Early-BYRD: alternative early pacing and defibrillation lead replacement avoiding venous puncture.

BACKGROUND

In cases of lead failure after implantation of pacemakers (PM) or implantable cardioverter defibrillators (ICD) early lead replacement may be challenging. Puncture of the subclavian vein bears possible complications such as pneumothorax, hematothorax, and damage of leads to be left in place. To avoid venous puncture PM or ICD leads were replaced using a flexible polypropylene sheath (Byrd-sheath).

METHOD

From January 2010 through December 2017, 55 patients underwent early lead exchange avoiding venous puncture. Early lead exchange for this study was defined as a reintervention within 14 days after the initial lead implantation. The connector of the malfunctioning lead was cut off, and stabilized by a stiff stylet. After having cut off the plastic knob of the stylet, the lead was passed through the polypropylene sheath and the latter advanced into the subclavian vein with gentle rotational movements to gain access to the subclavian vein. After lead removal the polypropylene sheath was replaced by a peel away sheath a new lead inserted.

RESULTS

Overall, 23 defibrillation leads and 34 pacing leads (16 right atrial leads, 17 right ventricular leads, and 1 left ventricular lead) were successfully explanted. Access to the subclavian vein was uneventful, and blood loss minimal. Radiation exposure and fluoroscopy time were also negligible.

CONCLUSION

The Byrd-sheath technique proved to be safe and successful in providing vein access within 2 weeks after initial lead implantation using the previously implanted lead and thus avoiding puncture of the subclavian vein.
