Percutaneous management of superior vena cava syndrome in patients with cardiovascular implantable electronic devices.

BACKGROUND

There is no consensus regarding the optimal management of cardiovascular implantable electronic device (CIED)-related superior vena cava (SVC) syndrome.

OBJECTIVE

We report our experience with transvenous lead extractions (TLEs) in the setting of symptomatic CIED-related SVC syndrome.

METHODS

We reviewed all TLEs performed at a high-volume center over a 14-year period and identified patients in which TLE was performed for symptomatic SVC syndrome. Patient characteristics, extraction details, percutaneous management of SVC occlusions, and clinical follow up data were analyzed.

RESULTS

Over a 14-year period, more than 1600 TLEs were performed. Of these, 16 patients underwent TLE for symptomatic SVC syndrome. The mean age was 53.1 ± 12.8 years, and 9 (56.3%) were men. Thirty-seven leads, with a mean dwell time of 5.8 years (range 2-12 years), were extracted. After extraction, 6 patients (37.5%) received an SVC stent. Balloon angioplasty was performed before stenting in 5 cases (31.3%). There was 1 major complication (6.3%) due to an SVC tear that was managed surgically with a favorable outcome. Eleven patients underwent reimplantation of a CIED. Over a median follow-up of 5.5 years (interquartile range 2.0-8.5 years), 12 patients (75%) remained free of symptoms.

CONCLUSION

Combining TLE with the percutaneous treatment of symptomatic SVC syndrome is a safe and viable treatment strategy.
