bull Reverse PDAs are usually large providing no resistance to blood flowndash Ductus is often as large in diameter as the great vessels it
connects
bull increase in pulmonary artery pressure combined with the increase in pulmonary blood flow creates pathologic responses in the pulmonary arteries over time
bull a continuous murmur is heard during the first days to weeks of life but disappears before the eighth week
bull Often do well until polycythemia develops late in life
Reverse PDAReverse PDA
Treatmentbull Ligation of right to left shunting PDA results in death
due to pulmonary hypertensionndash Has been ligated in stages without causing deathndash Cyanosis and symptoms usually persist
bull Managed Medically by periodic phlebotomyndash Remove 10 mllb and replace with IV fluidsndash Eliminate hyperviscosity without inducing hypoxiandash Goal for PCV is 60-65ndash Excellent blood for RBC transfusion -)ndash Repeat when clinical signs return

Pericardial EffusionPericardial Effusion
Echocardiographic Abnormalitiesbull Careful to distinguish pericardial from pleural
effusionndash Pericardium not visualized with pleural effusionndash Collapsed lung lobes may be seen with pleural
effusion (look like liver in US)ndash Careful not to confuse consolidated lung with liver in
a peritineopericardial diaphragmatic herniabull Heart may swing back amp forth in the
pericardium

Echocardiographic Abnormalitiesbull Cardiac tamponade
ndash Compression of RVndash Diastolic collapse of RVndash IVS may be flattened with paradoxical motionndash Pericardiocentesis is imperativendash Aggressive diuresis will reduce preload
