Intraoperative 2D and 3D Transoesophageal Echocardiographic Predictors of Aortic Regurgitation After Transcatheter Aortic Valve Implantation

Study Questions:

Among patients undergoing transcatheter aortic valve implantation (TAVI), are there features of the native aortic valve on intraoperative two-dimensional (2D) and three-dimensional (3D) transesophageal echocardiography (TEE) that are associated with significant postprocedural paravalvular aortic regurgitation (AR)?
