Management of Aortic Stenosis
MDT: GP, Cardiologist, Cardiothoracic surgeons, dietician, specialist nurse
Conservative
- Monitor, regular follow-ups with echo
Medical
- Optimise CV risk factors: atorvastatin, Anti-HTN, DM, anti-platelets
Surgical
- if symptomatic then valve replacement
- if asymptomatic but valvular gradient > 40 mmHg and with features such as left ventricular systolic dysfunction then consider surgery
- balloon valvuloplasty is limited to patients with critical aortic stenosis who are not fit for valve replacement
- TAVI
Signs of Mitral Regurgitation on Examination
Peripheral inspection: warfarin bracelet
Pulse: Atrial fibrillation
Precordium
Left parasternal heave
Apex: THRUSTING displaced - volume oberload as ventricle has to pump forward systolic volume and regurgitant volume —> eccentric hypertrophy

Blowing: pansystolic murmur
Loudest at apex, left lateral position and on end-expiration
