Hypothesis-generating for insulation failure with side-by-side polyurethane leads in tight costoclavicular space; prospective data needed before practice change.
Case Report (n=1)
Insertion of polyurethane leads through a tight costoclavicular region should be avoided to prevent delayed lead failure from mechanical stress.
F. Earl Fyke (1988) conducted a case report in Pacemaker lead implantation (n=1). Side-by-side subclavian placement of two polyurethane leads was evaluated on Lead failure and insulation deterioration. Side-by-side placement of two polyurethane leads through a restrictive costoclavicular space resulted in simultaneous insulation deterioration at 11 months and complete lead failure at 16 months.
