Absent Pulmonary Valve Syndrome (APVS) is a rare variant and makes up about 3-6% of patients of Tetralogy of Fallot (ToF).1 Apart from the hallmark features of ToF, these patients have an absent/rudimentary pulmonary valve, leading to pulmonary regurgitation during foetal life, causing aneurysmal dilatation of pulmonary vessels, compressing the trachea or the main stem bronchi, and leading to tracheomalacia and bronchomalacia.
