1
Q
Abdominal aortic aneurysm screening. When, how, who
A
Abdominal ultrasound is used to screen for abdominal aortic aneurysm (AAA) in men age 65-
75 with a smoking history.
2
Q
, patients age <45 with AUB who have failed medical management require what
A
an endometrial biopsy.
3
Q
Why is a hystersalpkngogram and ablation CI in AUB, when not identified cause
A
Could be CA, and therefore CA can be spread
4
Q
Why do patients with AUB refractory to COCP need biopsy
A
In such patients, the endometrial lining is likely too thick for the progestin to completely shed the endometrium during menstruation; as a result, the unshed endometrium continues to undergo dysregulated proliferation, which leads to an increased risk of endometrial hyperplasia/cancer.
5
Q
Three main indications to biopsy endometrium in AUB <45 yo
A
indications for endometrial biopsy in women age <45 include persistent (>6 months) AUB, obesity, or
tamoxifen therapy, all of which increase the amount of unopposed endometrial estrogen exposure. Also if there is failed medical therapy
6
Q
Main risks of vecicular vaginal fistula
A
due to young maternal age (ie, small pelvis) and limited or no prenatal care, which results in delayed diagnosis and labor intervention. Obstructed labor is the most common cause.
continuous vaginal discharge with an abnormally elevated pH (ie, >4.5) due to urine,
which may be malodorous due to surrounding necrotic tissue. Pelvic examination typically shows vaginal
pooling of urine, a visible defect, or an area of raised, red granulation tissue on the anterior vaginal wall.
Bladder dye testing is performed to confirm the diagnosis,
7
Q
Echo finding for MS
A
Increased transmittal flow velocity
8
Q
Run through Dukes criteria for endocarditis
A
BE FIVOR
Bacteraemia, endocardial signs (mama), fever, immune phenomena, vascular phenomena, organism culture, risk factors.
B and E are the major criteria. The rest are minor. Diagnose i.e. if two major, or one major and three minor, or five minor
9
Q
If CHADVAS says so… how do we prevent thromboemb in AF
A
NOACs are best. Not anti PLT for sure
10
Q
HTN and Low dose diuretic causing significantly low K+…. Cause?
A
Primary hyperaldo
11
Q
An early peaking systolic murmur is seen in mild or severe AS
A
Mild AS
12
Q
A loud S1 is seen in which murmur
A
M.S.
13
Q
Some differences between athletes heart and hypertrophic cardiomyopathy
A
Hypertrophic cardiomyopathy will have focal areas of enlargement (IV septum).
Cavity of the left ventricle will be decreased in HCM (it is usually increased in athletes). The thickness is usually above 15 mm in HCM. Diastolic function is compromised in HCM. The left atria can be enlarged in HCN.
14
Q
What is masked hypertension
A
Hypertension fluctuates throughout the day, making it hard to establish a diagnosis.
15
Q
Which cardiovascular issues are a contraindication for pregnancy
A
Symptomatic mitral stenosis, aortic stenosis. Heart failure with a ejection fraction of less than 30. Pulmonary artery hypertension. Should try and address these things and then do pregnancy
16
Q
Why is pregnancy a contraindication for patients with severe symptomatic M.S.and A.S.
A
In pregnancy we have an increase total volume, which will exacerbate the stretching of the heart, which could predisposed to emboli, AF, pulmonary oedema
17
Q
Mitral valve replacement surgery
A
Balloon mitral Valvulotomy. If you can’t do that you can do open mitral repair or replacement
18
Q
What medication can be given to help mitral stenosis in pregnancy
A
If a symptomatic, can give a beta blocker. This will decrease the heart rate, increase the left ventricle filling time, lowering the pressure in the left atrium. If symptomatic must do surgery before pregnancy
19
Q
What is the cornerstone for medical management 4NSTEMI
A
Dual antiplatelet therapy. P2Y 12 inhibitor and aspirin
20
Q
Do we give NOAC in acute coronary syndrome
A
No. Increases the risk of bleeding. So we do dual antiplatelet, and a bit of low molecular weight heparin
21
Q
Murmur of both papillary muscle rupture, and interventricular wall rupture
A
Papillary muscle rupture will cause a soft mitral regurgitation. Interventricular will rupture will cause a half pan systolic murmur had left sternal border plus a thrill.
22
Q
In a cute mitral regurgitation, do we see enlargement of the atria and ventricles
A
No, there is not enough time for eccentric hypertrophy. Therefore we don’t get accommodation of high-volume, so we get acute pulmonary oedema
23
Q
Indications for aortic valve replacement. Otherwise do what?
A
Severe AS & >=1 of the following:
• Onset of symptoms (eg, angina, syncope)
• Left ventricular ejection fraction <50%
• Undergoing other cardiac surgery (eg, CABG)
Severe AS see on another FC
Otherwise do serial monitoring with echo
24
Q
Criteria for severe AS
Jet velocity of….
Mean Transvaal u,at pressure gradient of….

