Key result
CRT effectively treats pediatric PICM but requires individualized assessment in DCM and CHD.
Why the study?
While CRT is established for adult heart failure and pediatric pacemaker-induced cardiomyopathy, its efficacy in pediatric dilated cardiomyopathy and congenital heart disease remains unestablished and challenging to standardize into guidelines.
Does cardiac resynchronization therapy improve heart failure in pediatric and congenital heart disease patients?
Does cardiac resynchronization therapy improve heart failure in pediatric and congenital heart disease patients?
While CRT is an established treatment for pacemaker-induced cardiomyopathy in children, its use in pediatric DCM and congenital heart disease cannot simply follow adult guidelines and requires individualized evaluation.
CRT supports selective use in pediatric pacemaker-induced cardiomyopathy; application in DCM and CHD leaves optimal indications open.
心臓再同期療法（crt）は，デバイスを用いて心不全を治療する方法である．成人では心不全の治療法の一つとして確立している．成人では拡張型心筋症（dcm）患者に多く用いられているが，小児のdcmに対するcrtの効果については確立していない．小児の完全房室ブロックに対するペースメーカ治療で，心室リードが右室自由壁や右室流出路に留置されていることが原因でペースメーカ誘発性心筋症を発症することがある．小児のペースメーカ誘発性心筋症に対してのcrtの効果は確立されている．それ以外の小児や先天性心疾患（chd）に対するcrtについても有効であるという報告は散見されるが，小児やchd症例は，その特殊性や多様性からcrtのガイドライン化は困難であり，症例ごとにその適応を十分検討する必要がある．

Tsugutoshi Suzuki (2023) conducted a review in Heart failure in pediatrics and congenital heart disease. Cardiac Resynchronization Therapy (CRT) was evaluated. Cardiac resynchronization therapy is effective for pacemaker-induced cardiomyopathy in children, but its application in pediatric dilated cardiomyopathy and congenital heart disease requires individualized assessment.
