Practical approach to implanting left ventricular pacing leads for cardiac resynchronization.
Our approach to implanting cardiac resynchronization therapy (CRT) devices combines an understanding of the anatomy of the failing heart and the coronary veins, standard pacing lead insertion skills, and techniques common to diagnostic cardiac catheterization and interventional cardiology. The method we have devised over the past 5 years has provided CRT safely and effectively to a large volume...
متن کاملNon-contact left ventricular endocardial mapping in cardiac resynchronisation therapy.
BACKGROUND Up to 30% of patients with heart failure do not respond to cardiac resynchronisation therapy (CRT). This may reflect placement of the coronary sinus lead in regions of slow conduction despite optimal positioning on current criteria. OBJECTIVES To characterise the effect of CRT on left ventricular activation using non-contact mapping and to examine the electrophysiological factors i...
متن کاملAlternative techniques for left ventricular pacing in cardiac resynchronization therapy.
Cardiac resynchronization therapy (CRT) is an important treatment modality for a well-defined subgroup of heart failure patients. Coronary sinus (CS) lead placement is the first-line clinical approach but the insertion is unsuccessful in about 5-10% of the patients. In recent years, the number of CRT recipients and the considerable need for left ventricular (LV) lead revisions increased enormou...
متن کاملRepetitive optimizing left ventricular pacing configurations with quadripolar leads improves response to cardiac resynchronization therapy
BACKGROUND This study aimed to investigate whether repetitive optimizing left ventricular pacing configurations (LVPCs) with quadripolar leads (QUAD) can improve response to cardiac resynchronization therapy (CRT). METHODS Fifty-two eligible patients were enrolled and 1:1 randomized to either the quadripolar LV leads (QUAD) group or the conventional bipolar leads (CONV) group. In the QUAD gro...
متن کاملHaemodynamic evaluation of alternative left ventricular endocardial pacing sites in clinical non-responders to cardiac resynchronisation therapy
INTRODUCTION Non response to cardiac resynchronisation therapy (CRT) may be related to the position of the coronary sinus lead. METHODS We studied the acute haemodynamic response (AHR) from alternative left ventricular (LV) endocardial pacing sites in clinical non-responders to CRT. AHR and the interval from QRS onset to LV sensing (Q-LV interval) from four different endocardial pacing sites ...
