Congenital Calculator vs CAGView 冠動脈ビューア

Congenital Calculator is a professional cardiac hemodynamic calculator designed for pediatric cardiologists and congenital heart disease specialists. Built on the Fick principle, it calculates pulmonary and systemic blood flow, vascular resistance, and shunt fractions during cardiac catheterization procedures. Key features: • Qp, Qs, QeP and Qp:Qs ratio — all indexed to body surface area • PVR, PVRi, SVR, SVRi — pulmonary and systemic vascular resistance • Mixed venous saturation using SVC and IVC • LaFarge & Miettinen VO₂ estimation with log₁₀ and −20% variant • 8-point saturation step-up warning for shunt detection • Full PDF report generation with patient data and results • O₂ content calculation including dissolved oxygen (pO₂ × 0.003) For use by qualified healthcare professionals only.

CAGView helps you learn, by moving the model yourself, how the gantry angle in coronary angiography changes what you see. WHO IT IS FOR - Junior residents about to start in the cath lab - Anyone for whom LAO / RAO / cranial / caudal has not become second nature yet - Anyone who wants to be able to say what the spider view is actually for WHAT YOU CAN DO - Drag a coronary model with AHA segment numbers and look at it from any angle - Reproduce 11 standard views with one tap (spider, RAO caudal, LAO cranial and others) - Highlight the branches that open well in the current view - Switch between three renderings: color-coded, realistic, and fluoroscopy - Toggle segment numbers and the cardiac silhouette THE LEARNING PANEL A panel slides in from the left with three short lessons. - Beam - shows where the X-ray tube and the detector are right now, in an axial and a sagittal diagram. It makes the key relationship visible: a view is named after the detector's position, and what is on screen is the patient seen from there. - Foreshortening - calculates how much each vessel is shortened at the current angle, and explains why that matters when you choose a stent length. - Naming - what LAO / RAO / CRA / CAU mean, and the rule of thumb that the LAD opens in cranial views and the LCX in caudal ones. PRIVACY The app has no network features. It collects nothing and sends nothing. No account is needed. PLEASE NOTE This is a schematic for learning. The actual course and branching of the coronary arteries vary between individuals. Do not use it for diagnostic or treatment decisions.
