DORV.AVSD.Dextrocardia Image – light

  • Dextrocardia [dextro=on the right side]-the heart is reversed and in the right side of the chest (instead of the left).  The lower tip of the heart also points to the right (instead of the left).
  • (DORV) Double Outlet Right Ventricle [outlet=passage for exit, ventricles=lower chambers of the heart] – both vessels (aorta & pulmonary artery) carrying blood away from the heart come out of the right ventricle. (Normally the aorta carries oxygen-rich blood from the left ventricle and the pulmonary artery carries oxygen-poor blood from the right ventricle).
  • (AVSD) Unbalanced Atrioventricular Septal Defect [septum=wall between the chambers of the heart, atriums=top chambers of the heart, ventricles=lower chambers of the heart] – holes in the inner walls of the heart allowing extra blood flow between the atriums and the ventricles. This lets too much blood flow to the lungs and overworks the heart.
  • (PFO) Patent Foramen Ovale [patent=open, foramen=opening] – a hole between the two top chambers of the heart that is covered by a flap.  A cough, sneeze, or strain can cause this flap to open-–letting blood flow where it shouldn’t.
  • (1) Coarctation of the Aorta – [coarctation=narrowing] – a narrowing of the aorta. This decreases blood flow to the body and increases pressures in the heart.
  • (2) Transposition of the Great Arteries [transposition=switch the order, great arteries=the aorta & the pulmonary artery] – the positions of the great vessels are switched so that the aorta (which carries oxygen-rich blood to the body) is closer to the oxygen-poor blood AND the pulmonary artery (which carries oxygen-poor blood to the lungs) is closer to the oxygen-rich blood.  It is usually accompanied by a hole in the wall between the ventricles (ventricular septal defect or VSD).
  • (3) Plumonary Vein Stenosis [stenosis=narrowing of a passage] – a narrowing in one or more of the blood vessels carrying oxygen-rich blood from the lungs to the heart.  This slows down the production of oxygen-rich blood and increases pressures in the lungs.

    This is similar to my daughter’s pre glenn and TAPVD repair heart anatomy.  The differences are:
    Her RV is more developed while the LV is smaller and the remnant of the septum between LV and RV is smaller.  She the common AV-valve in her case works well with only a slight leak.  She has PS and Supracardiac TAPVD as well, and there were 2 veins feeding into the atruim – the VCS and another.

    We have been very blessed that although her CHD’s are severe, she has not had to stay on meds long term, and she is doing pretty well all things considered.  She is 3yrs old now.  She is underweight and her diet is supplemented with pediasure.

  2. Having a child with special needs educates you in a hurry doesn’t it? My 20 y.o. has a VSD but it’s tiny so they always just say to take antibiotics prior to surgery, stitches, or dental work. Otherwise we just keep an eye on it. And pray a lot!

      hello beth my name is sarah im expecting my first baby he will be born in june. he has been diagnosed with dextrocardia with unbalanced avsd i have been looking around all the heart websites and it never makes any sense. how do you cope with your sons heart problame as im asking for advice as i no mothers like you and me ask for help and suport from other mothers. thank you so very much xx

      1. Hey Sarah! I think you can probably get more information from the author of this blog than you can from me. Honestly I had to choose when Josiah was a baby … would I live in terror of what MIGHT happen and try to protect him from any and everything or would I trust that God has each of our days numbered and just enjoy the moments and days and allow my child to live to the fullest. I chose the latter. It hasn’t always been easy but he is a healthy young adult now and a happy one … because he’s been allowed to LIVE his life! Wishing you blessings, wisdom and healing! You can contact me anytime for encouragement and support. I just don’t know if I have any answers! 🙂

      2. Hi, Sarah!
        My daughter was born with both dextrocardia and an unbalanced AVSD. She will be 3 years old in June.
        The AVSD part was very hard for me to understand until someone drew me a picture of it from a different angle. I’ll sketch it for you and post it next week.
        As for advice:

        1 – take life in small (manageable) steps
        2 – expect that things WILL work out in the end and only allow yourself to deal with bad things once they actually happen.
        3 – take care to enjoy the rest of your pregnancy – your heart and lungs are providing for the baby so he is safe inside you…and the doctors will be prepared to help him when he is born.

        It’s scary…but there are many silver linings and deep love and joy ahead of you.
        The CHD Mom community is tight/loving/supportive. You should start a blog of your own. Then reach out to a few blogs and moms in similar situations will find you and support you.
        I’d love to read your blog – so be sure to come back and give me the addy.

        I’d also suggest these 2 links (is it too snooty that one of them is from my own blog??):
        Stef’s a bit ahead of both of us in this journey. Her strength inspires me.

      3. Sarah,
        I just posted a new picture of AVSD–
        This is a cross section of the heart…looking down at the top of the heart. It’s easier to understand AVSD looking at it this way. I hope your pregnancy is going well 🙂
