Managing Challenges in a Symptomatic Patient with Moderate Pulmonary Stenosis: A Case Report

Introduction: Pulmonary stenosis is a common form of obstruction in the right ventricular outflow tract, characterized by the narrowing of the pulmonary valve, which results in obstructed blood flow. Case Presentation: A 17-year-old female presented with recurring shortness of breath, chest pain, and palpitations, especially during physical activity. On examination, a grade III/VI continuous murmur was heard at the upper left sternal border. Echocardiography confirmed moderate pulmonary valve stenosis, a left-to-right patent ductus arteriosus (PDA), and mild to moderate pulmonary regurgitation.
