PY - 2021 T2 - Decision Making in Perioperative Medicine: Clinical Pearls AB - Up to 2.9% of adults without known valvular heart disease have moderate to severe valve pathology on screening studies, and some of these patients will be faced with undergoing noncardiac surgery.1 Older patients are more likely to undergo noncardiac surgery and are also more likely to have significant valvular heart disease. In a cohort study of patients over 65 years old undergoing screening echocardiography, newly detected moderate or severe valve disease was uncovered in 6.4%.2 Advanced age and significant coronary artery disease are associated with calcific and degenerative aortic stenosis. Apart from being older, other risk factors for significant valvular heart disease are listed in Table 12-1.
