The historical retained guidewire technique for coronary sinus lead stabilization during CRT can lead to severe mechanical complications, reinforcing the need to abandon this practice and refer affected patients to experienced extraction centers.
May warrant referral to experienced extraction centers; leaves open the true incidence of these complications.
Our case reinforces that the retained guidewire technique should be abandoned for coronary sinus lead stabilization during cardiac resynchronization therapy. Although rarely encountered today, patients previously implanted using historical methods may present with severe mechanical complications and high-risk extraction profiles. Early recognition and referral to experienced lead extraction centers is essential.
