- Heart Failure is 40% of the exam and Mechanical Circulatory Support is 30% - together, 70% of every score.
- The exam runs up to 240 questions across four 60-question sessions, with up to 8 hours of answering time.
- Initial exam fee is USD 2,995, plus a USD 400 late fee or USD 500 international surcharge if applicable.
- 2026 registration closed June 28, with the standard exam date set for October 7, 2026.
Exam Snapshot: Format, Fees, Timing
Before diving into content, every AHFTC candidate needs the logistics locked in memory. The Advanced Heart Failure and Transplant Cardiology exam is administered by the American Board of Internal Medicine (ABIM) and delivered at Pearson VUE test centers. It is not a short exam and not a cheap one, so treat both facts as planning inputs, not afterthoughts.
- Format: Up to four sessions, each containing up to 60 single-best-answer multiple-choice questions, for a maximum of 240 questions total.
- Timing: Each session allows up to 2 hours, for up to 8 hours of total answering time. With breaks, the full appointment runs approximately 10 hours, including 100 minutes of scheduled break time.
- Delivery: Closed book, computer-based, with an on-screen calculator supplied - no personal reference materials.
- Fee: USD 2,995 for the initial exam, plus a USD 400 late-registration surcharge and a USD 500 international test-center surcharge where applicable.
- Cadence: AHFTC exams occur in even-numbered years. The standard 2026 exam date is October 7, 2026, and registration for that administration closed June 28.

Domain Breakdown: What's Actually Tested
The AHFTC blueprint is organized into four content domains, and their weighting tells you exactly where to spend your limited study hours. Two domains - Heart Failure and Mechanical Circulatory Support - account for 70% of the entire exam.
| Domain | Approximate Weight | Study Priority |
|---|---|---|
| Heart Failure | 40% | Highest - the single largest category |
| Mechanical Circulatory Support | 30% | Very high - combined with HF, over two-thirds of the exam |
| Heart Transplantation | 25% | High - substantial standalone weight |
| Pulmonary Hypertension | 5% | Lower - narrow but still testable |
Heart Failure (40%)
This domain covers the full arc of heart failure management, from diagnosis and staging through guideline-directed medical therapy, device therapy, and advanced/refractory disease. It is the anchor domain and the one where partial knowledge costs the most points.
- Highest-weighted domain on the exam - master this before anything else
Mechanical Circulatory Support (30%)
Covers durable and temporary MCS devices, patient selection, perioperative management, and device-related complications. Combined with Heart Failure, these two domains make up 70% of your score.
- Second-largest domain - do not treat as secondary in your schedule
Heart Transplantation (25%)
Spans candidate evaluation, immunosuppression, rejection surveillance, and long-term post-transplant complications. A quarter of the exam sits here, making it too large to review lightly.
- Third-largest domain, roughly a quarter of total questions
Pulmonary Hypertension (5%)
The smallest domain by weight, focused on classification and management as it intersects with advanced heart failure and transplant candidacy.
- Lowest weight - review efficiently rather than exhaustively
For the complete content outline within each domain, the AHFTC Exam Domains 2026 guide breaks down subtopics in more detail than a cheat sheet can hold.
High-Yield Topics by Domain
Given the fixed weighting above, here is where question-writing effort likely concentrates within each domain based on the blueprint structure. Use this as a checklist during your final review pass, not as a first-pass learning tool.
- Heart Failure: guideline-directed medical therapy sequencing, decompensation management, hemodynamic assessment, staging systems, and refractory heart failure decision points.
- Mechanical Circulatory Support: device selection criteria, temporary versus durable support decision-making, anticoagulation strategy around devices, and management of device complications.
- Heart Transplantation: pre-transplant evaluation and listing criteria, immunosuppression regimens, rejection diagnosis and surveillance, and long-term complication management.
- Pulmonary Hypertension: classification frameworks and how pulmonary hypertension alters candidacy for transplant or MCS.
Key Takeaway
Because the exam uses single-best-answer questions, expect clinical vignettes that require you to choose the single most appropriate next step - not simply recall a fact. Practice questions in that format, not flashcards alone.
Registration, Fees, and Deadlines
AHFTC registration mechanics are unforgiving on timing. Missing the standard window triggers a USD 400 late-registration surcharge on top of the USD 2,995 initial exam fee, and candidates testing at international centers may see an additional USD 500 surcharge where applicable. For the October 7, 2026 administration, registration closed June 28 - a reminder that these windows close months before the actual test date, not weeks.
A full fee and refund policy walkthrough lives in the AHFTC Certification Cost 2026 breakdown, and the exam-day calendar mechanics are covered in the AHFTC Exam Dates guide.
Eligibility and Scoring Rules
AHFTC is a subspecialty certification layered on top of general cardiovascular training, and ABIM's eligibility chain reflects that:
- Prior ABIM certification in cardiovascular disease
- Completion of required cardiovascular fellowship training
- An additional 12-month clinical AHFTC fellowship
- Program-director verification of clinical competence
- An unrestricted medical license
Scoring is determined by ABIM's absolute passing standard - your result is measured against a fixed content standard, not against how other candidates performed that year. Recent first-time pass rates were strong (98% among 165 examinees in 2024 and 97% among 191 in 2022), but treat that as evidence the exam is passable with proper preparation, not as a reason to under-prepare. A detailed eligibility walkthrough is available in the AHFTC Requirements 2026 guide, and the scoring standard itself is unpacked further in the AHFTC Passing Score guide and the AHFTC Pass Rate 2026 analysis.
Maintenance of Certification After You Pass
Passing the initial exam is not the finish line. Continued certification requires ongoing ABIM Maintenance of Certification (MOC) compliance:
- 100 MOC points accumulated per 5-year cycle
- Completion of the traditional 10-year knowledge assessment
- AHFTC is currently excluded from ABIM's Longitudinal Knowledge Assessment (LKA) option, meaning the traditional point-based and 10-year assessment pathway applies
Key Takeaway
Because AHFTC sits outside the LKA option, budget for the traditional 10-year assessment cycle rather than assuming a continuous low-stakes alternative will be available.
Using This Cheat Sheet in Your Final Review Weeks
A one-page cheat sheet works best when it's paired with a schedule that respects domain weighting rather than treating all four domains equally. In your last several weeks before the October exam date, allocate review time roughly in proportion to blueprint weight: the most hours to Heart Failure, nearly as many to Mechanical Circulatory Support, a solid block to Heart Transplantation, and a light, efficient pass on Pulmonary Hypertension.
Heart Failure Deep Review
- Guideline-directed therapy sequencing and staging systems
- Full-length timed practice blocks on this domain alone
Mechanical Circulatory Support
- Device selection and complication management
- Mixed practice sets combining HF and MCS vignettes
Heart Transplantation
- Listing criteria, immunosuppression, rejection surveillance
Pulmonary Hypertension + Full Simulation
- Quick, efficient review of classification and candidacy overlap
- One full 8-hour timed simulation to build stamina
This tiered approach - heaviest domains first, smallest domain last, and at least one full-length timed simulation before test day - is expanded step-by-step in the AHFTC Study Guide 2026. If you're still calibrating how difficult the exam feels relative to your baseline knowledge, the How Hard Is the AHFTC Exam? guide is a useful gut-check before you commit to a fixed schedule.
Whichever timeline you use, running timed practice sets that mirror the real single-best-answer format matters more than passive review. You can build that stamina and question-pattern familiarity using the full-length practice exams on our practice test platform, which are designed around the same four-domain structure.
Frequently Asked Questions
