Key result
A normogram for sizing the neo-aortic root in valve-sparing operations reliably predicted the beyond leaflets area compared to observed values (355 vs 364.7 mm2; r=0.95).
Why the study?
Does a normogram accurately predict the correct size of neo-sinuses of Valsalva in patients undergoing valve-sparing aortic operations?
Observational (n=20)

A newly developed normogram reliably predicts the appropriate graft size for neo-sinuses of Valsalva in valve-sparing aortic operations, potentially avoiding undersized or oversized grafts.

Normogram may guide neo-aortic sizing in valve-sparing surgery; hypothesis-generating and requires prospective validation.
Maselli et al. (2005) conducted an observational in Patients undergoing a valve-sparing aortic operation (n=20). Normogram for sizing neo-sinuses of Valsalva vs. Observed values was evaluated on Beyond leaflets area (r=0.95, p=NS). A normogram for sizing the neo-aortic root in valve-sparing operations reliably predicted the beyond leaflets area compared to observed values (355 vs 364.7 mm2; r=0.95).
