Mechanism, memory, and meaning.
Understand diseases
through the
world
PathoSchema® is a visually led medical education platform that explains pathophysiology through striking global analogies, designed to make complex mechanisms clearer, more memorable, and more human.
Every disease becomes a place you can remember.
PathoSchema® by Astavalence® transforms mechanisms into global visual anchors. Learners do not just read about disease; they see the logic of disease through memorable places, systems, structures and landscapes.
The Sundarbans as retinal microvasculature.
A vast maze of tidal channels becomes a way to understand fragile branching retinal vessels: leakage, blockage and loss of flow become easier to picture.

Health systems, rotating into view.
A clinical and health economics atlas for comparing spend, workforce, coverage and burden across countries.

Mechanism is remembered better when it has a human face.
In condition detail, PathoSchema® pairs pathophysiology with curated patient stories, helping learners connect disease mechanisms with lived experience, language, uncertainty and empathy.
Four real crises. One leadership mirror.
Students enter major global health and systems incidents, make difficult decisions, then receive AI-assisted analysis of their leadership under uncertainty.
Radiology becomes an interactive reasoning exercise.
This is the section clinical trainers need to see. PathoSchema does not simply show an image and reveal an answer. It asks learners to describe the film, build differentials, justify imaging features, confirm the diagnosis, then compare their reasoning against a model answer and simulator.
The learner is not given the diagnosis. They must inspect the film and create a structured interpretation.
This mirrors real clinical behaviour: describe clearly, prioritise risk, justify the leading diagnosis and decide what confirms it.
The feedback page turns the case into a teachable moment rather than a right/wrong reveal.
Clinical procedures become visible, stepwise and safer.
PathoSchema’s Procedural Studio helps learners understand the anatomy, sequence, hazards and confirmation steps behind procedures. The aim is not to replace supervised practice. It is to prepare students to think before they touch the patient.
Chest Drain — Seldinger technique
Learn landmarking, pleural access, guidewire safety, dilation, drain insertion and confirmation.
Identify the triangle of safety and choose the correct intercostal space before inserting anything.
Procedural reasoning is not just knowing the order. The learner should explain the anatomy and the harm prevented by each step.
The neurovascular bundle runs beneath the rib. Inserting below the rib risks intercostal vessel injury.
The learner must know how to confirm position, function and early complications.
Make clinical learning impossible to forget.
PathoSchema by Astavalence brings mechanisms, radiology, investigations, procedures, global comparison and leadership simulation into one mobile learning system.
