Impact of conscious sedation and general anesthesia on periprocedural outcomes in Watchman left atrial appendage closure

Background: Transcatheter left atrial appendage closure (LAAC) is performed either in conscious sedation (CS) or general anesthesia (GA), and limited data exist regarding clinical outcomes for the two approaches. The aim of the study was to analyze the effect of CS versus GA on acute outcomes in a large patient cohort undergoing LAAC with a Watchman occluder.Methods: A cohort of 521 consecutive patients underwent LAAC with Watchman occluders at two centers (REGIOMED hospitals, Germany) between 2012 and 2018. One site performed 303 consecutive LAAC procedures in GA, and the other site performed 218 consecutive procedures in CS. The safety endpoint was a composite of major periprocedural complications and postoperative pneumonia. The efficacy endpoint was defined as device success.Results: After a 1:1 propensity score matching, 196 (CS) vs. 115 (GA) patients could be compared. In 5 (2.6%) cases CS was converted to GA. The primary safety endpoint (3.5% [CS] vs. 7.0% [GA], p = 0.18) and its components (major periprocedural complications: 2.5% vs. 3.5%, p = 0.73; postoperative pneumonia: 2.6% vs. 4.3%, p = 0.51) did not differ between the groups. Also, device success was comparable (96.9% vs. 93.9%, p = 0.24).Conclusions: In patients undergoing LAAC with the Watchman device, conscious sedation and general anesthesia showed comparable device success rates and safety outcomes. The type of anesthesia for LAAC may therefore be tailored to patient comorbidities, operator experience, and hospital logistics

The Changing Landscape for Stroke\ua0Prevention in AF: Findings From the GLORIA-AF Registry Phase 2

Background GLORIA-AF (Global Registry on Long-Term Oral Antithrombotic Treatment in Patients with Atrial Fibrillation) is a prospective, global registry program describing antithrombotic treatment patterns in patients with newly diagnosed nonvalvular atrial fibrillation at risk of stroke. Phase 2 began when dabigatran, the first non\u2013vitamin K antagonist oral anticoagulant (NOAC), became available. Objectives This study sought to describe phase 2 baseline data and compare these with the pre-NOAC era collected during phase 1. Methods During phase 2, 15,641 consenting patients were enrolled (November 2011 to December 2014); 15,092 were eligible. This pre-specified cross-sectional analysis describes eligible patients\u2019 baseline characteristics. Atrial fibrillation disease characteristics, medical outcomes, and concomitant diseases and medications were collected. Data were analyzed using descriptive statistics. Results Of the total patients, 45.5% were female; median age was 71 (interquartile range: 64, 78) years. Patients were from Europe (47.1%), North America (22.5%), Asia (20.3%), Latin America (6.0%), and the Middle East/Africa (4.0%). Most had high stroke risk (CHA2DS2-VASc [Congestive heart failure, Hypertension, Age  6575 years, Diabetes mellitus, previous Stroke, Vascular disease, Age 65 to 74 years, Sex category] score  652; 86.1%); 13.9% had moderate risk (CHA2DS2-VASc = 1). Overall, 79.9% received oral anticoagulants, of whom 47.6% received NOAC and 32.3% vitamin K antagonists (VKA); 12.1% received antiplatelet agents; 7.8% received no antithrombotic treatment. For comparison, the proportion of phase 1 patients (of N = 1,063 all eligible) prescribed VKA was 32.8%, acetylsalicylic acid 41.7%, and no therapy 20.2%. In Europe in phase 2, treatment with NOAC was more common than VKA (52.3% and 37.8%, respectively); 6.0% of patients received antiplatelet treatment; and 3.8% received no antithrombotic treatment. In North America, 52.1%, 26.2%, and 14.0% of patients received NOAC, VKA, and antiplatelet drugs, respectively; 7.5% received no antithrombotic treatment. NOAC use was less common in Asia (27.7%), where 27.5% of patients received VKA, 25.0% antiplatelet drugs, and 19.8% no antithrombotic treatment. Conclusions The baseline data from GLORIA-AF phase 2 demonstrate that in newly diagnosed nonvalvular atrial fibrillation patients, NOAC have been highly adopted into practice, becoming more frequently prescribed than VKA in Europe and North America. Worldwide, however, a large proportion of patients remain undertreated, particularly in Asia and North America.

Rare finding using transthoracic echocardiography leading to a prognostically important diagnosis

Background: We report about a very interesting and none common finding observed using transthoracic echocardiography (TTE). A patient with new documented symptomatic atrial fibrillation (AF) who was admitted to our clinic for further clarification and stabilization received a routine TTE and transesophageal echocardiography (TEE) as a step before electrical cardioversion. The TTE revealed an extracardiac structure compressing the left atrium (LA), which was not observed on the TEE. For further clarification, the patient received a computer tomography of the chest which revealed an esophageal carcinoma. No specific symptoms of the disease were reported from the patient before this admission. Conclusion: TTE is the most commonly performed cardiac investigation. It provides generally very valuable information about cardiac structure and function. Our case shows the role of this method in identifying extra cardiac formation leading to important diagnosis

Long-term clinical outcomes of Amplatzer cardiac plug versus Amulet occluders for left atrial appendage closure.

