Abstract
Artificial heart valves are associated with a number of problems. This study included 20 patients who presented to the Cardiothoracic Surgery Department, Faculty of Medicine, University of Alexandria, with symptoms of artificial heart valve dysfunction. The aim of this study was to evaluate the results of surgical intervention in those patients. The overall mortality was 25%. Advanced NYHA classification and renal impairment were found to be risk factors for hospital mortality, as well as low ejection fraction, severe pulmonary hypertension, tricuspid disease, long cross clamp time, emergency operations and double valve replacement procedures.
