Cardiogenic Shock
Overview Cardiogenic shock is a life-threatening clinical syndrome in which cardiac dysfunction causes inadequate cardiac output and tissue hypoperfusion. Hypotension is common but is not essential; patients may initially maintain blood pressure through marked vasoconstriction while organ perfusion deteriorates. 1 Acute myocardial infarction is a major cause, but cardiogenic shock may also complicate acute or…

Conjunctival Disease (Conjunctivitis)
Overview The conjunctiva is a thin, translucent mucous membrane that lines the posterior surface of the eyelids (palpebral conjunctiva), reflects over the anterior sclera (bulbar conjunctiva), and forms the superior and inferior ciliary junctions (fornices) up to the corneal limbus. Conjunctival diseases encompass a wide spectrum of infectious, allergic, inflammatory, degenerative, and autoimmune conditions. Among…

Chronic Exertional Compartment Syndrome (Exercise-induced Compartment Syndrome)
Overview Chronic compartment syndrome (also known as chronic exertional compartment syndrome or exercise induced compartment syndrome) is an exertional condition in which repetitive activity causes transiently elevated pressure within a closed myofascial compartment, leading to ischemic pain, tightness, and sometimes neurologic symptoms that predictably begin with exercise and abate with rest. It most often affects…

Enteropathic Arthritis
Overview Enteropathic arthritis is a subtype of spondyloarthropathy associated with inflammatory bowel disease (IBD), particularly Crohn’s disease and ulcerative colitis. It affects up to 20% of IBD patients, with a variable presentation involving axial and/or peripheral joints. The arthritis may run parallel to intestinal disease activity or occur independently, often with enthesitis or dactylitis. It…

Blount’s Disease
Overview Blount's disease, also called tibia vara, is a developmental growth disorder of the posteromedial proximal tibial physis. Asymmetric growth produces progressive genu varum centred below the knee, commonly with procurvatum, internal tibial torsion and relative shortening. It differs from physiological bowing because the deformity persists or progresses rather than following normal spontaneous correction.¹,² Early-onset…

Spermatocele
Overview A spermatocele, or spermatic cyst, is a benign fluid-filled cyst arising from the epididymis, usually near the upper pole of the testis. It commonly contains clear or milky fluid with spermatozoa. Most spermatoceles are painless, discovered incidentally and do not require treatment. Epididymis: coiled structure behind the testis that stores and transports sperm. Spermatocele:…

Aneurysm
Overview An aneurysm is an abnormal localised dilatation of a blood vessel with at least 50% increase in diameter compared to its normal diameter. It is seen more often in arteries compared to veins. Aneurysms are usually asymptomatic until they are very large or they rupture. A ruptured aneurysm can cause massive bleeding and death.…

Anatomy of the Hip Joint | Capsule, Muscles & Clinical Relevance Explained
Learn the detailed anatomy of the hip joint in this concise medical video, covering the hip joint capsule, key muscles including iliopsoas, gluteals, and short external rotators, and relevant clinical conditions such as hip dislocations, vascular necrosis and examination techniques. This video is ideal for medical students, physiotherapists, orthopaedic trainees, and anyone studying musculoskeletal anatomy.…
Charcot – Marie Tooth Disease
Learn about Charcot-Marie-Tooth disease, a hereditary neuropathy that affects peripheral nerves, leading to muscle weakness and sensory loss. This video covers its genetic basis, clinical features, progression, and current approaches to diagnosis and management.
Immunology Map III – T cell development I
Understand the early stages of T cell development, from progenitor cells in the bone marrow to maturation in the thymus. This video explains key processes like positive and negative selection that shape a functional and self-tolerant T cell repertoire.
Our mission
Medical science is complex. Understanding it should feel possible.
Armando Hasudungan turns difficult medical science into clear visual explanations and connected learning experiences—so learners can see the whole picture, remember what matters and find a clearer way forward.
See it clearly
Turn abstract processes and invisible relationships into something the learner can picture.
Connect the pieces
Build understanding around how concepts fit together—not a pile of isolated facts.
Make it useful
Help learners move from explanation to recall, revision and the next logical step.
What clarity feels like
When the topic stops being a blur.
Learners do not come back because the subject became easy. They come back because the explanation gave them a picture they could work with.
“Armando's teaching style gives me the foundational knowledge.
Jessica Payne-Burnett
Medical Student, Charles Sturt University
“The notes I make during his videos help me retain everything better.
Ayesha RaiStudent, Islamabad Medical and Dental College
“The drawings are amazing and super easy to remember.

Coming soon: the AH study platform
The explanation is only the start.
The free library helps you find a clear explanation. The AH platform is being built to help you connect the resources, follow a clearer path and check what actually stuck.
- Watch in a focused, ad-free study environment.
- Move between connected videos, notes, diagrams and questions.
- Know what belongs next instead of rebuilding the study path yourself.
- Test your understanding while the topic is still fresh.
New and worth a look
Keep building the picture.
Femoroacetabular Impingement Syndrome
Overview Femoroacetabular impingement syndrome (FAIS) is a motion-related clinical disorder of the hip in which symptoms and clinical signs occur in association with characteristic femoral and/or acetabular morphology. The accepted diagnostic concept is a triad of symptoms, clinical signs and imaging findings ; bone morphology alone does not establish the syndrome. Patients commonly present with…
