Cardiac Resynchronization Therapy in Pediatric and Congenital Heart Disease


Cardiac resynchronization therapy (CRT) is an emerging option for treating dyssynchrony-associated heart failure in patients with pediatric or congenital heart disease. CRT has proved beneficial for both the acute manipulation of cardiac output after surgery for congenital heart defects and for the management of chronic systemic ventricular failure. Although there are no prospective and randomized trial data, retrospective series show that CRT is similarly effective for managing dyssynchrony-associated heart failure in this younger population as it is for treating adults with ischemic and idiopathic dilated cardiomyopathy. The heterogeneity of anatomical and functional substrates in which CRT shows efficacy calls for further studies defining the usefulness of CRT in specific subgroups of patients.
