Cardiac COPY 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
napkin ring sign (high risk plaque)
thebesian valve
(@ junction of coronary sinus and RA)
what marks junction of coronary sinus and great cardiac vein?
valve of Vieussens
what is remnant of left SVC?
ligament of Marshall
what is location of ligament of Marshall?
left atrium and left superior pulmonary vein
LV papillary muscles
anterior and posterior
coronary artery anomalies are associated with
- Trisomy 18
- Klinefelter’s
- Bland-White-Garland
situs inversus incompletus
levocardia + right-sided stomach
situs inversus totalis
dextrocardia + right-sided stomach
Kartagener’s triad
- sinusitis
- bronchiectasis
- situs inversus
