Well, after spending ten minutes or so crying in bed tonight, I decided to get up and write about our ultrasound appointment today. Warning: it gets very technical, but I wanted to get it all out there. Hopefully you can follow it. For those who hate to read, I've summarized it all at the end.

The ultrasound technician, who specializes in fetal echo cardiograms, spent twenty minutes scanning the baby's heart, recording everything she did to a videotape. She did different views, measured velocities for different arteries, examined the red and blue flows of blood in and around the heart, and told us baby's heart rate (141 bpm, normal).

Since we were still waiting for the pediatric cardiologist, Dr. Rajan, to arrive from Children's Mercy Hospital, she then taped some ultrasound views of the baby for our videotape collection. She printed off three scans for us, two of the baby's profile (right), and one of the face (left). It was hard to do the profile since baby was facing down and away from us.
Then Dr. Rajan arrived. He and the technician spent the next twenty minutes reviewing the entire tape she made for him. Halfway through, Dr. Scott, one of the OBs on the team, arrived to watch. They discussed things that they saw, reassuring us that they would discuss it all with us after they were finished. Then Dr. Rajan took control of the ultrasound machine, and spent another twenty minutes scanning the heart from all sides. He seemed to be pleased with the view he got coming through the baby's back. But he continually dug the wand deep into my belly, and it began to really hurt.
When he was satisfied, he and the technician stepped to one side of the room to quietly go over the findings. Dr. Scott then took control of the wand and indicated he wanted to do more anatomy scanning. He was looking for the organs of the torso cavity. He showed us the diaphragm and after some searching, finally found the baby's stomach below the diaphragm, as it should be. He was pleased that the cavity was properly positioned and told us so. He said everything about the baby, other than the heart, was in good shape and normal.
All told, we were in the ultrasound room for an hour and twenty minutes. As Tim said, the longer it took, the worse we feared the results.
So then Tim and I left the room to wait for Dr. Rajan in the conference room (where we had last met with Dr. Lu). First to arrive was a young woman who was to be our coordinator between St. Luke's (the hospital I would deliver in) and Children's Mercy (the hospital where the heart surgeries would be performed). She explained her role to us, then sat quietly after Dr. Rajan arrived.


The doctor sketched for us what a normal baby's heart would look like (at left), and what our baby's heart looks like (at right). As you can see from the difference, our baby's heart is missing quite a few things, has holes in places it shouldn't, and is missing holes where it needs them. The diagnosis he gave us was no longer hypoplastic left heart syndrome (HLS), which we had previously been told.
First, an explanation of terms and how the heart works: The top two quadrants of the heart are called
atrium and the bottom two are called
ventricle. The
right side of the heart is drawn on the left above, and the
left side is drawn on the right. The "blue" blood, or oxygen depleted blood enters in the right side of the heart, passes through and out to the lungs via the
pulmonary artery, then returns rich with oxygen to the left side of the heart which pumps the "red" blood out via the
aorta. [FYI: Wikipedia is very helpful in understanding the terms mentioned below.]
First, baby has "
AV Canal Defect with Small Left Ventricle." This diagnosis is made up of the four following issues: (a) "primum ASD" which is atrial septal defect, meaning the interatrial septum (the tissue that divides the right and left atria) has a defect. In the diagram above, the portion missing is the one below the normal "hole in the heart" (or foramen ovale). (b) "common AV valve" which means instead of two sets of atrioventricular (AV) valves, there is just one half on the right side and one half on the left side, working together; in our baby's case, most of the valve is committed to the right ventricle. (c) "VSD" which means ventricular septal defect, a defect in the ventricular septum, the wall dividing the left and right ventricles of the heart. (d) "small left ventricle" which, as you can see in the diagram above, is just a tiny area of the heart that is doing nothing.
Second, baby has been diagnosed with "
Double Outlet Right Ventricle." Although not drawn above, the aortic artery does connect to the pulmonary artery, which means both of the great arteries connect to the right ventricle, the definition of DORV.
Third, the diagnosis concludes with "
Pulmonary Valve Atresia." The valve that would normally open and close with each beat of baby's heart has been permanently sealed off. In the diagram above, you see that the pulmonary artery does exist, is attached to the heart, but there is no access to it, as the valve has sealed.
So when baby is born, they will need to keep the "
ductus arteriosis" open, which allows the body to receive some of the oxygenated blood from the lungs. They will give the baby a prostaglandin by IV as soon as the baby is born. (This ductus otherwise closes within the first ten days, it exists to allow the flow of oxygenated blood which baby receives via the placenta instead of the lungs, which of course don't breathe in oxygen while in utero.)

