PEDIATRIC & FETAL CARDIOLOGY · OPENING FALL 2026 IN VISTA, CA
Clear answers about your child's heart.
Care is provided personally by Alexandra Channing, MD - a board-certified pediatric and fetal cardiologist.
Knowledge starts with a thorough evaluation.
- An early, accurate diagnosis can inform care decisions and help you plan next steps with a guided path forward.
- Whether that means clearance for sports and school, necessary restrictions, or a defined plan for ongoing care.
- I perform every evaluation during an unhurried visit, taking the time to explain what I find in clear terms.
- Together, we build a tailored roadmap so you and your child fully understand the findings and what happens next.
If you are expecting, I provide the same guidance and personalized care before delivery.
- If routine screening or a diagnosis has raised questions about your baby's heart, I evaluate your baby before birth and explain what it means and what can be expected.
- There is no referral needed - when the wait for answers is the hardest part, I can often see you or your child within days. Clear, published pricing for every service in our office - no facility fees, no hidden costs.
Common reasons families come to me: fetal echocardiography, congenital heart disease care, a pediatric cardiology second opinion, and chest pain, palpitations, and fainting.
Dr. Alexandra Channing, MD

Meet your physician
Dr Alexandra Channing.
I am a board-certified pediatric and fetal cardiologist. I completed my fellowship training at Children's Hospital of Philadelphia. Most recently, I was an Associate Professor at Columbia University in New York, where I was the director of the Pediatric Marfan & Aortopathy Clinic. Through fellowship training, and the years since spent caring for patients, I developed the expertise on which this practice is anchored. My goal is to give families the personalized attention, time, and care they deserve.
An outpatient direct-care practice based in Vista, serving North County San Diego - including Carlsbad, Oceanside, Encinitas, San Marcos, Solana Beach, and Del Mar.
