Cathlas vs IVUSAID

The progress of technology allows for the delivery of a collection of rare and important video images to users in a practical way that cannot be similarly produced via textbooks or peer-reviewed journals. The app is designed to cultivate and integrate contributions from users who would like to add educational images, videos and data that will enrich the knowledge of the interventional cardiology peers community. The moderation and inclusion of images will be processed by experts in the field prior to their publication online. DISCLAIMER: Cathlas has been developed as a reference aid only, and no guarantees are made regarding the completeness or adequacy of the representations shown and information conveyed by the app. The app will not be liable for any claims arising from its use. Please seek a doctor's advice in addition to using the app and before making any medical decisions. This app does not contain any personal information. Cathlas includes angiographic videos in various topics – for example: Anatomy of coronary arteries with focus on coronary anomalies • Coronary angiography videos with corresponding CT images • Explore and learn to recognize complications • Images of congenital heart disease and right heart catheterization hemodynamics • Unique images of coronary bypass grafting and acute coronary syndrome • Left ventriculogram and aortogram • Mechanical valve fluoroscopies – learn to recognize different valves, normal angels of opening and closing • Intracoronary imaging with intravascular ultrasound and optical coherence tomography images • How to recognize device in fluoroscopy • Rare and important incidental findings on fluoroscopy • Structural cases of TAVR, mitral clip, TMVR, Watchman… • Practice your diagnostic skills with set of heart catheterization videos • Explore high-quality heart catheterization images

The IVUSAID App is a free educational mobile application which has been developed to teach medical professionals how to use intravascular ultrasound (IVUS) for PCI guidance based on the current guidelines using our extensive experience and large database of complex coronary cases. Despite the growing body of evidence for clinical benefits of IVUS-guided PCI, IVUS remains underutilized in much of the world including the United States. Challenges in image interpretation and education are among the barriers to widespread adoption of IVUS in everyday clinical practice. Mount Sinai Heart is a global leader within the field of interventional cardiology as well as mobile apps development. The myriad of cases and pathology which are seen in The Mount Sinai Cardiac Catheterization Laboratory make it the perfect center to educate medical professionals within this field. The Key Concepts section of IVUSAID describes principles of IVUS, image acquisition, and concepts of ultrasound behavior in various tissues. The Image Interpretation section of the app has dozens of representative cross-sectional images, videos, and descriptions of plaque types, stent apposition and expansion, artifacts, and more. A short video for each type of lesion or artifact and post-stent findings, in addition to an annotated representative cross section aims to overcome a major limitation of any article or book on IVUS which present a static image, since the actual IVUS pullback is dynamic. Twenty-one complex coronary cases demonstrate IVUS guidance in a variety of patient presentations and lesions including ACS, LM bifurcation, severely calcified lesions and calcified nodules, spontaneous coronary artery dissection, and malapposed stents as well as how IVUS was used to inform treatment decisions. An extensive quiz section helps deliver educational content in a more interactive format where answers are accompanied by detailed explanations and references. We hope that IVUSAID will help techs, fellows, and early-career physicians incorporate IVUS in their daily practice for stent sizing, post-stent optimization, and identification of appropriate treatment strategies.