So how do they fix baby's heart? Dr. Rajan showed us three diagrams. In the first week of life, they will perform surgery on the baby. The first operation is called the "
Blalock-Taussig Shunt" or BT shunt. This is a manmade "ductus arteriosis" to allow the mix of red and blue blood, so baby can get at least 50% oxygenated blood through its system. In the diagram on the right, the yellow shunt is the BT shunt. This operation is done through the baby's side, and is not open heart surgery. Baby will require about ten days of recovery time, and another week or so to assist with feeding. So baby will be in the hospital for about three weeks following the surgery.

The second surgery to be performed, when baby is about five or six months old, is the "
Glenn Shunt." What this surgery does is take the
superior vena cava (the artery carrying the blue blood from the top half of the body), which normally returns to the right atrium, and attach it to the pulmonary artery instead, bypassing the heart and going directly to the lungs. This will now help to bring the oxygen level in the bloodstream to about 75%.

The third operation is called the "
Fontan Procedure." In this surgery, the
inferior vena cava (the artery carrying the blue blood from the bottom half of the body) will now be attached to the pulmonary artery. When this procedure is complete, all systemic venous (oxygen depleted) blood flows directly into the pulmonary arteries, completely bypassing what was the right side of the heart. The heart becomes, in effect, a pump simply to take blood from the lungs and pass it to the rest of the body. This surgery might be scheduled any time when the baby is three or four years old, depending on how well he/she is doing. If the baby is suffering from lack of oxygen, the surgery can be performed even sooner.
The doctor said that at any point, things can go wrong. Baby can get fluid build up, infections, or who knows what else. They don't know the long term outlook for this. A child can suffer from heart failure in their teens, or perhaps when they are older. Our child will require cardiatric care for the rest of his or her life.
He asked us to come in again in six weeks for another fetal echo cardiogram. He said they will perform another one of those after baby is born just to confirm the current findings.
After the doctor answered our questions and left the conference room, the coordinator continued to tell us what to expect. When baby is born, they will in all likelihood whisk baby away from me, bring them to the NICU to stabilize the baby, then transport the baby at
three hours old to Children's Mercy Hospital. I will not get to hold my baby. I will not see my baby while I am recovering for the first 24 hours after birth. This is what makes me cry. Tim will go to Children's Mercy to complete the paperwork there, and then after they stabilize baby, he will be allowed to visit and touch the baby. If I am doing well, St. Luke's might give me "a pass" that allows me to leave a bit earlier and travel the ten minutes to the other hospital to visit with our newborn.
In a few weeks, Tim and I will tour Children's Mercy and see how it is set up and how they handle this whole thing from a parent's perspective. We will also consult with the pediatric cardiac surgeons (they have two). St. Luke's assures us that we can choose to change hospitals and use other surgeons; they will send our records elsewhere. But that is for us to think about later.
I'm sure I missed something, it is now 1 AM, and I've been writing for two hours. We did learn some good things like baby's weight (1 lb 2 oz?) and baby is measuring two weeks ahead.
SummaryThe fetal echo cardiogram lasted over an hour. They diagnosed missing valves, sealed over valve openings, and extra holes in the heart. Baby will require three surgeries: the BT shunt in first week, the Glenn Shunt at 5-6 months, and the Fontan Procedure at 3 years old. Baby will be sent to the other hospital within hours of birth, and we will likely not be able to hold baby at all.
