578 right ventricle (RV); however, in patients at high risk of cardiac surgery, we offer an alternative interventional approach that involves stent‐ ing of significant subpulmonary stenosis. This is achieved by utilizing an arterial approach through the right aortic arch, patent arterial duct, and, finally, through the RVOT. We present a case of a newborn delivered at term, with a body weight of 2900 g. A pulse oximetry test showed a mild desaturation of 85%, and transthoracic echocardiography re‐ vealed a diagnosis of TOF, for which prostaglan‐ din E1 infusion was initiated. The patient was then transferred to our center, where we con‐ firmed the diagnosis of TOF with restrictive ven‐ tricular septal defect, significant subpulmonary stenosis with suprasystemic RV pressure, right Patients with tetralogy of Fallot (TOF) have impaired pulmonary flow due to an obstruct‐ ed right ventricular outflow tract (RVOT), pul‐ monary valve or supravalvular stenosis, or hy‐ poplastic pulmonary arteries. In newborns, al‐ prostadil infusion provides the patency of the ar‐ terial duct, ensuring adequate pulmonary flow. As the next stage of treatment, some children may be referred for Blalock–Taussig or central aortopulmonary anastomosis as well as Brock operation with relief of RVOT obstruction.1‐3 However, in some cases, interventional proce‐ dures including balloon valvuloplasty, RVOT, or arterial duct stent implantation seem to be the best option. Conventionally, the RVOT stenting pathway is from the side of the severely hypertrophied Correspondence to: Jacek Kuźma, MD, PhD, Department of Pediatric Cardiology, University Children’s Hospital, Jagiellonian University Medical College, ul.
