Emergency Cardiac Resynchronisation in a 4 kg Infant Post Surgical Closure of Ventricular Septal Defect

Cardiac resynchronisation therapy (CRT) is an established treatment for adult patients with cardiac failure due to mechanical and electrical dyssynchrony. Data on CRT in infants are scarce. We report the remarkable success of emergent CRT by epicardial pacing of the left ventricular apex in a 4 kg infant with left ventricular failure due to LV dyssynchrony from left bundle branch block.
