Cardiac Flashcards
stages of hypoplastic left heart surgery
- Norwood with Blalock-Taussig shunt or Sano (modification of Norwood) 2. Bi-directional Glenn 3. Fontan
Norwood
goal: all systemic flow from RV - neoaorta constructed via side-to-side anastomosis of MPA and hypoplastic aorta - Blalock-Taussig shunt to divert some flow to lungs (systemic-pulmonary shunt)
Blalock-Taussig shunt
synthetic graft from Right Subclavian Artery to Right Pulmonary Artery
Sano shunt
Right Ventricle –> Right Pulmonary Artery
Bi-directional Glenn
SVC –> RPA (bi-directional because RPA left open to allow blood to flow into both lungs
Fontan
RA -or- IVC –> PA All blood flow bypasses lungs
MC location for angiosarcoma
Right atrium
Normal MV area
4-6 cm^2
Moderate MV stenosis
1 - 1.5 cm^2
MC locations of cardiac lipomas
atrial septum > right atrium > LV
Blalock-Hanlon procedure
- removal of Atrial septum - used in complete Transposition
normal aortic valve area
> 2.0 cm^2
signs of high risk plaque on CTA
- stenosis > 50% - positive remodeling - napkin ring sign - spotty calcifications - low attenuation plaque
