Left ventricular pacing lead insertion via the coronary sinus cardioplegia cannula: A novel method for temporary biventricular pacing during reoperative cardiac surgery

Intraoperative biventricular pacing with a left ventricular pacing lead inserted via the coronary sinus cardioplegia cannula is feasible, using standard instrumentation and without requiring cardiac manipulation. This approach merits further study in patients undergoing reoperative cardiac surgery.
