We report on the magnetic resonance imaging (MRI) findings in a baby who developed marked right ventricular outflow track obstruction after valvuloplasty. MRI showed myocardial hypertrophy in the infundibular region, excluding the need for urgent surgical intervention.[SDGs]SDG3aorta subvalvular stenosis; article; case report; diagnostic imaging; diagnostic value; female; heart right ventricle hypertrophy; heart right ventricle outflow tract obstruction; human; newborn; nuclear magnetic resonance imaging; postoperative complication; preoperative evaluation; pulmonary valve diseasejournal article2-s2.0-0033780246
