[|Human|] Hi--my son has ADHD and needs treated. He is 13 years old and we have avoided any medication due to his VSD he has had since birth. He has a small hole that has never closed on its own and Dr. sees him every 2 years to do Echocardiograms and has never seen the need to close the hole. Our pediatrician is wanting to place my son on Vyvanse but im worried as the drug claims you should not take if you have cardiac structual problems as sudden death can result. can you please advise..thanks
[|AI|]  Hello, As you said your son has VSD and your doctor is planning to start Vyvanse (Lisdexamfetamine) for ADHD. If your son is not on any cardiac medications, doesn't get breathless while playing, not having recurrent episodes of chest congestion and pneumonia then probably his VSD is small. Small BSDs with little shunt are often asymptomatic. Moderate to large BSDs result in pulmonary over circulation and heart failure. Approximately one third of all BSDs close spontaneously. Now regarding Vyvanse (Lisdexamfetamine), adverse effects of Lisdexamfetamine related to cardiovascular system are abnormal heart rhythm, high blood pressure, etc. As per your information supposing your son has small VSD which is not causing any pulmonary hypertension and heart failure, taking Vyvanse (Lisdexamfetamine) for ADHD would be safe, and you may trust your doctors' judgement. Hope I have answered your query. Let me know if I can assist you further.
