Aortic Stenosis
Overview Aortic valve stenosis is characterised by obstruction of left ventricular outflow, resulting in inadequate cardiac output, decreased exercise capacity, heart failure, and death from cardiovascular causes. Mild to moderate aortic stenosis is usually a symptomatic, but occasionally can be found on routine examination Locations of stenosis – Valvular (common), supravalvular and subvalvular Aortic Stenosis…
View topic ↗Pelvic Inflammatory Disease
Overview Pelvic inflammatory disease (PID) comprises a spectrum of inflammatory disorders of the upper female genital tract, including any combination of endometritis, salpingitis, tubo-ovarian abscess, and pelvic peritonitis. Causative organisms are either sexually transmitted (such as C trachomatis , N gonorrhoeae , Mycoplasma genitalium ) or endogenous vaginal organisms (for example, Bacteroides species) that ascend…

Overview Leukemia is a common malignancy in children and adults that occurs when alterations in normal cell regulatory processes cause uncontrolled proliferation of hematopoietic stem cells in the bone marrow. Leukaemia: Clonal proliferation of hematopoietic stem cells in the bone marrow Acute Leukaemia: Clonal proliferation of hematopoietic stem cells in the bone marrow that develops…

View topic ↗Toxic Multinodular Goitre
Overview Toxic Multinodular Goitre (TMNG) is the second most common cause of hyperthyroidism caused by a long-standing goitre and/or iodine deficiency which results in an increased risk of mutation and consequent TSH-independent autonomic function of thyroid nodules to produce excess thyroid hormones. Common clinical manifestations include hyperthyroidism and a painless thyroid goitre with palpable nodules.…

De Quervain’s Tenosynovitis: Thumb Wrist Pain (Finkelstein Test, Causes, Treatment)
De Quervain’s tenosynovitis is a painful condition affecting the tendons on the thumb side of the wrist, particularly the abductor pollicis longus and extensor pollicis brevis, as they pass through the first dorsal compartment. It commonly develops from repetitive thumb and wrist movements and is often seen in caregivers and new parents due to frequent…
Heart failure with reduced vs preserved ejection fraction – Pathophysiology and treatment
Heart failure explained: learn the causes, symptoms, tests, and treatments for heart failure with reduced and preserved ejection fraction. This video breaks down cardiac output, preload, afterload, contractility, and heart rate—the four determinants of heart performance—and shows how low cardiac output triggers compensatory mechanisms (Frank–Starling, sympathetic activation, RAAS) that can worsen ventricular remodeling. Viewers will…
Pancreas Clinical Anatomy and Physiology
Learn the essential clinical anatomy and physiology of the pancreas, including its endocrine and exocrine functions. This video highlights its role in digestion, glucose regulation, and relevance to conditions like diabetes and pancreatitis.
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.

Student, Neelain University
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.
Lambert-Eaton Myasthenic Syndrome
Overview Lambert–Eaton myasthenic syndrome (LEMS) is a rare autoimmune disorder of the presynaptic neuromuscular junction. It causes impaired acetylcholine release, producing the characteristic triad of proximal muscle weakness, reduced reflexes and autonomic dysfunction. LEMS may occur as a paraneoplastic syndrome—most commonly associated with small-cell lung cancer (SCLC)—or as a non-tumour-associated autoimmune disorder. Neuromuscular junction: connection…
