well, what do you know...

yes, yes, it's been over 24 hours since we got home, and i still haven't posted. bad blogger mommy, bad bad blogger mommy. haha

i don't remember mentioning this here, but maybe i did... asher had an appointment in toronto yesterday. echo, ecg, cardiology, and pacemaker clinic. it promised to be a busy and interesting morning.

first up, i met quickly with someone from the CHSS (Congenital Heart Surgeons' Society) for our yearly check-in for the LVOTO (Left Ventricular Outflow Tract Obstruction) study that asher is part of. basically, the CHSS are following kids who, like asher, have issues with blood leaving the left ventricle. quoth i on FB the other day,
i'm amused by the LVOTO study asher is in. hmm... i guess a non-existent left ventricle and absent "outflow tract" would count as an obstruction, right? ROFL (oh, the things i laugh at anymore... LOL)
the study is nothing intrusive. every year i have to fill out a questionnaire and list everything asher's been through in the last year. the CHSS is doing a long-term study, looking at outcomes for kids like asher and others with HLHS and LVOTO defects. (for the record, i enroll asher in every study i'm approached about. selfishly, it's that many more people keeping an eye on my littlest man. but my main reason is this: i believe that we have a responsibility to use everything we have been given - the good and the "bad" - to help others. asher has been given half a heart. and so, when we're appraoched, i enroll him. i pray that the docs and surgeons will find ways to help kids with HLHS and other complex heart defects, so that others will not have to go through what asher has been through. but that's a tale for another day...)

so i met with carol, filled out the form (and noticed how many admissions over the last couple years have been for sepsis... shudder! it's one thing to know, it's a whole other thing to see it written down like that...) and then we went in for the echo.

my mother had come with us. and she was fascinated by the echo, having never seen one before. asher did very well, staying still and quiet for most of it. (and this is why there's a TV in every paeds echo lab. because it's too hard to keep a 4-year-old boy quiet for 45 minutes at a stretch. haha) i watched the echo, too... his heart is so beautiful, so simple, so complex, so scarred, so new... a work of art, truly.

(yes, i do love cardiology. why do you ask?)

then off to the ECG lab. asher put on the leads, with some help from the tech. i looked at the monitor. heart rate: 109 bpm. (remember that number. it's important.) so we got asher to sit still for 10 seconds, the tech printed off the report, and then she asked, still looking at the ECG, "does he have a pacemaker, mom?"

now, some of you might be thinking, "well, duh!!! of course he does!!"... but you should realize, there was no mention of the pacer on the orders. it said, "HLHS." that's it. no mention of the electrophysiological disaster area that is asher's heart. nope. just "HLHS." so she should have had no way of knowing that he had a pacemaker, just by looking at the tracings on her screen.

as i answered, "oh! yeah, he does."... i peaked over her shoulder at the monitor... and saw... a tell-tale spike before the squiggly wave. that spike... is the pacemaker, shocking asher's heart to induce a beat.

remember, asher's heartrate during the ecg was 109.

asher's pacemaker is set at 80.

which means that it should fire when he's beating below 80 bpm, and is supposed to stop pacing when he's over 80.

109 is over 80.

did you catch that??? remember how i've been saying for a while now that there's a problem with his pacemaker? yup. read on, gentle reader, read on.

so we saw dr r, who said that everything looked fine. asher's heart is working well, the muscle is strong and function is good. there is no obvious cause for the fluid retention the other week, but she said that sometimes fontans just need a couple days of diuretics, so it's nothing to be too concerned about. basically, "heart's fine. look elsewhere." no worries, there. kind of a relief.

but i was most looking forward to pacemaker clinic.

and it proved to be interesting, indeed.

we got in to that clinic at 1:00. i spoke with the nurse/tech, outlining my concerns.

