Common diagnoses included tetralogy of Fallot (50%) and double\u2010outlet right ventricle (25%). In all, the indication was cyanosis. Reasons to defer surgery included low weight (37.5%), preference for complex operation at older age (31.25%) and significant comorbidity (18.75%). Following valvuloplasty, significant increases in oxygen saturation (83.1\u2009\u00b1\u20098.8 vs. 74.7\u2009\u00b1\u20098.7%, <jats:italic>P<\/jats:italic>\u2009=\u20090.008) and <jats:italic>Q<\/jats:italic><jats:sub>P<\/jats:sub>:<jats:italic>Q<\/jats:italic><jats:sub>S<\/jats:sub> (1.6\u2009\u00b1\u20090.5 vs. 0.8\u2009\u00b1\u20090.3, <jats:italic>P<\/jats:italic>\u2009=\u20090.0005) occurred.
