Congenital Defects Flashcards
Complete endocardial cushion defect
Ostium primum defect and VSD
May have attachment of AV valves to IVS
Correction of partial ECD
Pericardial patch
Correction of complete ECD
Dacron patch secured to VSD
Superior portion of patch is attached to common AV valve leaflets
Close ASD with pericardial patch
Four features of tetralogy of Fallot
RV outflow tract obstruction
VSD
Overriding aorta
RV hypertrophy
Fifth feature of pentalogy of Fallot
ASD
Partial endocardial cushion defect
Ostium primum defect
MV and TV annuli fuses, but no interventricular communication (VSD)
Previously known as endocardial cushion defects
Atrioventricular septal defects
Can be partial, intermediate, or complete
Correction of Tetralogy of Fallot
Blalock Taussig shunt (subclavian to PA)
Pulmonary trunk incision (PA valve commisurotmy)
RA incision (muscular outlet septum excised, VSD closed through TV)
Characteristics of tricuspid atresia
Tricuspid valve closed
Small or absent right ventricle (May have VSD)
ASD required for survival
May have PDA
Pulmonary blood flow established through PDA, VSD, or bronchial circulation
Hypoplastic PA
Large LA and LV
Correction of tricuspid atresia
Hemi Fontan and Bidirectional Glenn shunt
Fontan procedure:
- PA to SVC anastomosis
- PA to RA homograft
- ASD closed
- IVC homograft
- Main PA lighted
Most common severe defect
Hypoplastic left heart syndrome
Hypoplastic left heart syndrome
Requires PDA and ASD
Atretic aortic valve
Very small LV and MV
Survive on blood flow though PDA
Two parallel circuits of transposition of the great arteries
LV to PA to lungs to LA
RV to aorta to body to RA
Requires ASD and PDA
Two fixes for TGA
Atrial switch: mustard and senning
Arterial switch: jantene and lacompte
