HemodynamicsPreload-• Venous return during diastole. • Volume of blood = Hydration

statusAfterload-• Arterial flow during systole.• L Ventricular pressure to open

Aortic valve.Cardiac Output = HR x SV• Heart Rate X Stroke Volume

Page 3: CardiacCardiac Elisa A. Mancuso RNC, MS, FNS Professor of Nursing.

Murmurs

Abnormal heart sounds • Improper closing or opening of valves• 80% of murmurs in kids are innocent • Close proximity of heart to chest wall • Stills Murmur –

– Blood rushing out of aorta

• Anemia • Fever

STEVEN L. GARGANO

Fetal CirculationOxygenated blood → Inferior Vena Cava (IVC)

IVC → RA → FO → LA → LV → Aorta → Head & Arms– ↑↑ pressure in RA → Foramen Ovale (FO)– Bypasses the lungs and blood shunted to LA

↓ Blood returned → Superior Vena Cava (SVC)

SVC → RA → RV → PA→ DA →Aorta → Lower Body & LegsDuctus Arteriosus (DA)– Bypasses the lungs (↑↑ Pressure) – Only small portion of blood goes to pulmonary

system– Blood gets re-oxygenated via placenta

Ductus Venosis

– Bypasses the liver and shunts blood to IVC

Page 5: CardiacCardiac Elisa A. Mancuso RNC, MS, FNS Professor of Nursing.

Fetal to Neonatal Circulation

At birth lungs expand:• ↑ O2 causes pulmonary vasodilation• ↓ Pulmonary pressure (resistance)• ↑ Systemic pressure (resistance)

– LA pressure > RA pressure– Foramen Ovale closes within 1st hour of life

• ↑O2 ↓Prostaglandins (from Placenta)– Ductus Arteriosus closes within 10-

24hours.– Permanent closure by 3-4 weeks.

– PDA = Patent Ductus Arteriosus • In some cases can stay open for 3

months

Page 6: CardiacCardiac Elisa A. Mancuso RNC, MS, FNS Professor of Nursing.

Neonatal Circulation

• Blood flows from higher to lower pressure

• Systemic Pressure > Pulmonary Pressure L side > R side Blood flows from L → R side

Page 7: CardiacCardiac Elisa A. Mancuso RNC, MS, FNS Professor of Nursing.

Acyanotic Defects

• L →R side shunt of oxygenated blood

• ↑ Pulmonary blood flow • Pulmonary congestion• Heart is ineffective pump• Children prone to CHF• Prophylactic administration of

antibiotics needed

Page 8: CardiacCardiac Elisa A. Mancuso RNC, MS, FNS Professor of Nursing.

Patent Ductus Arteriosus (PDA)

Opening between the pulmonary artery (PA) and Aorta

Oxygenated blood shunted from Aorta →→PA– ↑↑ Systemic resistance

• Blood shunted to LA → LV → PA

• ↑↑ Pulmonary Congestion

• ↑↑ Back up to LA & LV

• LV Hypertrophy

Page 9: CardiacCardiac Elisa A. Mancuso RNC, MS, FNS Professor of Nursing.

PDA Clinical signs • Soft - harsh systolic newborn

murmur • Machinery type systolic and

diastolic murmur in older children• ↑ RR & moist Breath sounds• Bounding pulses • ↑ HR• Widened pulse pressure

– Large difference between the systolic – and diastolic pressure

Page 10: CardiacCardiac Elisa A. Mancuso RNC, MS, FNS Professor of Nursing.

Therapy • Indomethacin (indocin)

– Prostaglandin inhibitor promotes vasoconstriction and closure of PDA

– 3 Dose maximum q 12 hours

• Ligation of Ductus Arteriosus– Close connection to prevent return

of oxygenated blood to lungs– No open heart surgery –

Page 11: CardiacCardiac Elisa A. Mancuso RNC, MS, FNS Professor of Nursing.

