Escalate
Acute severe mitral or aortic regurgitation with pulmonary oedema or shock, an obstructed prosthesis, or decompensated critical stenosis requires monitored admission and immediate surgical/structural Heart Team assessment; stabilisation must not delay definitive intervention.
Synopsis
Match lesion, timing, anatomy and patient goals to the safest durable valve intervention through a Heart Team.
Symptoms, ventricular response and lesion severity drive intervention; age alone never establishes an indication.
For severe aortic stenosis, NICE favours SAVR in people under 75 who are low surgical risk and TAVI in people 75 or older or at high surgical risk when both are suitable; anatomy, life expectancy and preference can change the choice.
TAVI is offered when surgery is unsuitable and transfemoral anatomy is feasible; surgery remains important for bicuspid anatomy, aortopathy, endocarditis or disease needing concomitant CABG/other valve repair.
Key red flags
Symptomatic severe stenosis
Exertional breathlessness, angina, presyncope/syncope or heart failure with severe valve obstruction warrants prompt intervention review.
Investigation priorities
01
Comprehensive TTEFirst step
Confirm mechanism/severity and ventricular, pulmonary-pressure and multivalve consequences.
Management branches
ASSevere aortic stenosis
Symptoms or another guideline trigger for valve replacement after severity is confirmed.
Exclude a reversible high-flow or measurement explanation and document symptom/ventricular trigger.
If surgery is unsuitable and transfemoral anatomy is suitable, offer TAVI; if TAVI is technically unsuitable, discuss alternative access versus palliation.
Key medicines
Aspirin after TAVI75 mg by mouth once daily when there is no separate indication for oral anticoagulation; use clopidogrel 75 mg once daily if aspirin is not tolerated.
National guidance is shown before implementation-dependent detail. Typical adult dose examples remain subject to patient factors, contraindications and the live BNF or specialist protocol. Source check completed 27 Aug 2026; clinical approval remains outstanding.
