Cardiology 1 Flashcards
When is Surgery indicated for Infective Endocarditis (5)?

- Rx for type B?
- CT angiography
- Beta blockers (Esmolol) to get pressure < 120 mmg Hg. Add vasodilators (Nitroprusside) if needed medically treat first for patients without shock.
- Type A treatment is Surgery
- Type B treatment is Medical Therapy Alone, unless complicated.
Rx of patients with Aortic Atheroma?
Stains and Plavix to reduce systemic Embolism and Stroke
Indications for Prophylactic TAA (Thoracic Aortic Aneurysm) Surgery (3)?
- Aortic Diameter > 5.0 cm
- Aortic diameter > 4.5 cm and undergoing heart surgery for something else

- Years. Months.
Measurements to determine Severe AS?
Valve area < 1.0cm2 and Mean Gradient > 40 mm Hg
What is the next step in management when there is discrepancy btw Aortic Valve Area on Echo and Symptoms within the patient? (Valve area only 1.5cm and a Mean Gradient of 28 mmhg, (Pt presents with carotid tardus, diminished aortic component of S2, late peaking systolic murmur.)
Cardiac Catherization.
The Echo can underestimate the Transvalvular Gradient in patients with Severe LV Dysfunction. (pseudo-steonosis)

Man that is otherwise healthy has a grade 2/6 Diastolic Decrescendo murmur heard at Right lower sternal border and Echo shows Bicuspid Aortic Valve, Ascending aorta is enlarged with dimension 42mm. Next step in management?
CT angio of Aorta. To check for Dissection, Aneurysm, Corarctation.
- Accessory Pathway Mediated Tachycardia which is observed as Pre-excitation. (Short RP interval, Retrograde P wave) ?
- When is it called WPW?
AVRT
When symptoms are present. WPW syndrome.
Rx for SVT?
How to treat recurrent AVNRT?
What does it mean if there is progression of p wave after adenosine is given?
Definitive Rx?
Valsalva, Carotid Massage, cold water immersion, Adenosine.
CCB and Beta blocker prevent recurrent.
Means Afib, Aflutter (continue P waves despite AV block).
Ablation is definitive therapy.
What medications to avoid in AF with WPW? What is the complication.
(AV Nodal blocking Agents that cause overuse of the Accessory Pathway) -CCB, Beta blockers, dig. this can convert it to AF, VT, VF
Pt presents with JVD, peripheral edema, hypotension, pulsus paradoxus, enlarged cardiac silhouette on CXR and EKG shows evidence of electrical alterans. Dx?
Cardiac Tamponade

- Murmur with symptoms
Name that murmur: Mid-systolic, crescendo-decrescendo, Right upper sternal border radiating to carotid, clavicle, apex. Associated with enlarged non displaced apical impical impulse
AS
Name that murmur: Diastolic decrescendo murmur at left lower sternal border or right lower sternal border no radiation. Associated with bounding pulses , increased pulse pressure, enlarge displaced apical impulse
AR
Name that murmur: Diastolic, low pitched decrescendo murmur heard at apex no radiation associated with loud S1, opening snap after S2.
What is the next best step which patients have discrepancy between there symptoms and echo?
MS
Exercise Echo
Name that murmur:
Systolic, holosystolic or later systolic murmur heard at apex radiates to axilla, Valsalva improves it, hand grip increases intensity
MR
Name that murmur:
Systolic crescendo- decrescendo murmur heard LEFT upper sternal border radiating to left clavicle associated with Pulmonic Ejection click after S1, diminishes with inspiration.
PS
- Name that murmur: Diastolic decrescendo murmur heard at left lower sternal sternal border associated with loud P2 if pulm HTN present and non radiating.
- What if it was associated with bounding pulses and increased pulse pressure and non radiating ?
- What if it was associated with elevated CVP and non-radiating?
PR
AR
TS
Name that murmur: Midsystolic grade 1/6 or 2/6 in intensity heard right upper sternal border associated normal intensity of A2 and normal splitting of S2, no radiation
Innocent flow murmur
Name that murmur: Systolic crescendo -descrscendo murmur heard at LLSB with enlarged hyperdynamic apical impulse, murmur increases with valsava and moving from squatting to standing position
Hypertrophic Obstructive Cardiomyopathy
Name that murmur:
Systolic Crescendo-Descrendo heard at Right Upper Sternal Border associated. Fixed Splitting S2, Right ventricle heave.
What if it there was radiation to Right Clavicle and Apex associated with Bicuspid Valve instead?
