Coronary Angiography Training

Learn coronary angiography (CAG) by swinging the C-arm and taking the pictures yourself on a live, computed angiogram. Cases from normal coronaries to total occlusion, a 3D coronary atlas, real angiograms for comparison, lessons and quizzes teach you the projections and how to read them. A blood gas trainer — acid–base reading in seven levels — is included free. For physicians, residents, medical students, nurses, radiologic technologists and cath lab staff. Available in 9 languages.

CORONARY ANGIOGRAPHY
An educational simulator for coronary angiography (CAG). Every X-ray image is computed in real time on your device.
• Procedure training: from preparation and the device check to radial puncture and sheath, the guidewire under fluoroscopy, engagement, cine runs, catheter exchange, findings and hemostasis — with “Watch demo” for every step
• Angiography viewer: rotate the C-arm freely (LAO/RAO, cranial/caudal) and inject with a 3D control syringe. Zoom, vessel names, AHA segment numbers and a 3D comparison. Nine cases from normal coronaries to a total RCA occlusion, plus a stenosis maker that places a 50–99% lesion or total occlusion at any segment from #1 to #14
• C-arm explorer: keep the contrast flowing while you swing the C-arm, and watch how each angle changes the coronary view alongside a 3D scene of patient, heart and C-arm
• Compare with real images: real coronary angiograms (anonymized cine runs from a public dataset) side by side with the simulation at the same angle, with expert segment labels in color, and a quiz on recognizing projections
• 3D coronary atlas: a beating, high-resolution 3D heart with coronary arteries and veins. Tap for names and AHA segments, see through the myocardium, show perfusion territories, inject in 3D
• Lessons and quizzes: four lessons (anatomy and AHA segments, standard projections, the procedure, complications) and five quizzes (projection, vessel name, stenosis site, stenosis grade, reading)

BLOOD GAS (FREE)
Acid–base balance in seven levels, each with a lesson and a 5-question quiz:
1. Read the direction from pH
2. Respiratory or metabolic? (the four patterns)
3. From the numbers to a diagnosis
4. The anion gap (calculation, classification, albumin correction)
5. Spot the compensation
6. Put it together with the case (history, vitals, other labs)
7. Mixed disorders by formula (Winter's formula and more)

• Lessons: introduction → figure → key points → step-by-step method → common pitfalls. Figures include the pH scale, lungs vs. kidneys, the four-pattern table, the anion gap as stacked bars, the direction of compensation and the prediction formulas
• Questions: blood gas values on a lab-report style panel with reference-range scales and ↑↓ flags. Case questions show the patient, presentation, vital signs and findings

PRICE
The procedure training up to skin preparation, two viewer cases, the C-arm explorer, the 3D atlas, the first two lessons, the projection quiz and some real images are free (ad-supported). The blood gas trainer is completely free.
PRO, a one-time in-app purchase, removes the ads and unlocks the full procedure training, every case, the stenosis maker, all real images and every lesson and quiz. Restore Purchases brings PRO back on another device.

PLEASE NOTE
This app is for education and training. The blood gas values in the questions were written for teaching and are not data from real patients. The anatomy and angiograms are computed simulations (the real images in “Compare with real images” are anonymized angiograms from the public CARDIAG dataset, Lau et al. 2026, CC BY 4.0).
