Abstract This case is a rare occurrence of atrial and coronary sinus (CS) lead dislocation 5 years post cardiac resynchronization therapy‐defibrillator (CRT‐D) implantation, thus necessitating a unique approach. The previous lead‐related vein occlusion was dilated with a balloon using methods typically employed in coronary procedures to address stenosis at the lateral branch of the CS, followed by insertion of a new lead. Materials and techniques used in coronary artery interventional procedures can also be applied in cases of CS vein branch stenosis encountered during CRT‐D implantation. This case represents one of the rare procedures performed in this manner.
