Aims: Transcatheter aortic valve implantation (TAVI) is frequently associated with cardiac conduction defects (CCD) requiring permanent pacemaker implantation (PPI). Although new-onset left bundle branch block (LBBB) is often seen, the rate of progression to severe CCD is unclear. We aimed to find clinical and electrocardiographic (ECG) parameters associated with severe CCD requiring PPI in patients with a new-onset LBBB after TAVI and assess its effect on clinical outcome. Methods and results: All consecutive patients undergoing TAVI who developed a new-onset LBBB were retrospectively analysed...

BACKGROUND: The use of transcatheter aortic valve implantation (TAVI) following the introduction of Nitinol autoexpandable devices has spread rapidly during recent years. In addition, cardiac surgery has been revolutionized due to the use of Nitinol-based sutureless prostheses for aortic valve replacement (AVR). During the same period, however, permanent pacemaker (PPM) implantation has emerged as a frequent complication. The study aim was to identify the risk factors of PPM following the implantation of a Nitinol self-expanding prosthesis (for AVR or TAVI)...

With increasing life expectancy, the epidemic of valvular heart disease, especially aortic stenosis (AS), is becoming more prevalent. Transcatheter aortic valve implantation (TAVI) has emerged as an alternative therapy for patients with significant aortic valve disease. It offers a less invasive procedure in comparison to surgical aortic valve replacement (sAVR) and an attractive substitute from the patient's perspective. The evidence for TAVI in inoperable and high risk surgical patients is now established and in the intermediate risk group has been accumulating rapidly and is looking favourable for TAVI...

The analysis is based on a finite element procedure to extract the contact forces between an implanted Nitinol stent and the surrounding host tissue using postoperative CT images. The methodology was applied for patients (N=46) which have undergone a TAVI procedure with the Medtronic CoreValve Revalving System (MCRS) to obtain corresponding deformation and force maps. The postoperative CT data were recorded for each patient in both systolic and diastolic phase of the heart cycle. Scalar parameters were defined, which map deformed geometry and contact force field to mechanically relevant quantities: radial dilatation, radial shape distortion, non-convex points, mean force, a force deviation measure and a pressure equivalent...
