OBJECTIVES The aim of this study was to identify risk factors for new-onset atrioventricular (AV) block requiring pacemaker (PM) implantation after transcatheter aortic valve implantation (TAVI). BACKGROUND High-grade AV block and consecutive PM implantation are frequent complications following TAVI. METHODS For logistic regression analysis, we included(More)
OBJECTIVE Transcatheter aortic valve implantation has been performed by several groups, most of them either specializing on the transapical (surgeons) or the percutaneous femoral transarterial approach (cardiologists). We achieved both transapical and percutaneous transcatheter valve implantation by a surgical team in a hybrid suite. METHODS Since June(More)
OBJECTIVE To examine the results of root replacement with aortic valve-sparing in patients with bicuspid aortic valve (BAV) or severe aortic regurgitation (AR). METHODS Between 2000 and 2009, 102 patients (mean age 47±17.5 years) underwent aortic valve-sparing procedures for ascending aortic aneurysm or dissection. Patients were assigned to three(More)
In this tutorial we present recently developed nonlinear methods of cardiovascular physics and show their potentials to clinically relevant problems in cardiology. The first part describes methods of cardiovascular physics, especially data analysis and modeling of noninvasively measured biosignals, with the aim to improve clinical diagnostics and to improve(More)
OBJECTIVE Sternal dehiscence after median sternotomy can be a challenging problem in case of multiple fractures or infection. The use of titanium plates is a promising approach for sternal reconstruction. METHODS Titanium plate fixation was used in 15 patients (67+/-5.9 years, 171+/-8.2 cm, 93.6+/-14.9 kg, body mass index 32+/-5 kg/m(2)) with unstable(More)
Pre-eclampsia (PE) is a serious disorder with high morbidity and mortality occurring during pregnancy; 3%-5% of all pregnant women are affected. Early prediction is still insufficient in clinical practice. Although most pre-eclamptic patients show pathological uterine perfusion in the second trimester, this parameter has a positive predictive accuracy of(More)
OBJECTIVES We compared the annulus diameters measured by transthoracic echocardiography (TTE), transesophageal echocardiography (TEE), and dual-source computed tomography (DSCT) before transcatheter aortic valve implantation (TAVI). BACKGROUND In TAVI correct evaluation of the aortic annulus is mandatory to choose the correct prosthesis type and size and(More)
BACKGROUND Transcatheter aortic valve implantation is a highly specialized technique offering a new therapeutic option to patients at high risk for conventional surgery. Complications associated with this catheter procedure differ from complications after surgical aortic valve replacement. This is to report incidence, management, and impact on morbidity and(More)
OBJECTIVE Impairment of the baroreceptor reflex activity reflects an alteration of the autonomous regulation of the cardiovascular system and has proven to predict fatal outcome in patients after acute myocardial infarction. The following study was performed to analyse the baroreceptor sensitivity, heart rate variability and blood pressure variability in(More)
OBJECTIVE Aortic valve replacement in patients with a small aortic annulus is often associated with increased pressure gradients. For this reason, prostheses for completely supra-annular placement have been developed. To evaluate the potential benefit of this design, the present study compared the effectiveness of 1 intra-supra-annular bioprosthesis and 3(More)
