– For secondary prevention if:
hx of significant vent arrhythmia or cardiac arrest
• BiV Pacemaker (Cardiac Resynchronization Therapy)
– In CHF, interventricular conduction delay is common -> poor coordination of
ventricular contraction -> poor hemodynamics
– BiV device: one lead pacing RV, one lead in RA to sense intrinsic rhythm, one
lead in coronary sinus to pace LV

A 45-year-old man with NICM presents to the ED with progressive shortness of breath over one
month and edema but no chest pain. Previously, he was symptomatic with moderate activity
(New York Heart Association class II heart failure). He has a dual-chamber implantable ICD.
Current medications are lisinopril, furosemide, and carvedilol; however, he ran out of carvedilol 6
weeks ago. His most recent echocardiogram 3 months ago showed an EF of 20%.
On exam, he is afebrile, BP 80/50 mm Hg, HR 115/min, and RR 16/min. He has jugular venous
distention. Heart rhythm is regular, and an S3 is heard. Lung examination reveals crackles. Edema
is present. The extremities are cool, and mentation is intact.
Pertinent laboratory results include serum sodium, 130 meq/L, creatinine, 2.6 mg/dL (was normal

Cardiogenic Shock
•
Causes:
– Extensive MI (75%), myocarditis, end stage CM, prolonged bypass, etc
•
Criteria:
– Sustained hypotension + decreased CI (<2.2 L/min/m2) + increased PCWP
•
If evidence of inadequate perfusion, need INOTROPIC support
– Dobutamine – inotrope with some vasodilation
– Dopamine (low-med dose)
•
•
•
1-5µg/kg/min = increased renal blood flow and urine output (dopaminergic agonist properties)
5-15µg/kg/min = increased renal blood flow, increased HR, increased cardiac contractility/cardiac
output (beta-agonist)
>15µg/kg/min = vasoconstriction (alpha-agonist)
– Milrinone – Phosphodiesterase inhibitor in cardiac and vascular tissue – vasodilation and
inotropic effects
•
•
watch for worsened hypotension; don’t use in renal failure
If refractory to meds, consider Intraaortic Balloon Pump
– Inflates during diastole to help with coronary perfusion
– Deflates during systole to help decrease afterload
•
If still refractory, consider LVAD or transplant

A 77-year-old woman is admitted to the hospital for intermittent dizziness over the past few days.
She does not have chest discomfort, dyspnea, palpitations, syncope, orthopnea, or edema. She
underwent coronary artery bypass graft surgery 6 years ago after a myocardial infarction. She has
hypertension, hyperlipidemia, and paroxysmal atrial fibrillation with a history of rapid ventricular
response. She notes that over the past several years, she feels she has slowed down and has had
problems with memory, which she attributes to aging. Medications are metoprolol, HCTZ,
pravastatin, lisinopril, aspirin, and warfarin.
On physical examination, her blood pressure is 137/88 mm Hg and her pulse is 52/min. Estimated
central venous pressure is 7 cm H2O. The point of maximal impulse is felt in the fifth intercostal
space and at the midcostal line. Cardiac auscultation reveals bradycardia with regular S1 and S2, as
well as an S4. A grade 2/6 early systolic murmur is heard at the left upper sternal border. The

A 54-year-old man is evaluated for recurrent arrhythmia. He was diagnosed with atrial flutter
with a rapid ventricular response 6 weeks ago. Rate control was initially difficult to achieve; he
underwent cardioversion and was started on metoprolol. He has had general fatigue since
initiation of metoprolol. Two days ago, he had a recurrence of his arrhythmia; his fatigue
worsened, and he began experiencing dyspnea on exertion. He denies chest pain,
lightheadedness, and heart racing. He has no other medical problems, and his only other
medication is daily aspirin.
On physical examination, his blood pressure is 123/65 mm Hg and his pulse is 50/min. BMI is 24.
Cardiac examination reveals bradycardia with an irregular rhythm, normal S1 and S2, and no
murmurs or gallops. Lungs are clear to auscultation. The electrocardiogram shows atrial flutter

A 67-year-old man presented to the emergency department 2 days ago with an acute STelevation myocardial infarction. During the initial evaluation, he became unresponsive due to
ventricular fibrillation. He was successfully resuscitated and taken to the cardiac catheterization
lab, where a 100% occlusion of his proximal left anterior descending artery was stented. His
postinfarction course was notable for mild heart failure, which has now resolved. He is now
stable on his current medical regimen. Current medications include aspirin, metoprolol,
atorvastatin, clopidogrel, and lisinopril.
On physical examination, his blood pressure is 115/72 mm Hg, his pulse is 65/min, and his

A 35-year-old black woman is evaluated for progressive dyspnea 3 weeks after delivery of her
first child. Other than hypertension during pregnancy, the pregnancy and delivery were
uncomplicated. She has no history of cardiovascular disease.
On physical examination, the blood pressure is 110/70 mm Hg in both upper extremities, the
heart rate is 105/min and regular, and the respiratory rate is 28/min. The estimated central
venous pressure is 10 cm H2O and there are no carotid bruits. The apical impulse is displaced and
diffuse. There is a grade 2/6 holosystolic murmur noted at the apex. Third and fourth heart
sounds are also noted at the apex. There is dullness to percussion at the posterior lung bases
bilaterally, and there are crackles extending up half of the lung fields. Lower extremity pulses are
normal and without delay, but pedal edema is present.

