Unit 1575: Pediatric Cardiology Fundamentals

1. Anatomy and Physiology of the Pediatric Heart

1.1 Overview of the Heart Structure

• Basic heart anatomy: chambers, valves, vessels
• Differences between pediatric and adult heart anatomy

1.2 Physiology of the Pediatric Heart

• Cardiac cycle and function in children
• Developmental changes from fetus to neonate to child
• Impact of growth on cardiac output and heart rate

2. Common Congenital Heart Defects in Children

2.1 Atrial Septal Defects (ASDs)

• Definition and types
• Pathophysiology and clinical implications

2.2 Ventricular Septal Defects (VSDs)

• Types and size classification
• Hemodynamic effects

2.3 Tetralogy of Fallot

• Components of the defect
• Cyanotic vs. acyanotic presentations

2.4 Other Congenital Defects

• Patent ductus arteriosus (PDA)
