That's the complete guide. Here's a quick orientation to help you use it:

How to Use This Guide

For Valvular Heart Disease, the organizing principle is simple:
  • AS and MS = Stenosis = obstruction upstream → pressure overload
  • AR and MR = Regurgitation = volume leaks back → volume overload
  • Investigations follow the same sequence every time: ECG → CXR → Echo (always key) → Cath if needed
  • Surgery/intervention is indicated when symptoms appear OR LV starts to fail (measured by EF and dimensions on echo)
For DCLD, the central concept is:
  • Portal hypertension + splanchnic vasodilation → RAAS activation → all complications flow from this
  • The 6 major complications each have a specific trigger, test, and targeted treatment
  • Albumin is the common thread across ascites (post-LVP), SBP (alongside antibiotics), and HRS (with terlipressin)
  • Liver transplant is the only definitive treatment for all complications
Key numbers to memorize:
  • SAAG ≥1.1 = portal hypertension
  • Ascitic PMN >250 = SBP (treat before culture results)
  • Spiro:Furo ratio = 100:40 (2.5:1)
  • Lactulose target = 2–3 soft stools/day
  • Transfuse to Hb 7–8 in variceal bleed (not higher)
