Background Data on Device-related Thrombus (DRT) after left atrial appendage closure (LAAC) remain scarce. This study aimed to investigate risk factors for DRT from centers reporting to the EUROC-DRT registry. Methods We included 537 patients (112 with DRT and 425 without DRT) who had undergone LAAC between 12/2008 and 04/2019. Baseline and implantation characteristics, anti-thrombotic treatment and clinical outcomes were compared between both groups in uni- and multivariate analyses. Additional propensity-score matching (PSM) was conducted to focus on the role of implantation characteristics. Results Patients with DRT showed higher rates of previous stroke/transient ischemic attack (TIA) (49.1% vs. 34.7%, p < 0.01), spontaneous echocardiographic contrast (SEC) (44.9% vs. 27.7%, p < 0.01) and lower left atrial appendage (LAA) peak emptying velocity (35.4 +/- 18.5 vs. 42.4 +/- 18.0 cm/s, p= 0.02). Occluders implanted in DRT patients were larger (25.5 +/- 3.8 vs. 24.6 +/- 3.5 mm, p =0.03) and implanted deeper in the LAA (mean depth: 7.6 +/- 4.7 vs. 5.7 +/- 4.7 mm, p

BACKGROUND The role of direct oral anticoagulants as compared with vitamin K antagonists for atrial fibrillation after successful transcatheter aortic-valve replacement (TAVR) has not been well studied. METHODS We conducted a multicenter, prospective, randomized, open-label, adjudicator-masked trial comparing edoxaban with vitamin K antagonists in patients with prevalent or incident atrial fibrillation as the indication for oral anticoagulation after successful TAVR. The primary efficacy outcome was a composite of adverse events consisting of death from any cause, myocardial infarction, ischemic stroke, systemic thromboembolism, valve thrombosis, or major bleeding. The primary safety outcome was major bleeding. On the basis of a hierarchical testing plan, the primary efficacy and safety outcomes were tested sequentially for noninferiority, with noninferiority of edoxaban established if the upper boundary of the 95% confidence interval for the hazard ratio did not exceed 1.38. Superiority testing of edoxaban for efficacy would follow if noninferiority and superiority were established for major bleeding. RESULTS A total of 1426 patients were enrolled (713 in each group). The mean age of the patients was 82.1 years, and 47.5% of the patients were women. Almost all the patients had atrial fibrillation before TAVR. The rate of the composite primary efficacy outcome was 17.3 per 100 person-years in the edoxaban group and 16.5 per 100 person-years in the vitamin K antagonist group (hazard ratio, 1.05; 95% confidence interval [CI], 0.85 to 1.31; P���=���0.01 for noninferiority). Rates of major bleeding were 9.7 per 100 person-years and 7.0 per 100 person-years, respectively (hazard ratio, 1.40; 95% CI, 1.03 to 1.91; P���=���0.93 for noninferiority); the difference between groups was mainly due to more gastrointestinal bleeding with edoxaban. Rates of death from any cause or stroke were 10.0 per 100 person-years in the edoxaban group and 11.7 per 100 person-years in the vitamin K antagonist group (hazard ratio, 0.85; 95% CI, 0.66 to 1.11). CONCLUSIONS In patients with mainly prevalent atrial fibrillation who underwent successful TAVR, edoxaban was noninferior to vitamin K antagonists as determined by a hazard ratio margin of 38% for a composite primary outcome of adverse clinical events. The incidence of major bleeding was higher with edoxaban than with vitamin K antagonists. (Funded by Daiichi Sankyo; ENVISAGE-TAVI AF ClinicalTrials.gov number, NCT02943785.).

