In eight piglets (mean age 15 weeks, weight 15-20 kg), 30 cryolesions (three consecutive freeze-thaw cycles) were applied to the atrial aspect of both AV valve annuli (n = 18) as well as to ventricular myocardium below the valves (n = 12). Coronary angiography was performed before and after cryoenergy application. The animals were reevaluated by coronary angiography and intracoronary ultrasound (ICUS) after 48 h. All hearts were removed for histological examination of the lesions subsequently. After staining (hematoxylin-eosin, desmin immunohistochemistry), lesions was measured by planimetry with a digital virtual miscroscope analysis system and volumes of the cryolesions were calculated. Mean atrial lesion volume was 190.68 +/- 167.53 mm(3) (n = 18), and mean ventricular lesion volume was 184.34 +/- 107.42 mm(3) (n = 12). Compared with previously reported data on lesion volumes after single and double freeze-thaw cycles, lesions were significantly larger. Coronary arteries were unaffected on coronary angiography as well as on ICUS. No affection of coronary arteries was found on histological examination.

Experience with internal cardioverter defibrillator (ICD) therapy in this population is limited. We conducted a multicenter cohort study to determine the current state of ICD therapy in individuals after atrial baffle procedure. MethodsDemographic and clinical data as well as data on device implantation, programming, ICD discharges, and complications after atrial baffle procedure for d-TGA from four German centers were analyzed retrospectively. ResultsICD implantation was undertaken in 33 subjects. ICD implantation was undertaken as primary prevention in 29 (88%) and secondary prevention in four (12%) individuals. There were 21 (64%) subjects with atrial reentrant tachycardia (IART). During a median follow-up of 4.8 years, seven appropriate ICD therapies were delivered in three (10%) individuals with primary prevention indication. No appropriate shocks were documented in subjects with secondary prevention indication. A total of 12 inappropriate ICD discharges occurred in eight (24%) individuals due to IART (n = 6) or lead failure (n = 2). ICD-related complications were noted in seven individuals (21%): lead dislodgement/failure in five (15%) and ICD infection in two subjects (6%). ConclusionsThe majority of individuals received an ICD for primary prevention of SCD, thus representing a liberal attitude of physicians for ICD implantation. During a median follow-up of 4.8 years, the rate of appropriate ICD therapies was low and clearly exceeded by inappropriate ICD discharges. Lead failure and IART were present in >20% of the individuals and were frequent reasons for inappropriate ICD discharges.

Aim of this study was to investigate the feasibility of epicardial pacing with a leadless pacemaker in a lamb model. Animals and methods Seventeen lambs underwent epicardial implantation of a Micra transcatheter pacing system (TPS) (Medtronic, Minneapolis, MN, USA) via left‐lateral thoracotomy to the left ventricle (LV) surface (n = 11/17) and to the left atrial appendage (n = 6). Ventricular devices were fixated with the tines within the pericardium, whereas the tines of the atrial devices penetrated the myocardium of the left atrial appendage. After 31 weeks, animals were sacrificed and hearts were explanted for histological analysis. Results Following implantation, median P/R amplitude was 4.25/5.5 mV while median pacing threshold was 1.1/1.9 V at 0.24 ms. After 31 weeks, median P/R amplitude was 3.3/4.2 mV. Median atrial pacing threshold was 0.5/0.24 ms. Eight of 10 ventricular pacemakers had lost capture at standard impulse width even at maximum impulse amplitude. On explantation, firm adhesion of the device to the thoracic wall and dislodgement of the electrode tip was found in those ventricular devices. Conclusions Firm fixation of the Micra electrode to the epicardial surface as applied to the atrial devices resulted in excellent electrical properties during midterm follow up. Pericardial fixation as in the ventricular devices was associated with loss of capture. Therefore, it is important to embed the tines in the myocardium and to choose an alternative implantation site allowing for safe fixation of the Micra TPS in a position perpendicular to ventricular epimyocardium."],["dc.description.sponsorship","Medtronic http://dx.doi.org/10.13039/100004374"],["dc.identifier.doi","10.1111/pace.14067"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/84052"],["dc.language.iso","en"],["dc.notes.intern","DOI Import GROB-399"],["dc.relation.eissn","1540-8159"],["dc.relation.issn","0147-8389"],["dc.rights","This is an open access article under the terms of the Creative Commons Attribution‐NonCommercial‐NoDerivs License, which permits use and distribution in any medium, provided the original work is properly cited, the use is non‐commercial and no modifications or adaptations are made."],["dc.title","Epicardial implantation of a leadless pacemaker in a lamb model"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dspace.entity.type","Publication"]]

However, almost no data exists on the use of this technology in catheter ablation of intraatrial reentrant tachycardia in patients with congenital heart disease. The aim of the present study was to evaluate the impact of contact force monitoring during catheter ablation of intraatrial reentrant tachycardia in those patients. Methods Catheter ablation of intraatrial reentrant tachycardia using monitoring of catheter contact force was performed in 28 patients with congenital heart disease (CHD). Thirty-two patients matched according to gender, age, and body weight with congenital heart disease undergoing catheter ablation without contact force monitoring served as control group. Parameters reflecting acute procedural success, long-term efficacy, and safety were compared. Results Acute procedural success was statistically not different in both groups (contact force 93 % vs. control 84 %, p = 0.3). Likewise the recurrence rate 1 year after ablation as shown by Kaplan-Meier analysis did not differ (contact force 28 % vs. control 37 %, p = 0.63). Major complications were restricted to groin vessel injuries and occurred in 3 out of 60 patients (contact force n= 1; control n = 2). Complications related to excessive catheter contact force were not observed. Conclusion The present study did not show superiority of catheter contact force monitoring during ablation of intraatrial reentrant tachycardia in patients with CHD in terms of efficacy and safety. Higher contact force compared to pulmonary vein isolation might therefore be required to increase the efficacy of catheter ablation of intraatrial reentrant tachycardia in patients with congenital heart disease."],["dc.identifier.doi","10.1007/s10840-015-0096-z"],["dc.identifier.isi","000384843600016"],["dc.identifier.pmid","26743070"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/39914"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Springer"],["dc.relation.issn","1572-8595"],["dc.relation.issn","1383-875X"],["dc.title","Contact force monitoring during catheter ablation of intraatrial reentrant tachycardia in patients with congenital heart disease"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]

We report our experience in transbaffle access (TBA) to the PVA for ablation of atrial re-entrant tachycardia focusing on technical details. Methods and results In eight patients, six after Mustard procedure and two with a Fontan circulation, endocardial mapping of atrial re-entrant tachycardia revealed the critical part of the re-entry circuit within the PVA. A total of 10 ablation procedures were performed. Detailed angiographic assessment of the anatomy of the systemic and pulmonary venous atria was performed prior to baffle puncture. Transbaffle access was successfully established with a standard transseptal needle in 9 of 10 procedures. No major complications occurred. At the end of the procedure and the removal of the transseptal sheath, there was no residual shunt in any patient. Conclusion Transbaffle access to the PVA for ablation of atrial re-entrant tachycardia is feasible, less invasive than alternative approaches and can be safely applied in patients after Mustard procedure or with a Fontan circulation.
