Abstract
OBJECTIVES To determine the procedural safety, safety, and efficacy of left atrial appendage (LAA) occlusion in octogenarians. BACKGROUND Elderly patients with atrial fibrillation (AF) often do not receive appropriate anticoagulation. LAA occlusion is an option for patients with AF and contraindications to anticoagulation. Not much is known about the procedural safety and clinical efficacy of LAA occlusion in the very elderly. METHODS A retrospective review of LAA cases at our institution between 2002 and 2013 in patients 80 years of age or older was performed. Demographic, echocardiographic, procedural, and clinical follow-up data were collected. RESULTS Seventy-five cases were attempted in patients 80 years of age or older (average age 83.4 ± 2.8 years, 53.3% males). Hypertension, coronary artery disease, and heart failure were present in 96, 41.3, and 36%, respectively. Mean CHADS2 and CHA2DS-VASc scores were 3.3 and 5.2. Devices used included the WATCHMAN, ACP, PLAATO, Lariat, and Coherex devices, which were attempted in 34.7, 36, 17.3, 5.3, and 5.3%, respectively. Overall procedural success, safety endpoint, and 1-year device efficacy was 90.1, 3.9, and 97.4%, respectively. CONCLUSION LAA closure is a safe and efficacious method of stroke prevention in the very elderly with AF.

Abstract
Aims Takotsubo cardiomyopathy (TTC) remains a potentially life-threatening disease, which is clinically indistinguishable from acute myocardial infarction (MI). Today, no established biomarkers are available for the early diagnosis of TTC and differentiation from MI. MicroRNAs (miRNAs/miRs) emerge as promising sensitive and specific biomarkers for cardiovascular disease. Thus, we sought to identify circulating miRNAs suitable for diagnosis of acute TTC and for distinguishing TTC from acute MI. Methods and results After miRNA profiling, eight miRNAs were selected for verification by real-time quantitative reverse transcription polymerase chain reaction in patients with TTC (n = 36), ST-segment elevation acute myocardial infarction (STEMI, n = 27), and healthy controls (n = 28). We quantitatively confirmed up-regulation of miR-16 and miR-26a in patients with TTC compared with healthy subjects (both, P < 0.001), and up-regulation of miR-16, miR-26a, and let-7f compared with STEMI patients (P < 0.0001, P < 0.05, and P < 0.05, respectively). Consistent with previous publications, cardiac specific miR-1 and miR-133a were up-regulated in STEMI patients compared with healthy controls (both, P < 0.0001). Moreover, miR-133a was substantially increased in patients with STEMI compared with TTC (P < 0.05). A unique signature comprising miR-1, miR-16, miR-26a, and miR-133a differentiated TTC from healthy subjects [area under the curve (AUC) 0.835, 95% CI 0.733–0.937, P < 0.0001] and from STEMI patients (AUC 0.881, 95% CI 0.793–0.968, P < 0.0001). This signature yielded a sensitivity of 74.19% and a specificity of 78.57% for TTC vs. healthy subjects, and a sensitivity of 96.77% and a specificity of 70.37% for TTC vs. STEMI patients. Additionally, we noticed a decrease of the endothelin-1 (ET-1)-regulating miRNA-125a-5p in parallel with a robust increase of ET-1 plasma levels in TTC compared with healthy subjects (P < 0.05). Conclusion The present study for the first time describes a signature of four circulating miRNAs as a robust biomarker to distinguish TTC from STEMI patients. The significant up-regulation of these stress- and depression-related miRNAs suggests a close connection of TTC with neuropsychiatric disorders. Moreover, decreased levels of miRNA125a-5p as well as increased plasma levels of its target ET-1 are in line with the microvascular spasm hypothesis of the TTC pathomechanism.

Abstract
AIMS Dilated cardiomyopathy (DCM) is one of the leading causes for cardiac transplantations and accounts for up to one-third of all heart failure cases. Since extrinsic and monogenic causes explain only a fraction of all cases, common genetic variants are suspected to contribute to the pathogenesis of DCM, its age of onset, and clinical progression. By a large-scale case-control genome-wide association study we aimed here to identify novel genetic risk loci for DCM. METHODS AND RESULTS Applying a three-staged study design, we analysed more than 4100 DCM cases and 7600 controls. We identified and successfully replicated multiple single nucleotide polymorphism on chromosome 6p21. In the combined analysis, the most significant association signal was obtained for rs9262636 (P = 4.90 × 10(-9)) located in HCG22, which could again be replicated in an independent cohort. Taking advantage of expression quantitative trait loci (eQTL) as molecular phenotypes, we identified rs9262636 as an eQTL for several closely located genes encoding class I and class II major histocompatibility complex heavy chain receptors. CONCLUSION The present study reveals a novel genetic susceptibility locus that clearly underlines the role of genetically driven, inflammatory processes in the pathogenesis of idiopathic DCM.

Abstract
Any percutaneously implanted foreign device carries the potential risk of thrombus formation. If a thrombus is detected after device implantation during follow-up, in most cases anticoagulation therapy is sufficient to resolve the thrombus. If the anticoagulation concept fails, surgery has been the only alternative option to remove thrombotic masses. This case of a patient with a large thrombus formation attached to a PFO closure device who denied surgery demonstrates that mechanical percutaneous clot retrieval is feasible with the AngioVac aspiration system (Vortex Medical, Inc., Norwell, MA). © 2013 Wiley Periodicals, Inc.