Background In acute myocardial infarction complicated by cardiogenic shock the use of mechanical circulatory support devices remains controversial and data from randomized clinical trials are very limited. Extracorporeal life support (ECLS) - venoarterial extracorporeal membrane oxygenation - provides the strongest hemodynamic support in addition to oxygenation. However, despite increasing use it has not yet been properly investigated in randomized trials. Therefore, a prospective randomized adequately powered clinical trial is warranted. Study Design The ECLS-SHOCK trial is a 420-patient controlled, international, multicenter, randomized, open-label trial. It is designed to compare whether treatment with ECLS in addition to early revascularization with percutaneous coronary intervention or alternatively coronary artery bypass grafting and optimal medical treatment is beneficial in comparison to no-ECLS in patients with severe infarct-related cardiogenic shock. Patients will be randomized in a 1:1 fashion to one of the two treatment arms. The primary efficacy endpoint of ECLS-SHOCK is 30-day mortality. Secondary outcome measures such as hemodynamic, laboratory, and clinical parameters will serve as surrogate endpoints for prognosis. Furthermore, a longer follow-up at 6 and 12 months will be performed including quality of life assessment. Safety endpoints include peripheral ischemic vascular complications, bleeding and stroke. Conclusions The ECLS-SHOCK trial will address essential questions of efficacy and safety of ECLS in addition to early revascularization in acute myocardial infarction complicated by cardiogenic shock.

Left atrial appendage occlusion (LAAO) is recommended for patients with atrial fibrillation at increased stroke risk, where effective long-term oral anticoagulation (OAC) is not feasible. In order to assess long-term safety of LAAO with aspirin monotherapy or no therapy, we aimed to report on patients with the Watchman LAAO device (Boston Scientific) once postimplantation intensified antiplatelet or anticoagulation therapy is discontinued.A total of 1025 patients scheduled for elective LAAO therapy prospectively consented for participation in the EWOLUTION registry; 1005 patients received a successful implant and were followed for 2 years. We identified 766 patients in EWOLUTION on single-antiplatelet therapy (SAPT; n = 639) or no therapy (n = 127) for ≥1 year following LAAO.Three to 6 months after LAAO, 766 patients were switched to SAPT or no therapy and were followed for at least 1 year until the study's conclusion or with events while on SAPT/ no therapy; mean time on SAPT/no therapy was 536.56 ± 177.59 days. Patients experienced 1.4 ischemic strokes per 100 patient years (PY) despite a CHA2DS2-VASC score of 4.3 ± 1.6. Major nonprocedural bleeding rates were low, with 1.3 major bleeds per 100 PY with a mean HAS-BLED score of 2.2 ± 1.2. Furthermore, the ischemic stroke rate in the SAPT/no-therapy subgroup was similar to the whole EWOLUTION collective and high-risk subgroups; the bleeding rate was even lower. When analyzed separately, strokes (2.1/100 PY) and bleedings (1.4/100 PY) of the no-therapy subgroup were similar to patients on SAPT (strokes 0.7/100 PY [P=.70]; bleedings 1.4/100 PY [P=.90]).Outcome data of patients on SAPT/no therapy for ≥1 year following Watchman implantation in the EWOLUTION registry suggest the efficacy and safety of LAAO.

OBJECTIVES: This study sought to report early experience with the new-generation Watchman FLX device (Boston Scientific, Marlborough, Massachusetts).BACKGROUND: The new-generation Watchman FLX features a reduced height, improved anchoring and fabric coverage, and a closed distal end. These design modifications aim to simplify implantation, allow full recapture and repositioning, and reduce peridevice leak and device-related thrombosis.METHODS: A total of 165 patients undergoing left atrial appendage (LAA) occlusion (LAAO) with Watchman FLX were enrolled in a prospective, multicenter registry at 12 centers participating in the European limited market release program.RESULTS: Mean age was 75.4 ± 8.9 years, and CHA2DS2-VASc score 4.4 ± 1.4. A total of 128 patients (77.6%) had a history of major bleeding, including previous intracranial hemorrhage in 55 cases (33.3%). LAA landing zone minimal and maximal mean diameters were 19.1 ± 3.6 mm and 22.3 ± 3.7 mm, and 24.2% of LAA were considered complex by dimensions. Technical success was achieved in all patients. Successful implantation at first attempt was achieved in 129 cases (78.2%), and a second device was required in 6 cases (3.6%). Procedure-related complications occurred in 3 patients (1.8%): 2 access-related (1.2%) and 1 pericardial effusion (0.6%). No peri-procedural strokes, deaths, or device embolizations occurred. Forty-nine patients (29.7%) were discharged with single antiplatelet therapy, 105 (63.6%) on dual antiplatelet, and 11 (6.7%) on anticoagulation. Imaging follow-up displayed just 1 peridevice leak ≥5 mm and 7 cases of device-related thrombosis (4.7%). During a median follow-up of 55 days (interquartile range: 45 to 148 days), there were 6 hemorrhagic complications (4.8%), 1 patient (0.8%) had an ischemic stroke, and 1 (0.8%) died. No late device embolizations occurred.CONCLUSIONS: LAAO with the Watchman FLX is safe and effective in a wide range of LAA morphologies, with a low procedural complication rate, high degree of LAA sealing, and favorable short-term efficacy.

