Indications, Complications, and Outcomes of Cardiac Surgery After Heart Transplantation: Results From the Cash Study.

Background: Allograft pathologies, such as valvular, coronary artery, or aortic disease, may occur early and late after cardiac transplantation. Cardiac surgery after heart transplantation (CASH) may be an option to improve quality of life and allograft function and prolong survival. Experience with CASH, however, has been limited to single-center reports.

The European Registry for Patients with Mechanical Circulatory Support (EUROMACS): second EUROMACS Paediatric (Paedi-EUROMACS) report.

Objectives: A second paediatric report has been generated from the European Registry for Patients with Mechanical Circulatory Support (EUROMACS). The purpose of EUROMACS, which is operated by the European Association for Cardio-Thoracic Surgery, is to gather data related to durable mechanical circulatory support for scientific purposes and to publish reports with respect to the course of mechanical circulatory support therapy. Since the first report issued, efforts to increase compliance and participation have been extended.

Results of primary biventricular support: an analysis of data from the EUROMACS registry.

Objectives: The purpose of this study was to describe pre- and postoperative data from the EUROMACS registry with regard to indications, for and survival and complication rates of patients with primary continuous flow and pulsatile biventricular long-term assist devices (BiVADs) versus total artificial hearts (TAHs) or left ventricular assist devices (LVADs) + short-term right ventricular assist device (RVAD) implants.

Methods: We investigated patients who received implants between 1 January 2011 and 21 October 2017. Clinical baseline information about comorbidities, laboratory results, medical and device therapies and echocardiographic, haemodynamic and right ventricle (RV) parameters were evaluated along with the rates of deaths and complications.

Donor heart selection and outcomes: An analysis of over 2,000 cases.

Background: Decision-making when offered a donor heart for transplantation is complex, and supportive data describing outcomes according to acceptance or non-acceptance choices are sparse. Our aim was to analyze donor heart acceptance decisions and associated outcomes at a single center, and after subsequent acceptance elsewhere.

Methods: This investigation was a retrospective analysis of data obtained from the University of Vienna Medical Center and Eurotransplant centers for the period 2001 to 2015.

Catheter-based edge-to-edge mitral valve repair for pulmonary pressure reduction and to postpone heart transplantation in a teenaged patient.

We report a case of catheter-based edge-to-edge mitral valve repair in a teenage male patient with non-ischaemic cardiomyopathy to improve pulmonary hypertension secondary to severe functional mitral regurgitation (FMR) to defer anticipated heart transplantation. A 19-year-old patient with previous history of fulminant myocarditis followed by markedly left ventricular dysfunction presented with severe mitral regurgitation 3 years after initial recovery. Slightly over time, deterioration of FMR was associated with gradual increase in pulmonary artery pressures despite optimal medical therapy.

MELAS Syndrome and Kidney Disease Without Fanconi Syndrome or Proteinuria: A Case Report.

Mitochondrial encephalomyopathy, lactic acidosis, and stroke-like episodes (MELAS syndrome) represents one of the most frequent mitochondrial disorders. The majority of MELAS cases are caused by m.3243A>G mutation in the mitochondrial MT-TL1 gene, which encodes the mitochondrial tRNA.

[Total artificial heart].

Background: To date the CardioWest™ total artificial heart is the only clinically available implantable biventricular mechanical replacement for irreversible cardiac failure.

Objectives: This article presents the indications, contraindications, implantation procedere and postoperative treatment.

Material And Methods: In addition to a overview of the applications of the total artificial heart this article gives a brief presentation of the two patients treated in our department with the CardioWest™.

[Use of ECMO in adult patients with cardiogenic shock: a position paper of the Austrian Society of Cardiology].

The use of ECMO to stabilize critically ill patients with severely depressed cardiac function and hemodynamics increased in the last years due to broader availability, better performance and easier implantation of the devices. The present guidelines of the Austrian Society of Cardiology focus on the use of ECMO in adult non-operated patients with cardiac diseases. Not only indications and contraindications are highlighted, but also the equally important issues of monitoring, complication management, measures during implantation and operation, and weaning of the devices are treated in detail.

Guillain-Barré Syndrome due to CMV Reactivation after Cardiac Transplantation.

A 40-year-old male patient suffered from end-stage heart failure due to ischemic cardiomyopathy and received orthotopic cardiac transplantation in June 2005. The instantaneous postoperative course was uneventful, but, seven months later, he suffered from paralysis in the lower extremities finally resulting in quadriplegia and was admitted to hospital. After laboratory testings the diagnosis of a Guillain-Barré syndrome due to cytomegalovirus reactivation was confirmed.

Mitochondrial respiratory control and early defects of oxidative phosphorylation in the failing human heart.

