    Title translation Benefits of cardiac magnetic resonance diagnostics in patients with heart rhythm disorders : From risk stratification to interventional procedures.
    Abstract Cardiac magnetic resonance imaging (cMRI) now rates among the established diagnostic procedures for the clarification of cardiac disease patterns. In modern clinical electrophysiology, apart from providing basic cardiac diagnostics of patients prior to interventional procedures, the imaging method enables the three-dimensional reconstruction of cardiac target structures of the planned ablation procedure, which can significantly improve the safety and efficacy of the intervention. Furthermore, cMRI has a high significance with respect to risk stratification during implantable cardioverter defibrillator (ICD) evaluation. In addition to an exact determination of ventricular function, its capability for detailed tissue characterization enables the visualization and quantification of fibrotic lesions and scar tissue as potential arrhythmogenic triggers. This anatomic assignment also enables an increased accuracy of the ablation of substrate-based arrhythmia. In comparison to this the interventional cMRI as a direct interface between cMRI and invasive electrophysiology represents a comparably new field of application. Initial clinical experiences in the field of ablation of typical atrial fibrillation could not only confirm the feasibility of the concept but also enabled recognition of the clear advantages of an imaging-guided electrophysiological procedure.

    Title translation MRI-based catheter ablation : Current status and outlook.
    Abstract Fluoroscopy-based catheter ablation has established itself as a standard procedure for the treatment of patients with cardiac arrhythmias. However, it is subject to certain limitations with regard to the visualization of arrhythmogenic substrate and ablation lesions and is associated with radiation exposure. Within the framework of studies, initial experience with MRI-based, radiation-free electrophysiological examinations and ablations could be gained. The integration of MRI technology into electrophysiological procedures promises numerous advantages. The ability to operate in a radiation-free environment during MRI-based catheter ablation is significant and promising. Furthermore, MRI provides important procedure-relevant information in terms of visualization of individual arrhythmogenic substrate. In order to further improve immediate and long-term ablation success, especially in the context of complex arrhythmias and structural heart disease, the direct and successful integration of MRI-generated findings into the ablation process is of utmost importance. The future of MRI-based catheter ablation could thus lie in particular in the treatment of more complex cardiac arrhythmias, which require personalized therapy paths. In this respect, however, the data situation is still extremely limited. Further technical developments and larger studies are indispensable in order to gain further important insights into the feasibility, safety and success rate of MRI-based invasive electrophysiological diagnostics and therapy in comparison to conventional ablation methods.

    Abstract Background: Tunnelled haemodialysis catheters are commonly used to perform haemodialysis. Rare complications of these catheters include perforations of major blood vessels or the heart. Albeit rare, these complications can lead to significant morbidity and mortality.
    Case summary: We present a case of late migration of a tunnelled haemodialysis catheter causing a right atrial perforation with subsequent pericardial tamponade, haemodynamic shock, and cardiac arrest. A 51-year-old female patient with end-stage renal disease presented with hypotension and lactate acidosis, indicating circulatory shock, during ambulatory intermittent haemodialysis. Dialysis was performed through a tunnelled haemodialysis catheter that had been implanted more than 1 year ago. Upon admission to the hospital, initial diagnostics, including transthoracic echocardiography and computed tomography scan, showed a circumferential pericardial effusion which was not haemodynamically significant and no other pathological findings. After being transferred to the intensive care unit, the patient again showed signs of haemodynamic shock at the start of another dialysis session which deteriorated to cardiac arrest. Ultimately, using multi-modality imaging, migration of the catheter tip through the right atrial wall into the pericardial space was diagnosed. Emergency sternotomy and surgical extraction of the tunnelled haemodialysis catheter were performed and the patient recovered completely.
    Discussion: Migration and perforation of a tunnelled haemodialysis catheter can occur late after implantation and lead to circulatory shock, thus requiring immediate diagnostic workup and surgical therapy. Routine diagnostic procedures may be insufficient for making a correct diagnosis. More specific approaches, such as multi-modality imaging including contrast echocardiography, should be implemented upon clinical suspicion.

    Abstract Fully CMR-guided electrophysiological interventions (EP-CMR) have recently been introduced but data on the optimal CMR imaging protocol are scarce. This study determined the clinical utility of 3D non-selective whole heart steady-state free precession imaging using compressed SENSE (nsWHcs) for automatic segmentation of cardiac cavities as the basis for targeted catheter navigation during EP-CMR cavo-tricuspid isthmus ablation. Fourty-two consecutive patients with isthmus-dependent right atrial flutter underwent EP-CMR radiofrequency ablations. nsWHcs succeeded in all patients (nominal scan duration, 98 ± 10 s); automatic segmentation/generation of surface meshes of right-sided cavities exhibited short computation times (16 ± 3 s) with correct delineation of right atrium, right ventricle, tricuspid annulus and coronary sinus ostium in 100%, 100%, 100% and 95%, respectively. Point-by-point ablation adhered to the predefined isthmus line in 62% of patients (26/42); activation mapping confirmed complete bidirectional isthmus block (conduction time difference, 136 ± 28 ms). nsWHcs ensured automatic and reliable 3D segmentation of targeted endoluminal cavities, multiplanar reformatting and image fusion (e.g. activation time measurements) and represented the basis for precise real-time active catheter navigation during EP-CMR ablations of isthmus-dependent right atrial flutter. Hence, nsWHcs can be considered a key component in order to advance EP-CMR towards the ultimate goal of targeted substrate-based ablation procedures.

    Abstract The processes of seawater intrusion, groundwater abstraction and disposal of high concentrated effluents from desalinization plants (DSP) were investigated in a coastal aquifer on the Red Sea coast of El Gouna, Egypt. The feeding wells (depths from 20 to 150 m), the product water and the residual brines of three desalinization plants were sampled for chemical analysis and were partially sampled for stable isotopes analysis (δ18O and δ2H in H2O).The wells in the aquifer abstract mixtures of brackish groundwater (total dissolved solids TDS 5–15 g/l) and seawater from the Red Sea (TDS 42–44 g/l) that intrudes into the coastal aquifers. Primary mixing rates were determined by means of the Br/Cl ratio and ranged from 5% to >90% seawater. The disposal of the highly concentrated residual brines from the DSPs via infiltration/injection into the used aquifer causes a locally strong increase in the salinization of the groundwater (up to 60 g/l TDS, significantly above seawater concentration) in wells that are actually feeding the DSPs (containing up to 60% brine). The influence of the brines on the groundwater could also be identified by the Br/Cl ratio in relation to salinization. Conversely, the primary source (the mixing ratio groundwater-seawater) of the brines from the DSP could also be identified by Br/Cl ratio and stable isotopes (δ18O and δ2H in H2O), which behave as conservative tracers in the reverse osmosis processes in the DSP.The brackish groundwater shows partially gypsum saturation and supersaturation. Mixing of this groundwater with seawater additionally increases the sulphate concentration and cation exchange processes and especially the calcium concentration. The abstracted groundwater and groundwater-seawater mixtures therefore have a high potential for sulphate scaling. Calcite, as the second important phase for scaling, is generally supersaturated in groundwater, seawater and the mixtures. Consequently, the brines that are produced from these waters are highly supersaturated with respect to gypsum and calcite.The injection/infiltration of these brines into the aquifers leads to extended zones of groundwater with increased salinity and saturation/supersaturation in respect to gypsum and probably intense gypsum precipitation.
