Abstract

Background: Cardiac resynchronization therapy using a left ventricular (LV) lead inserted via the coronary sinus (CS) improves symptoms of congestive heart failure, decreases hospitalizations, and improves survival. An epicardial LV lead is often placed surgically after a failed percutaneous attempt, but whether it offers the same benefits is unknown.

Objective: The purpose of this study was to determine if patients who receive a surgical LV lead after failed CS lead placement for cardiac resynchronization therapy derive the same benefit as do patients with a successfully placed CS lead.

Methods: A total of 452 patients underwent attempted CS lead insertion. Forty-five patients who had failed CS lead placement and then had surgical LV lead placement were matched with 135 patients who had successful CS lead placement.

Results: No major differences in preoperative variables were seen between groups. Postprocedural complications of acute renal injury (26.2% vs 4.9%, P <.001) and infection (11.9% vs 2.4%, P = .03) were more common in the surgical group. Mean long-term follow-up was 32.4 +/- 17.5 months for surgical patients and 39.4 +/- 14.8 months for percutaneous patients. At follow-up, all-cause mortality (30.6% vs 23.8%, P = .22) and readmission for congestive heart failure (26.2% vs 31.5%, P = .53) were similar between surgical and percutaneous groups. Improvement in New York Heart Association functional class (60.1% vs 49.6%, P = .17) was similar between surgical and percutaneous groups.

Conclusion: Surgical LV lead placement offers functional benefits similar to those of percutaneous placement but with greater risk of perioperative complications, including acute renal failure and infection.
