Mixed Deck — All CIR Topics Flashcards

What role does documentation play in patient education & health promotion within Cardiac Interventional Radiology?

Answer: It ensures continuity, accountability, and serves as a reference for all parties

Proper documentation ensures continuity of care or service, establishes accountability, and provides a reliable reference for all involved parties.

Which diagnostic procedures & interpretation method provides the MOST reliable results in Cardiac Interventional Radiology?

Answer: Standardized protocols with validated measurement tools

Standardized protocols and validated tools ensure consistency, reliability, and comparability of assessment results.

How should unexpected results during research methods & evidence-based practice be handled in Cardiac Interventional Radiology?

Answer: Document the findings, analyze potential causes, and consult protocols

Documenting unexpected findings, analyzing causes, and consulting established protocols ensures proper investigation and appropriate response.

Which factor BEST indicates mastery of pharmacology & treatment protocols in Cardiac Interventional Radiology?

Answer: The ability to adapt knowledge and skills to varying contexts while maintaining standards

True mastery is demonstrated by the ability to apply knowledge flexibly across different contexts while consistently maintaining quality standards.

What is the primary advantage of using a radial artery access site over femoral access for cardiac catheterization?

Answer: Significantly lower major vascular access-site bleeding complications

Radial access reduces major vascular bleeding complications and allows earlier ambulation compared to femoral access because the radial artery is superficial and easily compressible.

Which factor BEST indicates mastery of emergency response & critical care in Cardiac Interventional Radiology?

Answer: The ability to adapt knowledge and skills to varying contexts while maintaining standards

True mastery is demonstrated by the ability to apply knowledge flexibly across different contexts while consistently maintaining quality standards.

What is the purpose of balloon angioplasty?

Answer: Open narrowed blood vessels

Balloon angioplasty is a medical procedure designed to open narrowed or blocked blood vessels, typically caused by plaque buildup (atherosclerosis). A catheter with a deflated balloon is guided to the blockage, and the balloon is then inflated to compress the plaque against the artery walls, restoring proper blood flow. This intervention helps alleviate symptoms and improve cardiac function.

What imaging modality is commonly used to guide coronary interventions?

Answer: Fluoroscopy

Fluoroscopy is the most commonly used imaging modality in cardiac interventional radiology because it provides real-time, dynamic X-ray images. This continuous visualization allows interventional cardiologists to precisely guide catheters, guidewires, and contrast dye within the coronary arteries and heart chambers. It is crucial for accurate navigation, device placement, and monitoring the progress of procedures like angioplasty and stenting.

Which organization accredits cardiac catheterization laboratories in the United States and sets structural performance standards?

Answer: The Joint Commission (TJC)

The Joint Commission accredits catheterization laboratories and sets standards for quality, safety, and performance in interventional cardiology facilities.

Which element is ESSENTIAL for an effective professional ethics & legal standards program in Cardiac Interventional Radiology?

Answer: Regular audits and continuous monitoring processes

Regular audits and continuous monitoring enable early detection of compliance gaps and ensure ongoing adherence to standards.

What is a key component of pre-procedure assessment in cardiac interventional radiology?

Answer: Reviewing medication and allergy history

A thorough pre-procedure assessment is vital for patient safety in cardiac interventional radiology. Reviewing medication and allergy history helps identify potential drug interactions, contraindications for certain medications (like anticoagulants or contrast agents), and risks of allergic reactions. This information allows the medical team to make necessary adjustments to the procedure plan and ensure appropriate patient care.

Which contrast media property is MOST important for minimizing direct cardiac toxicity during intracoronary injection?

Answer: Low ionicity and low osmolality

Low ionicity reduces the direct electrophysiologic effects on myocardium while low osmolality minimizes osmotic stress on red blood cells and endothelium during coronary injections.

A cath lab's quality program should track door-to-balloon (D2B) time with a goal of less than:

Answer: 90 minutes

ACC/AHA guidelines recommend a door-to-balloon time of ≤90 minutes for primary PCI in STEMI patients to minimize myocardial damage.

A cardiac output of 4.0 L/min with a BSA of 2.0 m² yields a cardiac index of:

Answer: 2.0 L/min/m²

Cardiac index = CO / BSA = 4.0 / 2.0 = 2.0 L/min/m², which is at the lower limit of normal.

What is the function of contrast agents in interventional radiology?

Answer: To visualize blood vessels

Contrast agents, usually iodine-based, are injected into the bloodstream during interventional radiology procedures to visualize blood vessels. These agents absorb X-rays, making the vessels appear opaque on fluoroscopic images, allowing physicians to identify blockages, aneurysms, and other vascular abnormalities. This enhanced visualization is critical for guiding interventions and assessing vascular anatomy.

Which catheter design feature is most important for delivering a coronary stent to a distal lesion?

Answer: High pushability and low crossing profile

A low crossing profile allows the stent delivery catheter to pass through tight stenoses, while high pushability ensures the device can be advanced to distal target sites.

During coronary intervention, what does the term 'stent jail' refer to?

Answer: Caging of a side branch ostium by stent struts crossing it during main vessel stenting

Stent jail occurs when stent struts are deployed across a side branch ostium, restricting access; a guidewire must be re-crossed through the struts to treat the jailed branch if needed.

Fractional Flow Reserve (FFR) measurement requires pharmacologic hyperemia because:

Answer: Maximal vasodilation eliminates microvascular resistance, isolating the stenosis as the sole flow-limiting variable

Adenosine-induced maximal hyperemia minimizes microvascular resistance so that the measured pressure gradient across the stenosis reflects only the epicardial lesion's hemodynamic significance.

Which hemostasis valve on a guide catheter allows instrument exchanges without significant blood loss or air entry?

Answer: Y-connector with rotating hemostatic valve

The Y-connector with a rotating hemostatic valve seals around guidewires and devices during exchanges while the side port allows continuous flushing.

Which type of contrast media is preferred for cardiac catheterization due to its lower risk of adverse hemodynamic effects?

Answer: Low-osmolar non-ionic contrast media

Low-osmolar non-ionic contrast media is preferred because it produces fewer hemodynamic disturbances and cardiac side effects compared to high-osmolar ionic agents.
