- The CAQ-CVTS blueprint has five content domains: Cardiac 38%, Thoracic 28%, Critical Care 19%, Vascular 10%, Legal/Ethical 5%.
- Eight task categories, such as Pharmacotherapy at 20%, classify the same questions a second time and are not extra domains.
- The initial exam is 120 multiple-choice questions in two 60-minute blocks, and a completed block cannot be reopened.
- Use the blueprint's Vascular 10%, not the older weights printed in the 2021 sample-question annotations.
How NCCPA Classifies the Exam Content
The Certificate of Added Qualifications in Cardiovascular and Thoracic Surgery is an NCCPA credential. It supplements PA-C rather than replacing it, and it is not a physician surgical-board examination. That distinction matters for how you read the blueprint: the questions are written for physician assistants working in cardiovascular and thoracic surgical practice, so they test what a PA is expected to recognize, order, interpret, manage, and escalate in that setting.
NCCPA's content blueprint for this exam describes the content in two separate ways. The first is a set of five medical content categories (the domains this article covers). The second is a list of eight cross-cutting task categories. Every question belongs to one domain and one task at the same time. Candidates sometimes try to add the two lists together, but the percentages in each list sum to 100% on their own, so they are two views of the same 120 questions, not 13 separate areas.
One caution about the source itself: the blueprint is a three-page document that carries no date. The domain lines are official content categories, not a preparation curriculum, and the illustrative subtopics NCCPA lists are not exhaustive. Treat the domain names and weights as the authoritative skeleton, and treat the subtopics in this guide as examples of the kind of material a surgical PA should be comfortable with. If you are still confirming you qualify to sit, start with CVTS Requirements 2026: Eligibility, Prerequisites & How to Qualify.
| Domain | Weight | Approximate share of 120 questions |
|---|---|---|
| Cardiac | 38% | Roughly 46 questions |
| Thoracic | 28% | Roughly 34 questions |
| Critical Care | 19% | Roughly 23 questions |
| Vascular | 10% | Roughly 12 questions |
| Legal/Ethical Issues and Emerging Topics | 5% | Roughly 6 questions |
The question counts above are simple arithmetic from the published percentages applied to a 120-question exam. They are a planning aid, not a promise of how any individual form is assembled, so expect some variation.
Domain 1: Cardiac (38%)
Cardiac is the heaviest domain by a wide margin. Between the domain weight and the nature of cardiac surgery, this is where a typical CAQ candidate with an operating-room background should expect the most familiar ground, and also where the exam can be most exacting, because questions tend to ask for the next best step in a patient who is already complicated.
Cardiac: What Candidates Must Understand
Think across the whole arc of the cardiac surgical patient: preoperative evaluation, intraoperative events you assist with, and postoperative recovery on the floor and in the unit.
- Coronary artery disease and the decision logic between surgical and non-surgical revascularization
- Valvular disease: stenosis versus regurgitation physiology, timing of intervention, and prosthesis selection considerations
- Heart failure, cardiomyopathies, and when mechanical circulatory support enters the conversation
- Arrhythmias, particularly postoperative atrial fibrillation, conduction disturbances, and pacing wire management
- Aortic disease, including aneurysm and dissection recognition and management priorities
- Congenital and structural conditions as they present in adult surgical practice
- Common postoperative complications: tamponade, bleeding, low cardiac output, vasoplegia, and infection
Because pharmacotherapy and diagnostic interpretation cut across every domain, cardiac questions frequently combine them. A single item might present an echocardiographic finding, a hemodynamic profile, and a medication list, then ask what to change. Practice reading the whole stem before looking at the answer choices.
Domain 2: Thoracic (28%)
Thoracic is the second-largest domain, and it is the one most likely to be undertrained in candidates whose daily work is predominantly cardiac. At 28% of the exam, it is far too large to treat as an afterthought. A PA who spends most shifts on a cardiac service should deliberately schedule extra time here.
Thoracic: What Candidates Must Understand
This domain covers diseases of the lung, pleura, mediastinum, chest wall, airway, and esophagus as managed by a thoracic surgery team.
- Lung cancer workup and staging logic, including how imaging and tissue diagnosis drive resectability decisions
- Pulmonary nodules and mediastinal masses: evaluation pathways and indications for biopsy or resection
- Pleural disease: effusion, empyema, pneumothorax, and chest tube management principles
- Esophageal conditions, including motility disorders, reflux-related disease, and malignancy
- Preoperative pulmonary risk assessment, including pulmonary function interpretation
- Postoperative thoracic complications: air leak, atelectasis, pneumonia, bronchopleural fistula, and arrhythmia after lung resection
- Tracheal and airway problems and chest wall conditions
Chest tube management is a recurring practical theme. Know what bubbling, tidaling, and output volume tell you, and know the logic behind when a tube comes out versus when the problem needs intervention.