  • his heart rate went down to 74 and stayed there for quite a while, and he had pain in his chest radiating down his left arm and into his jaw.
  • his heart rate, whenever checked, is 100. exactly. every. single. time.
  • the pacer spike on the morning's ECG.
she said, "yes, that does seem suspicious, doesn't it?"

she listened!!!!!

so she hooked him up to a monitor, which started showing his current (no pun intended) ECG tracing. "see what i mean?" i exclaimed, "his pulse is 95 and the pacer's firing!"

she looked and was surprised, first, that it would be doing that, and second, that i knew what i was looking at. (she then told me about a new Physician Assistant programme in canada, and she strongly urged me to look into it and specialize in paeds cardio. she even gave me her card so i can let her know if i decide to pursue it, because she's really interested in it, too. but back to asher. haha) she watched the monitor for a moment, waiting to see if it was just a fluke, a momentary firing, or something significant.

it was something significant.

she continued with her pacemaker exam, checking its settings and collecting its data. she showed me that his heart rate is, correctly, just above 80 most of the time, and that his heart rate is elevated appropriately for his age (it looks like it goes up with activity, which is what a heart rate is supposed to do). and she kept looking...

and remembering what i'd said about his heart rate always being 100 whenever it's checked... 

she did a little test.

she unhooked asher from the monitor and took him into the hall. there, she, asher and my mother ran up and down the hall (well, the women ran; asher walked quickly and yelled at them. he was tired and grumpy and wanted to leave). then they came back into the room, and she hooked him back up to the monitor...

and his heart rate was 155, which was
  1. appropriate for an active heart rate in a child his age.
  2. nearly double the pacemaker's setting.
  3. paced.
that's right, you read that correctly.

his heart was beating 155 times per minute, and the pacemaker was prompting the beats.

she went and got the EP fellow.

he looked at the data, and agreed that asher's pacemaker wasn't working the way it's supposed to. "it's too sensitive," he said. so christine fiddled with the settings and made asher's pacemaker work properly.

then she threw in a little bonus: a sleep mode. during the day, asher's pacemaker will keep his heart rate above 80. overnight, from 9:30 to 7:15, it will keep him above 70. when he's sleeping, he doesn't need as many beats, so he can safely go down to 70. this will save the battery, but also allow for better sleep, among other things. 

see, if his pacemaker was keeping his HR artificially high, that could account for a lot of the symptoms asher has been having, including,
  • paleness and grey spells
  • looking flushed
  • irritability
  • chest pain
  • shortness of breath
  • reflux
  • difficulty sleeping
  • loss of appetite
do those symptoms sound familiar? they are CHF symptoms, but they are also what asher has been experiencing over the last few weeks.

do you realize what all this means?!?!

i texted to some friends,
hey! guess what! the pacer was "too sensitive"!!! so she fixed it! which means... there WAS a problem, it DOESN'T need to be replaced, and i'm NOT insane!!!
honestly, i could have cried. it was such a relief to know that i wasn't imagining things, and that, while it sucks that asher's pacemaker wasn't working properly, it was easily fixed. all it took was for someone to listen to me and take me seriously. rather refreshing, i'll be honest.

now, i just want to make this clear: i really like our cardio in london. she is lovely and caring and talks to me as one mother to another. all rare qualities in a doc, and welcome traits, at that. but all this could have been fixed over a month ago, when i first raised the issue. all it would have taken was for her to take asher for a quick run around the clinic for a couple minutes, and maybe a monitor in the room to hook him up to during the tests. honestly, i'm not sure where this leaves us. i can't afford to leave the london clinic and deal solely with toronto; i just can't. yesterday alone cost me the equivalent of one week's groceries. one day. one week's grocery bill. not do-able in the long run. on the other hand...

toronto listens. toronto looks deeper. toronto fixes things.

oh! and in case you're wondering if, indeed, the pacer was the cause of asher's issues lately...

while i'm not a doctor and have no real medical training, i can tell you that his colour is returning (he was already looking better before we left the hospital yesterday), and he's less irritable and eating more. already. he is refluxing less and as i type this post, he is sleeping comfortably upstairs.

just sayin'.

all in all, it was a good day. a long day, but a productive one. i'm "happy" and asher's feeling better.

so, i want to thank everyone who has been praying for asher and this appointment. your prayers were (and are) very much appreciated. and see? prayer works!

