CCI REGISTRY EXAM
CARDIOVASCULAR CREDENTIALING REVIEW
EXAM • 2026/2027 • 150 QUESTIONS
Practice Questions with Verified Answers, Detailed Rationales, and Citations to
ACC/AHA, ASE, IAC, SVU, and Federal Radiation Safety Standards
150 VERIFIED Q&As Randomized Choice Order Updated for 2026/2027 Full Rationales
Overview
This comprehensive study guide provides 150 realistic practice questions for candidates preparing
for Cardiovascular Credentialing International registry examinations in 2026/2027. Content spans
the invasive, echocardiographic, vascular, and electrophysiology domains, and every item includes
a standards citation, a written rationale, and a full distractor analysis explaining why each incorrect
option fails.
A note on credentialing authority: CCI is a not-for-profit certifying body that credentials individuals across nine
programs, including RCIS, RCS, RCCS, RVS, RCES, ACS, CCT, CRAT, and RPhS. CCI holds accreditation from the
ANSI National Accreditation Board under ANSI/ISO/IEC 17024. Facility accreditation is granted separately by
the IAC, educational programs are accredited by CAAHEP on recommendation of the JRC-CVT, and heart rhythm
credentials such as CEPS and CCDS are issued by IBHRE. Because CCI administers several distinct registry
examinations rather than one, this bank covers the full cardiovascular knowledge base across all major domains.
✓ KEY FEATURES
• 150 unique, verified questions with zero duplicate stems

SECTION 1: INVASIVE CARDIOVASCULAR TECHNOLOGY (30
QUESTIONS)
Cardiac catheterization, hemodynamic monitoring, vascular access, and interventional procedures
1. The normal mean right atrial pressure is:
A. 10 to 15 mmHg
B. 15 to 25 mmHg
C. 25 to 30 mmHg
D. 2 to 6 mmHg
Correct Answer: D. 2 to 6 mmHg
ACC/AHA hemodynamic reference standards; SCAI cath lab guidelines
Rationale: Normal mean RA pressure is low, and elevation suggests volume overload, right heart failure, or
pericardial disease.
Distractor Analysis:
A is incorrect: "10 to 15 mmHg" — violates ACC/AHA hemodynamic reference standards; SCAI cath lab
guidelines and would breach scope/safety vs correct practice.
B is incorrect: "15 to 25 mmHg" — violates ACC/AHA hemodynamic reference standards; SCAI cath lab
guidelines and would breach scope/safety vs correct practice.
C is incorrect: "25 to 30 mmHg" — violates ACC/AHA hemodynamic reference standards; SCAI cath lab
guidelines and would breach scope/safety vs correct practice.
2. Normal right ventricular pressure is approximately:
A. 90 to 140 mmHg systolic over 10 to 16 mmHg diastolic
B. 15 to 25 mmHg systolic over 40 mmHg diastolic
C. 20 to 30 mmHg systolic over 2 to 8 mmHg diastolic
D. 4 to 12 mmHg systolic over 0 mmHg diastolic
Correct Answer: C. 20 to 30 mmHg systolic over 2 to 8 mmHg diastolic
ACC/AHA hemodynamic reference standards
Rationale: RV systolic pressure equals pulmonary artery systolic pressure in the absence of pulmonic stenosis.
Distractor Analysis:
A is incorrect: "90 to 140 mmHg systolic over 10 to 16 mmHg diastolic" — violates ACC/AHA hemodynamic
reference standards and would breach scope/safety vs correct practice.
B is incorrect: "15 to 25 mmHg systolic over 40 mmHg diastolic" — violates ACC/AHA hemodynamic
reference standards and would breach scope/safety vs correct practice.
D is incorrect: "4 to 12 mmHg systolic over 0 mmHg diastolic" — violates ACC/AHA hemodynamic reference
standards and would breach scope/safety vs correct practice.

3. Normal pulmonary capillary wedge pressure is:
A. 15 to 25 mmHg
B. 4 to 12 mmHg
C. 25 to 35 mmHg
D. 0 to 2 mmHg
Correct Answer: B. 4 to 12 mmHg
ACC/AHA hemodynamic reference standards
Rationale: PCWP approximates left atrial pressure and, absent mitral stenosis, left ventricular end-diastolic
pressure.
Distractor Analysis:
A is incorrect: "15 to 25 mmHg" — violates ACC/AHA hemodynamic reference standards and would breach
scope/safety vs correct practice.
C is incorrect: "25 to 35 mmHg" — violates ACC/AHA hemodynamic reference standards and would breach
scope/safety vs correct practice.
D is incorrect: "0 to 2 mmHg" — violates ACC/AHA hemodynamic reference standards and would breach
scope/safety vs correct practice.
4. The pulmonary capillary wedge pressure is obtained by:
A. Advancing the catheter into the left atrium directly
B. Deflating the balloon in the right ventricle
C. Inflating the balloon at the catheter tip in a distal pulmonary artery branch
D. Positioning the catheter in the coronary sinus
Correct Answer: C. Inflating the balloon at the catheter tip in a distal pulmonary artery
branch
SCAI right heart catheterization standards
Rationale: Balloon inflation occludes antegrade flow, creating a static column that reflects downstream left
atrial pressure.
Distractor Analysis:
A is incorrect: "Advancing the catheter into the left atrium directly" — violates SCAI right heart
catheterization standards and would breach scope/safety vs correct practice.
B is incorrect: "Deflating the balloon in the right ventricle" — violates SCAI right heart catheterization
standards and would breach scope/safety vs correct practice.
D is incorrect: "Positioning the catheter in the coronary sinus" — violates SCAI right heart catheterization
standards and would breach scope/safety vs correct practice.
5. On a right atrial pressure waveform, the a-wave represents:
A. Ventricular contraction
B. Atrial contraction
C. Atrial relaxation
D. Rapid ventricular filling
Correct Answer: B. Atrial contraction
SCAI hemodynamic waveform interpretation standards
Rationale: The a-wave follows the P wave on ECG and is absent in atrial fibrillation.
Distractor Analysis:
A is incorrect: "Ventricular contraction" — violates SCAI hemodynamic waveform interpretation standards
and would breach scope/safety vs correct practice.
