Catheter-based aortic valve implantation is increasingly being performed in high-risk patients with symptomatic aortic valve stenosis. For successful planning of the procedure, CT has been shown to provide crucial information concerning the aortic root as well as the peripheral access vessels. This article illustrates the increasing role of CT before transcatheter aortic valve implantation. 

Critical Aortic Stenosis in a Patient with a Abdominal Aort Dissection and Narrowed: Simultaneous Transcatheter Aortic Valve Implantation and Endovascular Aortic Repair

The cardiovascular assessment of other comorbidities in patients with severe aortic stenosis and a high perioperative risk or a contraindication for open surgery is critical for ensuring better clinical outcomes.

Role of computed tomography in transcatheter aortic valve implantation and valve-in-valve implantation: complete review of preprocedural and postprocedural imaging.

Retrospective ECG-gated cardiac computed tomography (CT) today is the gold-standard imaging technique that provides three-dimensional images of the heart, thus allowing a rapid and complete evaluation of the morphology of the valve, ascending aorta, coronary arteries, peripheral access vessels, and prognostic factors.

Transcatheter aortic valve implantation operators - get involved in imaging!

All TAVI operators should know how to assess the annulus, the annular root, and the iliofemoral access, to improve outcomes of this evolving procedure.

Transcatheter aortic valve replacement with a focus on transcarotid: a review of the current literature.

This manuscript will provide a review of the current literature on transaortic, transapical, transaxillary and transcarotid approaches to transcatheter aortic valve replacement (TAVR) while focusing on the trans carotid approach.

Role of Imaging in Transcatheter Aortic Valve Replacement

The current state of imaging in the pre-interventional setting of TAVR with a special emphasis on CT is reviewed, including high-pitch, low kV acquisitions, and iterative reconstruction resulting in high image quality at substantially reduced scan duration, contrast volume, and radiation exposure.

The role of computed tomography in the planning of transcatheter aortic valve implantation: a retrospective analysis in 200 procedures

CT evaluation assures a safe, reliable and prognostically relevant method for TAVI preprocedural planning and is essential in order to minimize possible complications and to improve the quality of the therapeutic planning.

The Iliofemoral tortuosity score predicts access and bleeding complications during transfemoral transcatheter aortic valve replacement: Data from the VIenna Cardio Thoracic aOrtic valve registrY (VICTORY)

The impact of novel scoring methods of iliofemoral tortuosity on access and bleeding complications after transfemoral transcatheter aortic valve replacement is investigated.

Three-Dimensional Transesophageal Echocardiography as an Alternative to Multidetector Computed Tomography in Aortic Annular Diameter Measurements for Transcatheter Aortic Valve Implantation

3D TEE can be the solution for aortic annular measurements used to select the correct prosthesis for the transcatheter aorti valve implantation procedure in patients who cannot undergo computer tomography, and is used as an alternative in cases where MDCT is contraindicated or not available.

Role of CT Imaging for Coronary and Non-coronary Interventions

The role of cardiac CT for the guidance of different cardiac interventions will be described in this review, with widespread acknowledgment that CT is particularly useful for pre-interventional imaging with increasing implementation in clinical routine.

Modern cardiac surgery: the future of cardiac surgery in Australia

The face of modern cardiac surgery is explored and how this may be taken up in Australia and implications for the provision of training are explored.

Anatomical and Procedural Features Associated With Aortic Root Rupture During Balloon-Expandable Transcatheter Aortic Valve Replacement

It is demonstrated that LVOT calcification and aggressive annular area oversizing are associated with an increased risk of aortic root rupture during TAVR with balloon-expandable prostheses.

Prosthesis Oversizing in Balloon-Expandable Transcatheter Aortic Valve Implantation Is Associated With Contained Rupture of the Aortic Root

To retrospectively investigate the potential cause of contained rupture of the aortic root in balloon-expandable transcatheter aortsic valve implantation (TAVI) by means of pre- and postinterventional multislice computed tomography, 72 patients underwent TAVI and 3 patients were diagnosed with contained rupture.
