ASCeXAM Cheat Sheet 2026: One-Page Review of Must-Know Facts

TL;DR
  • The 2026 ASCeXAM sits on Tuesday, July 14, 2026, with registration closing May 7, 2026.
  • 200 items across 5 blocks of 40 questions, each block timed at 54 minutes - no carryover time between sections.
  • Physical Principles, Instrumentation, and Examination Principles is the single largest domain, spanning 17 subtopics.
  • Passing is criterion-referenced against a fixed knowledge standard, not a curve against other candidates.

Exam Snapshot: The Numbers You Must Know

Before diving into content, memorize the logistics cold. The National Board of Echocardiography (NBE), a physician-led not-for-profit founded in December 1998 and headquartered in Raleigh, NC, administers the ASCeXAM through Pearson VUE - either in person at one of over 230 Pearson Professional Centers in the US (plus 3,000+ international sites) or remotely via Pearson OnVUE. These figures matter because they shape how you plan travel, testing accommodations, and your final review window.

For a deeper look at how these dates and deadlines fit into your annual planning, see ASCeXAM Exam Dates 2026: Testing Windows, Deadlines & Scheduling. And if you're still confirming whether you qualify to sit for the exam at all, review ASCeXAM Requirements 2026: Eligibility, Prerequisites & How to Qualify before you register.

Break Rule to Remember: The 25-minute pooled break can only be taken between blocks - never mid-block - and unused time from one section does not roll over into another. Budget your pacing accordingly.

Domain Breakdown at a Glance

The current content outline (dated 1/2025) organizes the exam into six domains. Weighting is not evenly distributed, and Domain 1 dominates.

Domain 1: Physical Principles, Instrumentation, Examination Principles

The largest and most heavily tested domain, covering 17 subtopics.

  • Ultrasound physics fundamentals
  • Doppler instrumentation and artifact recognition
  • 3D echocardiography principles
  • Laboratory accreditation standards

Domain 2: Valvular Heart Disease

Stenotic and regurgitant lesion grading, prosthetic valve evaluation, and quantitative Doppler criteria.

Domain 3: Chamber Size and Function

Left and right ventricular systolic/diastolic function, chamber quantification, and normal reference ranges.

Domain 4: Congenital Heart Disease

Adult congenital lesions most likely to appear on echo in a general cardiology or lab setting.

Domain 5: Cardiac Masses, Pericardial Disease, Contrast and New Applications

Tumor versus thrombus differentiation, pericardial effusion/tamponade physiology, and contrast agent use.

Domain 6: Miscellaneous Topics (Role of Echo)

Clinical scenarios testing when and why echo is the appropriate diagnostic tool.

For the full expansion of every subtopic within each of these six areas, cross-reference ASCeXAM Exam Domains 2026: Complete Guide to All 6 Content Areas. If you're trying to gauge how tough this content actually is relative to other board exams, How Hard Is the ASCeXAM Exam? Complete Difficulty Guide 2026 breaks down the difficulty factors in detail.

Physical Principles & Instrumentation Cheat Sheet

Because Domain 1 carries the heaviest weight, your one-page review should devote proportionally more space here than to any other domain. Key facts to have automatic recall of on test day:

  • Ultrasound wave basics: relationship between frequency, wavelength, and axial resolution; higher frequency improves resolution but reduces penetration.
  • Doppler principles: the Doppler equation, aliasing and Nyquist limit, and when to switch from pulsed-wave to continuous-wave Doppler.
  • Artifacts: reverberation, mirror-image, shadowing, and near-field clutter - and how to distinguish true pathology from artifact on a still frame.
  • 3D echocardiography: acquisition modes, spatial vs. temporal resolution tradeoffs, and appropriate clinical indications.
  • Machine settings: gain, compression, dynamic range, and their effect on image interpretation questions.
  • Laboratory accreditation: quality assurance concepts and accreditation body requirements that show up as isolated recall items.

Key Takeaway

Treat Domain 1 as the backbone of your review - if you only have time to master one area cold, this is it, given its 17-subtopic breadth and outsized presence on the item bank.

Valvular Heart Disease Quick Reference

Domain 2 questions tend to be image- or waveform-based, testing whether you can apply quantitative criteria rather than just recite definitions. Must-know reference points:

  • Continuity equation for aortic valve area calculation
  • PISA method for regurgitant orifice area and regurgitant volume
  • Severity grading thresholds for aortic stenosis, mitral regurgitation, and aortic regurgitation
  • Prosthetic valve evaluation - differentiating normal transprosthetic gradients from pathologic obstruction
  • Rheumatic versus degenerative valve disease patterns on 2D imaging

Expect vignette-style stems that pair a brief clinical history with a Doppler tracing or M-mode image, asking you to select the most likely diagnosis or next step.

Chamber Size & Function Fast Facts

Domain 3 leans heavily on quantification formulas and normal reference ranges. Have these locked in:

  • Biplane Simpson's method for LV ejection fraction
  • Diastolic function grading using E/A ratio, e', and E/e'
  • RV function indices: TAPSE, fractional area change, and RV strain concepts
  • Chamber quantification cutoffs by sex-specific normal ranges
  • Strain imaging basics and when global longitudinal strain changes management
Common Trap: Questions in this domain often hinge on recognizing when a measurement technique is technically correct but clinically misleading (e.g., foreshortened apical views skewing Simpson's method). Read image-based stems for subtle geometry cues, not just numbers.

Congenital, Masses, and Miscellaneous Rapid Review

These three domains are smaller individually but collectively meaningful. Don't neglect them in favor of over-studying Domain 1.

Domain 4: Congenital Heart Disease

  • Atrial septal defect types and shunt physiology on color Doppler
  • Bicuspid aortic valve and associated aortopathy
  • Patent foramen ovale versus ASD differentiation with bubble study

Domain 5: Cardiac Masses, Pericardial Disease, Contrast and New Applications

  • Thrombus vs. tumor vs. vegetation - mobility, attachment site, and echogenicity clues
  • Pericardial effusion grading and tamponade physiology (respirophasic flow variation)
  • Contrast echocardiography indications for LV opacification and endocardial border definition

Domain 6: Miscellaneous Topics (Role of Echo)

  • Appropriate use criteria - when echo is indicated versus when it isn't
  • Comparative role of echo relative to other imaging modalities in specific clinical scenarios

Registration and Test-Day Mechanics

Content knowledge alone won't get you through if you mishandle the administrative side. Key mechanics to review before your test date:

  • Eligibility documentation: North American-trained physicians submit a valid unexpired medical license or a notarized Letter of Good Standing from an ACGME-accredited program director; non-North American-trained physicians submit a valid license plus a Medical Council letter or certificate of good standing (dated within 12 months) if their license has no expiration date. All documents must be in English or accompanied by a certified translation at your own expense.
  • Two forms of original valid ID are required at check-in - no exceptions.
  • No calculators or reference materials are permitted in the testing room.
  • Certification levels: Transthoracic (t), Transthoracic plus Transesophageal (te), Transthoracic plus Stress (ts), and Comprehensive (c) - confirm which level applies to your practice before registering.
  • Post-pass obligations: passing physicians must enroll in Maintenance of Testamur in Echocardiography (MOTE) the following January - free the first year, then $85 annually, with requirements due December 31 each year. Recertification exams were discontinued starting July 2024 and replaced by MOCE.
