The Montreal Children’s Hospital (MCH) Cardiology department was one of the first of its kind in both Quebec and Canada, setting the foundation for a tradition of innovation and cutting-edge technologies in treating children with a variety of pediatric cardiac diseases and problems.

The first pediatric heart catheterization (inserting a catheter into a vein or artery to perform diagnostic tests of the heart) in Canada was performed at the MCH in 1946 by Dr. Arnold Johnson. In 1966, Dr. James Gibbons performed a balloon atrial septostomy, the first interventional heart catheterization to be successfully performed in the country.

More recently, the MCH Cardiology department established Quebec’s first congenital Magnetic Resonance Imaging(MRI) program, which began seeing patients in 1994. The first percutaneous pulmonary valve implantation was performed at the Montreal Children’s Hospital in 2007.

With cutting-edge treatments and surgical intervention, we are proud to have a huge number of success stories in our long history. The tradition of innovativecardiac care and interventions continues each day at the MCH.  Learn how our department changes lives from a parent’s perspective in this heart-warming account of a child’s cardiac surgery in Tristan's story.

Our team

The Montreal Children’s Hospital Cardiology Division is staffed by a team of pediatric cardiologists offering a wide range of expertise spanning all areas of cardiology. 

Division Head, Dr. Adrian Dancea, specializes in interventional cardiology.

Dr. Luc Jutras is a cardiac MRI and fetal cardiology specialist.

Dr. Charles Rohlicek combines both clinical and research expertise.

Dr. Tíscar Cavallé-Garrido also specializes in fetal cardiology and is the director of the training program in pediatric cardiology at The Montreal Children’s Hospital.     

Dr. Sylvia Abadir is a cardiologist with specific expertise in invasive electrophysiology.

Dr. Claudia Renaud has recently joined our team and has a focus on fetal medicine.

Our cardiologists work in close collaboration with nurses, technologists, administrative assistants, trainees and other health care providers to deliver complex care to our patients.

Programs and services

The MCH Department of Cardiology’s team of specialized physicians evaluates and treats newborns, infants and children with a variety of different ailments affecting the heart and related circulatory system, including children with congenital (at birth) or acquired heart disease and arrhythmias.

The field of pediatric cardiology has evolved tremendously since its early days and treatment options are now available for even the most complex cardiac conditions, using a combination of complex technical innovations and bringing together experts from different disciplines.  Physicians in the MCH Cardiology Department also treat conditions that occur before a child is born, monitoring fetal cardiac problems and intervening when necessary.

The latest diagnostic methods and technological modalities are available at the MCH, including fetal echocardiography, trans-thoracic and trans-esophageal echocardiography, cardiac magnetic resonance imaging (MRI), diagnostic and interventional heart catheterization and electrophysiology.

We maintain a very close collaboration with the Cardiovascular Surgery team at the MCH as well as the Pediatric Intensive Care Unit, the Neonatal Intensive Care Unit, specialists in Cardiac Anesthesia and other health care providers.  Our physicians receive approximately 4, 000 outpatient visits per year and advise on over 600 inpatient consults annually.

The Montreal Children’s Hospital is linked to the provincial Telehealth network.  Cardiac consultation services, including echocardiography via telemedicine, are offered to other health centers that are part of the Telehealth network.         


Conditions and Treatments

The Division of Cardiology provides comprehensive consultative, diagnostic and therapeutic services for patients with illnesses that affect the heart and circulatory system. This includes children with congenital or acquired heart disease including arrhythmias, cardiac rhythm disturbances and heart murmurs. The MCH Cardiology department provides outpatient (ambulatory) clinics for new consultations and follow-up for over 4,000 children with heart disease annually.

The department also provides inpatient and follow up to hospitalized children with heart disease before cardiac intervention (surgery or catheterization). We are involved with many multidisciplinary care teams within the hospital dealing with complex patient cases.

Our team performs diagnostic tests such as electrocardiogram (ECG), cardiac echocardiography (including fetal cardiac echocardiography), magnetic resonance imaging (MRI) and cardiac magnetic resonance imaging.

The MCH’s skilled team of specialists performs invasive and non-invasive electrophysiology, cardiac interventions and heart catheterizations. A heart catheterization may be performed to obtain essential information about your child’s heart, which our cardiac team uses to formulate a clinical plan in conjunction with other diagnostic tests (clinical exam, magnetic resonance imaging (MRI), echocardiogram, electrocardiogram, etc.)

Cardiac catheterization procedures, including therapeutic interventional catheterization techniques, are performed to eliminate or delay the need for more invasive procedures, such as open-heart surgery. These lifesaving treatments include:

  • Dilatation (opening) of blocked heart valves and narrowed or blocked vessels using a balloon
  • Implantation of wire devices called stents, to treat vascular obstructions
  • Embolization (closing) of abnormal blood vessels and connections in the heart
  • Occlusion (closing) of holes (septal defects) in the heart
  • Obtaining biopsies (sampling of heart muscle)
  • Elimination (by ablation) of aberrant electric circuits that cause cardiac rhythm disturbances

Where the care happens

The Cardiology Centre is situated on the ground floor of the new Montreal Children’s Hospital on the Glen Site (BRC. 3219).  All outpatient visits, as well as non-invasive investigations are carried out in this setting.  The Cardiology Centre is a modern state of the art diagnostic facility that has its own dedicated waiting area.  The heart catheterization laboratory is situated on the OR platform on the 3rd floor.  We perform consultations and follow-up of inpatients throughout the hospital. 

The Cardiology service offers ambulatory patient clinics weekly at the MCH, including a newbon baby clinic for prompt assessment of newborn heart murmurs. 

We also have a special entente with the CHUS Sherbrooke whereas all children with heart disease in their catchment area receive complex cardiac care at The Montreal Children’s Hospital.

The Cardiology service offers consultation services every day.  All requests for consultations from treating physicians are screened and prioritized.  Although most consultations will be carried at The Montreal Children’s Hospital, some screening consults might be redirected to the McGill Cardiology Centre at the Queen Elizabeth Health facility.

The new Glen Site benefits from some key adjacencies hat enhance the quality of the care that we deliver to our patients.  These consist of the proximity between the delivery room and the neonatal intensive care unit, the proximity of the adult congenital unit (MAUDE) and the pediatric Cardiology Centre and the adjacency of the heart catherization laboratory and the surgical OR suite.             


Our department will continue to provide services to outreach clinics in northern Quebec as well as the supervision of echocardiography studies in remote areas (Tele-Cardiology).
