Objectives: To evaluate at 1.5 and 3 T MRI the safety and performance of trademarked ENO, TEO, or OTO pacing systems with automated MRI Mode and the image quality of non-enhanced MR examinations.

Methods: A total of 267 implanted patients underwent MRI examination (brain, cardiac, shoulder, cervical spine) at 1.

Evolutionary lability in floral ontogeny affects pollination biology in Trimezieae.

Premise: There is little direct evidence linking floral development and pollination biology in plants. We characterize both aspects in plain and ornamented flowers of Trimezieae (Iridaceae) to investigate how changes in floral ontogeny may affect their interactions with pollinators through time.

Methods: We examined floral ontogeny in 11 species and documented pollination biology in five species displaying a wide range of floral morphologies.

Trends beyond the new normal: from remote monitoring to digital connectivity.

COVID pandemic emergency has forced changes from traditional in-person visits to application of telemedicine in order to overcome the barriers and to deliver care. COVID-19 has accelerated adoption of digital health. During this time, the distance is itself a prevention tool and the use of technology to deliver healthcare services and information has driven the discovery of mobile and connected health services.

State-of-the-art consensus on non-transvenous implantable cardioverter-defibrillator therapy.

Within the last decade, implantable cardioverter-defibrillator (ICD) systems with non-transvenous leads were developed in order to minimize complications related to the cardiovascular position of transvenous ICD leads. This national expert consensus gives an overview of potential indications for the implantation of non-transvenous ICD systems, and provides specific recommendations for implantation, follow-up, and complication management in patients with subcutaneous ICD. Regarding particular issues like the necessity for shock efficacy testing, or the clinical outcome as compared to transvenous ICD, randomized data are expected in the near future.

State of the art: leadless ventricular pacing : A national expert consensus of the Austrian Society of Cardiology.

Background: Cardiac pacing has been shown to improve quality of life and prognosis of patients with bradycardia for almost 60 years. The latest innovation in pacemaker therapy was miniaturization of generators to allow leadless pacing directly in the right ventricle. There is a long history and extensive experience of leadless ventricular pacing in Austria.

Floral uniformity through evolutionary time in a species-rich tree lineage.

Changes in floral morphology are expected across evolutionary time and are often promoted as important drivers in angiosperm diversification. Such a statement, however, is in contrast to empirical observations of species-rich lineages that show apparent conservative floral morphologies even under strong selective pressure to change from their environments. Here, we provide quantitative evidence for prolific speciation despite uniform floral morphology in a tropical species-rich tree lineage.

Case of nasogastric tube dysfunction.

Clinical Presentation: An elderly female patient was admitted to intensive care for prolonged vasopressor therapy and mechanical ventilation after cardiac arrest and acute percutaneous coronary intervention. Antiplatelet, thyroid hormone replacement and statin therapies were administered through a 14-French nasogastric tube (Nestlé Health Science) and enteral feeding was initiated. Correct position of the nasogastric tube was confirmed radiologically.

Floral heterochrony promotes flexibility of reproductive strategies in the morphologically homogeneous genus Eugenia (Myrtaceae).

Background And Aims: Comparative floral ontogeny represents a valuable tool to understand angiosperm evolution. Such an approach may elucidate subtle changes in development that discretely modify floral architecture and underlie reproductive lability in groups with superficial homogeneous morphology. This study presents a comparative survey of floral development in Eugenia (Myrtaceae), one of the largest genera of angiosperms, and shows how previously undocumented ontogenetic trends help to explain the evolution of its megadiversity in contrast to its apparent flower uniformity.

Myrteae phylogeny, calibration, biogeography and diversification patterns: Increased understanding in the most species rich tribe of Myrtaceae.

Myrteae (c. 2500 species; 51 genera) is the largest tribe of Myrtaceae and an ecologically important groups of angiosperms in the Neotropics. Systematic relationships in Myrteae are complex, hindering conservation initiatives and jeopardizing evolutionary modelling.

Flower development of Goniorrhachis marginata reveals new insights into the evolution of the florally diverse detarioid legumes.

Background And Aims: The study of floral morphology and ontogeny and the re-investigation of existing data help to uncover potential synapomorphic characters and foster our understanding of phylogenetic relationships that rely primarily on molecular analyses. Goniorrhachis marginata is a monotypic caesalpinioid legume (Leguminosae) that shows some interesting floral features, such as a long hypanthium and regular Rosaceae-like flowers. We studied the ontogeny and morphology of the flowers in detail and present our results in a broad phylogenetic context.

A molecular-dated phylogeny and biogeography of the monotypic legume genus Haplormosia, a missing African branch of the otherwise American-Australian Brongniartieae clade.

A comprehensively sampled reassessment of the molecular phylogeny of the genistoid legumes questions the traditional placement of Haplormosia, an African monotypic genus traditionally classified within tribe Sophoreae close to the Asian-American geographically disjunct genus Ormosia. Plastid matK sequences placed Haplormosia as sister to the American-Australian tribe Brongniartieae. Despite a superficial resemblance between Haplormosia and Ormosia, a re-examination of the morphology of Haplormosia corroborates the new phylogenetic result.

Molecular systematics of the Amazonian genus Aldina, a phylogenetically enigmatic ectomycorrhizal lineage of papilionoid legumes.

Aldina (Leguminosae) is among the very few ecologically successful ectomycorrhizal lineages in a family largely marked by the evolution of nodulating symbiosis. The genus comprises 20 species predominantly distributed in Amazonia and has been traditionally classified in the tribe Swartzieae because of its radial flowers with an entire calyx and numerous free stamens. The taxonomy of Aldina is complicated due to its poor representation in herbaria and the lack of a robust phylogenetic hypothesis of relationship.

