“…Regardless of being just a feasibility study, the modifications observed in the follow-up of patients submitted to left sympathetic blockade were similar to those documented with other well established approaches in the treatment of chronic heart failure [15][16][17] . Furthermore, as a phase I clinical trial, the current experience represents a conservative approach in the surgical achievement of a sympathetic blockade.…”

“…Similar to other palliative treatments of heart failure, mortality in the follow -up can occur by different complications [15][16][17] . The occurrence of two late deaths due to myocardial infarction or pulmonary thromboembolism in this series was probably related to the underlying disease and not to the procedure itself.…”

“…This ratio is much lower than the rate of reoperation reported in the literature in large multicenter studies. 1,21,22 Potential complications due to CS stent implantation may be the injury of the target vein and/or mechanical damage of the electrode. Our observations are in line with prior case reports that describe no complications during stent implantation into the venous system of the heart [23][24][25] or during stenting to fix the attained 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. METHODSStenting of a CS side branch was performed in 312 patients. The procedure was performed because of postoperative lead dislocation in 16 patients and because of an intraoperative unstable lead position or phrenic nerve stimulation in 296 cases. A bare metal coronary stent was introduced over a second guide wire in the same CS sheath. The stent was deposited 5-35 mm proximal to the most proximal electrode. Mechanical damage of the CS side branch or pericardial effusion was not observed owing to stenting. RESULTSDuring follow-up (median 28.4, interquartile range 15-37, maximum 70 months), a clinically important increase in the left ventricular pacing threshold was found in four cases and reoperation was necessary in only two patients (0.6%). Phrenic nerve stimulation was observed in 18 instances, and repositioning with an ablation catheter was performed in seven cases. Impedance measurements did not suggest lead insulation failure. Three stented leads were extracted without complication after 3-49 months owing to infection, while four leads were extracted easily during heart transplantation after 7-27 months.CONCLUSION Stent implantation to stabilize CS lead position seems to be an effective and safe procedure in prevention and treatment of CS lead dislocation in selected cases.KEYWORDS Cardiac resynchronization; LV lead implantation; Coronary sinus; Lead dislocation; Stent implantation ABBREVIATIONS CRT ϭ cardiac resynchronization therapy; CS ϭ coronary sinus; INR ϭ international normalized ratio; LV ϭ left ventricle; NYHA ϭ New York Heart Association; PNS ϭ phrenic nerve stimulation (Heart Rhythm 2011;8:845-850)

Systematic Review: Cardiac Resynchronization in Patients with Symptomatic Heart Failure

Abstract: In selected patients with heart failure, cardiac resynchronization therapy improves functional and hemodynamic status, reduces heart failure hospitalizations, and reduces all-cause mortality.
