OBJECTIVE Transcatheter aortic valve implantation (TAVI) has become an alternative to surgical aortic valve replacement (sAVR) in selected high risk patients. While improvement in left ventricular function after TAVI has been demonstrated, little is known about the impact on right ventricular (RV) function. Since postoperative RV dysfunction is linked to(More)
We report on our experience with a simplified elephant trunk (ET) procedure with a multi-branched prosthesis (Vascutek® Siena™ Collared Graft). It consists of a proximal portion (20 cm) with prefabricated side branches, a collar and a distal portion (30 cm). The collar, which can be trimmed into any desired diameter, constitutes the suture portion to the(More)
BACKGROUND Mitral valve surgery for the correction of secondary mitral valve regurgitation (MR) in cardiomyopathy is associated with a poor outcome. Numerous studies have identified a severe left ventricular dysfunction as an indicator for a poor prognosis. The aim of the study was to asses the follow-up after mitral valve surgery and severe left(More)
BACKGROUND Secondary mitral insufficiency (SMI) is an indicator of a poor prognosis in patients with ischemic and dilated cardiomyopathies. Numerous studies corroborated that mitral valve (MV) surgery improves survival and may be an alternative to heart transplantation in this group of patients.The aim of the study was to retrospectively analyze the early(More)
BACKGROUND It is known that the use of a cardiopulmonary bypass (CPB) during cardiac surgery leads to leukocyte activation and may, among other causes, induce organ dysfunction due to increased leukocyte recruitment into different organs. Leukocyte extravasation occurs in a cascade-like fashion, including capturing, rolling, adhesion, and transmigration.(More)
BACKGROUND Predicting improvement of myocardial function after transcatheter aortic valve implantation (TAVI) for aortic stenosis (AS) remains a challenge. As ejection fraction (EF) may be of limited value in detecting early myocardial dysfunction and predicting outcome, we assessed the potential of echocardiographic longitudinal function in this setting.(More)
INTRODUCTION Left ventricular assist devices have been successfully used as a bridge to cardiac transplantation. Because many patients exhibit marked clinical improvement of their heart failure after LVAD implantation, we studied the physiological effect of pulsatile and non-pulsatile devices on the neurohormonal axis and exercise capacity. METHODS We(More)
BACKGROUND The radial artery (RA) is increasingly used for myocardial revascularization because of its presumed advantageous long-term patency rates. The vessel can be harvested as a pedicle or skeletonized. The aim of this study was to compare the skeletonization technique with pedicle preparation using either an ultrasonic scalpel or scissors. METHODS(More)
OBJECTIVES The Trifecta valve (St. Jude Medical) was introduced into clinical practice as a tri-leaflet stented pericardial valve designed for supra-annular placement in the aortic position. The present study aims to evaluate the preliminary results with this new bioprosthesis. METHODS Seventy patients underwent aortic valve replacement (AVR) with the(More)
BACKGROUND Everolimus is a proliferation-signal inhibitor which was introduced for heart transplant recipients in 2004. To date, there are only sparse data about long-term calcineurin inhibitor (CNI)-free immunosuppression using everolimus. METHODS After heart transplantation, patients receiving everolimus were consecutively enrolled. Reasons for(More)
