Rotations · Echo · Quick Reference

A reference, never a protocol. The thresholds below are published teaching values framed for recall at the machine — they are not read in isolation and they are not autonomous triggers, and they stay marked as teaching ranges until echo faculty verify them. No local reporting wording, contrast protocol or sedation order appears here, because those are institutional and have to come from the lab.

COCATS requirements

Read live from the active version, by effective date.

COCATS Level I · Minimum experience3 months

Fellows are expected to reach Level I within the first two years.

COCATS Level I · TTEs performed75 minimum
COCATS Level I · TTEs interpreted150 minimum
COCATS Level II · Minimum experience6 months

Fellows are expected to reach Level II during fellowship. Level III is a conversation with the Echo Lab Director.

COCATS Level II · TTEs performed150 minimum
COCATS Level II · TTEs interpreted300 minimum
COCATS Level II · Stress echoes interpreted100 minimum
COCATS Level II · TEEs performed / interpreted50 minimum

100 TEEs are strongly recommended, though 50 is the stated minimum.

Program expectation · Stress echoes directly supervised10 minimum

The program’s own expectation, not a COCATS number.

Severe aortic stenosis

AVA≤ 1.0 cm²

Read with the gradient and the flow state — a small valve area at low flow is not the same finding.

Mean gradient≥ 40 mmHg

Flow dependent. A normal gradient with a small area raises the question of low-flow disease.

Vmax≥ 4.0 m/s

Alignment matters. An underestimate here underestimates the whole study.

Published guideline thresholds, as stated in the program’s Echo Work Guide specification — teaching values, not a local protocol, and not yet reviewed by echo faculty

The clinical contextNever read the study alone

By training year

F1Scan in the morning, read in the afternoon
F2 / F3Pre-read in the morning, read out in the afternoon
TEE (F2 / F3)When no fellow is on dedicated TEE

Allowed and encouraged, for the additional exposure.

Who the Echo Lab Director is. §08 sends Level III discussions to them and no source UTKardio holds names the post.

Logins

What UTKardio will and will not hold.

  • Cerner is an individual clinical login. UTKardio does not store a fellow’s Cerner password and never will.
  • UConcall carries schedules and inpatient and procedure billing. No shared credential was supplied, and none should be.
  • Any future shared credential lives server-side in restricted resources, behind the same permission check as a door code — see the rule in AGENTS.md.

Still needed from the program

Listed rather than guessed. These are the facts this page cannot answer.

  • Faculty reviewEcho faculty review of the thresholds and frameworks on Quick Reference and Clinical Guide. Nothing on either page is verified and neither claims to be.