93
Can prostaglandin be given after the ductus arteriosus is closed
Yes, it can reopen
94
What kind of check should turner syndrome patients have the cardiac problems
They need screening with for extremity blood pressure measurements, an echocardiogram. This can diagnose coartcion or bicuspid aortic valve
95
 How to differentiate between pleural friction rub and pericardial friction rub
Ask the patient to hold their breath, if the rub remains it’s pericardial
96
 Syncope with exertion, what are your thoughts
Either ventricular arrhythmia secondary to ischaemia, or an outflow obstruction like aortic stenosis
97
And when diagnosing coronary artery disease (angina), when is an exercise ECG test done
With intermediate pretest probability. In patients who can do exercising, and reach a target heart rate. ECG at baseline is normal. Not allowed if the patient has left bundle branch block, a pacemaker, patient unable to reach target heart rate
98
And when diagnosing coronary artery disease (angina), when is an exercise Donumatime stress test done
Of course when there is an intermediate pretest probability. I done when a patient is unable to meet the target heart rate, or has reactive airway disease. This is not allowed if somebody has a tachyarrhythmia
99
And when diagnosing coronary artery disease (angina), when is a Coronary steel stress test done
Of course done when there is intermediate pretest probability. Good if the patient has left bundle branch block, a pacemaker, unable to reach target heart rate. Not allowed if the patient has reactive Airway disease, or is on dipyridamole or theophylline
100
How does COPD, or severe asthma cause pulsus paradoxus
It creates negative pressure in the thorax, which when breathing in causes big drop in intrathoracic pressure. The pressure causes blood to pool in the pulmonary vasculature, leading to less ventricular preload
101
How can an aortic regurgitation even prevent pulses paradoxus in patients with Tamponade
Severe regurgitation will cause higher left ventricle and diastolic pressure, that would preclude the IV septum from shifting into the left ventricular cavity
102
Mamma heard in co-arched aorta
Systolic heard at the left infraclavicular area anteriorly and left interscapular area posteriorly
103
Clues for syncope being cardiac origin
Sudden onset, no prodromal, heart structural issues, occurs at rest or excretion, ECG clues
104
Discuss the murmur heard in atrial myxoma
Because the mass is typically mobile, obstructive symptoms may be transient and influenced by position (ie, mitral obstruction is exacerbated by upright posture but is alleviated by lying down); tumor movement occasionally causes a characteristic "tumor plop" sound at the end of diastole on auscultation.

