Clinical Outcomes of Very Elderly Patients With Atrial Fibrillation Receiving On-label Doses of Apixaban: J-ELD AF Registry Subanalysis.

Background Increasing age predisposes patients with atrial fibrillation to both thromboembolic and bleeding events; however, data on outcomes of very elderly patients (aged ≥85 years) receiving appropriate antithrombotic therapy are still limited. Methods and Results The J-ELD AF (Multicenter Prospective Cohort Study to Investigate the Effectiveness and Safety of Apixaban in Japanese Elderly Atrial Fibrillation Patients) Registry is a multicenter prospective observational study of Japanese patients with nonvalvular atrial fibrillation aged ≥75 years taking on-label doses (standard dose of 5 mg BID or reduced dose of 2.5 mg BID) of apixaban.

Aspiration After Sealing the Entrance by Stenting Is a Promising Method to Treat Subintimal Hematoma.

Creation of a distal re-entry site is widely performed to treat subintimal hematoma. However, this method has a risk of further vessel damage. The present aspiration technique after sealing the entry site by stenting is more promising because the hematoma can be reduced without additional vessel damage.

Calcified Nodules in the Superficial Femoral Artery Confirmed by Intravascular Ultrasound, Angioscopy, and Histology.

An 84-year-old man was admitted to the authors' hospital for the treatment of intermittent claudication. Angiography revealed an exophytic calcified nodules in the distal superficial femoral artery. Angioscopy also revealed abundant exophytic atherosclerotic calcification.

The efficacy and safety of left atrial low-voltage area guided ablation for recurrence prevention compared to pulmonary vein isolation alone in patients with persistent atrial fibrillation trial: Design and rationale.

Recurrence rates of atrial fibrillation (AF) after pulmonary vein isolation (PVI) are higher in patients with a left atrial low-voltage area (LVA) than those without. However, the efficacy of LVA guided ablation is still unknown. The purpose of this study-the Efficacy and Safety of Left Atrial Low-voltage Area Guided Ablation for Recurrence Prevention Compared to Pulmonary Vein Isolation Alone in Patients with Persistent Atrial Fibrillation trial (SUPPRESS-AF trial)-is to elucidate whether LVA guided ablation in addition to PVI is superior to PVI alone in patients with persistent AF.

Detrimental effects of elevated transpulmonary gradient on outcomes following restrictive mitral annuloplasty in patients with pre-existing pulmonary hypertension.

Background: This study retrospectively examined the association between elevated trans-pulmonary gradient (TPG), which reflects pre-capillary contribution to pulmonary hypertension (PH), and postoperative pulmonary hemodynamics and outcomes following restrictive mitral annuloplasty (RMA) in patients with pre-existing PH.

Methods: Pre- and postoperative (1 month) cardiac catheterization was performed in 64 patients with severely impaired left ventricular function (i.e.

Characterizing clinical outcomes and factors associated with conduction gaps in VISITAG SURPOINT-guided catheter ablation for atrial fibrillation.

Purpose: Although usefulness of VISITAG SURPOINT (VS) on pulmonary vein isolation (PVI) in catheter ablation of atrial fibrillation has been reported, optimal VS thresholds can depend on the inter-tag distance (ITD) and vice versa. We validated the efficacy of PVI with lower target ITDs and VS values than in previous studies.

Methods: Retrospective review of consecutive patients (N = 100) with paroxysmal (n = 32) or persistent AF (n = 68) undergoing VS-guided ablation between 09/2018 and 08/2019 was conducted.

A practical guide to the lung ultrasound for the assessment of congestive heart failure.

Dyspnea is one of the major symptoms encountered in the emergency department, and lung ultrasound (LUS) is recommended for the rapid diagnosis of the underlying disease. B-lines, the "comet-tail"-like vertical lines moving with respiration, are an ultrasound finding relevant to the pulmonary congestion. They may be observed in the normal lung, but bilateral, ≥ 3 B-lines are considered pathological.

Impact of Chronic Kidney Disease on In-Hospital and 3-Year Clinical Outcomes in Patients With Acute Myocardial Infarction Treated by Contemporary Percutaneous Coronary Intervention and Optimal Medical Therapy - Insights From the J-MINUET Study.

Background: The impact of chronic kidney disease (CKD) on long-term outcomes following acute myocardial infarction (AMI) in the era of modern primary PCI with optimal medical therapy is still in debate.

