Successful treatment of a cardiac resynchronization therapy nonresponder by identifying lead malpositioning.
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 nonr...
متن کاملLead extraction: The road to successful cardiac resynchronization therapy.
BACKGROUND Still increasing life expectancy in patients with implanted devices and large number of leads more and more often induce the need to cure the treatment complications or to change especially to cardiac resynchronization therapy (CRT). In order to prevent further complications, the possibility of damaged or redundant leads extraction should be taken into consideration. The aim of the p...
متن کاملImpacted left ventricular lead technique in cardiac resynchronization therapy.
Left ventricular (LV) lead dislodgement is a significant problem in cardiac resynchronization therapy and re-operation is required to rectify the situation. In this case report, we describe a new technique to stabilize an LV lead which is prone to dislodgement by impacting an inactive LV lead in the same cardiac vein.
متن کاملThoracoscopic Left Ventricular Lead Implantation in Cardiac Resynchronization Therapy
Cardiac resynchronization therapy is known to reduce morbidity and mortality in patients with advanced heart failure as a result of dyssynchrony and systolic dysfunction of the left ventricle. Placement of the left ventricular (LV) lead via the coronary sinus can be difficult. When LV lead implantation is difficult, a video-assisted epicardial approach can be a good alternative. Although there ...
متن کاملCardiac Resynchronization Therapy: Lead Positioning and Technical Advances
Cardiac resynchronization therapy (CRT) is a therapeutic option for heart failure patients with a severely reduced left ventricular ejection fraction and left bundle branch block (Cleland et al., 2001). Ventricular resynchronization is achieved by biventricular pacing, usually via electrodes in the right ventricular apex and a left ventricular (LV) electrode positioned in a coronary vein. About...
