Interventional cardiology refers to diagnostics and non-surgical treatments of the heart. Cardiac interventions are used to diagnosis and treat many types of heart disease. Stanford interventional cardiology is a world leader in percutaneous coronary revascularization, which re-establishes blood flow to the heart when its vessels have been damaged or blocked. Each year, the staff of the Section of Invasive and Interventional Cardiology sees thousands of patients with almost every kind of heart disease. Our interventionists treat people of all ages from around the world who have serious, sometimes life-threatening, cardiac conditions.
