Congenital Heart Defects
Congenital Defect | Classification |
---|---|
Atrial Septal Defect | Acyanotic - Increased Pulmonary Blood Flow. Hole in septum between both atria, signs on CHF. Increasded risk for endocarditis |
Ventricular Septal Defect | Acyanotic - Increased Pulmonary Blood Flow. Hole between both ventricles, signs of CHF. Increased risk for endocarditis |
Patent Ductus Arteriosis | Acyanotic - Increased Pulmonary Blood Flow. Ductus Arteriosis does not close, blood leaks back into pulmonary artery. Increased risk for endocarditis. |
Coartication of Aorta | Acyanotic - Obstructive Blood flow in the aorta (to systemic circulation) and backs up in the left side of the heart |
Aortic Valvar Stenosis | Acyanotic - Obstructive Blood Flow from left ventricle (to systemic circulation) and backing up in the lungs |
Pulmonic Valvar Stenosis | Acyanotic - Obstructive Blood flow from right ventricle (to the lungs) backing up blood systemically |
Tetralogy of Fallot | Cyanotic - Decreased pulmonary blood flow. 4 Defects- Ventricular setal defect, pulmonic stenosis, right ventricular hypertrophy, over-riding aorta. Causes mixed sign depending on where pressure is greatest, can become acutely cyanotic "Blue or Tet Spell" |
Tricuspid Atresia | Cyanotic - Decreased Pulmonary blood flow. No valve between R atrium & R ventricle. Venous blood backs up. Blood flows from left atrium through foramen ovale or Atrial septal defect into L atrium. |
Transposition of Great Arteries | Cyanotic - Mixed Blood Flow. Pulomary artery leaves L ventricle & aorta leaves R ventricle. Requires PDA or ASD or VSD for survival (or there will not be exchange of blood) |
Hypoplastic Left Heart Syndrome | Cyanotic - Mixed Blood Flow.Under developed L side of heart, requires a patent foramen ovale and PDA for survival. Will need a heart transplant, high mortality rate even with transplant |
Total Anomalous Pulmonary Venous Return | Cyanotic - Mixed Blood Flow. VERY rare! |