Heart failure is a consequence of progressive deterioration of cardiac performance. Little is known about the role of impaired oxidative phosphorylation in the progression of the disease, since previous studies of mitochondrial injuries are restricted to end-stage chronic heart failure. The present study aimed at evaluating the involvement of mitochondrial dysfunction in the development of human heart failure.

Mediastinal liposarcoma.

A 64-year-old male underwent surgical resection of a large liposarcoma of the mediastinum. The management of this unusual tumor is the subject of this case report.

[Evaluation of the potential organ donor with special regards to heart donation].

Regarding limited availability of organ donors for heart transplantation, it is necessary to discuss optimal donor evaluation and donor management. In this manuscript general donor-related parameters as well as heart-specific parameters are discussed regarding international literature. In addition, "marginal" donors and in contrast "optimal" donors are defined.

[Biomarker for diagnosis of rejection after heart transplantation].

Heart transplantation is an established therapeutic modality in patients with end-stage heart failure. In the 1st year after transplantation acute cellular rejection is still important. The diagnosis of acute cellular rejection is based on the histological evaluation of endomyocardial biopsy (EMB) specimens.

Donor hypo- and hypernatremia are predictors for increased 1-year mortality after cardiac transplantation.

Donor hypernatremia is known to be associated with initial graft dysfunction in liver transplantation. Controversial data exist regarding the impact of sodium dysregulation on patient survival after heart transplantation (HTX). The aim of this study was to investigate the influence of donor sodium levels on survival in a large cohort of heart transplant recipients from the Eurotransplant registry.

Cardiac sarcoidosis mimicking arrhythmogenic right ventricular dysplasia.

Isolated manifestation of sarcoidosis in the heart is very rare. The present work describes the case of a 41-year-old woman with ventricular tachycardia and severe symptoms of heart failure in June 2006. Clinical, MRI and echocardiographic findings revealed the diagnosis of an arrhythmogenic right ventricular dysplasia.

Long-term results of high vs. normal impedance ventricular leads on actual (Real-Life) pacemaker generator longevity.

Aim: The long-term effects of high impedance vs. standard impedance pacing leads on actual generator longevity were studied.

Methods And Results: In 40 patients (21 females, age 73 +/- 13 years) with standard dual-chamber pacemaker indication, bipolar standard impedance ventricular leads and high-impedance leads were implanted in a randomized fashion.

Shunt or snare: coronary endothelial damage due to hemostatic devices for beating heart coronary surgery.

Background: Occlusion of coronary arteries during off-pump coronary bypass operations bears the potential for endothelial injury. The aim of this study was to elucidate the effects of hemostatic devices on the beating heart in human coronaries by means of scanning electron microscopy.

Methods: The coronary arteries of 9 patients with dilated cardiomyopathy and 13 with ischemic heart disease undergoing heart transplantation were handled with intracoronary shunts as well as external snaring techniques on a beating heart, after cannulation but before starting cardiopulmonary bypass.

Prolonged but successful weaning from left ventricular assist device after cardiac decompensation due to late-recognized coarctation of the aorta in a toddler.

A 2-year-old boy was presented with late-recognized coarctation of the aorta and pulmonary hypertension due to left ventricular failure. The coarctation was corrected at the day of admission with a good postoperative result. However, weaning from the respirator failed despite multiple drug support due to left ventricular failure.

Zygomycosis and other rare filamentous fungal infections in solid organ transplant recipients.

Fungi cause severe infections in solid organ transplant (SOT) recipients. Recently, a shift towards non-Aspergillus filamentous fungal infections (nAFFI) was noticed. In a series of 2878 SOTs (kidney, pancreas, islets, liver, heart, lung, and bowel) performed between January 1995 and December 2006 at the Innsbruck medical university, eleven cases of nAFFI were diagnosed.

The pediatric mechanical circulatory support program in Innsbruck, Austria, and the impact of such programs on lack of donor hearts in Europe.

Strategy and results of the Innsbruck Mechanical Circulatory Support Program are presented, and the impact of such programs on pediatric heart transplantation (HTX) in Europe is discussed. Venoarterial extracorporeal membrane oxygenation (vaECMO) and ventricular assist devices (VADs) were used in 21 pediatric patients (median age 3.3 years, 2 days to 17 years) for acute heart failure (AHF) following a bridge or bridge-to-bridge strategy.

Prolonged extracorporeal membrane oxygenation-assisted support provides improved survival in hypothermic patients with cardiocirculatory arrest.

Objective: Extracorporeal circulation is considered the gold standard in the treatment of hypothermic cardiocirculatory arrest; however, few centers use extracorporeal membrane oxygenation instead of standard extracorporeal circulation for this indication. The aim of this study was to evaluate whether extracorporeal membrane oxygenation-assisted resuscitation improves survival in patients with hypothermic cardiac arrest.

Methods: A consecutive series of 59 patients with accidental hypothermia in cardiocirculatory arrest between 1987 and 2006 were included.
