Philosophy of Care

One of my closest family members was born with complex congenital heart disease. She gets her cardiology care at Boston Children’s Hospital, so I have been there – not as a doctor, but as a family member watching her go through surgeries and procedures.  I have seen the cardiology nurses and doctors from Boston Children’s help us when we needed it most.  I understand the ups and downs that come with having a loved one go through these trials.  I remember what it is like to be on the other side.  I try to use those lessons to help make me a better doctor.

When I meet a family for the first time, be it in the fetal clinic with a new diagnosis, the outpatient clinic with a new concern, or over the phone as a consult for a second opinion, I think of it as the beginning of a long relationship.  What I enjoy most about Pediatric Cardiology is the long term bonds I can build with patients and their families, measured not in months but in years.  I am there every step of the way, in the best of times and the most difficult of times. I believe it is the strength of that relationship that helps me deliver better care.


Dr. Rathod completed his medical school at Case Western Reserve University and his pediatrics residency at Rainbow Babies and Children’s Hospital in Cleveland, Ohio.  He also served for an additional year as Chief Resident.  He subsequently completed his cardiology fellowship at Boston Children's Hospital, including serving as Chief Fellow.  His cardiology training included a fourth year as Senior Non-Invasive Fellow.  Dr. Rathod is currently a member of the Non-Invasive Division in the Department of Cardiology at Boston Children's Hospital performing cardiac magnetic resonance imaging (CMR) and fetal, transesophageal, and transthoracic echocardiography.  As a staff cardiologist, he maintains a busy clinical practice as well.  His research interests focus primarily on the use of advanced CMR technologies in predicting outcomes of patients with complex congenital heart disease.  Much of his work is with patients with single ventricle heart disease (e.g. hypoplastic left heart syndrome) or with a Fontan circulation.
