Feeling good with PDA

I am a very active 30 yr. old physical education teacher, aquatic therapist, and aerobic instructor.  I have always had a "murmur," but have had no symptoms of problems with my heart.  About six weeks ago, I noticed a few sharp chest pain, purple nail beds, and decreased aerobic endurance. After wearing a 24 hour monitor, my physician found that my resting heart rate at night is 37 beats per minute. I had an echogram this past week and it was confirmed that I have an PDA.  Is this something that they will simply monitor or is it sometimes fixed with surgery. I sure don't want to "slow down."  Thank you for any information!!

Dear Gina,

The ductus arteriosus connects the pulmonary artery to the aorta and is an important part of the fetal blood circulation.  It normally closes shortly after birth.  A patent ductus arteriosus (PDA) is due to a failure of the ductus to close after birth and occurs in 1 in 2000 people with a female predominance.  Usually with time it will eventually close but by the time someone is in their 30's spontaneous closure is rare.

The risks of a PDA are for infectious endarteritis and a "strain"  on the right side of the heart. For these reasons closure of the PDA is usually recommended.  This can be done either by surgery or with a catheter.  Hope this information helps.

I'm just wondering, is a PDA the same thing as an AP window?  Thanks.

No.  A PDA is a heart maliformation.  An AP window is either referring to a type of view with xray or a type of ENT surgical procedure.
