Living With a Heart Valve: Follow-up, Infection, Medication and Warning Signs

Living with a heart valve is a lifelong, low effort routine rather than a single event: regular echocardiogram checks, sensible protection against infection, the right medication, and knowing which handful of symptoms deserve prompt attention. When I went home two nights after my TAVR, the procedure itself was the part everyone had focused on. What no one had really spelled out was the rest of my life with the valve, so this is the plain version I wish someone had written down for me.

What follow-up actually looks like

Your new valve is monitored for the rest of your life, mostly with an echocardiogram, an ultrasound scan of the heart. After the early post-procedure checks, this usually settles into roughly one scan a year, at an interval your cardiologist sets. The scan measures how well the valve opens and whether any leak is developing.

The reason for lifelong surveillance is durability. Bioprosthetic (tissue) valves are not permanent: surgical tissue valves last roughly 10 to 15 years, and TAVR valves show good durability to about 5 to 8 years in trials, with longer-term data still maturing ¹. A wearing valve almost always announces itself slowly on these scans long before you feel anything, which means a problem can be planned for calmly rather than met as an emergency. My own follow-up is one appointment and one scan a year, and I have come to think of it less as a medical burden and more as a service interval.

Protecting the valve from infection

The main thing you are guarding against is infective endocarditis, an infection of the heart valve, and the everyday defence is unglamorous: good dental hygiene and telling every dentist and doctor that you have a prosthetic valve. Because a TAVR is a short stay of typically 1 to 3 days ², the day-to-day job of protecting the valve quickly becomes yours at home, not the hospital’s.

Endocarditis is uncommon but serious, which is why it is worth taking seriously: it can be difficult to treat and carries a meaningful risk to life once it takes hold ³. The question of antibiotics before dental work is where guidance genuinely differs by country. Some bodies recommend a single antibiotic dose before certain dental procedures for people with a prosthetic valve, while the National Institute for Health and Care Excellence in the United Kingdom does not recommend routine antibiotic prophylaxis for most dental work, reserving it for specific situations ⁴. What everyone agrees on is that regular dental care and clean skin (treating cuts and avoiding unsterile piercings or tattoos) matter more than any single dose ⁵. I keep a note in my wallet that says I have a prosthetic aortic valve, and I hand it over before anyone comes near my mouth with a drill.

Medication after a valve procedure

For a tissue valve, the medication is usually simpler than people fear. Bioprosthetic tissue valves, including TAVR valves, do not require lifelong warfarin, unlike mechanical valves ¹. The common pattern is an antiplatelet such as low dose aspirin, sometimes with a second antiplatelet for a limited period after the procedure, and then a single antiplatelet ongoing.

Lifelong anticoagulation with warfarin (or a similar drug) belongs to two groups: people with a mechanical valve, and people who have a separate reason to be anticoagulated, most commonly atrial fibrillation, an irregular heart rhythm. Which of these applies to you is a decision for your cardiologist, and it can change over time. The one rule that holds for everyone is not to stop or alter these medicines on your own; if a dentist or surgeon asks you to pause them for a procedure, that should be agreed with your heart team first. You can read more about the differences between valves in types of heart valves.

Getting back to normal activity

The point of a new valve is to give you back the activity the old one took away, and recovery is measured in weeks rather than months ². Most people are walking comfortably within days, building up gradually over the following weeks, and back to ordinary life, gentle exercise, swimming, cycling, and travel not long after.

The sensible approach is to build up steadily rather than test yourself, to keep taking your medication reliably, and to let your body set the pace in the first few weeks. For me the milestone was the hill up to the shops that I had been stopping halfway up for a year: a few weeks after the procedure I walked up it without noticing, which is exactly the sort of ordinary thing a working valve is supposed to give back. The detail of that early period is covered in TAVR recovery.

Warning signs worth acting on

A few symptoms are worth acting on promptly rather than waiting for your next appointment. New or worsening breathlessness, ankle swelling, chest pain, or blackouts can signal a problem with the valve or the heart’s pumping. A very slow or racing pulse is worth noting too: because the valve sits close to the heart’s electrical wiring, some people need a permanent pacemaker after the procedure, needed in about 10 to 20% of cases ¹. An unexplained fever lasting more than a few days deserves particular attention, because it can be the first sign of a valve infection ⁵.

None of these means something has definitely gone wrong. They are simply the signals that shift a symptom from “mention it next time” to “get it checked now”. If you are weighing up what else to raise, the questions worth asking your cardiologist about TAVR is a useful companion to this one.
