Questions to Ask Before Aortic Valve Replacement Surgery
For patients and caregivers heading into a pre-op consult. These 20 questions cover TAVR versus open surgery, mechanical against tissue valves, your own risk numbers, what the hospital stay involves, and what the first weeks at home will require.
The questions
Open any question for the note
Can you walk me through my echocardiogram numbers and tell me in plain terms how severe my aortic valve disease is?
Why ask it
Mean gradient, aortic valve area and ejection fraction are the numbers that drive the whole decision, so hearing them translated tells you whether you are in borderline territory or clearly past the threshold for intervention.
Which of my symptoms should the new valve fix, and which ones are likely to stay?
Why ask it
Breathlessness on exertion and chest tightness often improve quickly, while fatigue caused by anemia, lung disease or deconditioning will not. Separating the two sets expectations, so a technically successful operation is not experienced as a failure.
Why are you recommending surgery now rather than monitoring me for another six or twelve months?
Why ask it
The answer tells you what tipped the balance: a symptom you mentioned, a drop in ejection fraction, a rising gradient, or a stress test result. If the surgeon cannot name the trigger, you have time to think.
What is likely to happen to me over the next few years if I choose not to have this done?
Why ask it
Untreated severe symptomatic aortic stenosis carries a poor prognosis, and hearing the likely course for your own case gives you the comparison point for every risk figure that follows.
Am I a candidate for TAVR, open surgical replacement, or both, and what did the heart team conclude for me?
Why ask it
Guidelines expect a multidisciplinary heart team review. Asking directly reveals whether both options were genuinely weighed or whether you were simply routed to whichever procedure the person in front of you performs.
Mechanical valve or tissue valve: which do you recommend for someone my age, and what am I trading away?
Why ask it
The trade is durability against lifelong warfarin. Making the surgeon state the trade out loud, with your age and bleeding risk in it, keeps a decision you live with for decades from being made by default.
If I get a tissue valve, what is the plan for when it eventually wears out?
Why ask it
This is the lifetime management question, and it matters most under 70. A good answer covers whether a future valve-in-valve TAVR will fit inside the valve you are getting and whether your coronary arteries stay accessible afterward.
Which specific valve model and size do you plan to use, and why that one for my anatomy?
Why ask it
Annulus measurements from your CT scan determine which devices fit, and a surgeon who can name the model and the reason has actually planned your case rather than defaulting to whatever is on the shelf.
Will this be a full sternotomy or a smaller incision, and how does that change my recovery?
Why ask it
A full sternotomy means breastbone precautions for six to twelve weeks, which reshapes driving, lifting, sleeping and childcare. A mini approach changes that timeline, so the answer determines what help you need to line up.
Is anything else being repaired during the same operation?
Why ask it
Aortic valve surgery is often combined with bypass grafts, an aortic root or ascending aorta repair, mitral work or an ablation for atrial fibrillation. Each addition lengthens the operation and shifts your risk, so find out before the consent form.
What is my predicted risk of dying or having a major complication, and what does that number mean in real terms?
Why ask it
Surgeons calculate an STS predicted risk of mortality for nearly every case. Getting the actual percentage, plus the separate figures for stroke, kidney injury and prolonged ventilation, replaces vague reassurance with something you can weigh.
How many aortic valve replacements do you and this hospital do each year, and will you be operating on me personally?
Why ask it
Outcomes track with volume for both surgeon and center, and this is also how you learn whether a fellow or a partner may take part of the case. Ask it plainly and note whether the answer is a number or a deflection.
What is my chance of needing a permanent pacemaker afterward, or of a leak around the new valve?
Why ask it
Conduction block and paravalvular leak are the two complications that most often differ between TAVR and open surgery, and your anatomy and calcium pattern change the odds. This is frequently the detail that decides between approaches.
What is my risk of stroke, and what do you do during the procedure to lower it?
Why ask it
Stroke is the complication patients fear most. The answer should include your individual risk factors and the concrete measures used, from embolic protection devices to how the aorta is handled and cannulated.
Will I need warfarin or another blood thinner, and for how long, and how will my levels be monitored?
