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

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

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

Neonatal Circulation

• Blood flows from higher to lower pressure

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

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

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

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

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 –

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

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

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.

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

Pulmonic Stenosis (PS)

Narrowing of the pulmonary valve

• ↑↑ PA pressure/resistance

• ↓↓ Pulmonary Blood Flow

• Blood backs up into RV RV Hypertrophy

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

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

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.

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

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

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

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!

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

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

Tetralogy of FallotInvolves four cardiac defects• VSD

– Blood shunted RV→ LV• Pulmonary Stenosis

– ↓↓ blood to PA• Overriding Aorta

– Sits over VSD• RV Hypertrophy

– ↑ pressure from stenosis

Clinical signs of Tetralogy

• First cry hypoxic and cyanotic

• ↑↑ Activity = ↑↑ Hypoxia and ↑↑ Cyanosis– Pulse oximeter in low 70’s

• ↑↑ Pulmonary stenosis = ↑↑ Cyanosis• ↑↑ HR, ↑↑ RR• Tire easily can’t finish feedings = ↓↓ Intake

• Chronic O2 deficit → Polycythemia

– ↑↑ # RBC’s to supply 02 to body – ↑↑ Risk of CVA or embolism with

dehydration

Clinical Manifestations

• “Tet” Spells – ↑↑ Activity or ↑↑ Crying = ↓↓ blood flow to

brain– ↑↑ hypoxia, cyanosis and fainting

• Squatting – compensatory action– Knee chest position– ↓↓femoral blood flow ↑↑blood flow upper

body

• Clubbed fingers• Mental retardation

shunt btwn PA and Aorta2) Glenn @ 6 month to a year

shunt from SVC to PA to lungs 3) Fontan @ 2-3 years shunt from IVC to PA to lungs No more mixing of blood

Truncus Arteriosus

• One common artery arises from LV & RV.

• Overrides a large VSD• No separate PA or Aorta• Unoxygenated blood enters systemic

circulation• ↑↑ blood volume flows to lungs • ↑↑ pulmonary blood flow• ↑↑ pulmonary edema ↑↑ CHF

•ETOH may be associated with FAS and Tetralogy of Fallot

Physical ExamThoracic ExamCardiac Sounds• √ Location of PMI (5th LICS MCL)• √ Rate• √ Rhythm• √ Murmurs

– location, intensity and where in cardiac & respiratory cycles

• √ visible pulsation on thorax• √ JVDBreath Sounds

– √ Rate, rhythm– √ Dyspnea and Grunting (keep alveoli

open)– √ Adventitious sounds– Moist- Pulmonary congestion or CHF

COLOR

• √ Mucous membranes– Lips, conjunctiva and nail beds.

• √ Cyanosis – @ rest or with activity

• √ clubbed fingers

• Flushed cheeks = Polycythemia – KEEP INFANTS HYDRATED! – WHY?

Pulses

• Palpate bilaterally • Compare upper and lower

extremities – Absent or ↡femoral pulses in

Coarctation

• √ Rate/Rhythm/strength (0-+4)• √ BP all four extremities

– Widened pulse pressure in PDA – ↑↑ BP upper extremities in

Coarctation.

Nutritional Status√ Intake

available O2

√ HT, WT and HC√ Activity level-tires easily?• Developmental tasks

achieved?

Respiratory Infections

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

•RT stasis of secretions (prophylaxis meds)

Therapy– Meds

•Bronchodilators•Steroids

– PD & C – O2

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

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

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