BACKGROUND During ventricular assist device (VAD) unloading, cardiac recovery is possible even in patients with chronic heart failure (HF). We sought parameters predictive of cardiac stability after VAD removal. METHODS AND RESULTS Among 81 patients weaned since March 1995, a homogenous group of 35 with idiopathic dilated cardiomyopathy weaned from left(More)
The various techniques of preserving the chordal apparatus in mitral valve replacement applied in 1,453 cases at a single institution between 1986 and 1994 are described. The techniques include preservation of chordal attachment to the posterior mitral leaflet only and to both leaflets with five different technical variations. The specific advantages and(More)
BACKGROUND Iatrogenic damage of different structures of the aortic root, in the region of the so-called "device landing zone," may occur during transcatheter aortic valve implantation (TAVI). It is mostly considered difficult to treat or even untreatable. METHODS AND RESULTS We performed a retrospective analysis of the occurrence, clinical presentation,(More)
BACKGROUND Detection of cardiac recovery that allows long-term cardiac stability after ventricular assist device (VAD) explantation is a major goal. After normalization of ventricular diameters during unloading, the pre-explant left ventricular ejection fraction (LVEF) allows the detection of patients with the potential to remain stable after VAD(More)
BACKGROUND As waiting periods for heart transplantation have lengthened, the application of long-term mechanical circulatory support (MCS) has become more common in patients presenting with cardiogenic shock. Anticipating increased long-term MCS, a policy to discharge patients home has been instituted. This study compares the results of outpatient on MCS to(More)
BACKGROUND The recently introduced Impella Recover (Impella CardioSystems AG, Aachen, Germany) microaxial flow left and right ventricular assist devices (LVAD/RVAD) were evaluated as they provide circulatory support in the setting of postcardiotomy heart failure refractory to high-dose inotropic and intra-aortic balloon pump (IABP) support. METHODS(More)
OBJECTIVE The "valve-in-valve" concept may be applied in patients with previously implanted biological aortic valve prostheses. There are few reports of individual cases and as yet no clinical proof of safety and feasibility in a larger group of patients. We report the single-center outcome of transapical implantation of aortic valves into degenerated(More)
BACKGROUND Weaning from left ventricular assist devices (LVADs) after myocardial recovery in patients with idiopathic dilated cardiomyopathy is a clinical option. With the broad application of continuous-flow pumps, we observed a decrease in the numbers of possible LVAD explanations due to myocardial recovery in these particular patients. We investigated(More)
UNLABELLED Axial flow pumps have gained increased acceptance since their first clinical use in 1998. The present report summarizes the clinical experience with patients treated for severe cardiogenic shock for the first time with a newly developed axial flow pump with magnetically levitated bearings. MATERIAL AND METHODS The axial flow pump Incor was(More)
BACKGROUND Midterm results after transapical aortic valve implantation are still unknown in a large group of patients. We report our institutional experience in 300 high-risk patients. METHODS Since April 2008, transapical aortic valve implantation was performed in 300 patients (mean age, 80 ± 8 years). The mean logistic EuroSCORE (European System for(More)
