Biventricular pacing for treating heart failure in children:A case report and review of the literature

摘要

BACKGROUND Cardiac resynchronization therapy(CRT)can be used as an escalated therapy to improve heart function in patients with cardiac dysfunction due to long-term right ventricular pacing.However,guidelines are only targeted at adults.CRT is rarely used in children.CASE SUMMARY This case aimed to implement biventricular pacing in one child with heart failure who had a left ventricular ejection fraction<35%at 4 years after implantation of an atrioventricular sequential pacemaker due to atrioventricular block.Postoperatively,echocardiography showed atrial sensing ventricular pacing and QRS wave duration of 120-130 ms,and cardiac function significantly improved after upgrading pacemaker.CONCLUSION Patients whose cardiac function is deteriorated to a level to upgrade to CRT should be upgraded to reverse myocardial remodeling as soon as possible.
