Monitoring, Survivorship, and Living with Aortic Stenosis

At a Glance

Living with aortic stenosis requires regular echocardiograms and prompt attention to new symptoms. After valve replacement, lifelong follow-up, medication safety, dental care, infection awareness, and emotional support help protect valve function and quality of life.

Living with aortic stenosis (AS) is a marathon, not a sprint. Whether you are currently “waiting” with a native valve or you have already had a replacement, your care involves lifelong monitoring. This process, called clinical surveillance, ensures that any changes in your heart are caught early so that your treatment can be adjusted before problems become serious [1][2].

Monitoring Your Native Valve

If you have not yet had a valve replacement, your doctor will use transthoracic echocardiography (TTE) to track the progression of the narrowing. The frequency of these scans depends on how narrow your valve currently is [1][3]:

  • Mild AS: Scans are typically recommended every 3 to 5 years.
  • Moderate AS: Scans are typically recommended every 1 to 2 years.
  • Severe (but no symptoms): Scans are typically recommended every 6 to 12 months.

It is important to remember that these are guidelines. Your team may recommend more frequent scans if your velocity is progressing rapidly (more than 0.3 m/s per year, though older studies used 0.2 m/s) or if your heart muscle shows signs of thickening [4][5]. Importantly, if your severe AS becomes symptomatic, you should promptly be assessed for a valve replacement, rather than simply scheduling another routine scan.

Life After Valve Replacement

A common misconception is that a new valve means you are “cured” and no longer need cardiology. In reality, all prosthetic valves—whether surgical or transcatheter—require long-term observation to check for complications and ensure they continue to function well [6][7].

The Baseline Scan

After your procedure, you will have a “baseline” echocardiogram. This scan records the “normal” pressure and flow for your specific new valve [8]. In future years, doctors will compare new scans to this baseline. A single high pressure reading isn’t always a cause for alarm; the key is whether that pressure is increasing over time [9][8].

Tissue Valves vs. Mechanical Valves

  • Bioprosthetic (Tissue) Valves / TAVR: These are monitored over time for structural valve deterioration (SVD)—the gradual wearing out of the leaflets.
  • Mechanical Valves: These do not typically suffer from SVD, but they must be monitored for issues like blood clots (thrombosis) or tissue overgrowth.

Medications and Heart Health

Your medication plan after a replacement is tailored to your heart rhythm and the type of valve you received:

  • TAVR Patients: For those without other heart rhythm issues (like atrial fibrillation), current guidelines favor single antiplatelet therapy (usually 75–100 mg of aspirin daily) rather than dual antiplatelet therapy, as it carries a lower risk of bleeding [10][11].
  • Mechanical Valves: These require lifelong treatment with vitamin K antagonists (like warfarin) to prevent blood clots. Direct oral anticoagulants (DOACs) are not currently recommended for mechanical valves [12][13].
  • Bioprosthetic (Tissue) Valves: These may require short-term or long-term antiplatelet therapy depending on your specific surgery and other health factors [14].

Crucial Advice: Do not start, stop, or change doses of aspirin, warfarin, or any DOAC without explicit instructions from your treating team. Carry a medical-alert card stating you have a prosthetic valve and list your anticoagulation regimen.

Protecting Your New Valve: Endocarditis

People with prosthetic valves have a higher risk of infective endocarditis, a serious infection of the heart’s lining or valves [15][16].

  • Antibiotics Before Dental Work: You may be prescribed specialized antibiotics to take before certain dental procedures that involve manipulating gum tissue or the tooth-root area (such as extractions or deep cleanings) to prevent bacteria from your mouth from entering your bloodstream and settling on your heart valve. Antibiotics are not usually required for routine exams. Do not self-prescribe antibiotics; confirm the plan with your cardiologist and dentist [17][18].
  • Daily Hygiene: Excellent daily brushing and flossing is one of the best ways to reduce your long-term risk of infection [19][18].
  • When to Call: If you have a persistent, unexplained fever, fatigue, or night sweats, contact your Heart Team immediately, as these can be early signs of endocarditis [20][21].

