physio and anatomic problem:
Cyanosis with respiratory distress
Increased pulmonary blood flow
Transposition
physio and anatomic problem:
Cyanosis without respiratory distress
Decreased pulmonary blood flow
Right heart obstruction
physio and anatomic problem:
hypoperfusion
EITHER:
Poor cardiac output
Left heart obstruction
OR
Poor cardiac function
Normal anatomy
physio and anatomic problem:
Respiratory distress with desaturation (not visible cyanosis)
Bidirectional shunting
Complete mixing
physio and anatomic problem:
Respiratory distress with normal saturation
Left-to-right shunting
Simple intracardiac shunt
surgery for tricuspid atresia
Surgery is staged with an initial subclavian artery-to-pulmonary shunt (BlalockTaussig procedure) typically followed by
a two-stage procedure: bidirectional cavopulmonary shunt (bidirectional Glenn) and Fontan procedure
surgery for hypoplastic left heart
surgical repair is staged with the first surgery (Norwood procedure) done in the newborn period.
Subsequent procedures create a systemic source for the pulmonary circulation (bidirectional Glenn and Fontan procedures), leaving the right ventricle to supply systemic circulation
factors affecting PRELOAD
Total blood volume Venous tone (sympathetic tone) Body position Intrathoracic and intrapericardial pressure Atrial contraction Pumping action of skeletal muscle
factors affecting AFTERLOAD
Peripheral vascular resistance
Left ventricular volume (preload, wall tension)
Physical characteristics of the arterial tree (elasticity of vessels or presence of outflow obstruction)
factors affecting contractility
Sympathetic nerve impulses* Circulating catecholamines* Digitalis, calcium, other inotropic agents* Increased heart rate or postextrasystolic augmentation* Anoxia, acidosis† Pharmacologic depression† Loss of myocardium† Intrinsic depression†
