I need a new what?

As I write this, I am a 67 year old man recovering from open heart
surgery to replace my Aortic Valve. I lived most of that time
getting regular medical checkups with no indication I had a
developing problem, and only the broad indicators for heart disease
-- high blood pressure and high cholesterol, both of which I
controlled with diet, exercise, and medication for half my
life. Then, suddenly, shortly after my 67th birthday a new
doctor observed something my previous doctors hadn't, and began a
medical journey I expect others make as well, and may want to know
what to expect.
Anyone ever tell you you have a heart murmur?
My previous primary care doctor retired around the time I turned 67,
and not long before I was due for a checkup, so after some research
I signed up to see a new one at the same group practice. He
was younger and took more time, and found everything much the same
until that final check of my heart with a stethiscope. He
looked a bit pensive and asked me if anyone ever told me I had a
heart murmur. Not definitively -- my previous doctor
said he might have heard something once years ago, but that it
wasn't clear, and not enough to follow up on. Back in the
present he asked if I had ever had various heart tests. Well,
I had a lot of EKGs in the past 10 years, all in connection with two
inpatient and two outpatient surgeries, and nobody ever told me
there was anything unusual. "I think we should get you an
echocardiogram -- it's a good way to find out what's going on and
fast and non-invasive." Great, my two favorite words to hear
about medical tests.
The echo-cardiogram was basically an ultrasound of the heart.
That's an easy one, you basically just sit there while they rub goop
on you, run over your chest with the ultra sound emitter and sensor,
and note numbers and take images off the monitor. The
technician didn't say much (they never do), but one benefit of my
doctor's practice being absorbed into a major medical system is that
everything goes on line and the patient can look at the
results. That took a couple of days. A lot of figures
about pressure and volume, and some disquieting notes about
calcification, with an overall diagnosis of "Severe Aortic
Stenosis".
That was a shock. I'm not an inactive person. I walk 5
miles a day on the golf course most days in the summer and use a
cross country ski machine in the winter, and also do real cross
country skiing and hike mountain trails. Okay, I had noticed
in recent years that I had to reduce the "drag" on the ski machine
and couldn't go as fast or long as before, but I could still walk
over 10 miles in a day and never felt a chest pain. When my
doctor saw it he translated the results as I had and referred me to
a Cardiologist. Meanwhile I was going right on with my normal
activities, including 5 days of walking a mountain goat golf course
in Colorado springs to be a scorer for the US Senior Open.
I saw one of the cardiologists after that, who went through the
results in detail with me and said I would need a new Aortic
Valve. I knew that, and realized this was likely major
surgery, but had heard there was a less invasive option
available. He told me that was true, but it was new, without
enough data to reliably project longevity, and that as a result they
used it in patients who were too old or too frail to tolerate the
open heart version. He also said they couldn't do either
procedure at our local hospital but recommended two others in their
system, and said I could take some time to think about it, so we set
up an appointment in a month after another tournament and a trip to
Alaska.
In a month, after some reading I was convinced I had to get this
done. The cardiologist wanted to set up an Angiogram, which
would bar me from travel and golf for 2 weeks, so we put it right
after labor day, the last tournament on my schedule.
On to planning a repair
I had heard about Angiograms but never realized exactly what they
did. They run tubes (catheters) into the vein and artery in
a leg and up to your heart to inject dye while they Xray the heart
area to see how it flows through your heart, your coronary
arteries, and the major arteries and veins in that area. One
reason they do this is just to give the surgeon a preview of what
your plumbing looks like, but also to determine whether anything
else is wrong, so that they can fix clogged arteries or other
valve problems in one surgery. My cardiologist is a
specialist at this, so he did a thourough job. The good news
he gave me was that there was nothing else wrong in the
heart. The bad news was that he said my Aortic valve was
really bad, almost blocked. After some discussion we picked
the suburban hospital for the procedure. It wasn't as big or
complete as the one in downtown Chicago, but still had a big
cardiac surgery department and an excellent reputation, and would
make it much easier for me and my wife to get to and from for
appointments and visits. Two weeks later I saw the surgeon.
I wound up going with a young surgeon relatively new at this but
with intensive experience and published articles on the
condition. He went through all the options for repair:
- A Trans-Catheter Aortic Valve Replacement (TAVR). This
is the newer procedure that doesn't require opening your chest
or going on a heart-lung machine. As with the cardiologist
(one thing you discover is that "Cardiology", and "Cardiac
Surgery" are different specialties), he said I was too young and
healthy for this. He was a bit more emphatic, saying that
replacing TAVR valves can be difficult, especially if the
patient is older and frailer by then. Okay, I get it.
- A mechanical valve. These probably last at least 25-30
years. That might be all I'd need (depressing thought),
but there are some problems. First, you need to stay on
strong blood thinners (likely warfarin/cumadin) for life.
