In this episode of Deep Dive Nursing, we explore the essentials of pediatric cardiovascular conditions—starting with fetal circulation and the critical transition to normal blood flow after birth. We break down the differences between congenital and acquired heart diseases, covering key defects such as acyanotic, cyanotic, and obstructive congenital anomalies. We also examine acquired conditions like Kawasaki disease, rheumatic fever, and infective endocarditis. Tune in for a detailed look at diagnostic tools, nursing interventions, and medication management, including the use of digoxin and indomethacin. Perfect for nursing students and professionals seeking a comprehensive yet practical guide to pediatric cardiac care.
