Mixed Deck — All CSC Topics Flashcards

Which maneuver would cause the murmur of hypertrophic obstructive cardiomyopathy (HOCM) to increase in intensity?

Answer: Standing from squatting position

Standing from squatting reduces venous return and LV volume, increasing LVOT obstruction and intensifying the HOCM murmur; squatting does the opposite.

How should Cardiac Subspecialty Certification Exam professionals handle conflicts with stakeholders?

Answer: Address issues professionally through active listening, finding common ground, and seeking resolution

This is fundamental to Cardiac Subspecialty Certification Exam practice. Address issues professionally through active listening, finding common ground, and seeking resolution represents the professional standard for communication in the CSC certification framework.

How should an CSC professional approach a novel situation not covered by standard procedures?

Answer: Apply foundational principles, assess risks, consult resources, and document the rationale for decisions

This is fundamental to Cardiac Subspecialty Certification Exam practice. Apply foundational principles, assess risks, consult resources, and document the rationale for decisions represents the professional standard for practical in the CSC certification framework.

A patient with inferior MI develops sudden hypotension, clear lung fields, and elevated JVP. Which complication is most likely?

Answer: Right ventricular infarction

RV infarction complicates inferior MI (RCA territory) and presents with hypotension, elevated JVP, and clear lungs because the failing RV cannot fill the LV adequately.

How do CSC professionals maintain digital competency?

Answer: Through ongoing training, practice with new tools, and staying current with technological advances

This is fundamental to Cardiac Subspecialty Certification Exam practice. Through ongoing training, practice with new tools, and staying current with technological advances represents the professional standard for technology in the CSC certification framework.

Pulse pressure variation (PPV) >13% during mechanical ventilation suggests:

Answer: Fluid responsiveness

PPV >13% in mechanically ventilated patients with sinus rhythm indicates significant preload dependence and predicts that the patient will respond to fluid administration with increased cardiac output.

A 58-year-old diabetic woman presents with atypical chest pain. Her pretest probability of obstructive CAD is intermediate. Which initial diagnostic strategy is most appropriate?

Answer: Stress imaging (nuclear MPI or stress echo)

In patients with intermediate pretest probability and interpretable ECG but suboptimal exercise capacity, or atypical symptoms, stress imaging provides higher sensitivity and specificity than exercise ECG alone.

How do CSC professionals transfer knowledge from training to practice?

Answer: Through supervised practice, mentoring, gradual independence, and ongoing feedback

This is fundamental to Cardiac Subspecialty Certification Exam practice. Through supervised practice, mentoring, gradual independence, and ongoing feedback represents the professional standard for practical in the CSC certification framework.

A cardiac electrophysiology lab is implementing a new remote monitoring platform for implanted devices. Under HIPAA's Security Rule, which safeguard type specifically applies to the electronic transmission of device interrogation data?

Answer: Technical safeguards

Technical safeguards under HIPAA's Security Rule govern the technology and related policies for protecting electronic PHI during transmission, including encryption requirements.

Systemic vascular resistance (SVR) is calculated using which formula?

Answer: (MAP – CVP) / CO × 80

SVR = (MAP – CVP) / CO × 80 (dynes·sec·cm⁻⁵), using the pressure gradient across the systemic circulation divided by flow.

A 49-year-old man undergoes PCI of the RCA with a drug-eluting stent. Two weeks later he requires urgent tooth extraction. What antiplatelet strategy is most appropriate?

Answer: Continue both aspirin and P2Y12 inhibitor throughout the dental procedure

Within 3–6 months of DES implantation, DAPT should not be interrupted for minor surgical procedures; continuing both agents during tooth extraction is acceptable.

What is a corrective action in Cardiac Subspecialty Certification Exam quality systems?

Answer: A systematic response to eliminate the cause of a detected nonconformity and prevent recurrence

This is fundamental to Cardiac Subspecialty Certification Exam practice. A systematic response to eliminate the cause of a detected nonconformity and prevent recurrence represents the professional standard for quality in the CSC certification framework.

In which clinical scenario is intravascular ultrasound (IVUS) guidance during PCI most strongly supported by evidence to improve outcomes?

Answer: Left main coronary artery PCI and complex bifurcation lesions

IVUS guidance during left main PCI improves stent sizing, deployment, and reduces major adverse cardiac events compared to angiography alone.

The American College of Cardiology's Appropriate Use Criteria (AUC) for cardiac imaging are intended to:

Answer: Reduce inappropriate testing by providing evidence-based guidance on imaging indications

AUC provide evidence-based guidance to help clinicians select the most appropriate imaging study for a given clinical scenario, reducing overuse and underuse.

In a scenario where a patient's pre-procedure INR is above the safe threshold for cardiac catheterization, the technologist's role is to:

Answer: Confirm the result has been communicated to the physician and document it appropriately

The technologist's responsibility is to verify communication of critical lab values to the physician and ensure proper documentation, not to independently manage or cancel the case.

In echocardiography QA, interobserver variability is best assessed by:

Answer: Comparing two readers' measurements of the same study using intraclass correlation coefficient (ICC)

The intraclass correlation coefficient (ICC) quantifies agreement between two or more raters measuring the same continuous variable on the same subjects.

Cardiac amyloidosis is increasingly recognized as a cause of heart failure with preserved ejection fraction. Which finding on bone scintigraphy (pyrophosphate scan) is most specific for transthyretin amyloidosis (ATTR)?

Answer: Grade 2 or 3 cardiac uptake with H/CL ratio >1.5 in the absence of monoclonal protein

Grade 2-3 cardiac uptake on pyrophosphate scintigraphy (H/CL >1.5) without monoclonal protein has >99% specificity for ATTR amyloidosis, obviating biopsy.

The Mason Likar modification is what?

Answer: A different arrangement for placing electrodes in a 12-lead EKG

The Mason-Likar modification is a specific technique used in electrocardiography, particularly during exercise stress tests. It involves repositioning the limb electrodes from the standard distal limb placement to the torso, which helps reduce motion artifact and improve signal quality during physical activity.

Which hemodynamic parameter defines pulmonary arterial hypertension (PAH) by current guidelines?

Answer: Mean PAP >20 mmHg at rest with PCWP ≤15 mmHg and PVR ≥3 WU

Updated 2022 ESC/ERS guidelines define PAH as mean PAP >20 mmHg, PCWP ≤15 mmHg, and PVR ≥3 Wood Units on right heart catheterization.

Which of the following scenarios represents an appropriate boundary between cardiac technologist and physician roles?

Answer: A technologist measuring and reporting LV ejection fraction to the interpreting cardiologist

Measuring and reporting quantitative findings like LVEF is within the sonographer's technical scope; diagnosis and treatment decisions belong to the physician.