I had been there, and found keeping my clotting times in range
difficult. Some people do. Not impossible, but it
would require monitoring every week or two. Mechanical
valves are also hard to replace. If the valve goes bad you
need another round of open heart surgery, and even then getting
the old valve out amid scarring from the first operation can be
tough. They tend to use these in young people who need as
long as they can get to avoid more than 2 replacements, and
people in good shape a bit older than me who are unlikely to
ever need it replaced.
- A tissue based valve. There are 3 types of these, one
basically a transplant of human tissue, which is potentially the
most natural and longest lasting, but requires a good match and
probably anti-rejection drugs so it's rarely done. There
are other types made from animal tissue that are similar.
These don't last as long (15-20 years), but typically can be
replaced with a TAVR valve without a second round of open heart
work.
He recommended the tissue valve, with a plan to do a TAVR if needed,
and in the end what I went with. I went away with a surgery
date in November 3 days after my last planned travel of the year and
a bunch of information for prep.
It's showtime.
Knowing what would happen and when, I set out to do everything I
needed to do in the fall around the house -- clear the leaves from
the roof and gutters, clean all the windows and paint any frames
needing it, mow and mulch all the leaves I could, even put up the
Christmas Lights (but we didn't turn them on in October).
That's because I knew that I basically couldn't do anything with my
arms for 6 weeks after the surgery and likely wouldn't be able to do
things like climb on the roof until next spring. That all
worked out well (and was a familiar routine from my hip
surgeries. I also had a discussion with the doctor about
supportive medical devices, like a walker, raised toilet seat, or
shower chair, and he said probably not. What I really need to
do is make sure I can get up and down from any place I need to
without pushing off with the arms, which I could.
It was an odd feeling going to a conference, talking to friends, and
thinking all the time I was going into a medical procedure with
serious risks and long recovery time 3 days after I returned.
We got a little good news in that my surgery was pushed back from
7AM to 9AM, meaning I could wait until nearly 6AM to make the trip
in. I followed the instructions for discontinuing most of my
medications to the letter (you can't be on blood thinners or various
supplements for 3-7 days before surgery like this because it effects
blood clotting. I took my shower in disinfectant, wiped off
with disinfectant soaked towels, then did all that again at the
hospital before climbing into a gown and a gurney while they hooked
up monitors and IVs.
I've had several rounds of surgery. Normally I remember the
ride to the OR (just like portrayed in various TV dramas, mainly
what you see is the ceiling lights passing overhead), the cold of
the OR, the big team of supporting people, and being transferred to
the table before anesthesia kicks in -- not this time. The
next thing I remember was waking up in a bed and asking "what time",
getting something like 7PM as the answer, later than I
thought. My wife was there and would clearly be spending the
night.
The doctor eventually reviewed what he had done. The procedure
normally takes 4-6 hours, most of that spent in prep and closure,
with only an hour of actual surgery on the valve. That's
basically what happened, but the doctor said my valve was the worst
one he ever saw, and took an extra hour to remove all the deposits
(or "rocks" as he called them). In the end he been able to get
it all and put in a large tissue valve, big enough to do a TAVR
replacement in it twice if it were ever needed. I liked the
sound of that. Both he and the staff cardiologist said I
probably had a condition known as Bicuspid Aortic Valve, which makes
your valve prone to getting fouled with deposits, but that mine was
so bad they couldn't be sure. In any case they said I had had
the obstruction of the valve for a long time.
My wife said I looked dreadful. Probably unavoidable. I
had two chest tubes (both passing thin red fluid), a catheter for
urine, an IV and an arterial connection to monitor pressure and
pulse in my left arm, A nasty large looking "port" in my neck to
take blood samples, and a catheter going to my heart to monitor and
deliver medications. On my chest I had EKG leads and wires
going into my chest connected to a pacemaker "just in case". I
had an oxygen dispenser under my nostrils and had only recently been
taken off a breathing tube. The surgeon, however kept saying I
looked fantastic, as did all the nurses and technicians who saw
me. I guess I was in the Cardiac ICU (normal), and a lot of
people there were being treated for heart failure or attacks, not
surgical recovery, and as a result in much worse shape to tart
with I remember little of that first night -- My wife said
another patient died in the night and the most vivid memories was
the cheery blast of tones that preceded grim announcements of stroke
or cardiac emergencies in various parts of the hospital to summon
doctors and EMTs to respond.
Time to recover.
As I said I've been in the Hospital before and am a firm believer
that you want to get better quickly to get out as soon as
possible. It's not that you don't get excellent care, but
it's tough to sleep with all that activity overnight, and you run
a risk of being exposed to germs your immune system hasn't dealt
with (i.e. while your home is likely much "germier", it contains
bugs your system has been dealing with successfully). That's
a big step starting in the Cardiac ICU. Typical recovery is
apparently something like 5 days, 2 in the ICU and 3 more in the
hospital cardiac ward. My case seemed a bit more like those
Star Trek Episodes where some crew member is at the edge of death
or being transformed into an alien until the doctor finds the
right setting on the medical tricorder, and suddenly all the
damage drops away.
