8 Echocardiogram , #18 1) Large PMOE VSD (9.6mm) with left-to-right dominant bidirectional shung 2) Large secundum ASD (8.8 x 7.4 mm) with left-to-right shunt 3) dilated RA & RV 4) no PDA, no CoA 그래서 그라목손의 acute intoxication impression 하에 Page  8

9 Initial Lab 그래서 그라목손의 acute intoxication impression 하에 Page  9

10 Problem List #1. Preterm AGA #2. Low birth weight infant
#3. Syphilis mother's baby #4. Abnormal echocardiographic finding including VSD 그래서 그라목손의 acute intoxication impression 하에 Page  10

11 Assessment #1, #2, #4 VSD (SA, small to moderate)
그래서 그라목손의 acute intoxication impression 하에 Page  11

12 Plan VSD closure with bovine pericardium ASD primary closure Page  12

13 Operation Operation 수술 후 진단명 VSD closure with bovine pericardium
ASD primary closure 수술 후 진단명 VSD (PMOE, large) ASD (secundum, large) 환자 입원 후 높은 사망가능성 및 예후가 안 좋음을 설명하였고, hydration 과 dexamethasone 그리고 hemoperfusion을 시행해주었습니다. 기본 랩들과 chest AP를 찍었스빈다. Page  13

15 Hospital Course – POD #1 응급실 입원 1일 째, 다른 문제는 없었으나 cost문제로 결국 타 병원으로 이송되었습니다. Page  15

16 Ventricular Septal Defect 2007313075 Son Eui Young
Disease Review 디지즈 리뷰에서는 그라목손이 속한 쿼터너리 나이트로겐 컴파운드 계열의 drug intoxication에 대해서 말씀드리겠습니다. Ventricular Septal Defect Son Eui Young 16

17 Introduction 1 in 1000 live births 선천성 심질환 중 가장 흔하다. (단독으로는 25%)
50% associated with other congenital malformations First described by Roger in 1879, hence small VSDs are also known as the ‘maladie de Roger’. First VSD closed under direct vision by Lillehei in 1955 태어나는 아기 1000명중 1명 꼴로 발생하는, 선천성심질환 중 가장 흔한 병입니다. 단독으로는 25%정도이며, VSD중 절반은 다른 기형을 동반합니다. 라거~라는 사람이 처음 describe 하였고, 릴레이~라는 사람이 처음으로 VSD를 닫았다고 합니다. Page  17

18 Anatomic Classification of VSD
Perimembranous: 80% Subarterial: 14% Muscular VSD : 10% Figure 117–4 Classification of ventricular septal defects (VSDs):

19 Commonly Associated Defects
Patent ductus arteriosus (PDA) :25% Diagnostic difficulties:preop.echo, TEE etc should be ligated or clipped Coarctation or Aorta : 10% Augmented L-R shunt left ventricular outflow tract obstruction(Congenital valvar or subvalvar aortic stenosis): 4% large atrial septal defects (ASDs), right ventricular outflow tract obstruction, vascular ring, and persistent left superior vena cava.

20 Pathophysiology Shunt Direction and Magnitude Small size
depend on the size of the defect and the pressure gradient Qp/Qs Small size RV의 수축기압을 의미있게 증가시키지 못하는 작은 결손 폐동맥혈류 증가가 심하지 않음 (Qp/Qs < 1.75) 폐동맥고혈압 없음 Large size : 결손 크기가 aortic valve ring 보다 클 때 폐혈관저항 증가 (Qp/Qs > 2) 우심실과 좌심실간의 압력차가 소실되거나 역전되어 L-R shunt와 R-L shunt 가 같이 생김 청색증, 객혈, 심부전증 등이 나타나 사망할 수 있음 병태생리는 크기에 따라 결정됩니다.

22 Complication Growth failure
Congestive heart failure (left heart failure) Pulmonary vascular disease :as Eisenmenger syndrome or complex Severe illness with viral or bacterial pneumonia Infective endocarditis Aortic regurgitation Stenosis in the right ventricular outflow tract Discrete fibrous subaortic stenosis Acquired left ventricular outflow tract obstruction Aneurysm of the ventricular septum Paradoxical emboli Sudden death Heart block secondary to intracardiac repair Impaired left ventricular function in some patients Increase in weight following VSD closure

23 Diagnostic work-up Symptoms
tachypnea, growth failure, profuse sweating during feeding, a bulging precordium, a pansystolic murmur, an enlarged liver, and thready pulses the physical examination, chest radiograph, and electrocardiogram (ECG)

24 VSD Natural Course Spontaneous closure or decrease of size
Perimembranous or muscular type Aggressive medical management cf. Malalignment type, SA, MO, Endocardial cushion type Usually within 6-12 Mo of age

25 VSD Natural Course Eisenmenger or Severe PHT
Usually after 1 yr of age Contraindications for op d/t PHT - PVR > 8-10 Wood unit - No response to pulmonary vasodilators such as O2 or nitric oxide - Mainly R-L shunt or no L-R shunt through VSD

26 VSD Natural Course AV Deformity
Mainly subarterial type Some of PM type MO VSD Increased incidence of infective endocarditis if there is AR

27 VSD Natural Course Subaortic stenosis
Usually discrete membrane type Occasionally tunnel type Op indications AV deformity PG > mm Hg

28 Treatment of VSD : Indications
Approximately 30% of infants surgery within the first year of life Significant shunt Medically uncontrolled CHF PA pressure > 1/2 of systemic artery pressure Shunt amount; Qp/Qs > 1.5 or 1.7 Other problems DCRV, Subaortic stenosis, AV deformity Consider natural course, patient’s age

29 Treatment of VSD : depends on size
Large VSD < 3 months – CHF, failure to thrive Elective repair at 6-12 months (PVR < 8.0 units) Small VSD (Qp:Qs<2:1) Endocarditis Cardiac Enlargement Any Aortic Incompetence Subarterial (supracristal) VSD - any size, operate early
