Webb1 sep. 2015 · Posterior root enlargement is a useful technique for the management of a small aortic root and annulus and may result in lower transvalvular gradients and better functional outcomes. Although root enlargement is rarely necessary, the techniques should remain in the armamentarium of cardiac surgeons. Webb10 apr. 2024 · We compared the incidence of prosthesis-patient mismatch (PPM) and cardiac adverse events among the groups and sub-analyzed the PPM rate in small aortic annulus (18-21 mm).

The method used has important potential clinical implications on TAVI strategy. The annulus size is in general 1 mm smaller by TTE than by TEE, and the TEE measurement is 1 to 1.5 mm smaller than MSCT measurements. cows farm animals
