Fístula de artéria coronária direita com insuficiência cardíaca congestiva em neonato: diagnóstico ecodopplercardiográfico e tratamento por oclusäo com baläo descartável / Right coronary artery fistula with congestive heart failure in the neonate: Doppler echocardiographic diagnosis and closure with detachable balloon

ABSTRACT

We report here a case of coronary artery fistula in a neonate with clinical signs of heart failure. The electrocardiogram showed signs of left ventricular hypertrophy and diffuse alterations in ventricular repolarization. Chest X-ray showed an enlargement of the cardiac silhouette with an increase in pulmonary flow. After echocardiographic diagnosis and angiographic confirmation, closure of the fistulous trajectory was performed with a detachable balloon with an early and late successful outcome.
