Valves are responsible for maintaining one-way flow of blood through the heart. The mitral, tricuspid, aortic, and pulmonic valves are the four valves in the human heart. Aortic valve lies between the left ventricle and the aorta blood vessel. Aortic valve diseases are caused when the aortic valve does not work properly. Surgeries of the aortic valve are used to treat bicuspid valves, various congenital aortic valve disorders, aortic valve stenosis, and aortic valve regurgitation. Fatigue, loss of energy, swelling of ankles, palpitations, shortness of breath and chest pain are signs of aortic valve diseases. This book aims to shed light on some of the unexplored aspects of aortic valve replacement surgery and the recent researches on this medical procedure. It is a vital tool for all researching or studying this surgical procedure, as it gives incredible insights into the emerging trends and methods.
