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

Temporary biventricular pacing to treat low output states after cardiac surgery is an active area of investigation. Reoperative cases are not studied due to adhesions, which preclude left ventricular mobilization to place epicardial pacing wires. In such patients, inserting a temporary left ventricular lead via the coronary sinus cardioplegia cannula may allow for biventricular pacing. We developed a novel technique for intraoperative left...
