Operative log and credentialing

Cardiothoracic Operative Log and Case-List Preparation for ABTS Eligibility

A practical credentialing workflow that keeps ACGME logs, ABTS operative requirements, pathway distribution, and supporting documentation accurate—without implying that logged cases become oral-exam scenarios.

Key takeaways

  • ABTS operative requirements include both surgical volume and index-case distribution.
  • Residents are expected to use ACGME operative logs to track cases during training.
  • The current public volume standard is an annual average of 125 major operations, with totals determined by program length.
  • Candidates meet one of three pathways—Cardiothoracic, General Thoracic, or Cardiac—and index cases generally require the resident to be primary surgeon.
  • The public ABTS oral exam uses 12 protocols; the operative log supports credentials and is not publicly described as the source of those scenarios.

Credentialing boundary

Know what the case list is—and what it is not

ABTS describes operative experience in two parts: surgical volume and distribution of index cases. An application that does not meet those requirements may be reviewed by the Credentials Committee.

This is distinct from the Part II oral-exam blueprint, which publicly describes 12 standardized cardiac and general thoracic protocols. Do not build a study strategy that assumes the examiner will select the candidate’s logged operations as personal oral cases.

Current public requirements

Understand the published surgical-volume framework

Candidates must use the current operative-requirements pages and application instructions because index categories and credit rules can change. The table above summarizes the public page reviewed July 27, 2026; it is not a substitute for the current candidate portal.

ABTS public major-operation volume requirements
Program typePublished training yearsPublished total
2-year program125 major cardiothoracic cases per year in PGY 6–7250 cases
3-year program125 major cardiothoracic cases per year in PGY 6–8375 cases
6-year integrated program125 major cardiothoracic cases per year in PGY 4–6375 cases

Index-case distribution

Reconcile the operative pathway before the application window

Cardiothoracic pathway

A broad pathway requiring the specified operative numbers to be met entirely within that pathway during the relevant years.

General Thoracic pathway

A pathway emphasizing general thoracic index distribution while still leading to the single ABTS thoracic-surgery certificate.

Cardiac pathway

A pathway emphasizing cardiac index distribution while still leading to the same ABTS certificate.

Primary-surgeon definition

ABTS states that index cases are defined as the resident being the primary surgeon; first-assistant cases do not count unless specifically stated.

Six-step audit

A clean case-list preparation workflow

  1. 01

    Export the current ACGME operative log

    Use the official log rather than a memory-based spreadsheet. Preserve a dated copy before editing or reconciliation.

  2. 02

    Resolve duplicate, miscoded, and missing cases

    Compare dates, procedures, role credit, and case categories against program records while access is still available.

  3. 03

    Map each case to the current pathway requirements

    Do not rely on a prior-year category list. Use the current ABTS index-case documents and application instructions.

  4. 04

    Confirm primary-surgeon credit

    Separate primary-surgeon cases from first-assistant experience unless a current rule explicitly permits credit.

  5. 05

    Review deficits with the program director early

    A late discovery can be difficult or impossible to correct. Document the remediation plan and Board communication when needed.

  6. 06

    Archive the submitted record and confirmation

    Keep the exact final export, supporting documents, submission receipt, and correspondence in a secure professional file.

Documentation quality

Common case-log errors to correct before submission

  • Procedure title does not match the operative role or index category.
  • One operation is duplicated across entries or split inconsistently.
  • Primary-surgeon and assistant credit are not distinguished.
  • A case is entered in the wrong training year or outside the required pathway window.
  • A combined operation is counted in a way not supported by current credit rules.
  • Missing cases are reconstructed without supporting program documentation.
  • The final submission differs from the program director’s reviewed version.
  • The candidate relies on a prior-year requirement document.

Put the framework under pressure

Questions candidates ask

Frequently asked questions

What operative log does ABTS expect residents to use?

The public operative-requirements page states that residents are expected to use the ACGME operative logs during training. It also references an ABTS tracking form when additional information must be provided.

How many major operations are required?

The public page describes an annual average of 125 major operations, with total requirements based on program length. Candidates must verify the current requirement and index-case distribution for their pathway.

Will ABTS ask me about the exact cases in my log during Part II?

The public Part II description presents 12 standardized protocols and does not describe the operative log as the source of candidate-specific oral scenarios.

Source transparency

Official references

Board requirements, dates, and candidate instructions can change. Confirm current details directly with ABTS and the Board’s candidate portal.