Both balloon-expandable and self-expanding transcatheter aortic valves are used for transcatheter aortic valve implantation (TAVI). We compared procedural and clinical outcome variables of Sapien 3 and Evolut R/Pro in an all-comers collective.In this single-center registry, patients were consecutively treated with the Sapien 3 from November 2014 to March 2017 (n = 129) and from April 2017 to December 2018 mainly (95%) with the Evolut R/Pro (n = 124), due to a switch in the main TAVI supplier driven by hospital management. Data were retrospectively analyzed before and after the switch.One-year follow-up data were available for 122 (94%) of the Sapien and 112 (90%) of the Evolut patients. Baseline characteristics were comparable (EuroSCORE: Sapien 21.8 ± 0.9% vs Evolut 22.5 ± 0.8%; P=.20). Evolut implantation was associated with a higher radiation dose (Sapien 35770 ± 2345 mGy•cm² vs Evolut 85072 ± 8202 mGy•cm²; P.001), more postimplantation balloon dilations (Sapien 17.1% vs Evolut 37.1%; P.001), but similar procedure time (Sapien 75.2 ± 3.8 min vs Evolut 74.6 ± 3 min; P=.30). In-hospital mortality (Sapien 3.1% vs Evolut 4.0%; P=.70), all-cause mortality (Sapien 13.2% vs Evolut 15.3%; P=.70), all-stroke rate (Sapien 1.5% vs Evolut 6.5%; P=.05), and pacemaker implantation rate (Sapien 13.2% vs Evolut 18.5%; P=.30) were similar at 1 year. Permanent pacemaker rate was numerically higher in the first 6 months with Evolut (6 months 26.7% vs6 months 16%; P=.62); furthermore, radiation dose and balloon dilations also suggest a learning curve with Evolut.Switching from Sapien 3 to Evolut R/Pro was not associated with a difference regarding periprocedural or 1-year clinical outcomes.

AIMS: Failure of transcatheter mitral valve repair (fTMVR) therapy has a decisive prognostic influence, and complex retreatment is of higher risk. The aim of this analysis was to evaluate the survival outcome following percutaneous procedures and surgery after unsuccessful TMVR interventions for different aetiologies. METHODS AND RESULTS: Of 824 consecutive patients who had been treated with the MitraClip device at our institution, between September 2009 and May 2019, 63 (7.6%) symptomatic patients with therapy failure and persistent or recurrent mitral regurgitation (MR) underwent reinterventions. An outcome analysis for primary (PMR) and secondary mitral regurgitation (SMR) and subsequent percutaneous versus surgical treatment was carried out. MitraClip reinterventions were performed in 36 patients (57.1%; n=26 SMR, n=10 PMR), while 27 (42.9%; n=13 SMR, n=14 PMR) underwent open heart surgery. Surgical patients with PMR showed lower mortality than patients with SMR (p

