Atrial Septal Defect (ASD)
- Hole in Septum between the Atria
 - Often Asymptomatic
 - Wide and Fixed Split S2
 - Cyanosis and Dyspnea
 - Easily Fatigued
 - Chest X-ray shows Increased Pulmonary Vascular Markings
 - Echocardiogram
 - Surgery if CHF as Child
 - Antibiotic Prophylaxis 
 - Most Close Spontaneously
 
Ventricular Septal Defect (VSD)
- Opening at Intraventricular Septum
 - Most Common Congenital Heart lesion
 - High-pitched Holosystolic Murmer (over left sternal border)
 - Dyspnea and Respiratory Distress
 - Loud Pulmonic S2
 - Echocardiogram
 - Small VSDs Close Spontaneously
 - Large VSDs Require Surgery
 - Endocarditis
 - Eisenmenger's Syndrome
 - CHF
 
Patent Ductus Arteriosus
- Continuous
 - Machine like murmur
 - Often Due to Congenital Rubella
 - Prematurity
 
Persistent Truncus Arteriosus
- Common Arterial Trunk
 - Single Trunk Emerges from Both Ventricles
 - Cyanosis
 - Pulmonary Congestion
 - Heart Failure
 - Single S2 Sound
 - Echocardiogram
 - Chest X-ray
 - Early Surgical Correction
 - Avoids Pulmonary Hypertension
 
Tetralogy of Fallot (TOF)

 - Echocardiogram
 - Surgical Correction
 
Transposition of Great Vessels
- Pulmonary and Systemic Circulation are in Parallel
 - Incompatible with Life Without a Shunt
 - Severe Cyanosis at Birth
 - Single S2 sound
 - Echocardiogram
