How do you dx ASD?
Echo

VSD
Dx of VSD?
Echo
MC site of VSD?
High in membranous septum
How do you treat a typical VSD?
Surgical closure
What type of VSD produces a murmur but otherwise few symptoms?
Small, restrictive VSD low in the muscular septum
2-3 mo old baby w/ small, restrictive VSD low in the muscular septum. Tx?
Obs- most close spontaneously w/in first 2-3 yr of life.
3 day old baby w/ bounding peripheral pulses and a continuous “machinery-like” murmur. Dx?
PDA
Dx of PDA?
Echo
Treatment of PDA in a preemie who hasn’t gone into CHF?
Close w/ indomethacin
Tx of PDA in full-term babies, preemies w/ CHF, and preemies who don’t close w/ indomethacin? 2 options
Surgical closure or embolization w/ coils
What type of shunt p/w murmurs, diminished vascular markings in the lung, and cyanosis?
R-to-L
Which R-to-L shunt is cyanotic but kills by overloading the pulmonary circulation?
Truncus arteriosus
5 yo who is small for their age w/ bluish lips and fingertips, clubbing, and cyanotic spells relieved by squatting. Dx?
ToF
Young child w/ systolic ejection murmur in left 3rd ICS, CXR showing decreased vascular markings and a small heart, and EKG signs of RVH. Dx?
ToF
Dx of ToF?
Echo
Tx of ToF?
Surgery
2 day old cyanotic baby who is SICK. Dx?
Transposition of great vessels
Transposition of great vessels- Dx?
Echo
Transposition of great vessels- how do babies stay alive until Dx?
Concurrent ASD/VSD/PDA (1 or more)
Transposition of great vessels- Tx?
Surgery
Older person w/ angina, exertional syncope, and a harsh midsystolic murmur @ R 2nd ICS and the left sternal border. Dx?
Aortic stenosis
Aortic stenosis. Dx?
Echo
Treatment of symptomatic aortic stenosis?
Valve replacement
Pt w/ wide pulse P, blowing high-pitched diastolic murmur best heard @ R 2nd ICS and left lower sternal border during full expiration. Dx?
Chronic aortic insufficiency
In general, when do you do valve replacement in chronic aortic insufficiency?
Any evidence of LV dilitation on echo
Young IVDU w/ sudden onset of CHF and new loud diastolic murmur at 2nd R ICS. Dx?
Acute aortic insufficiency
How do you treat acute aortic insufficiency?
Emergent valve replacement + long-term Abx
Patient w/ DOE, orthopnea, PND, cough, hemoptysis, and low-pitched rumbling diastolic apical murmur who is now becoming cachectic and developing Afib. Dx?
Mitral stenosis
Dx of mitral stenosis?
Echo
Tx of symptomatic mitral stenosis?
Valve repair (surgical comissurotomy or balloon valvuloplasty)
DOE, orthopnea, Afib, and apical high-pitched holosystolic murmur that radiates to axilla and back. Dx?
Mitral regurg
MCC of mitral regurg?
MVP
Tx of symptomatic mitral regurg?
Annuloplasty
Middle-aged sedentary male smoker w/ T2DM, HLD, and FHx CAD who p/w angina. Dx?
CAD
What % stenosis is criteria for intervention in CAD?
70%. And don’t forget you also need good distal vessel!
Triple vessel CAD. Tx?
CABG
Normal CO and CI?
CO: 5 L/min
CI: 3
If post-op heart surgery patient has considerably decreased CO or CI, what should you measure next?
PCWP
Post-op heart surgery patient has considerably decreased CO or CI. PCWP is low (0-3). What does this patient need?
IVF!
Post-op heart surgery patient has considerably decreased CO or CI. PCWP is high (20 or greater). What’s likely wrong?
Ventricular failure
Patient p/w DOE, hepatomegaly, ascites. Square root sign + equalization of pressures on cath. Dx?
Chronic constrictive pericarditis
Tx of chronic constrictive pericarditis?
Surgery
Coin lesion on CXR. Next best step?
Compare to older xray
Coin lesion on CXR and either no older CXR for comparison or lesion wasn’t present on old CXR. What 2 tests should you order?
Sputum cytology and CT chest and abdomen
Dx of central lung cancer? Peripheral?
Central: bronch w/ bx
Periph: percutaneous bx
Strongly suspect lung cancer but can’t get dx w/ bronch bx or percutaneous bx. What else could you do?
VATS and wedge resection
If pneumonectomy is required for tx of lung cancer, and you’re worried about post-op lung fxn (COPDer, SOB, etc), what tests should you get?
PFTs, V/Q scan
What residual FEV1 is req to proceed w/ pneumonectomy?
800 mL
How do you determine the residual FEV1?
Measure FEV1, then get a V/Q scan to determine fraction of FEV1 coming from each lung. Calculate what would remain after pneumonectomy.
