Defects that increase pulmonary blood flow
ASD (Atrial Septal Defect)
VSD (Ventricular Septal Defect)
PDA (Patent Ductus Artteriosus)
AV Canal (Atrioventricular Canal)
ASD
Atrial Septal Defect
abnormal opening between left and right atria
VSD
Ventricular Septal Defect
abnormal opening between the right and left ventricles
PDA
Patent Ductus Arteriosus
artery connecting the aorta to the pulmonary artery
AV Canal
low ASD and high VSD
allowing blood to flow between all 4 chambers of the heart
Defects that decrease pulmonary blood flow
Tetrology of Fallot (TET or TOF)
Tricuspid Atresia (TA)
TET
Tetrology of Fallot
VSD, Pulmonary stenosis, overriding aorta, RV hypertrophy
TA
Tricuspid Atresia
no development of tricuspid valve
TA with no other defect to compensate is _____
NOT COMPATIBLE WITH LIFE
Defects with obstruction to blood flow
Coarctation of aorta (CoA, coarc)
Aortic Stenosis (AS)
Pulmonic Stenosis (PS)
CoA
Coarctation of aorta
narrowing in the region of ductus arteriosus
AS
Aortic Stenosis
causes blocking of blood flow between left ventricle and aorta
PS
Pulmonic Stenosis
caused by blockage to blood flow from the right ventricle to the pulmonary artery
Defects with mixed blood flow
Transposition of the Great Arteries (TGA)
Total Anaomolous Pulmonary Venous Return (TAPVR)
Truncus Arteriosus (Truncus)
Hypoplastic Left Heart Syndrome (HLHS)
TGA
Transposition of the Great Arteries
the aorta starts from the right ventricle and the pulmonary artery from the left ventricle
TAPVR
Total Anomalous Pulmonary Venus Return
all 4 pulmonary veins do not connect normally to the left atrium. Instead, the 4 pulmonary veins drain abnormally to the right atriumthough an abnormal/anomalous connection
HLHS
Hypoplastic Left Heart Syndrome
underdeveloped LV; the mitral and aortic valves are either completely closed (atretic) or they are small (hypoplastic), the fist part of the aorta is really small
Congenital Cardiomyopathy is a disease of the heart muscle that causes
the heart muscle to become enlarged, thick, or rigid
As cardiomyopathy progresses, the heart becomes
weaker
It is less able to pump blood and maintain a normal electrical rhythm
this can lead to hf or arrhythmias
Most cardiomyopathyies in children are considered _____ or _______.
primary or idiopathic
primary is a disease of the heart muscle itself, caused by another systemic condition
idiopathic means the cause is unkown
If heart defects are left untreated, the result is
HF
heart muscles become damaged, unable to maintain cardiac output, decreased blood flow to kidneys results in fluid over laod and increased workload of the heart
pulmonary and venous congestion result
Clinical Manifestations of HF, impaired myocardial function
Tachycardia Decreased blood pressure
Sweating (inappropriate)
Gallop on ausculation
Decreased urinary output
Fatigue
Weakness
Irritability
Decreased PO
Pale, cool extremities
Weak peripheral pulses
Clinical Manifestations of HF, pulmonary congestion
Tachypnea
Grunting
Dyspnea
Decreased oxygen saturations
Retractions (infants)
Flaring nares
Exercise intolerance
Increased oxygen requirement
Cough, hoarseness
Clinical Manifestations of HF, systemic venous congestion
Weight gain
Hepatomegaly (enlarged liver)
Peripheral edema, especially periorbital
Ascites
Neck vein distention (older children)
