Do less flow-dependent measures like resistance improve the accuracy of aortic stenosis severity assessment compared to standard AVA techniques in elderly patients?
Standard AVA assessment techniques frequently misclassify critical aortic stenosis in the elderly, suggesting less flow-dependent measures like resistance should be considered to guide valve replacement.
Standard techniques of AVA assessment for AS show poor correlation in elderly patients, with frequent misclassification of critical AS. Less flow-dependent measures, such as resistance, should be considered to ensure that only appropriate patients are treated with aortic valve replacement.
