At a glance

Emmanuel Lansac is listed in Pitié-Salpêtrière’s cardiac surgery service. His technique-focused research combines root remodelling with an external ring supporting the valve annulus, aiming to retain the natural aortic valve.

Root and annulus treated together

The studied operation combines root remodelling with external annuloplasty for root aneurysm, with or without aortic leakage.

375-repair comparison

The observational cohort compared 289 dedicated expansible rings with 86 Dacron rings and found fewer late reoperations and recurrent leaks with the dedicated ring.

External annuloplasty: a comparative cohort

Lansac coauthored a study of 375 root-remodelling repairs: 289 used a dedicated expansible external ring and 86 a Dacron ring. The dedicated-ring group had fewer late reoperations and recurrent regurgitation in matched and unmatched analyses.

How to interpret this: Observational cases from 2003–2020, with median follow-up about four years despite ten-year estimates. It is not a randomized comparison with reimplantation or replacement, nor a present-day Pitié-only outcome report. Lansac disclosed a financial relationship with CORONEO.
