An instant guide to Valve in Valve procedures for clinicians Quick, clear and concise information about heart valves and Valve in Valve therapy. A guide you wish you always had at your fingertips. About Valve in Valve app was originally developed as a collaboration between the technology company UBQO and Dr. Vinayak (Vinnie) Bapat, Consultant Cardiac Surgeon at St. Thomas' Hospital, London, UK. The team at KRUTSCH reimagined the app, introducing modern design, as well as a novel editing interface for to allow cardiologists to edit cloud-hosted valve data. Valve in Valve app provides information specific for a clinical scenario, quickly and simply. This will help in the planning of and performing a Valve in Valve case. The application navigates the user through important aspects of surgical and TAVR valve design, which are vital for a successful Valve in Valve procedure. The app logically steps through the possible combinations to give the user specific information needed to perform the procedure. Success of a Valve in Valve procedure is based on correct identification of the surgical valve, choosing the correct size of the TAVR valve and its subsequent accurate placement. Surgical valves vary in appearance under fluoroscopy and also in their internal diameter. Similarly TAVR valves differ in their appearances and available sizes. Knowledge about all the surgical valves that have been implanted in the last two decades is minimal but relevant to the Valve in Valve therapy. Users can now familiarise themselves with important design information about surgical and TAVI valves; they can also select the valve and find out which size of TAVR valve could be used and how it is best placed during a Valve in Valve procedure. If the valve type is unknown, the App also guides the user through a series of steps where they can identify the surgical valve type and then use the information available for it. The Valve In Valve app can be used to plan a case and confirm suitability for this procedure and reduces the need to trawl through vast amounts of literature to find information specific to the clinical scenario. The information is also available without the need for an internet connection and will enhance the users understanding of various aspects of this procedure. We hope this will result in improved results and better outcomes for patients. Key features - Design information for multiple types of surgical valve - Sizing information for multiple types of surgical valve - Real life and fluoroscopic images of all the surgical valves - Design information about TAVR valve designs - Sizing information for these TAVR valves - Guides the user through a stepped process to help choose a specific valve, then the size and lastly the important dimensions to plan a Valve in Valve procedure - Image based guidance for the ideal placement of a TAVR valve - Video examples of actual placement of a TAVR valve - Discusses important design considerations in detail to improve understanding of the Valve in Valve procedure
epTools Lite

epTools Lite is a platform for the evaluation of heart rhythm disorders. It is a universal app running on iPad, iPhone and iPod Touch devices. epTools Lite is a free app that contains a subset of the functionality included in epTools. Resources include algorithms commonly used to localize arrhythmia substrates and reference guides to assist in the identification of clinical conditions involving abnormalities of cardiac rhythm. Algorithms are implemented via an intuitive user interface. These algorithms guide the user through a series of questions to arrive at an answer while providing a graphical visualization of their progress and result of their analysis. Use of the save path to image feature allows users to save an image of the current decision path when using many of the decision analysis tools included. These images, which appear in the photo album, may be useful to communicate findings with colleagues. Users may access scientific reference material cited in the app. Many of the reference are available for free or are accessible by subscription holders. Subscribers need only enter journal specific log-in identification once as credentials are stored in iOS. Localization of accessory pathways: Two algorithms are provided (based on Arruda et al and Milstein et al) to assist in the localization of accessory pathways in patients presenting with patterns of manifest pre-excitation on 12-lead electrocardiograms. Localization of atrial tachycardias: Two algorithms are provided (based on Ellenbogen et al and Kistler et al) to assist in the localization of atrial tachycardias in patients presenting with atrial tachycardia on a 12-lead electrocardiogram. Localization of ischemic ventricular tachycardia: Two algorithms are provided (based on Miller et al and Segal et al) to assist in the localization of exit sites for ventricular tachycardia in the setting of single and multiple myocardial infarction based on findings on 12- lead electrocardiograms during ventricular tachycardia. Localization of idiopathic ventricular tachycardia and premature ventricular contractions: A reference is provided consisting of ECG findings for various idiopathic ventricular arrhythmia locations. An algorithm is provided based on Ito et al to assist in the localization of ventricular ectopic activity and tachycardia based on ECG findings. Differentiate endocardial from epicardial ventricular arrhythmias via calculation of the maximum deflection index (Daniels et al). Disease Assessment: A tool are provided to assist in the assessment of Arrythmogenic Right Ventricular Dysplasia/Cardiomyopathy (ARVD/C) . Tools to differentiate SVT from VT using features noted on the 12-lead electrocardiogram are provided utilizing the Brugada and Verckei et al algorithms. Tools to calculate the CHADS₂ and CHA₂DS₂VASc stroke risk as well as QT correction calculators for heart rate (Bazett or Fredericia) are provided. A creatinine clearance calculator (Cockcroft Gault) is provided. Reference examples using the included tools are available on our website (www.busy-being-born.com/examples).
