The Boston Children’s Hospital Complex Biventricular Repair Program is a multidisciplinary effort to provide an option for “two ventricle” circulation in newborns and children who are being considered for, or have undergone, single ventricle repair. We treat each patient with a tailored, personalized approach, based upon the unique characteristics of every child’s heart.

Our highly specialized interdisciplinary team of pediatric cardiologists, cardiac surgeons, cardiac anesthesiologists, cardiac ICU team and nurse practitioners treat children who would not be candidates for biventricular repair in most other hospitals. In 2012 alone, we saw about 80 children with heterotaxy syndrome and 120 with HLHS. In 2014, we performed 1,500-plus cardiac catheterizations, 886 open-heart surgeries and 535 closed-heart surgeries. We take a very specialized approach in order to find the best method to evaluate, diagnose and treat your child or patient. We use novel procedures and innovative technology, including advanced imaging and simulation modeling.

Conditions and Treatments

Our specialists treat the full spectrum of heart disorders and diseases, including:

Atrioventricular Canal Defect
Double Outlet Right Ventricle (DORV)
Hypoplastic Left Heart Syndrome (HLHS)
Pulmonary Atresia
Single Ventricle Defects
Transposition of the Great Arteries (TGA)
Twin Reversed Arterial Perfusion (TRAP)

Research and Innovation

In 1938, Boston Children’s cardiac surgeon Robert Gross, MD, performed the world’s first successful surgery to correct a child’s heart defect. Since that time, our program’s culture has been one of innovation — of solving difficult problems that others haven’t been able to solve, tackling the most complex cases, and figuring out ways to make the process easier on patients. We are focused on developing new methods to repair rather than replace whenever possible, with minimally invasive approaches.

The depth of our team and our clinical innovations make us leaders in biventricular repair. Our imaging center is unique in the application of 3-D printing technology to create models of each patient’s heart based on imaging tests. This can be used to aid surgical planning and explain procedures to family members.

Next Steps

For questions, more information, or to schedule an appointment for your child, please call the International Heart Center anytime at +1-857-218-3913 or email You may want to begin gathering relevant paperwork such as the patient’s height and weight, medications, most recent echocardiogram in DICOM-preferred format (and accompanying report), most recent cardiology summary and clinical status, as well as any other recent cardiac studies such as cath, MRI or CT scans.
