Coronary CTA and CT-FFR in trans-catheter aortic valve implantation candidates: a systematic review and meta-analysis.

Objectives: Screening for obstructive coronary artery disease (CAD) with coronary computed tomography angiography (CCTA) could prevent unnecessary invasive coronary angiography (ICA) procedures during work-up for trans-catheter aortic valve implantation (TAVI). CT-derived fractional flow reserve (CT-FFR) improves CCTA accuracy in chest pain patients. However, its reliability in the TAVI population is unknown.

Tricuspid Valve S-Curves and Chamber Views: Implications for Transcatheter Tricuspid and Pulmonary Valve Interventions, Part 2 of the S-Curves and Chamber Views Series.

Despite the challenges associated with periprocedural imaging, transcatheter tricuspid valve interventions have shown important impact on outcomes. A comprehensive understanding of the anatomy of the right heart and surrounding structures is crucial. One way to optimize these interventions is by identifying the optimal fluoroscopic viewing angles along the S-curve of the tricuspid valve.

CT-Derived Patient-Specific Computer Simulation of the Novel Self-Expanding Evolut FX Implantation: A Case Series.

: Paravalvular leak and permanent pacemaker implantation remain relevant issues after transcatheter aortic valve implantation (TAVI). Novel device development as well as adequate preprocedural device selection can contribute to optimal outcomes. : Computed tomography-based patient-specific computer anatomical analysis and simulation were used in addition to standard preprocedural preparation in three of the first Evolut FX cases in our center.
