3D transvenous radiofrequency ablation of manifest epicardial posterior-septal accessory pathways in children: Can technology innovations improve the outcome?

Introduction: The aim of the study was to revise our more recent experience about epicardial posterior-septal accessory pathways radiofrequency transcatheter ablation in children and young patients using a transvenous approach through the coronary sinus, to understand if new mapping and ablation technologies can increase success rate and safety. Methods and results: Twenty children (mean age 13 ± 3 years) with epicardial posterior-septal accessory pathways (14 in coronary sinus and 6 in the middle cardiac vein) underwent radiofrequency transcatheter ablation with CARTO-3® system with help of the CARTO-Univu® module. Acute success rate was 73%. No patient was lost to follow-up (mean time 11.4 ± 9 months). The recurrence rate was 19%. Two patients underwent a successful redo-procedure; the overall long-term success rate was 65%. Navistar® catheter presented the highest acute success rate in the coronary sinus. Navistar SmartTouch® was the only catheter that did not present recurrences after the acute success, and it was successfully used in two patients previously unsuccessfully treated with a Navistar ThermoCool®. Acute success rate was 79% without image integration with angio-CT, while it was 63% after the introduction of CARTO-Merge®. Conclusion: Epicardial posterior-septal accessory pathways can be definitively eliminated by transvenous radiofrequency transcatheter ablation in more than half of the cases in children. Acute success rate does not seem to depend on catheters used, but contact-force catheter seems to be useful in cases with recurrences. Image integration with cardiac-CT does not increase success rate, but it is useful to detect coronary sinus alterations to better guide ablation strategy.

Multimodal Image Integration for Epilepsy Presurgical Evaluation: A Clinical Workflow

Multimodal image integration (MMII) is a promising tool to help delineate the epileptogenic zone (EZ) in patients with medically intractable focal epilepsies undergoing presurgical evaluation. We report here the detailed methodology of MMII and an overview of the utility of MMII at the Cleveland Clinic Epilepsy Center from 2014 to 2018, exemplified by illustrative cases. The image integration was performed using the Curry platform (Compumedics Neuroscan™, Charlotte, NC, USA), including all available diagnostic modalities such as Magnetic resonance imaging (MRI), Positron Emission Tomography (PET), single-photon emission computed tomography (SPECT) and Magnetoencephalography (MEG), with additional capability of trajectory planning for intracranial EEG (ICEEG), particularly stereo-EEG (SEEG), as well as surgical resection planning. In the 5-year time span, 467 patients underwent MMII; of them, 98 patients (21%) had a history of prior neurosurgery and recurring seizures. Of the 467 patients, 425 patients underwent ICEEG implantation with further CT co-registration to identify the electrode locations. A total of 351 patients eventually underwent surgery after MMII, including 197 patients (56%) with non-lesional MRI and 223 patients (64%) with extra-temporal lobe epilepsy. Among 269 patients with 1-year post-operative follow up, 134 patients (50%) had remained completely seizure-free. The most common histopathological finding is focal cortical dysplasia. Our study illustrates the usefulness of MMII to enhance SEEG electrode trajectory planning, assist non-invasive/invasive data interpretation, plan resection strategy, and re-evaluate surgical failures. Information presented by MMII is essential to the understanding of the anatomo-functional-electro-clinical correlations in individual cases, which leads to the ultimate success of presurgical evaluation of patients with medically intractable focal epilepsies.

Treatment of symptomatic atrial tachycardia in complex anatomic conditions: use and outcome of ablation in patients after damus-kaye-stansel surgery

Funding Acknowledgements Type of funding sources: None. Background Atrial tachycardias (AT) are amongst the most frequent complications in adult patients with congenital heart disease (ACHD). Their incidence mainly depends on age and complexity of underlying defect. AT has a marked impact on morbidity and mortality and is associated with sudden cardiac death particularly in complex ACHD patients. The arrhythmic substrate can be variable from re-entry to multifocal resulting in demanding requirements for electrophysiologic ablation procedures (EP) and thus, relatively high rates of recurrence. Methods and results Retrospective analysis of ACHD patients with prior Damus-Kaye-Stansel (DKS) surgery treated at one of the largest specialized tertiary centers for ACHD patients worldwide. Analysis focussed on occurrence of AT, respective treatment and outcome of EP. Over a median observation time of 15 years, 13 patients with prior DKS surgery and complex congenital heart defects of different types but uniformly Fontan circulation, were identified (median age 22.0 years (IQR 20.5 – 25.5), 76.9% male, 92.3% NYHA Class I, median systemic ventricular ejection fraction 58.5%, 69.2% extracardiac tunnel). Seven patients (53.8%) presented with symptomatic AT (median cyclic length 440 ms (IQR 360.0 – 517.5)). Of these, six patients underwent EP. Median procedure time was 180.5 min (IQR 160.8 – 274.5), median fluoroscopy time 1.56 min (IQR 0.51 – 4.73) and radiofrequency time 851 sec (265.0 -2005.0). Remote magnetic navigation was used to access ablation site through a retrograde access via the aortic as well as the neo-aortic valve. Three-dimensional image integration aided in mapping and ablation. Throughout the procedure as well as in follow-up visits, no reportable complications were observed. After a mean of 1.5 procedures, all analysed patients stayed complaint-free throughout a median time-interval of 13 months. Conclusion AT are frequent in complex univentricular situations after Damus-Kaye-Stansel surgery (53.8%). Although more than one procedure (mean 1.5) was necessary to achieve satisfactory results even in experienced hands, EP appears to be an appropriate treatment strategy in this young and otherwise healthy patient cohort. According to our analysis, EP is feasible and safe in centers with knowledge of specific anatomic characteristics of congenital heart disease and when the appropriate technical infrastructure is present. Access to ablation site was performed by remote magnetic navigation in the majority of procedures. The floppy catheter was navigated through the neo-aortic as well as through the aortic valve without observable peri- or postinterventional complications. Mapping with three-dimensional image integration facilitated EP and led to a relatively low radiation exposure with the known benefits for the patient as well as for the healthcare professionals involved in the procedure.

Visualisation of Jenkins Pipelines

Continuous Integration (CI) is an essential approach in modern software engineering. CI tools help merging the recent commits from the developers, thus the bugs can be realized in an early phase of development and integration hell can be avoided. Jenkins is the most well-known and most widely-used CI tool. Pipelines become first-class citizen in Jenkins 2. Pipelines consist of stages, such as compiling, building Docker image, integration testing, etc. However, comprehensive Jenkins pipelines are hard to see through and understand. In this paper, we argue for a modern visualisation of Jenkins pipelines. We present our solution for making Jenkins pipelines comprehensible on the dashboard.