Background Very late scaffold thrombosis (VLScT) occurs more frequently after bioresorbable scaffold (Absorb BVS 1.1, Abbott Vascular, Santa Clara, California) implantation than with metallic everolimus-eluting stents. Objectives The purpose of this study was to elucidate mechanisms underlying VLScT as assessed by optical coherence tomography (OCT). Methods The INVEST (Independent OCT Registry on Very Late Bioresorbable Scaffold Thrombosis) registry is an international consortium of investigators who used OCT to examine patients with VLScT. Results Between June 2013 and May 2017, 36 patients with 38 lesions who had VLScT underwent OCT at 19 centers. VLScT occurred at a median of 20 months (interquartile range: 16 to 27 months) after implantation. At the time of VLScT, 83% of patients received aspirin monotherapy and 17% received dual-antiplatelet therapy. The mechanisms underlying VLScT were (in descending order) scaffold discontinuity (42.1%), malapposition (18.4%), neoatherosclerosis (18.4%), underexpansion or scaffold recoil (10.5%), uncovered struts (5.3%), and edge-related disease progression (2.6%). Discontinuity (odds ratio [OR]: 110; 95% confidence interval [CI]: 73.5 to 173; p Conclusions The leading mechanism underlying VLScT was scaffold discontinuity, which suggests an unfavorable resorption-related process, followed by malapposition and neoatherosclerosis. It remains to be determined whether modifications in scaffold design and optimized implantation can mitigate the risk of VLScT.

Background Left atrial appendage (LAA) occlusion with WATCHMAN has emerged as viable alternative to vitamin K antagonists in randomized controlled trials. Objective EWOLUTION was designed to provide data in routine practice from a prospective multicenter registry. Methods A total of 1025 patients scheduled for a WATCHMAN implant were prospectively and sequentially enrolled at 47 centers. Indication for LAA closure was based on European Society of Cardiology guidelines. Follow-up and transesophageal echocardiography (TEE) were performed per local practice. Results The baseline CHA2DS2-VASc score was 4.5 ± 1.6; the mean age was 73.4 ± 9 years; previous transient ischemic attack/ischemic stroke was present in 312 (30.5%), 155 (15.1%) had previous hemorrhagic stroke, and 320 (31.3%) had a history of major bleeding; and 750 (73%) were deemed unsuitable for oral anticoagulation therapy. WATCHMAN implant succeeded in 1005 (98.5%) of patients, without leaks >5 mm in 1002 (99.7%) with at least 1 TEE follow-up in 875 patients (87%). Antiplatelet therapy was used in 784 (83%), while vitamin K antagonists were used in only 75 (8%). At 1 year, mortality was 98 (9.8%), reflecting the advanced age and comorbidities in this population. Device thrombus was observed in 28 patients at routine TEE (3.7%) and was not correlated with the drug regimen (P = .14). Ischemic stroke rate was 1.1% (relative risk 84% vs estimated historical data); the major bleeding rate was 2.6% and was predominantly (2.3%) nonprocedure/device related. Conclusion LAA closure with the WATCHMAN device has a high implant and sealing success. This method of stroke risk reduction appears to be safe and effective with an ischemic stroke rate as low as 1.1%, even though 73% of patients had a contraindication to and were not using oral anticoagulation.

It features the successful use of extracorporeal cardiopulmonary resuscitation in a case of severe left ventricular dysfunction resulting in a favorable outcome.Conclusion. We present the first case of a cardiac arrest due to a refeeding syndrome in anorexia nervosa featuring the successful use of an extracorporeal cardiopulmonary resuscitation approach as a bridge to full recovery.

Aims Evidence regarding post-procedural antithrombotic regimen other than used in randomized trials assessing percutaneous left atrial appendage (LAA) closure is limited. The present work aimed to compare different antithrombotic strategies applied in the real-world EWOLUTION study. Methods and results A total of 998 patients with successful WATCHMAN implantation were available for the present analysis. The composite ischaemic endpoint of stroke, transitory ischaemic attack, systemic embolism and device thrombus, and the bleeding endpoint defined as at least major bleeding were assessed during an initial period (from implant until first medication change) and long-term period (from first change up to 2 years). The antithrombotic medication chosen in the initial phase was dual antiplatelet therapy (DAPT) in 60%, oral anticoagulation (OAC) in 27%, single antiplatelet therapy (SAPT) in 7%, and no medication in 6%. In the second long-term phase, SAPT was used in 65%, DAPT in 23%, no therapy in 8%, and OAC in 4%. No significant differences were found between the groups regarding the ischaemic endpoint both in the initial period (Kaplan–Meier estimated rate 2.9% for DAPT vs. 4.3% for OAC vs. 3.9% for SAPT or no therapy) and in the second period (4.2% for SAPT vs. 1.8% for DAPT vs. 3.5% for no therapy). With respect to bleeding events, the only difference was found in the initial phase with a higher incidence in patients under SAPT or no therapy. Conclusions Tailored antithrombotic treatment using even very reduced strategies such as SAPT or no therapy showed no significant differences regarding ischaemic complications after LAA closure.

