Right ventricular outflow tract stenting : effective palliation for Fallot’s tetralogy

Abstract

Traditionally, the management of infants with Fallot’s tetralogy (TOF) with excessively reduced pulmonary flow and cyanosis has been palliation until or unless complete repair is feasible. Palliation involves a procedure that augments pulmonary flow. Most series recognise two subgroups of patients at high risk even in the current era: the cyanotic neonate/infant with small pulmonary arteries and those with complex anatomical variants of tetralogy and/or significant comorbidities such as additional congenital heart lesions (e.g associated Atrio Ventricular Septal Defect) or other congenital anomalies. There is an argument for palliation of these high-risk groups to allow for future potentially more effective elective repair