The dropping away process started pretty quick. I was off
the IV pain killers in the morning and could order from the
"Cardicac" menu from the hospital (actually quite broad). I
wasn't feeling up to much originally, partly because of having had
trouble keeping food down in some other surgery (probably just the
wrong anesthetic), and partly because the breathing tube had left
me pretty sore in the neck, but it was nice to eat on my
own. By mid AM they had me up, walking to the door, and back
into a chair, then in the afternoon pulled out the chest tubes and
the heart catheter so I could take a walk around the Cardiac ICU
-- a quadrangle of rooms surrounding a bullpen of nurses,
technicians, and monitors. I made a full circuit, but felt
weak and light headed, but they continued to tell me I was
recovering fine. By now they were talking about getting me
out of the ICU that day, but there were no patient rooms, so I had
dinner, had some more equipment removed, and my wife went home.
Not long after dinner they had a room, and put me in a wheel
chair to get me there. That was a larger, cheerier room,
with less monitoring equipment but still plenty going on. I
managed to call home and let my wife know where I was and even
tried to follow a football game on my phone. Mostly though I
just read, something else my care givers took as a positive sign,
since most patients just zonk in front of TV.
The next day brought more solid food, and more stuff removed, as
well as several walks around the larger patient ward, plus a few
stairs (they told me to go up and I had climbed 3 stairs normally
before the nurse could stop me and said I was only supposed to
climb one, one foot at a time.) It wasn't easy, but it wasn't
difficult either. The doctors were amazed at my progress and said
I'd probably be released the next day, matching the fastest time
out. That was just fine. They did say that the 3rd day
was often the toughest. Actually I think I was a little
ahead of schedule there too, feeling dead tired after my last walk
of the day. I was worried something wasn't working right,
but when I got a chance to look at the results of all those blood
tests they were running it became clear why. My red cell and
hemoglobin levels were so low I could have passed for a
corpse. Probably a consequence of replacing my lost blood
with plasma, and the fact that I lost some the bone marrow that
rebuilds blood to my hip implants, but they were rising.
I thought the 3rd day would be a waiting game, but nope.
They were satisfied I could go home and started preparing for that
early on, removing the remaining equipment. I took my first
shower, set up followup appointments, got instructions and
training on how to get up and down. My wife made it in by
9AM and was there for most of the "release planning", and nervous
when the hospital was engulfed in a shroud of snow. We
figured the snow would be gone by the time I was released, and
mostly were right. By 11AM the sun was shining and I was in
wheelchair headed for the exit. The trip home was more
exciting than planned as another round of snow had iced all the
roads in our home town making it difficult to get to the pharmacy
and pick up the new medications I'd be taking, but I made
it. So far recovery has meant steady progress and no real
concerns, and I rapidly reached the point where I was walking as
long at a time as they want patients to walk after a month, so
yes, it pays to be in shape.
Time to ponder
One thing you have with any surgery, especially open heart, is a
lot of time with limited activity. That's time to think
about things, read, or just binge watch something you always
wanted. In my case one thing I did was read up more on
"Biscupid Aortic Valve", and the more I read the more likely it
looked that this was indeed what I had. It occurred in 2-3%
of birth and ran in families. What it means is that the
valve, which normally has 3 "flaps" which open to let blood out of
the heart and then close against each other to keep it from
flowing back, has two of those flaps joined, restricting how far
it opens and often causing the valve to leak. I know others
in my father's family, including my father, had heart problems
though I don't know exactly what problems. Many with a
Bicuspid Valve. have the valve leak enough at birth or in
childhood to be detected and many have it repaired, but in others,
like my case, the valve seals well enough to not product a murmur
on a stethescope, and other than a somewhat reduced capacity for
exercise the condition doesn't have any symptoms that would cause
someone to seek more elaborate tests to detect. Mainly it
makes you more prone to building up deposits in the artery around
the valve, which eventually constrict the artery or interfere with
the valve opening, as mine did.
It did make me wonder though whether any of the things I
struggled with physically over the years were also related.
I was never any good at intense exercise and quickly developed a
dislike for it. I couldn't imagine "runners high", when
running only made me gasp for breath and want to throw up. I
particularly didn't like exercising in hot weather, and people
would often comment on the fact that I'd quickly get soaked in
sweat if I tried. All that strikes me as a likely
consequence of lowered blood flow. Still it didn't keep me
from discovering that I could enjoy activities that involved
sustained moderate exercise, like hiking trails that weren't too
steep or playing golf on foot (not from the seat of a motorised
cart), and always took the 2-4 flights of stairs to my offices
rather than the elevator. Developing a taste for this
clearly helped me go as long as I did before there was a problem,
but not being athletically talented or inclined was certainly a
factor in my focusing on math, science, and engineering and
largely shunning the normal teenage social life.
So, the bottom line again is make sure someone actually listens
to your heart periodically, especially if any of your blood
relatives has had Aortic Valve trouble, and don't wait to long to
get anything fixed.
