Novel Pressure-Regulated Deployment Strategy for Improving the Safety and Efficacy of Balloon-Expandable Transcatheter Aortic Valves.
JACC Cardiovasc Interv
November 2021
University of Sydney, School of Medicine and Health, Sydney, Australia; Macquarie University Hospital, Sydney, Australia; Royal Prince Alfred Hospital, Sydney, Australia. Electronic address:
Objectives: The authors propose a novel pressure-regulated method for balloon-expandable transcatheter heart valve (THV) deployment, aimed at optimizing prosthesis-annulus apposition while preventing significant tissue injury.
Background: The optimal method for balloon-expandable THV deployment remains debated. Current protocols are volume dependent, relying on under- and overfilling of the deployment apparatus.
Prosthesis/annulus discongruence assessed by three-dimensional transoesophageal echocardiography: a predictor of significant paravalvular aortic regurgitation after transcatheter aortic valve implantation.

Aims: Paravalvular aortic regurgitation (AR) is common after transcatheter aortic valve implantation (TAVI). This study aimed to assess the prosthesis/aortic annulus discongruence by three-dimensional (3D) transoesophageal (TOE) planimetry of aortic annulus and its impact on the occurrence of significant AR after TAVI.
Methods And Results: We included 33 patients who underwent TAVI with a balloon expandable device for severe aortic stenosis.
A prospective "oversizing" strategy of the Edwards SAPIEN bioprosthesis: results and impact on aortic regurgitation.
J Thorac Cardiovasc Surg
February 2013
Department of Cardiology, University Medical Center, Utrecht, The Netherlands.
Objective: Moderate to severe aortic regurgitation is occurring in 20% to 30% of cases after transcatheter aortic valve implantation.
Methods: The purpose of the study was to investigate the impact of a prospective policy of "oversizing" the Edwards SAPIEN bioprosthesis (Edwards Lifesciences LLC, Irvine, Calif) relative to the diameter of the aortic annulus on the rate and severity of aortic regurgitation in 28 consecutive patients initially considered eligible for transcatheter aortic valve implantation on the basis of angiography, multislice computed tomography, and transthoracic echocardiography. This policy included the systematic use of transesophageal echocardiography to exclude borderline patients and the modification of the procedure to use the larger device possible.
Determinants of significant paravalvular regurgitation after transcatheter aortic valve: implantation impact of device and annulus discongruence.
JACC Cardiovasc Interv
September 2009
Cardiology Department, Hopital Bichat, Paris, France.
Objectives: The aim of this study was to assess prosthesis/annulus discongruence and its impact on the occurrence of significant aortic regurgitation (AR) immediately after transcatheter aortic valve implantation (TAVI).
Background: Paravalvular AR might occur after TAVI, but its determinants remain unclear.
Methods: Comprehensive echocardiographic examinations were performed in 74 patients who underwent TAVI with a balloon expandable device.