Atrial Septal Defect (ASD)

Abnormal opening between the RA & LA • Blood flows from ↑↑press LA to ↓↓press RA• ↑↑ blood volume to right side of heart

– Leads to RA and RV hypertrophy • ↑↑ blood volume to lungs

– Pulmonary Congestion• DOE/ CHF symptoms• Crescendo/decrescendo systolic • ejection murmur

Page 12: CardiacCardiac Elisa A. Mancuso RNC, MS, FNS Professor of Nursing.

ASD Therapy• ASO (Amplatzer Septal

Occluder) – via cardiac cath

• Medications for CHF• Open heart surgery and

bypass, performed before school age

• Dacron patch• Low mortality rate

Page 13: CardiacCardiac Elisa A. Mancuso RNC, MS, FNS Professor of Nursing.

Ventricular Septal Defect (VSD)

Abnormal opening between RV and LV

• ↑↑O2 blood from LV to RV• ↑↑ blood to RV = RV

hypertrophy• ↑↑ pulmonary flow • ↓↓ systemic flow

• Spontaneous closure in 20%-60% within first year of life.

Page 14: CardiacCardiac Elisa A. Mancuso RNC, MS, FNS Professor of Nursing.

VSD Clinical signs • CHF = ↓↓CO, ↑HR, ↑RR, scalp

sweating, – ↑ weight gain, irritability

• Pulmonary edema• DOE, fatigue, ↓↓ PO intake• ↓↓Aorta Blood Flow

– ↓↓ femoral and brachial pulses– ↓↓ BP x 4

• Harsh holosystolic murmur with thrill

Therapy same as ASD

Page 15: CardiacCardiac Elisa A. Mancuso RNC, MS, FNS Professor of Nursing.

Pulmonic Stenosis (PS)

Narrowing of the pulmonary valve

• ↑↑ PA pressure/resistance

• ↓↓ Pulmonary Blood Flow

• Blood backs up into RV RV Hypertrophy

Page 16: CardiacCardiac Elisa A. Mancuso RNC, MS, FNS Professor of Nursing.

Clinical Signs & Therapy

• Depends on size of stenosis• Pale, lethargic, slow feeder• Systolic ejection murmur• EKG and CXR show RV Hypertrophy

Therapy• Pulmonary Valvotomy

– Angioplasty – Enlarges ↑ pulmonic valve

opening

Page 17: CardiacCardiac Elisa A. Mancuso RNC, MS, FNS Professor of Nursing.

Aortic Valvular Stenosis

Narrowing of aortic valve• ↑↑ Resistance to blood flow from LV

– causing LV Hypertrophy

• ↑↑ back-up of blood in pulmonary system – ↑↑ Pulmonary congestion

• ↓↓ blood via aorta ↓↓Systemic perfusion = ↓↓

CO

Page 18: CardiacCardiac Elisa A. Mancuso RNC, MS, FNS Professor of Nursing.

Clinical• Faint peripheral pulses RT ↓↓ CO• ↓↓ pulse pressure• Chest pain RT myocardial ischemia• Systolic ejection murmurTherapy• Commissurotomy

– Enlarge aortic valve opening via angioplasty.

• Additional surgery may be needed

• later.

Page 19: CardiacCardiac Elisa A. Mancuso RNC, MS, FNS Professor of Nursing.

Coarctation of the Aorta

• Narrowing of the aorta right after arch

• ↑↑Pressure proximal to narrowing – ↑↑ BP upper body, arms & head– Bounding pulses & warm, ruddy skin– JVD

• ↓↓Pressure distal to narrowing – ↓↓ BP lower body & legs– Weak pulses & cool, pale skin

• Difference of 20mm for systolic BP

Page 20: CardiacCardiac Elisa A. Mancuso RNC, MS, FNS Professor of Nursing.