Methods and results: A total of 3,281 patients with AMI were enrolled in the J-MINUET registry, with primary PCI of 93.1% in STEMI.

Anesthetic management of a patient with severe aortic regurgitation undergoing reoperation for ascending aorta false aneurysm using hypothermia: prevention of ventricular fibrillation by nifekalant.

Background: To prevent cardiac collapse and to protect cerebral function, hypothermic cardiopulmonary bypass is established before resternotomy. However, ventricular fibrillation under hypothermia facilitates left ventricular distension, which causes irreversible myocardial damage when the patient has aortic regurgitation. We report a case of successful management in preventing ventricular fibrillation under hypothermia by using nifekalant.

Long-Term Clinical Impact of Cardiogenic Shock and Heart Failure on Admission for Acute Myocardial Infarction.

Long-term clinical outcomes among patients with cardiogenic shock (CS) and heart failure (HF) who survive the early phase of acute myocardial infarction (AMI) remain uncertain. We investigated 3283 consecutive patients with AMI, selected from a prospective, nation-wide multicenter registry (J-MINUET) database comprising 28 institutions in Japan between July 2012 and March 2014. The 3263 eligible patients were divided into the following three groups: CS-/HF- group (n = 2467, 75.

Validation of the atherothrombotic risk score for secondary prevention in patients with acute myocardial infarction: the J-MINUET study.

Thrombolysis in Myocardial Infarction Risk Score for Secondary Prevention (TRS2°P) is a contemporary risk scoring system for secondary prevention based on nine clinical factors. However, this scoring system has not been validated in other populations. The aim of this study was to validate the TRS2°P in patients with acute myocardial infarction (AMI) treated with primary percutaneous coronary intervention (PCI) in a nationwide registry cohort.

Incidence, determinants and clinical impact of left ventricular function recovery after surgical treatments for ischaemic cardiomyopathy.

Objectives: This retrospective study aimed to clarify the incidence, determinants and clinical impact of left ventricular (LV) function non-recovery after coronary artery bypass grafting (CABG) in patients with ischaemic cardiomyopathy.

Methods: A total of 490 patients with ischaemic cardiomyopathy (LV ejection fraction ≤ 40%) undergoing CABG were analysed. Follow-up echocardiography was performed at 1 month, 1 year, and annually thereafter.

Efficacy of Extensive Ablation for Persistent Atrial Fibrillation With Trigger-Based vs. Substrate-Based Mechanisms - A Prespecified Subanalysis of the EARNEST-PVI Trial.

Background: Extensive ablation in addition to pulmonary vein isolation (PVI) would be effective for modification of non-pulmonary vein (non-PV) substrates, whereas PVI might be sufficient for elimination of PV triggers. This study aimed to test the hypothesis that in patients with reproducible atrial fibrillation (AF) triggered by premature atrial contractions originating only from PVs, PVI alone can be sufficient to maintain sinus rhythm.

Methods and results: This study is a prespecified subanalysis of the EARNEST-PVI randomized controlled trial.

Prognostic significance of the HFA-PEFF score in patients with heart failure with preserved ejection fraction.

Aims: The HFA-PEFF score is a part of the stepwise diagnostic algorithm of heart failure with preserved ejection fraction (HFpEF). We aimed to evaluate the prognostic significance of the HFA-PEFF score on the clinical outcomes in patients with HFpEF.

Methods And Results: The Prospective mUlticenteR obServational stUdy of patIenTs with Heart Failure with preserved Ejection Fraction (PURSUIT-HFpEF) study is a prospective, multicentre, observational study in which collaborating hospitals in Osaka record clinical, echocardiographic, and outcome data of patients with acute decompensated heart failure with preserved left ventricular ejection fraction (≥50%) [UMIN-CTR ID: UMIN000021831].

Comparison of Long-Term Outcomes Between Combination Antiplatelet and Anticoagulant Therapy and Anticoagulant Monotherapy in Patients With Atrial Fibrillation and Left Atrial Thrombi.

Anticoagulation for patients with atrial fibrillation (AF) complicated by left atrial thrombi (LAT) is a frequent cause of bleeding complications, but risk factors remain unknown. Of 3,139 AF patients who underwent transesophageal echocardiography, 82 with LAT under anticoagulation were included in this study. Patients treated with combination antiplatelet and anticoagulant therapy (n=31) were compared with those receiving anticoagulant monotherapy (n=51) to investigate the effects of antiplatelet agents during anticoagulation on bleeding complications.