Why ask it
A mechanical valve means lifelong warfarin with a target INR range, while a tissue valve usually means a shorter course. Ask now who runs the monitoring, whether home INR testing is an option, and what your target range will be.
What do I need to complete before the surgery date, including dental clearance and imaging?
Why ask it
Gated CT, cardiac catheterization, carotid studies, blood work and a dental exam are often prerequisites, and untreated dental infection is a real endocarditis risk for a new valve. Getting the checklist early keeps your date from slipping.
Which of my current medications do I stop, when exactly, and which do I take the morning of surgery?
Why ask it
Anticoagulants, antiplatelets, diabetes drugs and some supplements each have their own stop window, and getting one wrong can cancel the operation or cause bleeding. Ask for it in writing rather than trusting memory.
How long will I be in the ICU and the hospital, and what will the first two weeks at home require?
Why ask it
You want the realistic picture: breathing tube on waking, chest tubes, wires, the odds of post-op atrial fibrillation, and then who needs to be at home with you once you are discharged.
When does cardiac rehab start, and what follow-up will this valve need for the rest of my life?
Why ask it
Rehab referral should be arranged before discharge, not chased afterward, and every replacement valve needs periodic echocardiograms plus attention to endocarditis prevention. Establishing who owns that schedule stops it from quietly lapsing.
If a decision has to be made while I am under anesthesia, who do you speak to and what have I already put in writing?
Why ask it
Naming your healthcare proxy and filing an advance directive before the date is the one piece of preparation only you can do. Raising it with the surgeon also confirms the document actually reaches your chart.
Getting the Most From Your Pre-Op Consult
Practical guidance for the conversation itself
How to run the appointment
Bring the person who will care for you
Whoever will drive you home, manage medications and enforce lifting restrictions should hear the answers directly. Cardiac surgery consults move fast and patients under stress retain very little of them.
Ask for the numbers in writing
Request a copy of your echocardiogram report, your CT measurements and your calculated surgical risk score. Written numbers are what allow a second opinion to comment on your case, and asking for them is entirely routine.
Get a second opinion at a high volume valve center
Unless you are in the hospital and unstable, there is usually time. Centers doing hundreds of valve cases a year will tell you if a different approach or valve type suits your anatomy better.
Split the conversation across two visits
Use the first visit for the decision itself, TAVR versus open surgery and which valve. Save logistics, medications and recovery planning for a second visit or a call with the nurse coordinator, who often has more time than the surgeon.
Numbers to write down before you leave
- Mean gradient across the valve and aortic valve area in square centimeters
- Ejection fraction, and whether it has changed since your last echo
- Your predicted risk of mortality percentage, plus the separate stroke risk figure
- Annulus diameter from your CT scan, and the valve model and size planned
- Estimated ICU nights and total hospital days
- Your chance of needing a permanent pacemaker
- Target INR range and who monitors it, if you are getting a mechanical valve
- Expected weeks of lifting and driving restriction
- The direct phone number for the nurse coordinator or surgical office
Mistakes patients make here
Assuming the less invasive option is automatically the better one
A catheter procedure with no breastbone incision sounds obviously preferable, but durability data, pacemaker rates and future access to your coronary arteries all matter more if you have decades ahead of you. Ask for the comparison rather than the intuition.
Choosing a valve without asking about the second operation
Patients in their fifties and sixties often pick a tissue valve to avoid warfarin without confirming that a future valve-in-valve procedure will physically fit. Raise lifetime management at the first consult, not after.
Leaving dental work until afterward
Bacteria from an untreated tooth can seed a new prosthetic valve. Most programs want dental clearance before surgery, and skipping it either delays your date or leaves a real endocarditis risk in place.
Underplanning the first three weeks at home
After a sternotomy you cannot lift a full kettle, pull open a heavy door or drive. People arrange a ride home and nothing else, then discover they need daily help with basics.
Worth looking at
- The Society of Thoracic Surgeons risk calculator, and any public outcomes reporting available for the hospitals you are considering
- The current ACC and AHA guideline on valvular heart disease, which your cardiologist can point you to
- Patient information from your own program on anticoagulation and home INR testing, if you are getting a mechanical valve
- Your insurer's list of in network cardiac rehabilitation programs, checked before surgery rather than after