Clinical signs• ↑↑ BP in arms ↓↓ BP legs• Weak or Absent femoral pulses• Headache, blurred vision and nose bleeds• ↑↑risk for stroke• Older kids leg pain on exertion RT ↓

bloodTherapy• Prostaglandin E – keep PDA open• Surgery

– Resect coarcted portion and reanastomosis

Page 21: CardiacCardiac Elisa A. Mancuso RNC, MS, FNS Professor of Nursing.

Cyanotic defects• Unoxygenated blood enters

systemic system • “Right to Left shunt” (R→ L)• Blood is shunted from venous to

arterial• ↑↑ CHF and hypoxic episodes

Now classified as: ↓↓ Pulmonary blood flow or Mixed blood flow defects

Page 22: CardiacCardiac Elisa A. Mancuso RNC, MS, FNS Professor of Nursing.

Transposition of Great Vessels (TGA)

• Two separate circulations!

• Aorta arises from RV– Unoxygenated blood enters aorta

→Systemic

• Pulmonary artery (PA) arises from LV– Oxygenated blood enters PA → recycled

lungs → Pulmonary veins → LA

No Oxygenated blood in systemic circulation!

Page 23: CardiacCardiac Elisa A. Mancuso RNC, MS, FNS Professor of Nursing.

TGA CLINICAL SIGNSDepends on type and size of

associated defects• Severely cyanotic at birth

– minimal communication between 2 systems

• Large septal defects or PDA – Less cyanotic but may have CHF

symptoms•↑↑ HR, ↑↑ RR and cardiomegaly•Fatigue when feeding•↓↓ Intake •↓↓Output = Edema

Page 24: CardiacCardiac Elisa A. Mancuso RNC, MS, FNS Professor of Nursing.

THERAPYProstaglandin E1 (Prostin VR or Alprostadil) • Vasodilator • Relaxes smooth muscle of ductus arteriosus • Keeps PDA open • Provides mixing of oxygenated and

deoxygenated blood to systemic circulation.

“Rashkind procedure”• Cardiac cath to create ASD• Maintains mixing of blood• Arterial switch procedure usually

performed • in first few weeks of life

Page 25: CardiacCardiac Elisa A. Mancuso RNC, MS, FNS Professor of Nursing.

Tetralogy of FallotInvolves four cardiac defects• VSD

– Blood shunted RV→ LV• Pulmonary Stenosis

– ↓↓ blood to PA• Overriding Aorta

– Sits over VSD• RV Hypertrophy

achieved?

Page 41: CardiacCardiac Elisa A. Mancuso RNC, MS, FNS Professor of Nursing.

Respiratory Infections

↑↑Risk– Pulmonary vascular congestion– Bacterial invasion and growth

•RT stasis of secretions (prophylaxis meds)

Therapy– Meds

•Bronchodilators•Steroids

– PD & C – O2

Page 42: CardiacCardiac Elisa A. Mancuso RNC, MS, FNS Professor of Nursing.

Compensatory Mechanisms

• Cardiomegaly– ↑ pumping action of heart = ↑ SV– ↑ use of cardiac muscle = ↑ O2 availability – ↑ size = hypertrophy

• Tachycardia >160 in infant– ↑ rate = ↑ CO– ↑ O2 to tissues and vital organs

• Polycythemia– ↑ production of RBC’s– ↑ availability of O2 to tissues – ↑ viscosity of blood – ↓↓ flow, sluggish– ↓↓ decreased peripheral circulation – High risk for CVA

• Tachypnea > 60 in infants– ↑↑ RR = ↑↑ O2

Page 43: CardiacCardiac Elisa A. Mancuso RNC, MS, FNS Professor of Nursing.

Compensatory Posturing • ↑↑ O2 to vital organs by ↓↓ workload of heart

– Less area for blood to flow = ↓↓ venous return

– “TET Spells”

• Infants– May be flaccid with extremities extended – Knee chest position (infant seat)

• Preschool– Squatting position

•occludes femoral vein = ↓↓ venous return ↓↓ workload on heart ↑↑O2 sat & ↑↑ blood to vital organs
