Q

Dx PDA (CXR, EKG, Echo)

A

Echo = gold standard dx
CXR - normal or cardiomegaly
EKG - LVH, left atrial enlargement

18
Q

Tx PDA

A

IV Indomethacin (dec prostaglandins)

19
Q

Definition coarctation of the aorta

A

Congenital narrowing of thoracic descending aorta
Male: Female 2:1
Usually non-cyanotic

20
Q

Pathophysiology of Coarctation of aorta

A

Inc LV afterload with SNS activity & RAAS activation = HTN, LVH & CHF

21
Q

CP Coarctation of aorta

A

HTN
Bilateral claudication, DOE, syncope
Infants: FTT, poor feeding, shock

22
Q

Murmur of coarctation of aorta

A

Systolic murmur that radiates to the back/scapula/chest

23
Q

PE Findings Coarctation of aorta

A

Systolic murmur that radiates to the back/scapula/chest
Inc BP in UE > LE
Delayed/weak femoral pulses (2/2 dec flow distal to obs in lower extremities)

24
Q

Diagnosis coarctation of aorta

A

CXR:
Rib notching (2/2 inc collateral circulation to intercostal aa)
“3 sign” Narrowed aorta looks like the notch of number 3

EKG: LVH

ANGIOGRAM = GOLD STANDARD FOR DIAGNOSIS

25
Q

MCC Congenital heart disease

A

VSD

26
Q

Tx coarctation of aorta

A

Surgical correction
Balloon angioplasty +/- stent
Prostaglandin preoperatively to reduce sx & improve LE blood flow

27
Q

MC Cyanotic CHD

A

TOF

Cyanotic = key word 
TOF = MC cyanotic CHD
VSD = MC overall
28
Q

4 Features of TOF

A
  1. RVOT obs - pulmonic stenosis
  2. RVH
  3. VSD (large, unrestrictive)
  4. Overriding aorta
29
Q

CP TOF

A

Blue baby syndrome (cyanosis)
Odler: DOE, cyanosis worsens w/ age

“Tet-Spells” - paryoxysms of cyanosis - older children relieve by squatting

30
Q

Murmur a/w TOF

A

Harsh holosystolic murmur heard best at LUSB (like PS)

31
Q

PE Findings TOF

A

Harsh holosystolic murmur at LUSB
RV heave
Digital clubbing

Murmur of VSD = Loud, high-pitched, harsh holosystolic murmur at Left LOWER sternal border

32
Q

Dx TOF

A

CXR: Boot-shaped heart (prominent RV)
EKG: RVH, RAE
Echo: GOLD STANDARD FOR DX

33
Q

Tx TOF

A

Surgical repair performed in first 4-12 mo of life

PGE1 infusion - prevents ductal closure if pt cyanotic prior to surgery

34
Q

Prostaglandin E1 analog & it’s indications

A

Prostaglandin E1 analog = Alprostadil
Indications: Pt w/ cyanotic heart defects where it is beneficial to keep ductus arteriosus open (pulmonary atresia, TOF etc)

35
Q

Definition hypertrophic cardiomyopathy

A

Inherited genetic disorder of inappropriate LV and/or RV hypertrophy (especially septal)

36
Q

Pathophysiology hypertrophic cardiomyopathy

A

Subaortic outflow obs:
Narrowed LVOT 2/2 hypertrophied septum

Diastolic dysfunction:
Stiff ventricular chamber - impaired ventricular relaxation/filling b/c thickened walls lead to smaller LV volume & dec LV filling

37
Q

CP Hypertrophic Cardiomyopathy (5)

A
  1. Dyspnea = MC initial complaint w/ fatigue
  2. Angina pectoris -75%, in setting of normal angiogram
  3. Syncope - including pre-syncope/dizziness (2/2 inadequate CO on exertion)
  4. Sudden cardiac death - esp in adolescent/preadolescent children during extreme exertion - 2/2 ventricular fibrillation - DO CPR!!!
38
Q

Murmur of hypertrophic cardiomyopathy

A

Harsh systolic crescendo-decrescendo murmur best heard at LLSB (similar to AS)

39
Q

Murmur of hypertrophic cardiomyopathy:
Accentuated with _______
Diminished with ________

A

Accentuated with decreased venous return (valsalva, standing) - may have loud S4, mitral regurg, S3 or pulsus bisferiens

Murmur diminished with increased venous return (squatting, lying supine) b/c increased LV volume preserves outflow (inc fluid pushes septum out of way & dec SAM of mitral valve)

40
Q

Dx Studies hypertrophic cardiomyopathy

A

Echo - asymmetrical wall thickness > 15mm, systolic anterior motion of mitral valve, small LV chamber size, dynamic outflow obstruction +/- mitral regurg

EKG: LVH, atrial enlargement, anterolateral & inferior pseudo q waves

CXR: Cardiomegaly

41
Q

Tx hypertrophic cardiomyopathy

A

Focus: Early detection, medical management, surgical and/or ICD placement. Counseling to avoid dehydration & extreme exertion and exercise is VERY IMPORTANT

  1. Medical - BB = 1st line medical tx , also CCB, disopyramiide (negative inotropes that inc ventricular diastolic filling time)
  2. Surgical - myomectomy - in pt w/ severe , refractory sx despite medical management
  3. Alcohol septal ablation - alternative to surgical management w/ good outcomes
