The complete codex for
invasive cardiology.

A complete exam-prep and learning app for the RCIS and RCES certifications — and for working cath lab and EP staff. It bundles 177 slide-based lessons, 2,233 practice questions, 239 concept illustrations, flashcards, mastery tracking, and Cardiac Coach, an AI tutor grounded in the same curriculum. Four full-length mock exam forms are written and loaded, and the timed exam-taking experience arrives at launch.

Yes. The curriculum spans both blueprints — RCIS (cath lab hemodynamics, imaging, and procedural work) and RCES (EP studies, device therapy, and arrhythmia management). You pick your track — RCIS, RCES, or both — and the app tailors your study around it. Of the four mock exam forms, two target RCIS and two target RCES; they become available when the timed exam experience ships at launch.

Coach answers by retrieving from the real curriculum — full-text search over the lessons and concept glossary — instead of generating freeform. You can ask it right from a lesson slide or a question you just missed, so it already has the context. When a topic isn't covered, it tells you rather than guessing. It's a study aid, not a substitute for clinical judgment.

We'll publish plans and pricing when checkout opens — we'd rather show you a price you can actually act on than one you can't. What we can tell you now: there will be no tiers and no locked chapters, so whatever plan you pick unlocks the whole curriculum, Cardiac Coach, and all four mock exams once they ship. Join the waitlist and you'll get the details first.

No. Cardiac Codex is an independent study tool and is not affiliated with, endorsed by, or administered by Cardiovascular Credentialing International (CCI) or any other certifying body. Working through the content doesn't guarantee a passing score — it's built to make that outcome a lot more likely.

Soon. Payments are in final testing now. Join the waitlist and we'll email you the moment public checkout opens — you'll be among the first to get in.

Fees are generally non-refundable, including for partial periods, except where required by law. If something has gone wrong on our end, email info@cardiaccodex.com and we'll look at it case by case. Full terms are in our Terms of Service.

Any modern browser on a phone, tablet, or computer — there's nothing to install. Native iOS and Android apps are planned but not released yet, so today you use it on the web. An internet connection is required; there's no offline mode at the moment.

That depends on the plan you pick, and we'll publish the details when checkout opens. What we can commit to now: any one-time pass will state its length up front and will not auto-renew — access simply ends when the term does, and you won't be charged again unless you choose to buy again.

Yes. The curriculum is written against the current CCI blueprints for RCIS and RCES, and we revise it as CCI updates them. Content is under continuous review during beta — if you spot something wrong, there's a report button on every question and lesson, and we'd genuinely like to hear about it.

Not yet as a self-serve option, but this comes up often and we want to support it. Email info@cardiaccodex.com with how many people you're covering and we'll work something out.
