Biventricular pacing as bridge to rapid recovery in infancy.
The authors present the unique case of an 8-month-old baby diagnosed with severe left ventricular failure of unknown etiology. Due to a lack of organ availability for this age, a mechanical assist device and assessment for cardiac transplantation were not offered. Subsequent comprehensive echocardiographic dyssynchrony assessment and the presence of left bundle branch block were suggestive of response to cardiac resynchronization therapy. Dual-chamber epicardial pacing was initiated, resulting in prompt marked clinical and echocardiographic improvement, which continued until complete normalization of cardiac function. The pacing system was safely turned off 6 months after its implantation. In conclusion, cardiac resynchronization therapy should be considered as a treatment option even in infancy, regardless of the etiology of disease and/or patient age.
