CS) dissection during biventricular pacing electrode implantation is a complication that rarely develops. A 71-year-old female with recurrent ventricular tachycardia, heart decompensation, and poor left ventricular function because of dilated cardiomyopathy was admitted for the implantation of a cardioverter-defibrillator for biventricular pacing. During the operation, we experi...
متن کاملThree-dimensional mapping of optimal left ventricular pacing site for cardiac resynchronization.
BACKGROUND The efficacy of cardiac resynchronization therapy (CRT) depends on placement of the left ventricular lead within the late-activated territory. The geographic extent and 3-dimensional distribution of left ventricular (LV) locations yielding optimal CRT remain unknown. METHODS AND RESULTS Normal or tachypacing-induced failing canine hearts made dyssynchronous by right ventricular fre...
متن کاملSingle site left ventricular pacing for cardiac resynchronization.
Chronic, dilated heart failure is often accompanied by delayed ventricular electrical activation manifested as prolonged QRS duration, most commonly in the form of left bundle branch block (LBBB). Exploration of the link between the sequence of cardiac electrical activation and mechanical function is one of the most exciting contemporary areas of research in heart failure, but recognition of th...
