..We report on 2-year follow-up clinical and echocardiographic results after transcatheter aortic valve implantation in 227 patients...

..It is presumed that patient-prosthesis mismatch (PPM) influences morbidity and mortality after aortic valve replacement (AVR). The aim of our study was to determine the impact of PPM on physical capacity...

..To predict the occurrence of valve prosthesis-patient mismatch (VP-PM) after aortic valve replacement (AVR), the surgeon needs to estimate the postoperative effective orifice area index (EOAI)...

..The aim of this study was to investigate neurologic sequelae of the donor arm compared with those occurring after the conventional harvesting technique...

..On the basis of its specialized design, with the pericardium mounted on the outside of the stent, the Mitroflow valve is considered to provide optimal opening and orifice areas...

..In such cases, catheter-based techniques for aortic valve implantation are a new therapeutic option. In this paper, we describe the initial results obtained at the German Heart Center, Munich, with a new technique of this kind...

..Transsection of the artery is carried out with a pre-tied endoloop. The endoscopic harvesting can be done in 45 minutes, resulting in less operative trauma and an excellent cosmetic outcome...

..The present paper aims to demonstrate that optimal therapy should be provided by a multidisciplinary team consisting of cardiac surgeons, cardiologists and cardioanesthesiologists in a hybrid suite...

..To improve patients' acceptance of the radial artery as a graft for coronary revascularization, we introduced an endoscopic harvesting technique. The aim of this study was to assess graft quality 1 year after the operation...

..It is assumed that a right anterolateral thoracotomy for correction of simple congenital cardiac defects (ie, atrial septal defect) achieves more favorable cosmetic results than a standard median sternotomy...

..We report on the short- and long-term implications of the apical-access-site-specific complications...

..These reference values may not reflect the actual in vivo EOAI and hence, the presence or absence of PPM may be based on false assumptions...

..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)...

..We analyzed survival in patients undergoing transcatheter aortic valve implantation with special emphasis on the access site for implantation...

..This study compares the hemodynamic performance and the incidence of patient-prosthesis mismatch (PPM) of both prostheses...

..This is accompanied by a significant left ventricular mass regression, an important indicator for long-term survival...

..quot; An in vitro investigation was initiated to identify the underlying mechanism...

..We achieved both transapical and percutaneous transcatheter valve implantation by a surgical team in a hybrid suite...

..The present study evaluates complete supra-annular bioprostheses in patients with an aortic annulus of 18 to 23 mm in diameter...

..We evaluated 5 bioprostheses designed for complete supraannular placement to assess potential hemodynamic differences caused by factors (eg, valve material) other than implantation position...

..The midaxillary approach may help to avoid these side effects and improve the cosmetic result...

..To examine the results of root replacement with aortic valve-sparing in patients with bicuspid aortic valve (BAV) or severe aortic regurgitation (AR)...

..This prospective randomized study compares a porcine with a bovine bioprosthesis in the aortic position with regard to hemodynamic performance during exercise...

..We have now successfully employed the technique to close atrial septal defects in the oval fossa in 17 pre-pubescent females...

..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)...

..Especially in this subset of patients, the expected improvement of quality of life (QoL) after valve implantation will be critical for decision-making for TAVI...

..The study aim was to assess long-term morbidity and mortality with special regard to prosthesis durability after aortic root replacement with the Hancock bioprosthetic porcine conduit...

..The study aim was to evaluate the clinical and hemodynamic performance of the Sorin Soprano bioprosthesis in the aortic position...

....

..The study aim was to compare the hemodynamic performance of the ES valve with the completely supra-annular Medtronic Mosaic (MM) porcine valve...

..The purpose of this study was to evaluate the long-term performance of the St. Jude Medical Biocor stented porcine prosthesis in the aortic position...

....

..The aim of this prospective randomized trial was to evaluate the impact of complete supraannular positioning of mechanical aortic bileaflet valves...

..The ascending aorta approach might help to expand the implantation possibilities for those patients for whom the typical access sites are not available...

..During routine follow-up performed at discharge and annually after the operation, intermittent moderate transvalvular regurgitation was detected by echocardiography in 5 patients...

..As expected, ANP mRNA expression was high in LVH patients. We propose a prominent role for CnB in controlling Cn activity in compensated LVH. At this stage of the disease, MMP and TIMP activities are balanced...
