Early and late outcomes after isolated aortic valve replacement in octogenarians: an Australasian Society of cardiac and thoracic surgeons cardiac surgery database study

Objective: The advent of percutaneous aortic valve implantation has increased interest in the outcomes of conventional aortic valve replacement in elderly patients. The current study critically evaluates the short-term and long-term outcomes of elderly (=80 years) Australian patients undergoing isolated aortic valve replacement. Methods: Data obtained prospectively between June 2001 and December 2009 by the Australasian Society of Cardiac and Thoracic Surgeons National Cardiac Surgery Database Program were retrospectively analysed. Isolated aortic valve replacement was performed in 2791 patients; of these, 531 (19 ) were at least 80 years old (group 1). The patient characteristics, morbidity and short-term mortality of these patients were compared with those of patients who were
