We collaborate with cardiologists, anesthesiologists and surgeons to provide your child not only the best care but the best recovery after surgery.
The Hopkins heart center was our ‘home away from home’ in a very difficult time. The COVID pandemic was new for everyone, and staff were getting new rules and regulations by the minute. I was impressed with their composure while they cared for Bennett as if it was just a routine procedure during a routine time.
- Megan Gorsuch,
parent of 21-month-old Bennett Guerra, who underwent surgery for tetralogy of Fallot and pulmonary stenosis.
Our experience with Johns Hopkins Heart Center has been nothing short of phenomenal. From the pre-op coordination, to the day of surgery, to the follow up afterwards, everything was great. We honestly wouldn't change a thing and will be forever grateful for everything you did for our daughter and family.
- Laurie and Mike Rosen,
parents of four-year-old Ruby Rosen who underwent surgery to repair atrial septal defect.
When it was time to seek surgical intervention, we were committed to finding the best surgical team. We met with Dr. Mettler and were confident that him and his team were the best - and they proved to be. From initial contact to discharge, the level of care, compassion, and commitment the Heart Center had for our son’s well being was simply outstanding.
- Gypsy and Brian Roberts,
parents of two-year-old Archer Roberts who was diagnosed with critical aortic stenosis at birth.
While at Johns Hopkins Heart Center, we received comprehensive and compassionate care throughout a very stressful and overwhelming time. Each interaction with medical personnel and staff was positive. We could not have asked for better care for our son.
- Erin and Matt McClure,
parents of 7-month-old Hayes McClure who underwent surgery to correct a ventricular septal defect on August 18, 2020 at 3 months old
Reid Thompson is the reason we wanted to meet with the surgeon. His thoroughness and compassion during our fetal echo was amazing. After meeting the surgeon, we knew Hopkins was for us! The medical staff became our family!
- Kim Bley,
mother of 6-year-old Carter who underwent surgery to correct multiple congenital diseases, including transposition of the great arteries (TGA), shortly after birth.
We will always remember the Johns Hopkins Cardiac Surgery family as the people who saved our son’s life. They took care of him—and us—through the toughest days of our lives. Benji healed at the care of the Hopkins staff and is home now— thriving, healthy, and growing every day!
- Katy and Rory Murray,
parents of 5-month-old Benji who underwent surgery to treat severe aortic stenosis.
The team at the Heart Center is amazing! In the midst of the COVID-19 pandemic, the heart valve that was placed 29 years ago to correct my tetralogy of Fallot, failed. This team has made it so I can continue caring for the 6 children I was fortunate to bring into this world, and so I can return to living the active lifestyle I have grown to love.
- Lela White,
Underwent pulmonary valve replacement at Johns Hopkins.
Before Navy was born, she was diagnosed with a rare congenital heart abnormality called tetralogy of Fallot with an absent pulmonary valve. Because Navy was so small at birth, pediatric cardiac surgeon Bret Mettler suggested she wait until she got bigger to have surgery. After a few months at home, Navy returned to Johns Hopkins Children's Center to undergo open-heart surgery.
