Coronary arteries

Coronary artery disease is the most common form of heart disease. It happens when the arteries in the heart become narrowed, stiff, or blocked, which prevents blood from flowing. If left untreated, coronary artery disease can lead to chest pain, heart attacks, and cardiac arrest (when the heart suddenly stops). In more rare cases, the artery can suddenly tear, known as Spontaneous Coronary Artery Dissection or SCAD. Sunnybrook’s Schulich Heart Program uses the latest techniques and knowledge to give people with even the most severe coronary artery disease a second chance at life.

Angioplasty & Stenting
