ASD
- Things that cause increased blood volume?
- Things that cause decreased blood volume?
- What happens to murmurs w/ increased blood volume?

What happens to murmurs w/ expiration? Why?
- All L sided murmurs increase except MVP and HOCM (these decrease)
- Increased flow to the L side of the heart
What happen to murmurs during inspiration? why?
- increase all R sided murmurs

What positions cause decreased volume return to the heart?
Standing, Valsalva
Handgrip and phenylephrine have what effect on afterload?
Increases which murmurs?
- increases afterload,
- increases flow to murmurs that flow backward (AR, MR, VSD)
Handgrip or phenylephrine has what effect on MR, MVP, and HOCM?
- Handgrip and phenylephrine increases afterload
Decreases HOCM (less obstruction of LVOT)
Increases intensity of MR and MVP (MVP duration decreases)
- Amyl nitrate has what physiological effect?
- What happens to MVP, MR, HOCM, and AS with amyl nitrate use?
- Decreases afterload, so its easy for blood to be pushed into systemic circulation.
- Decreases MVP (intensity) and MR

- Kussmaul’s sign: exam findings
- associated conditions?
- Paradoxical increased JVP on INSPIRATION
- seen with constrictive pericarditis, cardiac tamponade, RV infarct

Trace pedal edema, petechiae over feet, lungs clear, pansystolic murmur 2/6 at LSB. tender hepatomegaly. EKG = ST-T wave changes and 1st degree AV block. CXR = cardiomegaly. DX?
Constrictive pericarditis (can cause congestive hepatopathy and eventually cirrhosis)
The best management for a pt with mitral stenosis with valve surface area < 1.5 sq cms?
Percutaneous balloon valvuloplasty; if no more than mild MR, no atrial thrombus, and no more than moderate annular calcification
HTN w/ systolic HTN in elderly woman
candesartan
HTN with aortic regurgitation
ACEI, ARB, dihydropyridine CCB
Frequency of AAA screening depends on size of the aneurysm.
<3 cms –>
3-3.4 cm –>
- 5 - 4.5 cm –>
- 5 - 5.5 cm –>
<3 cms –> 5 yrs
3-3.4 cm –> 3 yrs
- 5 - 4.5 cm –> 1 yr
- 5 - 5.5 cm –> 6 months
Preferred medications to maintain rhythm control in pts with afib.
NO STRUCTURAL HEART DISEASE.
- propafenone
- flecanide
- sotalol
Preferred medications to maintain sinus rhythm in pts with afib and a history of CHF, LVH, or CAD.
- amiodarone
- dofetilide
82 yo woman trips and falls and becomes unresponsive for a few mins. PMHx on non-valvular afib, w/ hx of TIA and HTN on warfarin and HCTZ. CT head shows soft tissue swelling but no fracture or bleed. wtd??
restart warfarin 2 wks later.
Genotyping VKORc1 +/- CYP2C9 has helped with dosing for which medication>
warfarin
Initial steps in fast AVNRT
- carotid massage
- adenosine 6mg IV, then 12mg IV
adenosine does not work in afib/flutter
What condition is a/w large pulse pressure and water hammer (Corrigan) pulse?
aortic regurgitation
Wide QRS, STE and TWI in R precordials, with what looks like RBBB
Brugada syndrome, auto-dominant, sodium channel mutation. Rx with ICD in patients with syncope
Aortic Aneurysms
- greatest risk of expansion?
- when to do elective repair?
- screening for whom?
- greatest risk: smoking
- elective repair: at 5.5 cm size or > 0.5cm growth/year
- men who have ever smoked > 65yo
Indications for permanent pacing (5)
- 3rd degree heart block
- 2nd degree type II heart block
- symptomatic 2nd degree type I heart block
- symptomatic bradycardia
- asystole with > 3 sec pause
WTD when you have a patient with syncope and hx is consistent with vasovagal etiology (classic trigger is prolonged standing) and there are no high risk features?
discharge to home, follow up with PCP
Aortic dissection
- risk?
- dx modality?
- risk: HTN, smoking, Marfan, coarctation
- dx with CT angio or TEE
Treatment for aortic dissection with pericardial effusion?
This is a type A dissection and may lead to tamponade and cardiogenic shock. DO NOT do pericardiocentesis; get surgical consult instead
Monitoring for aortic aneurysm
- < 3.0 cm
- 3.0-4.0 cm
- 4.0-5.4 cm
- screen with abdominal US
- < 3.0cm: no surveillance
- 3.0-4.0cm: q2-3years
- 4.0-5.4cm: q6-12mo
PAD
- ABI value for moderate and severe
- medical rx
- surgical rx
- ABI <0.90 = moderate; ABI <0.40 = severe
- medical rx: ASA (+/- DAPT), statin, cilostazole (pentoxifylline has limited benefit), supervised exercise for ALL
- surgical rx: only for most severe cases (pain at rest)
*
Etiologies of orthostatic hypotension (3)
- dehydration
- medications
- autonomic dysfunction
CCBs that affect the AV node and can cause bradycardia
Verapamil and diltiazem
NT pro-BNP
- higher average values for which patients
- lower average values for which patients
- higher average: for older people and CKD patients
- lower average: pts with higher BMI
Indications for CRT
EF < 35% and QRS > 150 and NYHA II-IV
Age to start lipid screening for men and women
35 for men and 45 for women; earlier if there are additional risk factors (tobacco use, DM, HTN, fam hx)
