Conclusions
SEV ( self-expandable valves ) were associated with a lower frequency of PPM compared with BEV ( balloon-expandable valves ) irrespective of annulus area. The difference was mainly driven by larger patients with BSA >1.83 m2.

Por que as auto expandidas geram menos gradiente e mismatch?
Comparada à expandida por balão:
Hipótese:
Como a maioria dos pacientes são idosos com septo sigmóide, uma prótese que age mais profundamente na via de saída pode ajudar no gradiente pré valvar.
