ABSTRACT
Introduction Advances in the conventional methods of revascularization, coronary artery bypass surgery and percutaneous angioplasty, have led to the successful treatment of increasing numbers of patients with coronary artery disease. However, there remains a sizeable proportion of patients with severe coronary disease who are unsuitable for these procedures and who remain very symptomatic despite optimal medication. These patients take up large amounts of medical resources and often require repeated hospital admissions and regular outpatient follow-up.
