Principle and indications of the bypass surgery

The achievement of a bypass surgery aims at bringing blood and oxygen to the heart muscle by building a “bridge” through a healthy artery, which will thus pass above the blocked artery and assure a normal blood flow downstream the blocked area.

The bypass surgery is achieved under several conditions:

- Either the lesions of the heart arteries are too numerous, and/or inaccessible to a revascularization by angioplasty (see corresponding chapter),

- Or an obstruction of the origin of the left coronary artery exists (left coronary truncus), then jeopardising an important surface cardiac territory.
