greater RV compliance determines flow and RV eventually overlaods leading to RVE/arrythmia. May have paradoxical embolus. Surgical repair.
more severe with larger VSD and smaller murmur. L-R shunt decreases CO-> CHF by 6 wks and damages aorta. If large VSD, surgery. Otherwise cath is option
common down's syndrome complication due to endocardial defect. surgery
Tetralogy of Fallot
right ventricle outflow obstructed w/ harsh ejection mumur. Surgery shunts aortic blood to lungs. PGE temporarily helps
decreased RV filling worsens obstruction causing cyanosis. + feedback so must increase SVR.
Transposition of great arteries
No systemic O2 perfusion. Prior to surgery. Open DA (PGE1) and FO(w/ balloon) and use heart lung machine. Must surgically switch arteries and coronaries prior to LVH
late onset VSD and PHTN. Increased afterload causes R->L shunt and LV dilation. Treat with lung transplant
absent TV req. VSD to supply RV. Keep DA open with PGE1, then surgically attach vena cava directly to pulmonary artery
Hypoplastic Left Heart
another that DA closure ppt. req three surgeries to make aorta fro p. art. and shunts blood to pulm art so heart only O2 blood. ASD must remain open
One artery from heart. Close VSD so LV supplies artery->aorta. Create p. art that will have to be replaced with growth. Had one valve so must function well.
Total anomalous venous return
P. veins do not empty into LA so blood mixes through ASD. Surgery can attach p. veins to l. art and works pretty good.
