My area of clinical expertise is pediatric and fetal interventional catheterization, with particular focus on device-based therapies. My professional activity is divided between clinical care (70%), research (20%) and teaching (10%).

As one of 6 invasive cardiologists staffing the largest pediatric catheterization program in the country, I perform over 250 procedures a year, most of which are interventional. I frequently provide interventional consultation to colleagues within my own Department, and to cardiologists throughout New England, and am also consulted by peers in interventional cardiology from around the country. My practice encompasses all types of catheter-based intervention for congenital heart disease, and includes several specific interventions that were either described by our group, or are almost exclusively performed here.

I also devote clinical time to the fetal cardiac interventional program, the only program of its kind in the world. Since its inception in 2000, the providers in this program have performed over 120 fetal catheterizations, an experience that is ten-fold any other in North America. In addition to responding to patient referrals and providing consultation to referring cardiologists and families, my role includes assessing candidacy for intervention, educating the families about these highly innovative procedures, and executing the interventional component of the procedures.

My research focuses on fetal cardiac catheterization, with emphasis on the development of new procedures and devices. I have been a coinvestigator on the first 2 prospective trials of fetal cardiac catheterization, and recently assumed the role of PI for one of them. Our team has published techniques and outcomes for in utero aortic and pulmonary valvuloplasty, and atrial septoplasty. I have designed 2 instruments for fetal intervention, securing a patent for one of these. In other work, I serve as the site principal investigator or coinvestigator for 3 prospective multicenter trials of investigational devices used to treat pediatric patients with congenital heart disease.

Training pediatric cardiology fellows to understand cardiac anatomy and physiology in the catheterization laboratory constitutes my primary teaching contribution, and teaching is a critical component of all of my procedural activity. In preparation for cath cases, I lead the rotating fellows in a discussion of each patient and procedure, covering acquisition and interpretation of hemodynamic data, and plans for intervention. In addition, each year my division trains a senior interventional cardiology fellow, selected from an international applicant pool. I have daily interaction with these senior trainees. Several have published successfully with my guidance and all have gained positions as interventional cardiologists at academic centers.

My clinical work also involves significant inpatient service commitments. Many patients are referred by a group of 4 pediatric cardiologists in Providence, RI, to whom I also frequently provide second opinions regarding broader management of complex cases. When these patients require inpatient care, catheterization or surgery, I serve as their attending physician, typically rounding on 4-6 patients daily. I have expanded my collaboration with this cardiology group by initiating a program in pediatric catheterization based at Rhode Island Hospital, where I perform procedures 1-2 times each month.

Practice Activities

Area of practice: Pediatric Cardiology

1. Interventional Cardiology

Performing diagnostic and interventional cardiac catheterization in the Children's Hospital Cardiac Catheterization Laboratory, 5 cases/wk (~250 cases/year).

Performing cardiac catheterization at Rhode Island Hospital as part of collaborative program, 1-2 cases/month

2. Fetal Interventional Cardiology

Performing fetal cardiac interventions, 1-2 cases/month, with a collaborative multidisciplinary team from the Brigham and Women's Hospital and Children's Hospital

Consulting nationally with referring cardiologists and families regarding cardiac intervention through the Advanced Fetal Care Center at Children's Hospital Boston, 2-3 cases/month

3. Inpatient Cardiology Services

Examining and completing rounds on inpatients, including postoperative patients in the intensive care unit, cardiology inpatient unit, or extended recovery unit at Children's Hospital Boston, typically 4-6 inpatients/day

4. Outpatient Cardiology Clinic

Managing both new patients with general cardiology chief complaints, as well as known patients with more complex structural heart disease in the ambulatory clinic at Children's Hospital Boston, 2 sessions/month

Clinical Innovations

Prevention of hypoplastic left heart syndrome by means of in utero aortic valvuloplasty in the second trimester of pregnancy.

Collaborated with a pioneering team to successfully perform the first procedures and report the results. As a result, there is greater emphasis on prenatal diagnosis of HLHS and the potential for prenatal intervention has been recognized throughout the field. Centers in the US and overseas have attempted the procedure, with our input and training, and have succeeded in several sites.

Prenatal intervention to avert neonatal shock presentation in babies with hypoplastic left heart syndrome with intact atrial septum variant.

Designed and performed the first ever creation of an atrial septal defect in utero, and placed the world's first fetal intracardiac stent. Demonstrated that this intervention can improve postnatal presentation in a highly lethal disease. We now receive referrals from all over the country to assist in the management of these fetuses.

Hybrid approaches to congenital heart disease

Worked with cardiac surgical colleagues to adopt hybrid surgical and catheter approaches and integrate these innovative approaches into practice at Children's Hospital. Examples include hybrid Stage I operation for hypoplastic left heart syndrome, intraoperative angiography, intraoperative valvuloplasty and angioplasty.