Abstract
OBJECTIVES To determine predictors of permanent pacemaker (PPM) implantation up to 30 days after transcatheter aortic valve implantation (TAVI) in a prospective multicenter registry. BACKGROUND Conduction disorders requiring PPM implantation are one of the most common complications seen after TAVI. Knowledge about possible predictors may help to decrease the rate of PPM implantations. METHODS In total, 1347 consecutive patients who underwent TAVI in 22 centers were prospectively enrolled in the German transcatheter aortic valve interventions registry. Both Medtronic CoreValve™ and Edwards Sapien™ valves were implanted. Patients with preprocedurally implanted PPM or implantable cardioverter defibrillator were excluded from the analysis (n = 199). Regression analysis of baseline and procedure characteristics of the remaining 1,147 patients was performed. RESULTS Procedural success was achieved in 97.4% of the cases. The rate for PPM after TAVI was 33.7%. The absence of prior valve surgery, the use of Medtronic CoreValve™ prosthesis and the presence of a porcelain aorta were identified as independent predictors for PPM after TAVI. Mortality at 30 days did not differ between patients with or without PPM necessity (6.0% vs. 8.1%, respectively; HR 0.72; CI (0.45-1.16); P = 0.17). CONCLUSIONS PPM is a common postprocedure requirement after TAVI. The absence of prior valve surgery, the implantation of Medtronic CoreValve™ prosthesis, and the presence of a porcelain aorta were independently associated with PPM after TAVI.

Abstract
Dilated cardiomyopathies (DCM) show remarkable variability in their age of onset, phenotypic presentation, and clinical course. Hence, disease mechanisms must exist that modify the occurrence and progression of DCM, either by genetic or epigenetic factors that may interact with environmental stimuli. In the present study, we examined genome-wide cardiac DNA methylation in patients with idiopathic DCM and controls. We detected methylation differences in pathways related to heart disease, but also in genes with yet unknown function in DCM or heart failure, namely Lymphocyte antigen 75 (LY75), Tyrosine kinase-type cell surface receptor HER3 (ERBB3), Homeobox B13 (HOXB13) and Adenosine receptor A2A (ADORA2A). Mass-spectrometric analysis and bisulphite-sequencing enabled confirmation of the observed DNA methylation changes in independent cohorts. Aberrant DNA methylation in DCM patients was associated with significant changes in LY75 and ADORA2A mRNA expression, but not in ERBB3 and HOXB13. In vivo studies of orthologous ly75 and adora2a in zebrafish demonstrate a functional role of these genes in adaptive or maladaptive pathways in heart failure.

Abstract
Carotid stenting has become a commonly used procedure for the treatment of carotid artery stenosis. Though equipment and techniques have improved tremendously over the recent 3 decades, complications do occur. It is important for carotid operators to be familiar with potential complications and adverse events. In this article complications and adverse events of carotid stenting including those that are related to the vascular access site, vessel spasm, dissection, perforation, thrombotic occlusion and hemodynamic instability and arrhythmias are reviewed. In addition, management strategies are discussed.

Abstract
Periprosthetic fractures are a challenging problem in view of the demographic development and the increasing number of implanted prostheses. Most of these fractures occur postoperatively after a period of two to four years after implantation of a total knee arthroplasty. They are usually caused by traumata, implantation-specific factors and loosening of the prosthesis. Beside further risk factors osteopenia and a reduced mobility of the prosthesis predispose to these fractures. Numerous classifications which also include a loosening of the prosthesis in the fracture discription are an important tool for planning the therapy. Beside the conservative treatment, the stabilization of the fracture or changing the prosthesis should be considered. The treatment options of periprosthetic fractures of the knee joint are discussed in view of different initial situations with the aim of achieving a load-stable situation.

Abstract
BACKGROUND Patent foramen ovale (PFO) with right-to-left shunt has a prevalence of 10% to 34% in the general population. It can cause an ischemic stroke, transient ischemic attack, and paradoxical peripheral or coronary embolization. Its influence on migraine and several other diseases and conditions is currently under debate. Attention has recently been turned to the correlation between PFO and obstructive sleep apnea. Thus far, studies on the prevalence of right-to-left shunts as a surrogate for PFO in these patients were limited by small sample sizes and the results have been conflicting. Here, we evaluate the prevalence of right-to-left shunting (RLS) through transcranial Doppler ultrasound (TCD) in a large patient group with obstructive sleep apnea (OSA). METHODS One hundred consecutive patients (mean age 59.5 y) with OSA underwent TCD with intravenous injection of agitated saline. The grading of right-to-left-shunts was in accordance with the Spencer PFO Grading Scale. RESULTS RLS was detected in 72 of 100 patients (72%). Thirty-four out of these 72 patients (47%) had a shunt grade I or II; 15 (21%) had a shunt Grade III or IV; and 23 (32%) had a large shunt (Grade V or V+). In 47 of 72 patients (65%), a right-to-left shunt was detectable at rest without Valsalva maneuver. CONCLUSION The prevalence of a RLS in patients with OSA is high. Provided other intracardiac or pulmonary shunts were absent, the high prevalence of a RLS suggests a high prevalence of PFO in patients with OSA.
