Patients with severely calcified aorta have high risk of atheroemboli and bleeding during cardiac surgery. Clamping the ascending aorta to initiate cardiac arrest or to perform proximal anastomosis is a challenging problem. Beating heart coronary artery bypass grafting without aortic clamping is usually accepted as the best solution. Herein, we present a feasible and inexpensive proximal anastomosis technique without using aortic clamps for patients with severely atherosclerotic aorta.
