ABSTRACT

Aortic valve disorders have experienced a dramatic change during the last four decades since the first prosthesis were implanted. The main cause of valve disorders has gone from rheumatic to degenerative and, as a result, other disorders have emerged throughout the years. In the Western world it has become the third most common cardiovascular disease.
Objective: Determine the progress made by patients over 60 suffering from left ventricular dysfunction after aortic valve surgery at the ICCCV.
Method: Clinical records were checked and an observational descriptive and cross-sectional study was carried out.
Results: 247 patients were studied and the average age was 65. Out of the 247 patients, 58, 3 % were male and 41, 7 % were female. The most common disorder among the patients was aortic stenosis (46.6%) and a degenerative cause was most frequent in both sexes. Class III and class IV ventricular dysfunction presented similar behavior in terms of deceased and alive. Women have the same death rate as men despite the fact that they are less in number (2.9%). Most frequent postoperative complications were renal dysfunction (17.2%) and postoperative HBP (19.1%) both in males and females.
Conclusions: Aortic stenosis continues to be a predominantly male disorder and its degenerative cause is increasingly replacing rheumatic causes. Left ventricular dysfunction associated to aortic stenosis has a natural unfavorable prognosis.