Domain 3: Vascular (10%)
Vascular is the smallest of the three clinical-surgical domains in absolute terms, but its weight is 10%, double what the Legal/Ethical domain carries. That is enough for roughly a dozen questions, and these are often the questions where candidates from purely cardiac or purely thoracic backgrounds lose easy points.
Vascular: What Candidates Must Understand
Focus on arterial and venous disease that a cardiothoracic surgical practice encounters or co-manages.
- Peripheral arterial disease and acute limb ischemia recognition
- Aortic and large-vessel pathology as it overlaps with cardiac surgery
- Carotid and cerebrovascular disease considerations in surgical patients
- Venous thromboembolism: prevention, recognition, and treatment
- Vascular access and graft or conduit considerations
- Postoperative vascular complications such as limb perfusion problems and access-site issues
Domain 4: Critical Care (19%)
Critical Care is the third-largest domain at 19%. It reflects the reality that cardiovascular and thoracic surgical PAs spend a large share of their patient contact time managing sick patients in the intensive care unit, often in the first hours and days after a major operation.
Critical Care: What Candidates Must Understand
Expect physiology-driven questions that ask you to interpret data and choose a management step.
- Hemodynamic monitoring and interpretation, including arterial lines, central venous pressure, and cardiac output assessment
- Shock states and their differentiation: cardiogenic, hypovolemic, distributive, and obstructive
- Vasoactive and inotropic medication selection and titration logic
- Mechanical ventilation, weaning, and extubation readiness after surgery
- Acid-base, electrolyte, and renal problems, including postoperative acute kidney injury
- Bleeding, coagulopathy, and transfusion decisions
- Sedation, delirium, and neurologic complications
- Sepsis and postoperative infection in the surgical ICU
Critical care items reward a systematic approach. Identify the physiologic problem first, then match the intervention to that problem, rather than reacting to a single abnormal number.
Domain 5: Legal/Ethical Issues and Emerging Topics (5%)
The final domain is the smallest at 5%, which translates to a handful of questions. It is also the easiest domain to under-prepare for, precisely because it feels peripheral to clinical work. Because the percentage is small, a modest investment of study time here can be worthwhile relative to the effort required.
Legal/Ethical Issues and Emerging Topics
These questions test professional judgment and awareness of evolving practice in the specialty.
- Informed consent and the PA's role in the consent discussion
- Scope of practice, supervision or collaboration, and documentation standards
- End-of-life care, advance directives, and goals-of-care conversations in high-acuity surgical patients
- Patient safety, disclosure of complications, and quality-improvement principles
- Newer techniques, devices, and approaches entering cardiovascular and thoracic surgical practice
The "emerging topics" label means you should read current literature and stay aware of how the specialty is changing, since NCCPA lists illustrative subtopics rather than an exhaustive syllabus.
The Second Classification: Cross-Cutting Tasks
The same blueprint also sorts every question by the clinical task it asks you to perform. These eight categories overlay the five domains and are not additional domains or extra percentages. Their weights, like the domain weights, sum to 100% on their own.
| Task Category | Weight |
|---|---|
| History and Physical | 10% |
| Ordering and Interpreting Diagnostic and Laboratory Studies | 20% |
| Formulating a Diagnosis | 15% |
| Health Maintenance | 5% |
| Clinical Intervention | 20% |
| Pharmacotherapy | 20% |
| Applying Scientific Concepts | 5% |
| Legal/Ethical Issues and Emerging Topics | 5% |
Key Takeaway
Three task categories (Diagnostic Studies, Clinical Intervention, and Pharmacotherapy) account for 20% each. When you review any domain, practice all three: what to order and how to read it, what to do procedurally or operatively, and which drug to give, adjust, or avoid.
Notice that the task list repeats a Legal/Ethical Issues and Emerging Topics line at 5%. That matches the fifth content domain, which is a reminder that the two classifications are lenses on a single exam and not two stacked tests.
Exam Format and Logistics
The initial examination consists of 120 multiple-choice questions delivered in two blocks of 60 questions, with 60 minutes allotted to each block. NCCPA delivers it at Pearson VUE test centers. The appointment is allocated about 2.5 hours because it includes a 15-minute tutorial and a 15-minute break on top of the two hours of testing.
