ABSTRACT
The number of elderly patients operated on for calcification of their aortic valve has increased over the last decade and reflects the satisfactory outlook for most operative survivors. However, in elderly patients, a small aortic root is not an unusual feature, and those with a body surface area (BSA)>1.70m2 are at risk of replacement device mismatch, leading to suboptimal haemodynamic performance with higher residual postoperative rest and exercise gradients.1