Background: Left atrial appendage occlusion with WATCHMAN has emerged as viable alternative to vitamin K antagonists in randomized controlled trials. Evaluating real-life clinical outcomes in atrial fibrillation patients receiving the WATCHMAN left atrial appendage closure technology was designed to collect prospective multicenter outcomes of thromboembolic events, bleeding, and mortality for patients implanted with a WATCHMAN in routine daily practice. Methods: One thousand twenty patients with a WATCHMAN implant procedure were prospectively followed in 47 centers. Left atrial appendage occlusion indication was based on the European Society of Cardiology guidelines. Follow-up and imaging were performed per local practice up to a median follow-up of 2 years. Results: Included population was old (age 73.4±8.9 years), at high risk for stroke (311 prior ischemic stroke/transient ischemic attack and 153 prior hemorrhagic stroke) and bleeding (318 prior major bleeding), with CHA 2 DS 2 -VASc score ≥5 in 49%, hypertension, abnormal renal/liver function, stroke, bleeding history or predisposition, Labile international normalized ratio, elderly, drugs/alcohol concomitantly ≥3 in 40% and oral anticoagulation contraindication in 72%. During follow-up, 161 patients (16.4%) died, 22 strokes were observed (1.3/100 patient-years, 83% reduction versus historic data), and 47 major nonprocedural bleeding events (2.7/100 patient-years, 46% reduction versus historic data). Stroke and bleeding rates were consistently lower than historic data in those with prior ischemic (−76% and −41%) or hemorrhagic (−81% and 67%) stroke and prior bleeding (−85% and −30%). Lowest bleeding rates were seen in patients with early discontinuation of dual antiplatelet therapy. Patients with early discontinuation of antithrombotic therapy showed lower bleeding rates, while they were highest for those with prior bleeding. Device thrombus was observed in 34 patients (4.1%) and was not correlated to drug regimen during follow-up ( P =0.28). Conclusions: During the complete 2-year follow-up of Evaluating Real-Life Clinical Outcomes in Atrial Fibrillation Patients Receiving the WATCHMAN Left Atrial Appendage Closure Technology, patients with a WATCHMAN left atrial appendage occlusion device had consistently low rates of stroke and nonprocedural bleeding, although most were contraindicated to oral anticoagulation and used only single antiplatelet therapy or nothing.

Discontinuity (odds ratio [OR]: 110; 95% confidence interval [CI]: 73.5 to 173; p < 0.001), malapposed struts (OR: 17.0; 95% CI: 14.8 to 19.7; p < 0.001), and uncovered struts (OR: 7.3; 95% CI: 6.2 to 8.8; p < 0.001) were more frequent in the thrombosed than the nonthrombosed scaffold regions. In 2 of 16 patients with scaffold discontinuity, intercurrent OCT before VLScT provided evidence of circularly apposed scaffold struts with minimal tissue coverage. CONCLUSIONS: The leading mechanism underlying VLScT was scaffold discontinuity, which suggests an unfavorable resorption-related process, followed by malapposition and neoatherosclerosis. It remains to be determined whether modifications in scaffold design and optimized implantation can mitigate the risk of VLScT.

