Efficient approach to superior vena cava baffle stenosis following the Mustard procedure: Expanding the role of a mechanical rotating dilator sheath for lead extraction.

Use of the mechanical rotating dilator sheath is an evolving treatment strategy in adult congenital heart disease to minimize the risk of bleeding, trauma to surrounding structures, and death. Its ability to fully alleviate baffle stenosis even when full lead extraction is not feasible or is associated with significant procedural risk, further demonstrates its expanded role in this patient population. A multidisciplinary approach and great diligence must be employed to avoid potential complications.