- Closed book: personal books, notes, and calculators are prohibited.
- No reopening: once you complete a block, you cannot go back into it, so finish reviewing and flagging within each block before you submit it.
- Fee: $350 in total, made up of a $100 registration/administrative fee and a $250 examination fee. See CVTS Certification Cost 2026: Complete Pricing Breakdown for the full budgeting picture.
- Scoring: NCCPA releases scores after validation, generally eight to ten weeks after administration. A numeric passing threshold and an official specialty-specific pass rate were not verified for this article; for what is and is not known, read CVTS Passing Score 2026: Exactly What You Need to Pass and CVTS Pass Rate 2026: What the Data Shows.
The 60-minute block structure gives you a pace of about one minute per question, which is generous for recall items but tighter for long clinical vignettes. Practice timed sets of 60 so the rhythm feels routine by test day. For scheduling details, see CVTS Exam Dates 2026: Testing Windows, Deadlines & Scheduling.
Sequencing Your Preparation by Domain
Because the domains are weighted so unevenly, your calendar should be weighted the same way, with adjustments for your own gaps. A cardiac-heavy PA should not spend equal time on Cardiac and Thoracic just because that feels balanced. A sensible order is below; the full method is covered in CVTS Study Guide 2026: How to Pass on Your First Attempt.
Thoracic First (Your Likely Gap)
- Start with Thoracic (28%) because it is large and often the least familiar to cardiac-focused PAs
- Work lung cancer staging, pleural disease, esophageal disease, and chest tube management
Cardiac Depth
- Give Cardiac (38%) the longest block: coronary, valve, aortic, heart failure, and arrhythmia
- Pair each condition with its diagnostic study, intervention, and drug therapy
Critical Care and Vascular
- Review hemodynamics, shock, ventilation, and coagulopathy (19%)
- Cover peripheral arterial, aortic, and venous disease (10%)
Legal/Ethical and Integration
- Cover consent, scope, goals of care, and emerging techniques (5%)
- Take timed 60-question sets, then review misses by task category
Ordering Thoracic before Cardiac is deliberate: it forces early attention onto the domain where a typical candidate has the most to gain, while Cardiac gets the largest share of total hours. If your daily practice is mainly thoracic, flip the first two blocks. For a compressed reference to revisit during the final week, use the CVTS Cheat Sheet 2026: One-Page Review of Must-Know Facts.
To gauge how realistic your timeline is, it helps to understand where candidates tend to struggle; How Hard Is the CVTS Exam? Complete Difficulty Guide 2026 goes through that. When you are ready to apply what you have reviewed under exam conditions, work through questions on the CVTS Exam Prep practice test site.
Official Sources and a Weight Conflict to Avoid
NCCPA publishes two preparation resources specific to this specialty. The first is a set of sample questions with critiques (copyright 2021). The second is an optional practice examination priced at $50, with one practice form for this specialty, a 180-day completion window, and educational feedback. NCCPA is clear that practice-exam feedback is educational and does not predict whether you will pass, so use it to find weak areas, not to forecast your result.
Be equally skeptical of commercial question banks that advertise pass rates or guarantees. Those claims are not official exam statistics, and NCCPA does not endorse them.

Frequently Asked Questions
There are five content domains: Cardiac (38%), Thoracic (28%), Critical Care (19%), Vascular (10%), and Legal/Ethical Issues and Emerging Topics (5%). The eight task categories in the blueprint are a separate classification of the same questions, not additional domains.
Cardiac carries the most weight, but the best starting point depends on your background. PAs who work mainly in cardiac surgery often benefit from starting with Thoracic, since it is 28% of the exam and is commonly the less familiar area. Allocate the largest total time to Cardiac regardless.
Use 10%. The content blueprint weights Vascular at 10%, while the older annotations in NCCPA's 2021 sample questions retain a lower figure. The blueprint is the document that defines the exam's content categories.
No. The exam has two 60-question blocks with 60 minutes each, and a completed block cannot be reopened. Review and flag questions inside each block before you submit it.
No. NCCPA lists the five domains as official medical content categories and describes its subtopics as illustrative, not exhaustive. Use the domain names and weights as the framework and expect questions to reach beyond any single list of topics.
Understanding the five domains and the separate task categories gives you a realistic map of what the CAQ-CVTS measures. Anchor your plan to the blueprint weights, shore up the domain where your daily practice is thinnest, and revisit the CVTS exam domains guide as a quick reference while you build your schedule.
