**1. Introduction**

Cyanotic congenital heart defects continue to be a cause of significant morbidity and mortality among infants and are an important contributor to neonatal mortality. In the new paediatric cardiac programmes, the majority of these defects are being corrected very early in life, but the repair, whether corrective or palliative, sometimes is difficult to achieve, especially in neonates with complex anatomy or those with risk factors. Right ventricular outflow stenting (RVOT) has emerged as the main bridging procedure in infants who require early interventions, such as neonates who are duct dependent or who are severely cyanosed and have poor anatomy of the right ventricular outflow tract and/or pulmonary arterial tree (hypoplastic branch PAs).
