Fulminant cytomegalovirus myocarditis in an infant with concomitant large atrial and ventricular septal defects: medical intervention strategy for functional cardiac regeneration

Abstract

A cytomegalovirus-associated heart failure in a young infant with atrial and ventricular septal defects is reported in this case report. The patient recovered by an anti-congestive and anti-viral therapy with an extra percutaneous transcatheter treatment strategy. In the context of bi-ventricular predominant right heart failure associated with supra-systemic pulmonary hypertension, the already closed arterial duct was re-opened and stented to unload the right ventricle and thereby augment the systemic blood flow. Either the left-to-right shunting atrial septal defect or bi-directional shunting ventricular septal defect was involved in the disease process and was not able to avoid global heart failure. After clinical improvement, the stented duct was shunted left-to-right and was occluded with an ADO-II-AS. During the same procedure the atrial septal defect was closed with an Amplatzer-ASD occluder, while the peri-membranous ventricular septal defect was closed with an ADO-II occluder 2 months later.
