Study Notes
Atrial Septal Defect (ASD)
- Shunting: Left-to-right shunting between the atria
- Most Common Type: Ostium secundum, often associated with Down syndrome
- Signs: Wide, fixed split S2, systolic ejection murmur at the left upper sternal border (LUSB)
- Imaging: Cardiomegaly, increased pulmonary vasculature on chest X-ray (CXR)
- Treatment: Observation for small defects; surgical or percutaneous closure for symptomatic cases
Coarctation of the Aorta
- Description: Narrowing of the aortic arch, increasing afterload
- Associated Conditions: Turner syndrome, bicuspid aortic valve
- Signs: Upper extremity hypertension (HTN), lower extremity hypotension, diminished femoral pulses, claudication
- Imaging: Rib notching, "3 sign" on CXR
- Treatment: Balloon angioplasty, stent placement, or surgical repair
Patent Ductus Arteriosus (PDA)
- Description: Persistent ductus arteriosus after birth, causing left-to-right shunting
- Associated Conditions: Prematurity, congenital rubella
- Signs: Continuous "machine-like" murmur at LUSB, bounding pulses
- Treatment: Nonsteroidal anti-inflammatory drugs (NSAIDs) like indomethacin or ibuprofen to close; surgical ligation if medication is ineffective
Patent Foramen Ovale (PFO)
- Description: Failure of the foramen ovale to close, potentially causing right-to-left shunting
- Symptoms: Often asymptomatic; can lead to paradoxical embolism or cryptogenic stroke
- Diagnosis: Bubble study on echocardiography (echo)
- Treatment: Closure if symptomatic or if stroke occurs
Tetralogy of Fallot (TOF)
- Characteristics: A combination of four defects: Pulmonary stenosis, Right Ventricular Hypertrophy (RVH), Overriding aorta, Ventricular septal defect (VSD)
- Signs: Cyanosis, "tet spells" (episodic cyanosis) relieved by squatting, harsh systolic murmur at LUSB
- Imaging: "Boot-shaped" heart on CXR
- Treatment: Surgical repair; prostaglandin E1 (PGE1) to maintain ductal patency before surgery
Transposition of the Great Vessels (TGV)
- Description: Aorta and pulmonary artery are switched, a cyanotic heart defect.
- Associated Conditions: Diabetic mothers
- Signs: Severe cyanosis at birth, single loud S2
- Imaging: "Egg on a string" appearance on CXR
- Treatment: Surgical arterial switch; PGE1 to maintain ductal patency
Ventricular Septal Defect (VSD)
- Description: Left-to-right shunting through a septal defect
- Frequency: Most common congenital heart defect, associated with trisomies
- Signs: Harsh holosystolic murmur at the left lower sternal border (LLSB)
- Diagnosis: Echocardiography (echo) to visualize the defect
- Treatment: Observation for small defects; surgical repair for symptomatic or large defects
