You are an expert HKMLE tutor helping me ACE the Hong Kong Medical Licensing Examination (Papers 1 and 2). Create a high-yield, comprehensive, beginner-friendly study note for the topic below. You are FULLY AUTHORISED to add any sections, mnemonics, tables, diagrams (text-based), clinical pearls, trap warnings, red flags, drug interactions, trial data, comparisons, flowcharts, quick summaries, or anything else you think will help me ACE this exam. --- DIAGRAM REQUIREMENTS --- If you can generate actual images/diagrams, include them. If not, use clear written descriptions instead of text-based ASCII diagrams. --- REQUIREMENTS --- For each major condition, include: - Definition - Classification (with table where helpful) - Aetiology / Causes (with a BOLD mnemonic) - Pathophysiology (step-by-step, beginner-friendly) - Risk factors (with mnemonic) - Symptoms (with mnemonic) - Signs (with mnemonic) - Investigations (with mnemonic). Provide a prioritised diagnostic algorithm (Bedside → Labs → Imaging). - Management (acute and chronic, with mnemonics for treatment steps). Differentiate standard international guidelines from local Hong Kong Hospital Authority (HA) protocols and Centre for Health Protection (CHP) recommendations. Break down emergency steps into explicit verbal orders. - Complications (with mnemonic where possible) - Prognosis (with mnemonic where possible) --- ADD THESE ELEMENTS THROUGHOUT --- - ⚠️ HKMLE TRAP boxes (Highlight where standard US/UK textbook answers will cause me to lose marks on Paper 1 & 2) - 🏢 HA CLINICAL PATHWAY boxes (Specify default drug formulations, staging systems, or referral pathways used in HK public hospitals) - 📋 CHP STATUTORY NOTIFICATION boxes (Explicitly flag if the condition is a statutory notifiable infectious disease in HK) - 🌏 LOCAL EPIDEMIOLOGY VARIANT boxes (Highlight high-prevalence local variations, e.g., Klebsiella liver abscesses, Recurrent Pyogenic Cholangitis, local Thalassemia/G6PD patterns) - 📋 INVESTIGATION INTERPRETATION boxes (Provide a classic raw data result example—e.g., ABG, CSF, ECG—and its 1-sentence interpretation) - ⚖️ LEGAL & ETHICAL ORDINANCE boxes (Flag relevant local legislation, e.g., Cap. 136 Mental Health Ordinance or mandatory reporting rules) - 📌 QUICK SUMMARY boxes - 🚨 RED FLAGS box - ❓ COMMON EXAM QUESTION box - 🔬 BASIC SCIENCE INTEGRATION box --- REQUIRED TABLES AT THE END --- - ⚠️ DRUG TRAPS table - 📊 NOTABLE TRIALS table - 🧠 MASTER MNEMONICS table - 🔗 CROSS-MODULE LINKS --- TOPIC --- Module 1D: Valvular + Pericardial + Cardiomyopathies + Infective Endocarditis Valvular Heart Disease: - Aortic stenosis (AS) — causes (bicuspid, calcific, rheumatic), pathophysiology, symptoms (SAD), signs (slow-rising pulse, narrow pulse pressure, ejection systolic murmur), investigations (Echo, catheterisation), management (TAVI vs SAVR), indications for surgery. - Aortic regurgitation (AR) — causes (rheumatic, bicuspid, endocarditis, aortic dissection, Marfan), pathophysiology, symptoms, signs (wide pulse pressure, collapsing pulse, early diastolic murmur), management (surgical indications). - Mitral stenosis (MS) — causes (rheumatic — most common), pathophysiology, symptoms (dyspnoea, haemoptysis, hoarseness), signs (malar flush, tapping apex, opening snap, mid-diastolic murmur), management (valvotomy, replacement). - Mitral regurgitation (MR) — causes (rheumatic, myxomatous, ischaemic), pathophysiology (acute vs chronic), symptoms, signs (pansystolic murmur at apex radiating to axilla), management (surgical indications). - Rheumatic heart disease — Jones criteria, prophylaxis (secondary penicillin), HK relevance.
