Academic Interests: Device development/testing, Teaching INR Fellows

Dr. Marotta has a long history with St. Michael’s Hospital. He was born here. He also trained here. St. Michael’s Hospital is also where his mother and father met — she was a nurse and he became chief of Medicine. Today, Dr. Tom Marotta runs a weekly neurovascular clinic in the Marotta Clinic, named in honour of his father’s contributions in neurology and medicine.

Dr. Marotta is a minimally invasive neurointerventionalist. He treats patients with neurovascular conditions such as acute strokes and ruptured brain aneurysms. “We see patients with complex neurovascular conditions that require input from many areas including neurosurgery, neurology, neuroradiology and interventional neuroradiology.”

It is this collaborative team that makes St. Michael’s Hospital a great place to work. “Each of us has a different area of interest and expertise that we combine for the benefit of our patients,” he says.

Dr. Marotta trained as an intern, a neurosurgical resident and radiology resident at St. Michael’s Hospital before pursuing further training and practice in Canada and the United States. After establishing a neurointerventional service at Vancouver General Hospital, he returned to St. Michael’s in 2001 to support a similar program here with Dr. Walter Montanera. Today this program sees patients from across Toronto, throughout Ontario and beyond.

Dr. Marotta also participates in clinical studies to better understand neurovascular conditions and to develop new ways to treat them. Specifically, he has a particular focus on developing new devices to treat patients with brain aneurysms in a less invasive way. For example, he has his own patented invention to treat brain aneurysms that has been used to treat patients here in Canada and abroad.

“St. Michael’s Hospital is a supportive environment to work in, to train others, and to conduct innovative research,” he says. “Everything we do is with our patients in mind and it is an honour to work with such an outstanding team.”
