How serious is triple vessel disease?

Three-vessel disease (3VD) represents the most severe form of coronary atherosclerosis. Patients with 3VD and/or left main stenosis are considered a high-risk group according to therapeutic guidelines. In comparison with less severe forms of CAD, 3VD has been consistently associated with worse long-term prognosis.

What does a triple heart bypass involve?
