Q

What is the most common type of congenital heart disease, and which subtype is the most prevalent?

A

Ventricular Septal Defect (VSD) is the most common congenital heart disease.
Within VSD, the membranous subtype, located just below the aortic valve, is the most common, accounting for about 70% of cases.

Q

Why are Outlet subtype VSDs significant, and what complication can they lead to?

A

Outlet subtype VSDs, located in the infundibulum, are significant because they must be repaired to prevent complications. One such complication is the prolapse of the right coronary cusp into the defect.

A

Infracardiac.

70
Q

The most common cause of cyanosis during the first 24 hours?

A

Transposition of the Great Arteries

71
Q

Seen most commonly in infants of diabetic mothrs.

A

TGA

72
Q

Describr the TGA

A

The basic idea is that the aorta arises from the right ventricle and the pulmonary trunk from the left ventricle {ventricularterial discordance).

73
Q

What do you have to find to determine if its right or left ventricle

A

Find the Moderator band (That defines the RV)

74
Q

What does TGA need in order to survive?

A

ASD
VSD (Most common)
PDA

75
Q

What are the two (2) TGA flavors?

A

D type and L type.

76
Q

What type of TOGA is lucky enough to be compatible with life?

A

L-Transposition (LUCKY)

77
Q

What is the classic x ray appearance of d-TGA

A

Egg on a string

78
Q

What procedure is performed to fix the d-TGA

A

Intra-atrial baffle (Mustard or Senning procedure)

79
Q

This occurs from a “double discordance” where the atrium hooks up with the wrong ventricle and the ventricle hooks up with the wrong vessel.

A

l-TGA

80
Q

Describe the d-TGA

A

In D-Transposition, the ductus may be the only connection between the two systems, which would othenwise be separate (and not compatible with life)

81
Q

What can be the only connection between the two systems in d-TGA

A

PDA

82
Q

Describe the l-TGA

A

In L-Transposition of the great vessels - there is an inversion of the ventricles, leading to a “congenital correction. ” No PDA is needed.

83
Q

Identify and described

A

Corrected d-TGA

84
Q

What is the procedure of d-TGA correction

A

“LeCompte Maneuver”

Jatene Arterial Switch

85

What is the most common cyanotic hear disease?

A

Tetralogy of Fallot (TOF)

86
Q

Describe the 4 major findings of TOF

A

(1) VSD, (2) RVOT Obstruction - often from valvular obstruction, (3) Overriding Aorta, (4) RV hypertrophy (develops after birth).

87
Q

The degree of seerity in symtpoms in TOF depends on?

A

How bad the RVOT obstruction is.

88
Q

Whats is the pentalogy of Fallot?

A

(1) VSD,
(2) RVOT Obstruction - often from valvular obstruction,
(3) Overriding Aorta,
(4) RV hypertrophy (develops after birth).
(5) ASD

89
Q

What is the shunt procedure for TOF?

A

Blalock-Taussig shunt

90
Q

What is the most common complication following TOF repair?

A

Pulmonary regurgitation.

91
Q

Describe Truncus Arteriosus

A

Cyanotic anomaly - a single trunk supplying both the pulmonary and systemic circulation, not a separate aorta and pulmonary trunk.

92
Q

What CHD is associated with DiGeorge Syndrome (CATCH 22 gene ;P)

A

Truncus arteriosus.

93
Q

What is the most common associated defect in CoA?

A

Bicuspid Aortic Valve (80%)

94
Q

CoA is associated with what condition?

A

Turners Syndrome (15-20%)

95
Q

What CHD have more berry aneurysms?

A

CoA

96
Q

Rib notching invovles what rib level?

A

4th-8th ribs

97
Q

Differentiate the Infantile vs Adult CoA

A

Infantile:
1. Presents with heart failure within the first week of life.
2. Pre-Ductal (Before the left Subclavian A.)
3. Aortic Arch = Hypoplastic

Adult:
1. Leg Claudication
2. BP differences between arms and legs.
3. Post-Ductal (Distal to left Subclavian A.)
4. Aortic Arch = Normal Diameter
5. Collateral Formation is More Likely

98
Q

What is hypoplastic left heart?

A
  1. Left ventricle and aorta are hypoplastic.
  2. They present with PULMONARY EDEMA.
  3. Must have an ASD or large PFO. They also typically have a large PDA to put blood in their arch.
  4. Strongly associated with aortic coarctation and endocardial fibroelastosis.
99
Q

What is this? Descibe

A

Cor Triatriatum Sinsitrum

Abnormal pulmonary vein draining into the left atrium with an unnecessary fibromuscular membrane that causes a subdivision of the left atrium.

creating the appearance of TRI-TRIUM heart.

100
Q

What CHD can cause an unexplained hypertension in pediatritcs?

A

Cor Triatriatum

101
Q

Why does Cor triatriatum sinistrum cause pulmonary edema?

A

It acts like mitral stenosis.

102
Q

What’s the prognosis of CTS?

A

bad (fatal within 2 years)