A 32-year-old woman presents for evaluation of a murmur recently heard on physical
examination. She has noted mild reduction in exercise capacity over the past 6 to 12 months. She
has no known history of cardiovascular disease, although a murmur was reported early in life.
On physical examination, the blood pressure is 100/70 mm Hg and the pulse is 68/min and
regular. The estimated central venous pressure is mildly elevated; the jugular venous pulse
contour demonstrates equal a and v waves. The apical impulse is not displaced. There is an
impulse noted along the left sternal border. The S1 is normal. The S2 is split throughout the
respiratory cycle. A grade 2/6 midsystolic murmur is noted at the second left intercostal space.
There is a grade 2/6 diastolic rumble noted at the lower left sternal border. Both of these
murmurs increase with inspiration. The remaining findings on physical examination are
unremarkable. An electrocardiogram demonstrates normal sinus rhythm with normal axis and

Adult Congenital Heart Disease - Pearls
• ASD
*Fixed Split S2, midsystolic flow murmur & tricuspid diastole rumble
*a wave = v wave
• VSD
– Holosystolic murmur at LLSB (often obliterates S2)
– If large, can cause Eisenmenger’s syndrome (irreversible pulm vascular disease due
to longstanding shunt with reversal of flow)
– Down’s syndrome
• PFO
– Often found in adults when they present with stroke (paradoxical embolus)
– Some association with migraine headaches
• Coarctation
– Associated with Turner’s and bicuspid Aortic valve
– Increased BP in arms compared to legs, radial-to-femoral artery delay, systolic
murmur often with +S4, “rib notching” and “figure 3 sign” on CXR
• PDA
– Persistence associated with maternal rubella and premies
– “Machine-like” murmur at L infraclavicular area, wide pulse pressure

A 57-year old man is evaluated for cramping discomfort in the right thigh, which occurs when
walking two blocks and is relieved quickly with rest. The patient is a house painter who goes up
and down ladders frequently in the course of his work. He is a current smoker with a 40-packyear history. His brother has coronary artery disease, and his mother died at age 65 of a heart
attack. He is taking no medications.
On physical examination, his temperature is normal, pulse is 72/min and regular, and his
respiration rate is 16/min. The blood pressure in his right and left arms is 140/84 mm Hg and
140/82 mm Hg. His highest right ankle/foot systolic pressure is 138 mm Hg, and his highest left
ankle/foot systolic pressure is 142 mm Hg. Examination of his lower extremities reveals scant hair
present below mid-shin level. There is no abdominal or femoral bruit. Distal pulses are present
but diminished. Capillary refill in the toes is intact, and there is no
pedal edema,

A 68-year-old man is evaluated for left calf pain that occurs after walking 2 to 3 blocks and is
relieved with rest; he has had the pain for about 6 months. He has a history of coronary artery
disease with depressed left ventricular systolic function (left ventricular ejection fraction, 30%)
treated with coronary artery bypass grafting 2 years ago and subsequent implanted cardiac
defibrillator placement for primary prevention purposes. He has hypertension and
hyperlipidemia, and is a prior cigarette smoker. His medications include atorvastatin, aspirin,
metoprolol, and lisinopril.
On physical examination, blood pressure is 110/70 mm Hg, pulse is 68/min and regular, and
respiration rate is 16/min. Peripheral pulses are diminished. There is no skin breakdown or
ulceration and no abdominal or femoral bruits. Ankle-brachial index is 0.7 on the left and 1.0 on
the right. Segmental plethysmography demonstrates a pressure drop of 20 mm Hg below the left

A 72-year-old man is evaluated in the emergency department for acute severe pain during rest in
the lower left leg that began 3 days ago. The patient has repeatedly used
oxycodone/acetaminophen that he had at home for relief of pain. His pain is now much better,
but he finds that he is having difficulty walking. He has had progressive exertional pain in the
lower left leg over the past year. Five years ago, he had a left femoral popliteal bypass for
occlusive peripheral arterial disease with distal ulceration. He has hypertension and
hyperlipidemia. He has a 50 pack-year smoking history. Current daily medications include aspirin,
lisinopril, hydrochlorothiazide, and simvastatin.
On physical examination, the patient’s temperature is 37.8 °C (100.1 °F), blood pressure is 106/60
mm Hg, pulse is 100/min, and respiration rate is 20/min. The left lower extremity is pale and cool
from the toes to the mid shin, and there is a small ulceration on the ball of the left foot. The left
posterior tibialis and dorsalis pedis pulses are not palpable and cannot
