St. Michael’s Hospital, a premier teaching hospital affiliated with the University of Toronto and the flagship site of Unity Health Toronto, is known affectionately as the “Urban Angel.” Situated in the heart of downtown Toronto (36 Queen Street East), St. Michael’s has built an international reputation for delivering high-acuity critical care, world-class cardiac interventions, pioneering neurosurgery, and rapid trauma resuscitation.
Whether you are navigating a complex cardiac diagnosis, preparing for delicate brain or spine surgery, or seeking information on specialized medical care in Ontario, this guide covers everything you need to know about St. Michael’s Hospital’s top departments, surgical technologies, and patient services.
World-Class Heart & Vascular Care
The cardiovascular program at St. Michael’s Hospital is one of the most active and advanced in Canada, recognized globally for breakthroughs in structural heart interventions, minimally invasive valve surgeries, and complex arrhythmia treatments.
1. Structural Heart & Valve Interventions
- Transcatheter Aortic Valve Implantation (TAVI): St. Michael’s is a high-volume pioneer in catheter-based valve replacements, allowing patients with severe aortic stenosis to receive a new heart valve without open-chest surgery.
- MitraClip & Tricuspid Valve Repair: Leading-edge catheter procedures designed to treat leaky mitral and tricuspid valves for patients deemed high-risk for conventional open-heart surgery.
- Complex Coronary Angioplasty (PCI): Round-the-clock emergency catheterization suites equipped for high-risk, complex percutaneous coronary interventions to restore blood flow during acute myocardial infarctions (heart attacks).
2. Cardiac Surgery & Electrophysiology
- Advanced Bypass & Surgical Reconstruction: High surgical volumes in coronary artery bypass grafting (CABG), aortic root reconstruction, and minimally invasive cardiac surgical approaches.
- Electrophysiology & Arrhythmia Management: Diagnostic mapping and catheter ablation for atrial fibrillation (AFib), ventricular tachycardia, and the implantation of biventricular pacemakers and subcutaneous ICDs.
3. Heart Failure & Ambulatory Cardiac Clinics
- Specialized clinics for hypertrophic cardiomyopathy, adult congenital heart disease, cardiac rehabilitation, and advanced medical therapy for heart failure patients.
Leading-Edge Neurosurgery & Spine Program
St. Michael’s Hospital is a designated regional neurosurgical referral center, managing complex cranial, cerebrovascular, and spinal disorders with state-of-the-art neuro-navigational technologies.
1. Cerebrovascular Neurosurgery & Stroke Care
- Aneurysm & AVM Management: Advanced endovascular coiling, pipeline embolization, and microvascular clipping for brain aneurysms, arteriovenous malformations (AVMs), and dural arteriovenous fistulas.
- Hyper-Acute Stroke Interventions: Seamless coordination between emergency trauma triage and neuro-interventional suites to perform rapid mechanical thrombectomy for acute ischemic stroke.
2. Brain Tumour & Skull Base Surgery
- Minimally Invasive Endoscopic Approaches: Collaborative neurosurgical and ENT teams utilizing endoscopic endonasal surgery to remove pituitary tumors and skull base lesions through the nasal cavity without external incisions.
- Intraoperative Neuro-Navigation & Fluorescence: High-resolution image guidance and tumor-fluorescence agents (5-ALA) that allow surgeons to visualize and resect malignant brain tumors (gliomas) with sub-millimeter precision while preserving healthy brain tissue.
3. Complex Spine Surgery & Trauma
- Surgical correction of spinal deformities, decompression for spinal stenosis, cervical disc replacement, and emergency surgical stabilization of traumatic spinal cord injuries.
Critical Care & Level 1 Adult Trauma Hub
Beyond its cardiovascular and neurosurgical prestige, St. Michael’s Hospital operates one of Ontario’s busiest Level 1 Adult Trauma Centres.
- Downtown Trauma Hub: The specialized Trauma Resuscitation Area handles major multi-system injuries, acute penetrating wounds, severe falls, and blunt force trauma across the Greater Toronto Area.
- Direct Trauma ORs & Heliport Access: Dedicated trauma surgical suites and rooftop helipad facilities ensure instant transfer from air-ambulance to critical life-saving surgical intervention.
- The Peter Gilgan Patient Care Tower: A 17-storey modern critical care facility featuring enlarged, specialized intensive care units (ICUs) designed with infection-control private suites for cardiovascular, trauma, and neurosurgical recovery.
