2 cardiology Flashcards
Functional closure of Foramen ovale
3mos
Functional closure of ductus arteriosus
10-15 HOL
MC cardiac malformation
VSD
Gooseneck deformity in 2d echo
Endocardial cushion defect
CI to closure of VSD
Severe pulmo vascular dse
Physiologic closure of PDA
10-15hrs
Anatomic closure of PDA
2-3wks
MC form of ASD
ostium secundum
MC lesions resulting in increase pressure load
valvular PS
Aortic Stenosis
Coarctation of the aorta
anomalous venous drain to IVC with pulmo sequestration & anomalous arterial supply
Partial Anomalous Pulmonary Venous Return
MC cardiac malformation
VSD
MC type of VSD
membranous type
loud, harsh or blowing holosystolic murmur @ lower left sternal border with a thrill
VSD
grade 2-3 systolic ejection murmur (left mid & upper sternal border)
ASD
criteria for surgical closure of VSD
- any age w/ LARGE defect, uncontrolled by meds
- 6-12 mos old w/ large defect & pulmo hypertension
- > 24 mos old w/ Qp:Qs >2:1
- supracristal VSD
effects of large PDA
- inc risk for pulmo vascular dse
- wide pulse pressure
- heart failure & growth retardation
continuous machinery murmur @ left infraclavicular area with bounding peripheral pulse
PDA
reason for surgical or catheter closure in PDA
small PDA: prevent bacterial enderitis
large PDA: treat heart failure, prevent pulmo vasuclar dse
left to right shunt lesions (Acyanotic)
