Heart & Lung Animations And Interactives

Coronary bypass surgery involves replacing a diseased or constricted artery with a vein removed, most commonly, from the leg, where blood supply is plentiful.

The surgeons dissect the saphenous vein from the right groin area to the knee. The chest cavity is opened and the heart is elevated. Once the catheders are in place, the doctors begin suturing the new vessel to the heart, effectively repairing the affected blood flow.

When the suturing is complete, the heart is given a slight electrical shock and resumes normal activity.
