Wow! What a day! Overall, we are thrilled with Rebekah's cath and so pleased with what Dr. Baker was able to do. He found two narrowed areas, one at each end of Rebekah's left pulmonary artery (LPA). (The conduit that was put in during the Truncus Repair is functioning as Rebekah's pulmonary artery. Her left pulmonary attaches to her left lung at one end and attaches to the conduit at the other end. She is missing her right pulmonary artery.) The narrowing at the lung end of the LPA is a narrowing of tissue, and Dr. Baker was able to balloon that open a bit more. The narrowing at the conduit end of the LPA is a narrowing in the muscle of the heart itself. That cannot be ballooned or stent-ed (is that a word??). In order to expand the LPA on the heart end of the conduit, Rebekah will need open heart surgery. To further complicate matters, the location of the LPA on the conduit is very, very near to Rebekah's graft valve that is functioning wonderfully right now. Potentially, any surgery on the heart muscle in that location has the possibility of damaging that valve and causing it to leak. With Rebekah's already high pressures, that would be very, very bad.
SO....do we have a plan yet? Well, tentatively we do. Dr. Baker (cath doctor) would like to see Rebekah make it another six months (at minimum) with the ballooning and an additional medication. The pressures in Rebekah's heart are still high, and while the ballooning was good, it did not resolve the problem. The bottom line is that Rebekah WILL need open heart surgery sometime within the next year. The exact timing of that surgery will largely depend upon how the new medication works in lowering her pulmonary hypertension, and how long her heart tolerates the added stress and continues to remain "happy."
Dr. Baker believes (and so do we!) that Rebekah's case is too complex for his decision alone. Sometime in the next week or two, he will be presenting Rebekah at conference. This is a meeting of all of the cardiac docs, the cath docs, Dr. Bradley and his partner (I can't remember his name), and anyone else directly involved in the management of these heart babies. That is why I say the plan we have right now is tentative. After reviewing the results of the cath lab, Dr. Bradley could make changes, opt for an earlier surgery date, or change the plan altogether. If there are any changes made, we should hear about them in a couple of weeks.
As for the medication that Rebekah will be taking, it is Sildenafil, a drug originally marketed for reducing pulmonary arterial hypertension (exactly what Rebekah has!). Most of you will recognize the drug by the name Viagra, marketed for something completely different. There are relatively few side-effects, and a relatively low occurrence of those side-effects when used as originally intended. As Dr. Baker said, when playing in this game, the question is not, "Does it have side-effects?" but rather "Do the benefits outweigh any potential risks/side effects?" The cardiologists believe that in Rebekah's particular case, the Sildenafil has a good chance of lowering Rebekah's hypertension enough to buy us a few more months before she will need surgery again.
As of tonight, Rebekah is still fighting fevers. She was fever-free this morning, and remained fever-free during her cath. However, she flirted with a low-grade fever off and on in the recovery unit, and her fever began climbing again around 8:00 this evening. Rebekah's nurse, Christie, checked her temperature a little while ago, and it was 101.9 after Rebekah had been given Tylenol just a little over an hour earlier. This is definitely not the trend we want to see! A low-grade fever could be attributed to teething, but we are getting high enough that there is concern that something else might be going on. We would love to blame the fever on anesthesia; after all, Rebekah ran fevers for a week after her last open heart surgery. However, the fact remains that Rebekah had a fever last night prior to her admission. We are currently waiting for the attending to give us some input and direction. It is possible that they may draw labs, test for flu, and/or give another dose of antibiotics as an immune system booster. I am praying that Rebekah rests well tonight, despite the fever. She was up frequently last night, and so were we!
So, please keep us all in prayer tonight and tomorrow. Obviously, we would like to get back home tomorrow, but not if Rebekah still needs to be here. The last thing we want to do is go home tomorrow and have Rebekah's temperature shoot up and be sent back in "emergency" status. Please pray for wisdom for the doctors so they will be able to figure out what is going on.