Peri valvular abcess
112
Perivalvular abcess sus, invx?
TEE echo
113
Eccentric hypetrophy. Compensation to decomp story
Increase LV VOL. increase stretch and thus SV (frank starling). More vol means eccentric hypertrophic over time. Keeps SV, but wall stress increases. Eventuallly stress is too much and we decompensate.
114
What is the passive and active cause for pulmonary artery BP to increase in MS/left HF
The passive (or postcapillary) component of pulmonary hypertension is most prominent and results from transmission of elevated pressure backward from the left atrium to the pulmonary veins, pulmonary capillaries, and pulmonary arteries. Clinically, this process is typically evidenced by pulmonary edema and its associated symptoms (eg, orthopnea,
paroxysmal nocturnal dyspnea, hemoptysis), as well as peripheral edema.
• The reactive (or precapillary) component of pulmonary hypertension is only sometimes present and occurs independent of left atrial pressure. In this process, MS triggers endothelin-mediated pulmonary arteriolar vasoconstriction and pathologic vascular remodeling through a poorly understood mechanism.
115
PAH vs other pulmonary HTN Mx approach
PAH, use endothelium antag, prostenoids, PDE inhib etc.
Other pulmonary HTN, focus on cause
116
Flags to suggest psychigeninc psuedosyncope….. aka conversion disorder
Prolonged LOC (eg, 20 min): PPS episodes typically last many minutes to hours versus approximately 1-2 minutes in
syncope.
• Absence of objective findings during the episode: As in this patient, typical objective findings accompanying syncope
(eg, abnormal vital signs, pallor, sweating) are usually absent on examination.
• Patient's reports of symptoms/events that occurred during the episode (eg, "I felt my head throbbing after it hit the
floor"): This awareness rules out true LOC. Symptoms are often reported in a detached or disassociated manner (la
belle indifférence).
117
Discuss the retroperitoneal hematoma from cardiac catheterisation
If the arterial puncture site is
above the inguinal ligament, the hematoma can extend into the retroperitoneal space, even with minimal visible localized
hematoma, and present with sudden hemodynamic instability and ipsilateral flank or back pain.
118
 Seizure versus syncope
Consider preceding symptoms, patient position, tongue biting, convulsive movement, urine incontinence, post episode recovery
Seizures have auras, syncopating may have a prodrome (vasovagal). Seizure can happen in any position, syncope can happen when standing in vasovagal only. Tongue biting is very indicative of seizure. Convulsive movements can be seen in both (is usually before or with the consciousness loss in seizure, and after the LOC in syncope). Your incontinence is seen more in seizure. Post-episode recovery is usually longer in seizure
119
Which symptom in seizures has the highest specificity against Syncope
Tongue biting
120

121
 Patient with recurrent palpitations, potential arrhythmia. Do ECG a normal. Might we have to do to identify this problem
24 hour ambulatory monitoring
122
What is the most common cause for foci in atrial fibrillation
Usually left atrial enlargement. Most of the time it’s hypertension, causing left ventricle hypertrophy, decreasing diastolic volume, transferring the pressure back to the left atria, causing it to enlarge. This can create an atrial substrate for a fib
123
Changes in right ventricular preload, left on curricular preload, SVr in right-sided is STEMI
Right ventricular preload increase, left entrepreneur decrease, SVR increase
124
ALS guidelines for treatment of:
A fib or a flutter
Superventricular tachycardia
A fib with aberrant conduction
Monomorphic VT
Rate control
Vago manoeuvre, Than adenosine
Rhythm control
Pharmacological cardioversion (amiodarone, procainamide, lidocaine, sotalol
125
Amiodarone is a good rhythm control drug. How does it also have some rate control elements
It’s a potassium channel blocker, but also blocks some calcium channels in the AV node, thus having rate control properties
126
Does decrease aortic compliance increase systolic or diastolic blood pressure
It increases the systolic blood pressure, and thus the pulse pressure
127
How does a mild aortic regurgitation sound compared to a severe
Mild AR is heard only at early diastole, where as severe AR is heard throughout diastole
128
How does restrictive cardiomyopathy appear on an echo
Usually concentric hypertrophy, and atria enlargement.
129
Recall the presentation of restrictive cardiomyopathy
Predominantly right sided heart issue. JVD, ascites, hepato-megaly, pitting oedema. Concentric ventricular hypertrophy, with dilated atria. Diastolic dysfunction
130
Patient has aortic dissection, vitals are okay. History of kidney problems. Investigation of choice
Transoesophageal echocardiogram UF***Retard. Anyone with contrast allergy or renal problems must have for TEE instead of CTA
131
How might elevated systemic venous pressure is caused a protein losing enteropathy
Patients can get intestinal lymphangiectasia secondary to protein loss in the GI system.
132
What is the pericardial knock
A mid diastolic sound, that is indicative
133
134
Multifocal atrial, tachycardia management
 usually don’t have to treat. But definitely treat any underlying cause (pulmonary, septic, metabolic et cetera). If patient has ischaemia or heart failure signs due to this, we can give rate control therapy

151
Most common indication for pacemaker placement
Sick sinus syndrome (because of increased risk of AF or other superventricular tachyarrhythmias)
152
Why do patients with sick sinus syndrome get junctional escape
Because the P-wave has dropped, there is a long paws, so the ventricle generates its own rhythm.
153

Three months past history of MI, TIA, stroke, carotid stenosis, carotid atheroma, ventricle fibrillation, ventricular tachycardia
154
What is a retrograde P-wave
Essentially where the P-wave comes before the T-wave. And is often seen in AVNRT or AVRT
155
If an AVRT is secondary to wolf Parkinson white, how do we treat
