A 10-year-old female patient diagnosed with isolated type I aortopulmonary window and severe pulmonary arterial hypertension who underwent repair of the aortopulmonary window via Johansson's transwindow approach using a unidirectional, fenestrated, valved, aorticopulmonary patch. The preoperative pulmonary vascular resistance was 9.0 Woods units/m2 that reduced to 4.0 Woods units/m2 after oxygen (100%) and nitric oxide (80 ppm) administration. The postoperative recovery was uneventful.