Flowers of the early-branching papilionoid legume Petaladenium urceoliferum display unique morphological and ontogenetic features.

Premise Of The Study: Floral development can help to shed light on puzzling features across flowering plants. The enigmatic Amazonian monospecific genus Petaladenium of the legume family (Leguminosae) had rarely been collected and only recently became available for ontogenetic studies. The fimbriate-glandular wing petals of P.

Filling in the gaps of the papilionoid legume phylogeny: the enigmatic Amazonian genus Petaladenium is a new branch of the early-diverging Amburaneae clade.

Recent deep-level phylogenies of the basal papilionoid legumes (Leguminosae, Papilionoideae) have resolved many clades, yet left the phylogenetic placement of several genera unassessed. The phylogenetically enigmatic Amazonian monospecific genus Petaladenium had been believed to be close to the genera of the Genistoid Ormosieae clade. In this paper we provide the first DNA phylogenetic study of Petaladenium and show it is not part of the large Genistoid clade, but is a new branch of the Amburaneae clade, one of the first-diverging lineages of the Papilionoideae phylogeny.

Low incidence of coronary angiography in the evaluation process of the potential heart donor.

Introduction: We investigated the practice of coronary angiography (CA) on donor hearts.

Patients And Methods: Between January 1, 2000, and December 31, 2010, all reported organ donors aged <66 years were analyzed retrospectively. Donor charts were evaluated regarding a performed CA, its outcome, the timing of CA during the evaluation process, and reasons for organ refusal.

Comparative development of rare cases of a polycarpellate gynoecium in an otherwise monocarpellate family, Leguminosae.

Premise Of The Study: Apocarpy (i.e., free carpels) is considered to be the basal condition for ovary development in angiosperms.

The role of serum albumin in the prediction of malnutrition in patients at least five yr after heart transplantation.

Objectives: Malnutrition after heart transplantation (HTX) is related to graft sclerosis. The risk for malnutrition is often underestimated by conventional measurements. We aimed to compare these with objective assessors for malnutrition.

Socio-economic effects and cost saving potential of remote patient monitoring (SAVE-HM trial).

Objective: In the SAVE-trial we evaluated the safety, reliability and improvements of patient management using the BIOTRONIK Home Monitoring®-System (HM) in pacemaker (PM) and implanted cardioverter defibrillator (ICD) patients.

Design: 115 PM (Module A) and 36 ICD-patients (Module B) were recruited 3 months after implantation.

Patients: 65 patients in Module A were randomised to HM-OFF and had one scheduled outpatient clinic follow-up(FU) per year, whereas patients randomised to HM-ON were equipped with the mobile transmitter and discharged without any further scheduled in-office FU.

[Successful preclinical thoracotomy in a 17-year-old man].

We report the case of a 17-year-old man who sustained multiple stab wounds after a knife attack. After arrival of the emergency medical team the patient suffered a cardiac arrest caused by cardiac tamponade. After emergency thoracotomy and open heart massage the patient developed ROSC and could be discharged 13 days later without neurological deficits.

Complication profile of the Berlin Heart EXCOR biventricular support in children.

In chronic cardiomyopathy, mechanical circulatory support (MCS) plays an increasingly important role for children as the shortage of suitable donor hearts increases waiting time on the transplant list. We report our experience with the paracorporal Berlin Heart EXCOR System (Berlin Heart AG, Berlin, Germany) used as a biventricuclar assist device (BVAD). Nine patients with a BVAD EXCOR system were treated between 2006 and 2012; out of these patients, four were less than 18 years old (6, 14, 14, and 17 years old).

Papilionoid inflorescences revisited (Leguminosae-Papilionoideae).

Background And Aims: The inflorescence structure determines the spatiotemporal arrangement of the flowers during anthesis and is therefore vital for reproductive success. The Leguminosae are among the largest angiosperm plant families and they include some important crop plants. In papilionoid legumes, the raceme is the most common type of inflorescence.

Prehospital care of left ventricular assist device patients by emergency medical services.

Left ventricular assist devices (LVADs) are frequently implanted as permanent (bridge to destination [BTD]) or temporary (bridge to transplantation [BTT]) cardiac support. When LVAD patients are discharged to home, they are very likely to require emergency medical services (EMS), but there is very little literature on out-of-hospital emergency care for patients with LVADs. We present two typical cases of LVAD patients for whom EMS was called.

Everolimus in different combinations as maintenance immunosuppressive therapy in heart transplant recipients.

Objectives: We examined the experiences of heart transplant recipients receiving everolimus as maintenance therapy in different combinations over a long time.

Materials And Methods: Between 2004 and 2009, forty patients (29 men, 11 women; mean age, 51.6 y) were switched from a routine immunosuppressive regimen to everolimus.

Radiation induced cutaneous ulcer on the back in a patient with congenital anomaly of the upper cava system.

Recent years have seen the introduction of a number of additive diagnostic and therapeutic procedures in invasive cardiology. Cardiac catheterization procedures using fluoroscopy reduce patient morbidity and mortality compared to conventional surgical interventions. The associated radiation exposure for the patient is, however, often underestimated, while implantation of cardiac resynchronization therapy (CRT) and/or implantable cardioverter defibrillator (ICD) pacemaker systems sometimes entails even higher radiation exposures due to prolonged fluoroscopic studies.
