La interrupción del arco aórtico se define por la falta de continuidad anatómica entre la aorta ascendente y la descendente, considerándose una forma extrema de coartación. Generalmente se encuentra asociada con otras anomalías cardíacas, como puede ser el ventrículo derecho de doble salida. El avance tecnológico en cardio-TC ha permitido en los últimos años una gran precisión diagnóstica con mínimo riesgo para el paciente. Se presenta el caso de un neonato de 4 días de vida con diagnóstico de coartación aórtica compleja estudiado mediante cardio-TC junto con una breve revisión bibliográfica del tema.
Kounis syndrome (KS) is an acute coronary syndrome (ACS) described in relationship with drugs or stents. KS was suspected in a full-term newborn who underwent a Rashkind-atrioseptostomy and stenting that periodically developed episodes of ACS. Skin test with nickel and titanium were performed being negatives. Basophil activation (BAT) and lymphocyte transformation (LTT) tests were performed for the suspected drugs. Non-responder basophils in BAT and a positive LTT for heparin were found. A new dose of heparin was administered by error, after which a new ACS was developed. We described the first report of KS by drug in a newborn.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
