2. Case History
• 84 year-old woman
• Treated hypertension, prior thyroidectomy.
• Known cardiac murmur
• Preserved autonomy and activity. Asymptomatic
• Recent diagnosis of an adenocarcinoma of left colon
without other malignant location, indication of left
colectomy
• Referred before surgery because of cardiac murmur
• Mid-systolic murmur 3/6, decreased S2
• No signs of congestive heart failure
• Blood pressure 154/60 mmHg
8. Summary of case analysis
• Severe aortic stenosis
Consistency between:
− Aortic valve area < 1.0 cm² and < 0.6 cm²/ m² BSA
− Maximum jet velocity ≥ 4 m/sec
− Mean gradient ≥ 40 mmHg
• Hypertrophied left ventricle with preserved
ejection fraction
• No other cardiac disease
• Asymptomatic
9. What do you advise?
1. Contra-indicate colectomy
2. Perform colectomy with primary anastomosis,
without treatment of aortic stenosis
3. Consider less invasive surgery: resection +
colostomy (Hartmann procedure)
4. Perform balloon aortic valvuloplasty before
colectomy
5. Perform TAVI before colectomy

colectomy
5. Perform TAVI before colectomy
11. Rationale for therapeutic decision
• Abdominal surgery is required since it is the
only curative treatment of colic cancer
• Less invasive intervention limits haemodynamic
stress but impairs quality of life (Hartmann
procedure was the first option of the referring team)
• Risk assessment should take into account:
− The risk of abdominal surgery
− The risk of cardiac complications due to aortic stenosis
− The risk and consequences of treating aortic stenosis before
abdominal surgery
12. Evaluation of the risk of non-cardiac surgery
30-day cardiac death and myocardial infarction
30-day rates of cardiac death and myocardial infarction
Guidelines for pre-operative cardiac risk assessment and perioperative cardiac
management in non-cardiac surgery. Eur Heart J 2009;30:2769-812.
13. Therapeutic options for aortic stenosis
• Low risk of complications of intermediate risk noncardiac surgery
No death or myocardial infarction in a series of 30
asymptomatic patients with severe aortic stenosis undergoing
non cardiac surgery (>75% at intermediate-risk)
(Calleja et al. Am J Cardiol 2010;105:1159-63)
• Treatment of AS before non-cardiac surgery is
considered only in symptomatic patients or for
high-risk surgery
Guidelines on the management of valvular heart disease (version 2012).
Eur Heart J 2012;33:2451-496.
14. Therapeutic options for aortic stenosis
• Risk of aortic valve replacement
− Euroscore I:
− Euroscore II:
10.1%
1.7%
• The only reason to favour TAVI over surgical aortic valve
replacement would be more rapid recovery.
Take into account the risk of TAVI and the need for
antiplatelet drugs.
• Balloon aortic valvuloplasty may be considered in patients
with symptomatic severe AS who require urgent major non-cardiac
surgery (IIbC)
No indication in this case
Guidelines on the management of valvular heart disease (version 2012).
Eur Heart J 2012;33:2451-496.
15. Management of severe aortic stenosis and elective non-cardiac
surgery according to patient characteristics and the type of surgery

16. Therapeutic decision
• Multidisciplinary meeting (anaesthesiologist,
cardiologist, surgeon)
• Decision of left colectomy with primary
anastomosis without prior treatment of aortic
stenosis
• Direct contact with the anaesthesiologist in
charge of the patient
• Specificities of anesthesia
• Choice of anaesthetic drugs
• Cardiac monitoring
• Post-operative care
17. Outcome
• Left colectomy with primary anastomosis
– Invasive arterial blood pressure monitoring using a
radial catheter
– Anaesthesia: hypnomidate, atracrium, desflurane and
remifentanil (short action opioid)
• Stable haemodynamic during anaesthesia
• Extubation at the end of abdominal surgery
• Uneventful post-operative course
• Patient discharged at home. She remains
asymptomatic
18. Take-Home messages
• Aortic stenosis should be carefully evaluated in
elderly patients needing non-cardiac surgery
because of the risk of cardiac complications
• In severe AS, risk stratification should take into
account:

Symptoms
Indication for non-cardiac surgery (vital vs. functional)
The risk of cardiac complications according to the type of surgery
The risks inherent to the treatment of AS
• Intermediate and low-risk surgery can be
performed safely in asymptomatic patients,
provided appropriate anaesthetic management is
planned
