Stent placement to stabilize the left ventricular lead in the coronary sinus

Surgical epicardial left ventricular lead versus coronary sinus lead placement in biventricular pacing.

OBJECTIVE Biventricular pacing has demonstrated improvement in cardiac function in treating congestive heart failure (CHF). Two different operative strategies (coronary sinus vs. epicardial stimulation) for left ventricular (LV) pacing were compared. METHODS Since April 1999, a total of 86 patients (pts, age: 63+/-10 years) with depressed systolic LV function (mean ejection fraction 24+/-9%),...

Long-term experience with coronary sinus side branch stenting to stabilize left ventricular electrode position.

BACKGROUND Despite technical advancements, implantation of coronary sinus (CS) leads may be challenging, and dislocation remains a relevant clinical problem. OBJECTIVE The aim of this study was to investigate the effectiveness, safety, and long-term outcome of stent implantation to anchor the lead to the wall of the CS side branch. METHODS Stenting of a CS side branch was performed in 312 p...

Left ventricular lead placement in the latest activated region guided by coronary venous electroanatomic mapping.

AIM Left ventricular (LV) lead placement in the latest activated region is an important determinant of response to cardiac resynchronization therapy (CRT). We investigated the feasibility of coronary venous electroanatomic mapping (EAM) to guide LV lead placement to the latest activated region. METHODS AND RESULTS Twenty-five consecutive CRT candidates with left bundle-branch block underwent ...

Interaction of intraluminal tissue and coronary sinus lead stabilized with stent placement.

INTRODUCTION The aim of our investigation was to examine the intraluminal interaction of the vascular tissue and the implanted coronary sinus lead stabilized with stent on two human hearts removed before transplantation. METHODS AND RESULTS The coronary sinus lumen was sectioned under operational microscope and opened carefully. The leads and stents were found separately positioned beside eac...