Managing “Scan Anxiety”

It is perfectly normal to feel a sense of dread or “scan anxiety” in the weeks leading up to your follow-up appointment. This uncertainty about what the images will show can be taxing [22].

  • Acknowledge the Feeling: Recognizing that this anxiety is a common part of being a “heart survivor” can help reduce its power over you [23].
  • Focus on Function: Remember that the purpose of the scan is to keep you healthy and active. If a change is found, your team has a plan (such as a “valve-in-valve” procedure for some failed tissue valves, though not guaranteed) to address it [24][25].
  • Seek Support: If anxiety interferes with your daily life or sleep, cognitive behavioral therapy (CBT) has been shown to be highly effective for patients managing chronic health concerns [26][27].

Your new valve is a tool that allows you to return to the life you love. By staying diligent with your follow-ups and medications, you are protecting your future health.

Common questions in this guide

How often should I have an echocardiogram for aortic stenosis?
Mild aortic stenosis is commonly checked every 3 to 5 years, moderate disease every 1 to 2 years, and severe disease without symptoms every 6 to 12 months. Your cardiologist may recommend more frequent scans if the narrowing is progressing quickly or the heart muscle is thickening. New symptoms with severe disease should prompt a timely assessment rather than waiting for the next routine scan.
Why is a baseline echocardiogram important after valve replacement?
A baseline echocardiogram records the normal pressure and blood flow for your new valve soon after the procedure. Doctors compare future scans with this result, so a trend of increasing pressure is often more meaningful than one high reading by itself.
Do I still need heart checkups after TAVR or another valve replacement?
Yes. Surgical and transcatheter prosthetic valves both need long-term monitoring because tissue valves can gradually wear out and mechanical valves can develop clots or tissue overgrowth. Regular follow-up helps your team identify changes before they become serious.
What medicines are usually used after a valve replacement?
The plan depends on the valve type and your heart rhythm. People with a transcatheter aortic valve replacement and no atrial fibrillation often take one antiplatelet medicine, usually aspirin 75–100 mg daily; mechanical valves usually require lifelong warfarin or another vitamin K antagonist, while direct oral anticoagulants are not currently recommended for them. Tissue valves may need antiplatelet treatment for a shorter or longer period, so do not change any heart medicine without your treating team's instructions.
Will I need antibiotics before dental work if I have a prosthetic valve?
People with prosthetic valves may be prescribed antibiotics before dental procedures that manipulate gum tissue or the area around a tooth root, such as an extraction or deep cleaning. Routine dental examinations usually do not require antibiotics. Confirm the plan with your cardiologist and dentist, and do not self-prescribe antibiotics.
What symptoms should make me call my Heart Team?
A persistent unexplained fever, unusual fatigue, or night sweats can be early signs of an infection involving a prosthetic valve and should be reported promptly. New or worsening shortness of breath or a noticeable decline in walking ability also deserves timely contact with your Heart Team.
How can I cope with anxiety before follow-up scans?
Feeling anxious before a follow-up scan is common. If scan anxiety interferes with your sleep or daily life, ask your care team about cognitive behavioral therapy, which can help people manage ongoing health-related anxiety.

Questions to Ask Your Doctor

Curated prompts to bring to your next appointment.

  1. 1.Based on my last echocardiogram, am I on a 6-month, 1-year, or multi-year monitoring schedule?
  2. 2.What was my baseline 'mean gradient' immediately after my valve replacement, and how does my most recent scan compare to it?
  3. 3.Since I have a prosthetic valve, what is our specific plan for antibiotic prophylaxis before I see my dentist for a cleaning or procedure?
  4. 4.If I have a bioprosthetic valve, am I a candidate for single antiplatelet therapy (like aspirin), or do I need a different medication for my heart rhythm?
  5. 5.If my valve eventually shows signs of 'structural deterioration' (SVD), what are our options for a future 'valve-in-valve' procedure?
  6. 6.I sometimes feel anxious before my follow-up scans; can we discuss how to manage this so it doesn't affect my quality of life?
