Hemodynamic markers of pulmonary vasculopathy for prediction of early right heart failure and mortality after heart transplantation.

Background: Elevated pulmonary vascular resistance (PVR) is broadly accepted as an imminent risk factor for mortality after heart transplantation (HTx). However, no current HTx recipient risk score includes PVR or other hemodynamic parameters. This study examined the utility of various hemodynamic parameters for risk stratification in a contemporary HTx population.

Microembolic signal monitoring in patients with HeartMate 3 and HeartWare left ventricular assist devices: Association with antithrombotic treatment and cerebrovascular events.

Background: In patients with left ventricular assist devices (LVADs), ischemic and hemorrhagic stroke are dreaded complications. Predictive markers for these events are lacking. This study aimed to investigate the prevalence and predictive value of microembolic signals (MES) for stroke, detected by Transcranial Doppler sonography (TCD) in patients with HeartMate 3 (HM 3) or HeartWare (HW).

Gastrointestinal Endoscopy Is Safe in Patients Before and After Lung or Heart Transplantation.

Background: Gastrointestinal complications are common in patients after lung and heart transplantation. Endoscopy is a standard method for the assessment of gastrointestinal morbidities. The aim of this study was to analyze the number and type of complications during endoscopic procedures in patients before and after lung or heart transplantation.

Ribavirin treatment of acute and chronic hepatitis E: a single-centre experience.

Background: The role of ribavirin for treatment of severe acute or chronic hepatitis E virus (HEV) infection is not well defined.

Aims: To investigate the applicability and efficacy of ribavirin therapy in acute and chronic HEV infections within a large single-centre cohort.

Materials & Methods: Clinical courses of forty-four German HEV-infected individuals were analysed.

Steroid withdrawal and reduction of cyclosporine A under mycophenolate mofetil after heart transplantation.

Survival and quality of life after heart transplantation are limited by a significant incidence of cardiovascular complications. Side effects of immunosuppressives contribute unfavorably. Aim of this study was to determine (1) whether withdrawal of corticosteroids and dose reduction of cyclosporine A can be performed safely under immunosuppressive therapy with mycophenolate mofetil and (2) if this is beneficial for renal function and cardiovascular risk reduction.

Angiographic assessment of cardiac allograft vasculopathy: results of a Consensus Conference of the Task Force for Thoracic Organ Transplantation of the German Cardiac Society.

Angiograms of cardiac transplant (HTx) recipients were to be evaluated in a ring experiment and a joint consensus on criteria of angiographic evaluation of coronary arteries of HTx patients was to be reached. Twenty-four coronary angiograms from 11 hospitals were circulated. One hundred eighty-eight blinded evaluations were returned.

Simulation of the fluid dynamics in artificial aortic roots: comparison of two different types of prostheses.

As a consequence of the growing number of elderly people, the incidence of degenerative aortic diseases continues to increase. Often, artificial aortic roots are needed to replace the native tissue. Some physical characteristics of the artificial aortic root, however, are quite different from native aorta and need to be optimized.
