ABSTRACT
OBJECTIVES: The superiority of supra-annular aortic prostheses over intra-annular equivalents in long-term haemodynamics and clinical outcomes remains controversial. This study compared outcomes among patients receiving supra-annular or intra-annular prostheses during aortic valve replacement.

METHODS: We enrolled 587 consecutive patients (mean age 55.1?짹?11.3?years; 188 women) undergoing aortic valve replacement with either supra-annular (n?=?316) or intra-annular (n?=?271) mechanical prostheses between 2000 and 2016 in our institute. Clinical outcomes and haemodynamic profiles in the 2 groups were compared after propensity score adjustment.

RESULTS: Early death (1.1% vs 0.6%; P?=?0.863) was equivalent for both groups. Patients receiving supra-annular prostheses showed a lower rate of patient-prosthesis mismatch (1.2% vs 25.8%; P?
CONCLUSIONS: The implantation of supra-annular prostheses resulted in superior haemodynamics and left ventricular mass regression, while conferring no apparent clinical benefits. Follow-up studies are required to further evaluate the impact of superior haemodynamics associated with supra-annular prostheses on long-term clinical outcomes.
