Understanding Atrial Septal Defect 

At CardioVascular Health Clinic, your heart health matters to us. Our expert team stays committed to providing top-quality, personalized vascular and cardiovascular care for the full spectrum of heart and venous-related conditions, including atrial septal defects.

We recognize that a heart defect diagnosis can be alarming. Still, our experienced team offers state-of-the-art diagnostic tools and innovative procedures to care for your heart and provide the best outcomes possible.

If you or a loved one is living with atrial septal defects, suspect you may have one, or are curious about available treatment options, we are here for you.

Let’s discuss atrial septal defects in further detail, including what they are, their symptoms, and the treatment options available.

What Is an Atrial Septal Defect (ASD)?

An Atrial Septal Defect (ASD) is a congenital heart condition characterized by a hole in the septum, or wall, between the two upper chambers of the heart (atria). 

This hole allows more blood to flow through the lungs and creates more work for the right side of the heart, enlarging it and eventually weakening it. Atrial septal defects can increase the blood pressure in the lungs, resulting in pulmonary hypertension if left undiagnosed and untreated. 

Causes and Symptoms of Atrial Septal Defect

Atrial septal defects develop in utero, so there are no specific links or lifestyle causes, but genetic or environmental factors may play a role in developing them during early development.

Many individuals with ASD are unaware that they have the disorder. ASDs that remain undiagnosed can cause damage to the heart and lungs, shortening an individual’s life expectancy. 

It is a common condition that may not present symptoms until late adulthood. Typical symptoms include

  • Shortness of breath
  • Heart palpitations
  • Fatigue
  • Heart murmurs
  • Swelling in the feet, legs, or abdomen
  • Stroke
  • Migraines

A cardiology specialist will conduct any of several tests to determine whether an ASD is present when suspected. The most common diagnostic tools include a bubble study (resting echocardiogram with agitated saline injection), electrocardiogram (EKG), and chest x-ray.

Atrial Septal Defect Treatment 

It is important to know that for some, atrial septal defect treatment just involves time. Small ASDs may heal on their own, especially during infancy and early childhood. 

Treatment is required for most, especially patients with larger atrial septal defects, and most traditionally, it involves open-heart surgery. 

The good news is that recent technological advancements now offer the possibility of atrial septal defect treatment through a catheter. However, the optimal treatment depends on various factors, including the severity, size, and current impact of ASD on an individual’s overall health.

Our team at CardioVascular Health Clinic is here to help. We specialize in heart conditions and disorders like atrial septal defects and can provide prompt diagnosis and comprehensive treatment options fit for your specific heart health needs.

We use only the latest diagnostic equipment and state-of-the-art facilities to assess your unique situation and determine the best course of action.

I’m about one month out and things are so much better. At my two week evaluation my symptom score had gone from a 27 to a 7, and I’m sure it’s even better now. That speaks volumes. Now that I’m post recovery, there is no incontinence, I go to the bathroom much less and there are no ED side effects like there are with other procedures. In regard to my quality of life, well, I don’t maintain my life based on my proximity to a bathroom anymore.

Blaine P., M.D.
Professional staff working in a beautiful facility with great doctors who sincerely care about their patients. Without Dr. Schmidt's skill, I would have needed heart bypass surgery instead of a stent. Follow-up has been thorough. I can't recommend them highly enough.
LeAnn H.

Dr. Jim Melton and all the staff are fantastic. He is an excellent surgeon and his team is GREAT!!!! I just had surgery at the surgery center, I have only great things to say about my experience. Without him I really don't think I would be here to write this. If you’re looking for a good cardiovascular team, they are a 5 star for sure.

Dr. Parsons and staff are amazing. He truly listened to me from the consult. Staff showed genuine care for my progress post procedure. I had my follow up appointment today so satisfied with results. Blake made me comfortable from the start. He is an activist for uterine fibroids treatment beyond the standard.

Tamara M.

Professional and caring staff. Dr. Smith is very knowledgeable and shows genuine concern for your personal health. I enjoyed the background music in the procedure room, it really adds to the relaxing atmosphere.

David L.

Dr. John Schrader is the most personable doctor we know. He stays on top of my dads health care and is genuinely concerned about his health. We never leave his office with questions. He answers them all. Even questions we don’t think of. Always professional but never cold or bad bedside manner. In our opinion he is THE BEST around.
Thank you Dr Schrader.

I came to Dr. Warren by a self referral for mals when it took me 8yrs 50+ doctors and thousands of dollars spent on no answers. My first visit I was scared I was just going to be gaslighted just like the past however I was pleasantly shocked when Dr. Warren immediately believed me. She took the time to review many disk I had brought from past tests. She never once dismissed me and listened to ever word I had to say. She scheduled one last test to confirm the diagnosis then I was scheduled for surgery right away. Surgery was a success and I can’t thank her and her staff enough. Dr. Warren truly saved my life.

Angie W.

Dr. Garner literally saved my life 18 months ago and I've followed him to his new practice with Cardiovascular Health. He explains things so clearly, listens and is just a very nice person. His staff is great, too! I highly recommend!

Christy G.

The staff, the nurses, and Dr. Parsons were all amazing. Everything was simple and went well – very Bravo Zulu (military phrase meaning "well done"). In addition to the great staff at CardioVascular Health Clinic, the facilities were clean and well maintained. I have no complaints about anything. The whole experience was A1. I would recommend Dr. Parsons to anyone. He made a huge impact on my life.
