✍️ Sample CSC Questions & Answers

1. What is the typical target mean arterial pressure (MAP) during cardiopulmonary bypass for most adult patients?

✓ 50–80 mmHg

A MAP of 50–80 mmHg is generally maintained during CPB to ensure adequate end-organ perfusion while minimizing bleeding risk.

2. Deep hypothermic circulatory arrest (DHCA) is used in aortic arch surgery primarily to:

✓ Provide a bloodless operative field while protecting the brain and organs during circulatory pause

DHCA cools the patient to 15–20°C, dramatically reducing cerebral metabolic demand and allowing safe cessation of circulation for arch reconstruction.

3. Systolic blood pressure that is higher than average is a sign of abnormal pulsus paradoxus.

✓ More than 10 mm Hg lower during inhalation than exhalation

Systolic blood pressure that is noticeably lower during intake than expiration is known as pulsus paradoxus. A pulsus paradoxus with a difference of more than 10 mm Hg is regarded as abnormal and is frequently a symptom of cardiac tamponade. It is normal to experience a drop in blood pressure of 10 mm Hg or less during inspiration, but a larger pressure difference could be a sign of various cardiopulmonary complications, such as pericardial effusion, pericarditis, pulmonary embolism, cardiogenic shock, chronic obstructive pulmonary disease, asthma, and obstruction of the superior vena cava. If pulsus paradoxus is discovered, blood pressure data should be reassessed to guarantee accuracy.

4. Emergency CABG is most commonly indicated after failed PCI in the setting of:

✓ Acute coronary occlusion with hemodynamic compromise unresponsive to catheter-based intervention

Emergency surgical revascularization is indicated when PCI fails to restore flow and ongoing ischemia with hemodynamic instability persists, requiring immediate coronary bypass.

5. Intraoperative graft flow measurement using transit-time flowmetry is used to:

✓ Verify graft patency and detect technical errors before chest closure

Transit-time flowmetry measures actual blood flow through each graft, identifying low-flow or pulsatility index abnormalities suggesting technical problems requiring revision.

6. What is the purpose of a left ventricular vent during cardiopulmonary bypass?

✓ To prevent left ventricular distension and reduce myocardial work

The LV vent decompresses the left ventricle, preventing distension that can cause myocardial injury when the heart is arrested.
