Pulmonary Atresia With Intact Ventricular Septum

Pulmonary atresia with intact ventricular septum is a rare congenital heart disease comprising less than 1% of all heart defects, characterized by membranous or muscular atresia of the right ventricular outflow tract without any ventricular communication, often involving underdevelopment of the right ventricle and tricuspid valve. Newborns with pulmonary atresia with intact ventricular septum frequently exhibit cyanosis and desaturation, especially after the closure of the patent ductus arteriosus, which is crucial for their pulmonary circulation. Physical examination may reveal single first and second heart sounds, a pansystolic murmur if the tricuspid valve regurgitates, and possibly a murmur from the patent ductus arteriosus. This course explores the complexities of this condition, including anatomical considerations, pathophysiology, and nuances of treatment that must be highly individualized based on the characteristics of the right ventricle and tricuspid valve, as well as the anatomy of the coronary arteries. This activity for healthcare professionals is designed to enhance the learner’s competence in identifying pulmonary atresia with intact ventricular septum, performing the recommended evaluation, and implementing an appropriate interprofessional approach when managing this condition.
