These latest criteria address 166 separate indications for diagnostic catheterization and 180 clinical scenarios for coronary revascularization. iCath takes each of these indications and reformats them for quick and easy access on your device. iCath is an unofficial supplement to the appropriate use criteria and is not intended as their replacement. Please familiarize yourself with the latest criteria before using this app. HOW IT WORKS: iCath is divided into three sections. 1. Diagnostic – Based upon the 2012 appropriate use criteria for diagnostic catheterization, this section will ask you a series of questions about the presentation or imaging findings of your patient until you ultimately arrive at a recommendation of “Inappropriate”, “Uncertain”, or “Appropriate”. 2. Revascularization – Based upon the 2012 focused update on the appropriate use criteria for coronary revascularization, this section functions similar to the Diagnostic tab, except it will give you recommendations for revascularization. 3. Appendix – The appendix contains valuable tools and definitions of the terms used throughout the appropriate use criteria. iCath was written and designed by Weston Hickey, MD, a cardiology fellow at the University of Oklahoma Health Science Center in collaboration with Marcus Smith, MD and Mazen Abu-Fadel, MD, FACC, FSCAI. The authors have no conflicts of interest or disclosures. ## Key features - Diagnostic catheterization appropriateness assessment - Coronary revascularization recommendations - Access to 2012 appropriate use criteria - Quick question-based recommendations - Appendix with tools and definitions ## Recent user reviews (10 of 13) All indexed reviews: https://appshunter.io/ios/app/icath/id541582015/reviews.md ### 5/5 — Great app!!! *2014-08-13* Easy to use!!
