Plunde et al 20217	32 SAVR, 67% male, mean age 69	⇔	⇔/↑	3	cfPWV (SphygmoCor) CAVI, baPWV	↑ CAVI/baPWV, ⇔ cfPWV

Notes: A summary of studies assessing aortic/arterial stiffness before and after aortic valve replacement (AVR). Importantly, this tables incorporate a variety of methods including indirect measures of stiffness such as augmentation index, which is also dependent on other entities. Mobil-O-Graph (MOG) is a highly questioned method to determine arterial stiffness as it is almost entirely dependent on age and systolic blood pressure.

Abbreviations: TAVI, transcatheter aortic valve implantation; SAVR, surgical aortic valve replacement; cfPWV, carotid-femoral pulse wave velocity; AIx, augmentation index; MRI, magnetic resonance imaging; ASi, aortic stiffness index; LV, left ventricle; aPWV, aortic pulse wave velocity.