66 years ago today...

on 29 November, 1944, Dr Alfred Blalock, Dr Helen Taussig (yes, a woman) and Vivien Thomas (a black man) performed the first Blalock-Taussig shunt operation at Johns Hopkins in Baltimore.

the shunt was designed to help "blue babies," wee ones with a CHD known as Tetralogy of Fallot. in ToF, there are several issues:

  1. pulmonary stenosis. the pulmonary artery carries de-oxygenated (blue) blood from the right side of the heart to the lungs. with PS, the opening to that artery is too small and restricts blood flow to the lungs.
  2. VSD, a hole between the two pumping chambers. this allows blue blood to pass over to the left side of the heart and mix with the red blood and travel out to the body.
  3. right ventricular hypertrophy. the right ventricle has to work harder than usual to overcompensate for the PS and VSD.
  4. overriding aorta. this exacerbates the VSD and allows more blue and red blood to mix and travel to the body.
at this point in history, in 1944, there was no open heart surgery for these babies yet... that would come much later. and actually, up until this day, there was nothing at all that could be done for babies with severely wonky hearts. nothing. this procedure was the first of its kind, anywhere, ever. 

if you're interested in learning more about the surgery, including how to do it, click here. this will take you to a site which will teach you about ToF, and you can do the surgery yourself, in a cyberish kind of way. it's amazing, it really is!

this procedure is not what Asher had. Asher had a modified (or reverse) BT shunt, which went from his MPA (main pulmonary artery, right before it branches off to the lungs) to his proximal innominate artery, allowing most of the blood to by-pass his lungs and go out to his body.

but without this first procedure 66 years ago, Asher would never have survived beyond his diagnosis. there would have been no hope for him at all. and yet...

here he is.

almost 4.

(and for the record, i know of many people with ToF. you can click on Anniek's blog on the sidebar to read her story. and in addition to Anniek, there are two people at my church with tetralogy: a father and son. yes, the father has it, too. i've met him. he's an adult, and if you met him, you'd never know he has a wonky heart. simply amazing. and when you consider that these people would not be here today without this first surgery so very long ago... awesome. just awesome.)

oh, wow, isn't this fantastic? (the problem with blogs is that you can't hear the sarcasm in my voice)

so, this should be interesting. they're opening a new $100million research centre in hamilton, ontario. they will be researching heart and stroke prevention, diagnosis and treatment. isn't that fantastic??

except for one minor problem.

they aren't researching congenital heart disease. only acquired heart disease.

you'll understand if i'm not thrilled about this. don't get me wrong, i appreciate the need to research acquired heart disease. it affects millions of people around the world every year. but, um... what about the people who have heart disease who did nothing other than be born?? do they not count? or is researching the #1 birth defect not important. in canada, 1 in 70 babies is born with heart disease of one type or another (and there are over 100 kinds, of varying degrees of severity). i guess they don't count.

you can read the article about the reseach centre here. and fyi... i'm planning on writing a few letters about this. to the research centre, the spec and other local news media, the local MPP, the minister of health... because this just isn't right. these kids are overlooked too often. and that's gotta change. grrrr.

the day before surgery...

well, asher and i hit the road tomorrow morning at 5. because your baby having open heart surgery isn't rough enough, you have to be sleep-deprived, as well. lol ah, well. that's why there's a starbucks AND tim horton's in the hospital. and that's why there's foot prints on the floor to lead you to timmy's... because you're so exhausted you can't follow directions. just bright orange footprints. clearly designed by a parent who knows... lol

anyway, i thought i would tell you about another exciting research opportunity we were given today. a cardio fellow called this afternoon, and apparently they're studying bloodflow in collateral vessels before and after the fontan. asher will go in for an MRI before the surgery, and from there he will be taken to the OR for his fontan. what an exciting opportunity this is, for asher to be involved in furthering our knowledge of these complex little hearts and helping to develop new strategies and treatments which could keep kids like asher alive.

in the meantime, in 12 hours, asher will be in the OR. and i will be sitting in the waiting room, staring at the door and praying that dr c doesn't walk in for several more hours. so please remember us tomorrow in your prayers/good vibes/positive thoughts/whatever you do. thanks so much! :)
