1-100 Flashcards
what makes an aortic dissection “Complicated”
Complicated dissection is those with:
- persistent pain
- thoracoabdominal mal perfusion
- impending rupture
sizing of the graft for a valve-sparing root
- Estimated annulus
- Dacron graft size
Aortic annulus ~ 2/3 cusps height x 2
Dacron graft ~ 2/3 cusps height x 2 + LVOT thickness
DeBakey type 1 aneurysm
Ascending and descending aorta
Signs of mitral stenosis
- Low volume pulse pressure
- Irregular pulse
- Tapping non-displaced apex beat
- Loud S1 heart sound
- Opening snap Mid diastolic rumbling heart loudest at the apex
- Pulmonary HTN
- Mitral facies : Rosy cheeks while the rest of the face is cyanotic
- Central cyanosis
- Loud P2 heart sound
- TR – pan systolic murmur at right sternal edge
- Pulmonary Regurgitation: Grahm Steel early systolic murmur on inspiration
Social history questions for aortic dissection
physical exam
Query the use of amphetamines or coccaine
Physical:
Skeletal to diagnose CT disease
Vascular exam should be documented
Medical treatment of a type B dissection
a. Beta - blocker ( esmolol or labetolol)
b. vasodilator (nipride)
what territory does ECG lead I represent
anterolateral
Severe mitral regurgitation in an asymptomatic patient direction
of treatment
- if LVEF > 60, LVESD < 40 and liklihood of repair > 95% with expected mortality < 1% –> Repair
- if new onset afib or PASP > 50 and liklihood of repair > 95% and expected mortality < 1% –> Repair
- if LVEF 30-60% or LVESD > 40 –>“mitral surgery”
Per Boling:
LVEF < 60%, PAP > 50, LVESD > 40, AF
If > 95% repair, <1%, mortality
MVA for Moderate MS
MS (mitral valve area 1.6 cm2 to 2.0 cm2)
the direction of the jet with a restricted leaflet
jet will be toward the restricted leaflet
Ghent criteria
Minor Skeletal Criteria
- Pectus excavatum of moderate severity
- Joint hypermobility
- Highly arched palate with crowding of teeth
- Facial appearance:
- dolichocephaly
- malar hypoplasia
- enophthalmos
- retrognathia
- down-slating palpebral fissures
Low Risk Pulmonary Embolism
Embolism without the presence of :
- shock
- hypotension
- RV dysfunction
- Myocardial injury
Diagnostic criteria for STEMI
Angina sx for > 20 min
with
ST elevation > 1mm in 2 contigous leads
or
LBBB
Method of selecting a tricuspid ring size
- Using a sizer:
septal leaflet and the surface area of leaflet tissue from the anterior pap muscle
- Approximately
30-32 for a female
32-34 for a male
Reccomendation
Mitral stenosis patient
symptomatic
MVA < 1.5cm2
Wilkins < 8
No LA thrombus
No MR
Class 1: PMBC
Anteroseptal ECG leads
V1 and V2
IIb/IIIa inhibitors
when should they be discontinued
- Eptifibatide (integrillin) - IIb/IIIa Inhibitor - 2-4 hr
- Tirofiban ( Aggrastat) - IIb/IIIa inhibitor -2 -4 hours
- Abciximab (Repro) - IIb/IIIa inhibitor -12 hours
EAT !
Crawford Type IV aneurysm
Extends from the diaphragm to below the renal arteries
what territory does V6 represent?
anterolateral
Ghent Criteria
Pulmonary minor criteria
Spontaneous PTx
Apical Blebs
Type B aortic dissection -
Medical vs Surgical management
what is the rate of surgical reintervention
Equivalent
Fondaparinux trade name
Arixtra
Ghent criteria
minor skin criteria
- Strech marks not associated with weight changes
- Recurrent incisional hernia
Ghent Criteria:
Major family history Criteria
- Having a first-degree relative (parent, child, or sibling) who meets these diagnostic criteria independently
- Presence of a mutation in FBN1 known to cause the Marfan syndrome
- Presence of a haplotype around FBN1, inherited by descent, known to be associated with unequivocally diagnosed Marfan syndrome in the family
Posterior medial papillary muscle
blood supply
PM pap muscle is more vulnerable because of its single blood supply:
RCA for right dominant
cx for left dominant
DeBakey IIIa aneurysm
Confined to the thoracic descending aorta alone
“theme” of fibroelastic defficiency mitral repair
No resection or limited resection
which ECG lead is the ground?
Right Leg
Ghent Criteria
Minor CV Criteria
- Mitral valve prolapse with or without mitral valve regurgitation
- Dilatation of the main pulmonary artery, in the absence of valvular or peripheral pulmonic stenosis or any other obvious cause in patients age < 40 years
- Calcification of the mitral annulus in patients age < 40 years
- Dilatation of dissection of the descending thoracic or abdominal aorta in patients age < 50 years
“theme” to Barlow’s repair
Barlow’s - remove tissue
Tissue dissection and leaflet displacement
General criteria for Marfan’s Diagnosis by Ghent
Positive family history
- at least 2 systems (skeletal, cardiovascular, ocular)
- and the presence of at least 1 major criterion (eg, ascending aortic aneurysm, ectopia lentis)
negative family history / unknown__,
major criteria in 2 systems and have involvement of at least 1 other system (skeletal, cardiovascular, ocular).
Ghent Criteria
Major Skeletal Diagnostic Criteria
Presence of at least 4 :
- Pectus carinatum
- Pectus excavatum requiring surgery
- Reduced upper-to-lower segment ratio or arm span-to-height ratio greater than 1.05
- Wrist and thumb signs
- Scoliosis > 20 degrees or spondylolisthesis
- reduced extensions at the elbows (< 170 degrees) Medial displacement of the medial malleolus causing pes planus
- Protrusio acetabulare of any degree (ascertained on radiographs) (femoral head is medial to the ileoischeal line)
The goal of a medical therapy for a type B dissection
Reduction of the Systolic bp
Reduction of the mean bp
Reduction of the dp/pt
how long should a BMS be on plavix

What is the Crawford Extent:
Descending aorta from near the left subclavian to the abdominal vessels but not the renal arteries
Type I
Anterio apical ECG leads
V3 - V4
In repairing a descending aneurysm
what should be done with intercostal arteries above T7?
Why?
Oversew
Eliminate steal of blood from the spinal cord
ECG of PE
Lead 3 findings
- q-wave
- inverted t-wave
Factors which make a patient more susceptible to recurrent MR
- larger MV annular diameter (>3.7cm)
- High tethering area
- greater MR severity (3.5+)