Correct sizing of the ostium is a crucial step in left atrial appendage (LAA) occlusion procedures. However, unfavorable anatomy of the ostium often complicates the assessment of the true ostium diameter. We hypothesized that area-derived diameter (ADD) and perimeter-derived diameter (PDD) from three-dimensional transesophageal echocardiogram (3D-TEE) can facilitate this step of the procedure as compared with two-dimensional (2D) measurements.For 55 patients within the ALSTER-LAA registry, retrospective analysis of PDD and ADD was correlated with 2D measurements used during the procedure to ascertain correct size of the Watchman device (Boston Scientific). The observed data were put into relation to the calculated area of the device with 10%-30% compression and the clinical outcome after 30 days. 3D area and perimeter measurements of the LAA ostium matched the calculated range of the different device sizes. Recapture during implantation, gaps5 mm, and device size changes were more often observed when ADDs would also have suggested the use of a larger device.3D ADDs and PDDs are feasible to use in device size decisions. Employing these measurements may allow operators to further reduce intraprocedural recapture maneuvers, peridevice leakage, and device size changes.

Objectives This study questioned whether transaxillary transcatheter aortic valve implantation (TAVI) is feasible as a true percutaneous approach using percutaneous closure devices. Background Transaxillary TAVI is gaining increasing acceptance as an alternative to the transfemoral route; however, the access has always been done via surgical cutdown so far. Methods Between August 2010 and September 2011, a total of 24 high-risk patients with severe aortic valvular stenosis underwent a percutaneous TAVI procedure by direct puncture of the axillary artery without surgical cutdown. For safety reasons and as a target for the puncture, a wire was advanced via the ipsilateral brachial artery. Moreover, a balloon was placed into the subclavian artery via the femoral artery for temporary vessel blockade before percutaneous vessel closure. Vascular closure was performed using either the ProStar XL system (Abbott VascularDevices, Redwood City, California) or 2 ProGlide systems (Abbott VascularDevices). Results The true percutaneous approach was successfully completed in all patients (14 left and 8 right axillary artery cases). Overall mortality at 30 days was 8.3%. Acute vascular closure device success was achieved in 17 patients (71%). Vascular closure device success rate was 100% for the ProGlide device and 37% for the ProStar device, respectively. Seven patients (29%) with failing closure devices were treated by endovascular stent graft implantation without the need for surgical repair. For the last 12 treated patients, direct closure was achieved in 11 patients. Conclusions Direct puncture of the axillary artery for TAVI is feasible and safe if a wire is placed into the subclavian artery via the ipsilateral brachial artery.

Valve-in-valve implantation for degenerated surgical bioprosthetic valves is becoming an increasingly accepted approach in selected high-risk patients. In the past, valve-in-valve implantations have been mainly performed in aortic position and only rarely in mitral position. We describe the case of an 81-year-old female patient with severe mitral regurgitation of a degenerated Carpentier-Edwards biological prosthesis treated by transfemoral and transseptal implantation of a SAPIEN-XT valve.

Nevertheless the promising results of 2nd generation DES, recent findings suggest hypersensitivity reactions caused by the durable polymer coatings leading to chronic inflammation and possibly to late stent strut malapposition. Therefore new DES generations with improved biocompatibility and

A 34-year-old man with a previous history of left pneumectomy with curative intent after diagnosis of intimal sarcoma arising from the left pulmonary artery was referred for increasing dyspnoea, and pain at the right shoulder. The patient was free of tumour relapse at nearly 5 years follow-up. A contrast-enhanced multidetector CT (MDCT) shows a filling defect within the main pulmonary artery (figure 1A). Axial fusion image of integrated [18F]fluorodeoxyglucose positron emission tomography (18FDG PET)/CT confirmed an increased uptake at the same level and additionally at the right scapula, highly suggestive of a metastasis (figure 1B). To relieve the patient's symptoms, and improve his quality of life and his short-term prognosis, a palliative operation was carried out. The main and the right pulmonary arteries were completely resected and successfully reconstructed using a polytetrafluoroethylene …

A 46-year-old patient underwent implantation of a bioresorbable vascular scaffold (BVS) (Absorb 3.5 × 28 mm, Abbott Vascular, Abbott Park, Illinois) in April 2013 for a de-novo stenosis of the right coronary artery ([Figures 1A to 1B][1]). A total of 6 months after implantation, a follow-up
