AIMS: Introduction of a novel contrast injection protocol during rotational C-arm CT (RCT) in cardiac catheterisation of patients with aortic stenosis for aortic root assessment. METHODS AND RESULTS: Fifty-two patients underwent RCT imaging with contrast injection performed either into the aorta (Ao-RCT, …

Background : Although the feasibility of three-dimensional (3D) speckle tracking echocardiography (STE) for the evaluation of myocardial function has been demonstrated, the poor reproducibility of strain measurements obtained with 3D STE as compared to two-dimensional (2D) STE has been controversially discussed. Aim …

Transcatheter aortic valve implantation (TAVI) offers a minimal invasive option for the treatment of patients with severe aortic stenosis at high risk for conventional surgery. The objective of this study was to investigate whether there is a positive effect on the left …

Background Imaging of the aortic annulus is paramount for the success of transcatheter aortic valve implantation (TAVI) to obviate prosthesis size mismatch. The aortic annulus is a dynamic structure with alterations of its ellipsoid shape during the cardiac cycle. The objective of …

Background. A myocardial strain reduction by speckle tracking imaging (STI) can potentially be a direct indicator of non-viable myocardium and sudden cardiac death (SCD) risk and could help in identifying high-risk patients currently missed by left ventricular ejection fraction (LVEF) criteria. We …

In contrast to surgical aortic valve replacement pre procedural assessment of aortic, aortic annulus diameter and prosthesis size is essential for successful percutaneous interventional valve therapy. Among different imaging modalities multislice-computed tomography (MSCT) and transesophageal echocardiography (TEE)are routinely used for patient screening. …

Treatment of coronary artery disease can only be effective if myocardial tissue can be identified, that is still viable. To localize scar tissue in relation to the coronary vessels would therefore be desirable for interventional guidance. The aim of this study was …
