Congenital heart disease what's the incidence? ~ 40,000 babies are born each year in the Untied States with congenital heart disease

Congenital heart disease what’s the cause? ~90% of congenital heart disease is thought to be due to ___________ ____________

Congenital heart disease When in gestation does it occur? Development of the heart and great vessels occurs between the 2nd & 9th week of gestation

Congenital heart disease: name the types Lesions with increased pulmonary blood flow Lesions with decreased pulmonary blood flow Mixed circulation defects Obstructive lesions

Lesions with ________ pulmonary blood flow: What are they? ______ septal defect (ASD) ______ ductus arterious (PDA) _________ septal defect (VSD) AV canal defect

Ventricular Septal Defect

Lesions with decreased pulmonary blood flow _________ of _____ ________ atresia _________ atresia Epstein anomaly

Tetralogy of Fallot

Tricuspid Atresia

TET spells – what are they? _____________ spells May occur in any child whose heart defect includes ________ to ________ blood flow and communication between the ventricles

TET spells - what do they look like The infant becomes acutely cyanotic because of sudden ________ in pulmonary blood flow and _______ in _______-to-____ shunting. Spells occur more often in the _______ May be preceded by feeding, crying, or defecation.

TET spells need to be treated ASAP to prevent _______ ______ with resulting brain damage and possible _______

TET spells – what is the management? Place infant in ____- _____ position Employ calm, comforting approach Administer _____% O 2 by face mask Give ________ SQ or IV Begin IV fluid replacement and volume expansion if needed

Mixed Circulation defects What are they? ___________ of the great arteries Total anomalous _________ venous connection Trucus Arterious Hypoplastic ______ Heart Syndrome

Transposition of the great arteries

Truncus Arterious

Obstructive cardiac lesions: What are they ? _________ stenosis Aortic stenosis __________ of the Aorta

Coarctation of the aorta

Pulmonic Stenosis

Cardiac Catherization Pre-Op assessment  accurate ________  assess & mark _____ _______.  baseline ___  explain procedure to child & family

Cardiac catheterization (continued) Post-Op assessment  be aware of most common complications  check pulses ______ cath site  check color and temperature of affected extremity  check vital signs every 15 minutes (per facility policy). * Be sure to check heart rate for a full 60 seconds **_________________________________________ __________________________________

Congestive heart failure Causes of CHF can be classified according to the following changes:  Volume overload*  Pressure overload*  Decreased contractility  High cardiac output demands  * = most common in children in which structural abnormalities result in an increased volume load or increased pressure load on the ventricles.

Therapeutic management of congestive heart failure Two groups of drugs are used to enhance myocardial function in CHF:  Digatalis - improves contractility  ACE inhibitors - reduce the afterload on the heart making it easier for the heart to pump  Diuretics - remove excess fluid

Things to know about giving digoxin to infants & children Always check the dosage with a _______ _______ before giving. Count the ______ pulse Monitor for signs & symptoms of toxicity Know what to do if a dose is missed
