Abstract


Background

The indications and benefits of aortic valve replacement have been clearly established, even for elderly populations with high prevalence of comorbidities. However, concern arises about the indication of aortic valve replacement in this population due to manipulation of aortic atheromas, use of cardiopulmonary bypass and cross clamping of the aorta, cardiac arrest and decalcification that are related with this procedure, and their eventual consequences.

Objectives

To report morbidity and mortality of the procedure in octogenarians and validate the usefulness of the risk scores most frequently used.

Material and Methods

A total of 87 octogenarian patients undergoing isolated aortic valve replacement were included; preoperative, operative and postoperative variables were analyzed, and EuroSCORE was estimated; the population was divided into three groups 

of risk (low, moderate and high) for logistic EuroSCORE analysis. A conventional surgical technique was used. The medical records were analyzed and/or telephone contact was used for follow-up.
