These are your comprehensive MCh Cardiac Surgery level notes on Aortic Stenosis, built directly from six standard textbooks. Here's a quick orientation to what was covered:
What These Notes Cover (17 Parts)
| Part | Topic |
|---|---|
| 1 | Rheumatic Heart Disease - molecular mimicry, Aschoff bodies, Jones criteria, chronic RHD pathology |
| 2 | Full etiology classification - Calcific, Bicuspid, Rheumatic, rare causes |
| 3 | Pathophysiology - Laplace law, Frank-Starling, concentric hypertrophy, progression rates |
| 4 | Clinical features - pulsus parvus et tardus, Gallavardin phenomenon, symptom triad |
| 5 | Investigations - ECG, CXR, Gorlin formula |
| 6 | Echocardiography - 2D imaging, continuity equation, DVI, low-flow low-gradient AS |
| 7 | 2021 ACC/AHA Staging (Stage A through D3) |
| 8 | Natural history - "5-3-2" survival rule |
| 9 | Medical management - why no drugs work, BAV as bridge |
| 10 | Indications for intervention (Class I, IIa, IIb) |
| 11 | Operative approach - CPB setup, aortotomy, annular debridement |
| 12 | Prosthetic valves - mechanical vs. tissue, suturing techniques, root enlargement (Nicks/Manougian/Konno) |
| 13 | SAVR step-by-step |
| 14 | TAVI - valve types, access routes, steps, complications, key trials (PARTNER, Evolut) |
| 15 | Special situations - redo surgery, Bentall, David, Ross procedure |
| 16 | Post-op management - ICU care, anticoagulation, follow-up |
| 17 | Outcomes and prognostic factors |
The three textbook images embedded show: (1) the four types of aortic valve disease by echocardiographic appearance, (2) the complete natural history/pathophysiology/management flowchart from Fuster & Hurst, and (3) CW Doppler differentiation of valvular AS vs. subaortic obstruction vs. HCM.
