Clinical profile of undergoing aortic valve replacement for aortic stenosis

Abstract

The prevalence of calcific aortic stenosis increases with age, being present in 2% to 4% of adults over the age of 65 years. Population-based studies such as the Helsinki Aging Study showed a prevalence of aortic sclerosis to be 21% in adults aged 55–71 years and according to Cardiovascular Health Study (CHS) the incidence of aortic sclerosis was 26% in adults over the age 65 years or older. 75 consecutive patients who underwent aortic valve replacement with TTK-Chitra valve for aortic stenosis at the Department Of Cardio-Thoracic and Vascular Surgery, were studied prospectively. Patients were admitted after routine cardiology OPD screening and investigations as per institutional pre-admission protocol which included transthoracic echocardiography, ECG, chest roentgenogram and haematological investigations. There was no significant difference in EF of patients pre and post operatively. Significant change was observed at one year follow up. The mean EF pre-operatively was 61.00±7.26%, followed by 61.04±7.76%, 62.00±5.56% and 62.96±5.14% at immediate post-op, 3 months and 1 year respectively. The functional class of patients showed significant improvement at one year post surgery.