OBJECTIVES To compare long-term clinical outcomes after left atrial appendage closure with the Amplatzer Cardiac Plug (ACP) and Amulet. BACKGROUND The Amulet was designed to improve clinical outcomes of first-generation ACP. METHODS Three Amplatzer registries (Bern, Coburg, Zurich), with enrollment of patients from 2009 to 2018, were retrospectively analyzed. The primary safety endpoint was a composite of major peri-procedural complications and major bleedings, the primary efficacy endpoint included stroke, systemic embolism, and cardiovascular/unexplained death. The net clinical benefit was a combination of all above-mentioned hazards. RESULTS A total of consecutive 563 patients (344 ACP vs. 219 Amulet) with a mean follow-up of 2.9 ± 1.6 and 1.9 ± 0.9 years were included. Mean age (74.4 ± 9.9 [ACP] vs. 74.4 ± 9.1 [Amulet] years), stroke (CHA2 DS2 -VASc score 4.4 ± 1.6 vs. 4.6 ± 1.7), and bleeding risk (HAS-BLED score 3.2 ± 1.1 vs. 3.2 ± 0.9) were comparable. The primary endpoints of efficacy (72/998, 7.2% [ACP] vs. 43/417, 10.3% [Amulet]; hazard ratio [HR], 0.67; 95% confidence interval [CI], 0.44-1.02, p = .062), safety (40/998, 4.0% vs. 18/417, 4.3%; HR, 1.15; 95% CI, 0.53-2.51, p = .72), and the net clinical benefit (101/998, 10.1% vs. 55/417, 13.4%; HR, 0.73; 95% CI, 0.49-1.07, p = .11) were similar. CONCLUSION In the long term, left atrial appendage closure with first and second-generation Amplatzer devices provided similar efficacy, safety, and net clinical benefit. Clinical outcomes may be rather determined by implantation technique and hemodynamics, but not by the design modifications of the Amulet

Amplatzer left atrial appendage closure: access via transseptal puncture versus patent foramen ovale or atrial septal defect.

AIMS To compare periprocedural and late clinical outcomes of left atrial appendage closure (LAAC) with Amplatzer devices by access through transseptal puncture (TSP) versus a patent foramen ovale (PFO) or an atrial septal defect (ASD). METHODS AND RESULTS Between 2009 and 2018, 578 consecutive patients underwent LAAC via TSP or PFO/ASD access in three centers. After a 1:3 propensity score matching, 246 (TSP) vs 246 (PFO/ASD) patients were compared by use of the primary efficacy endpoint of all-cause stroke, systemic embolism and cardiovascular/unexplained death and the primary safety endpoint of major peri-procedural complications and major bleedings at follow-up. Mean age was 75.2±8.7 (TSP) vs 74.4±10.9 (PFO/ASD) years, CHA2DS2-VASc score 4.5±1.6 vs 4.3±1.4, and HAS-BLED score 3.3±1.0 vs 3.3±0.9. Device success (97.6% vs 97.8%, p=0.90) was similar. After 2.5±1.4 vs 2.6±1.6 years, clinical efficacy (46/603, 7.6% [TSP] vs 21/233, 9.0% [PFO/ASD], 10.3, hazard ratio (HR), 1.2; 95% confidence interval (CI), 0.69-0.85, p=0.54) and safety (24/603, 4.0% vs 11/233, 4.7%; HR, 1.4; 95% CI, 0.52-3.6, p=0.49) did not differ. CONCLUSIONS Use of a PFO/ASD access for LAAC with Amplatzer devices offers similar periprocedural and late clinical outcomes as TSP. Simultaneous PFO/ASD closure for an additional protective benefit does not increase risk

Effects of remote haemodynamic-guided heart failure management in patients with different subtypes of pulmonary hypertension: insights from the MEMS-HF study

Aim: The CardioMEMS European Monitoring Study for Heart Failure (MEMS-HF) investigated safety and efficacy of pulmonary artery pressure (PAP)-guided remote patient management (RPM) in New York Heart Association (NYHA) class III outpatients with at least one heart failure hospitalization (HFH) during the previous 12 months. This pre-specified subgroup analysis investigated whether RPM effects depended on presence and subtype of pulmonary hypertension (PH). Methods and results: In 106/234 MEMS-HF participants, Swan–Ganz catheter tracings obtained during sensor implant were available for off-line manual analysis jointly performed by two experts. Patients were classified into subgroups according to current PH definitions. Isolated post-capillary PH (IpcPH) and combined post- and pre-capillary PH (CpcPH) were present in 38 and 36 patients, respectively, whereas 31 patients had no PH. Clinical characteristics were comparable between subgroups, but among patients with PH pulmonary vascular resistance was higher (p = 0.029) and pulmonary artery compliance lower (p = 0.003) in patients with CpcPH. During 12 months of PAP-guided RPM, all PAPs declined in IpcPH and CpcPH subgroups (all p < 0.05), whereas only mean and diastolic PAP decreased in patients without PH (both p < 0.05). Improvements in post- versus pre-implant HFH rates were similar in CpcPH (0.639 events/patient-year; hazard ratio [HR] 0.37) and IpcPH (0.72 events/patient-year; HR 0.45) patients. Participants without PH benefited most (0.26 events/patient-year; HR 0.17, p = 0.04 vs. IpcPH/CpcPH patients). Quality of life and NYHA class improved significantly in all subgroups. Conclusions: Outpatients with NYHA class III symptoms with at least one HFH during 1 year pre-implant benefitted significantly from PAP-guided RPM during post-implant follow-up irrespective of presence or subtype of PH at baseline
