Prothrombin time (PT) has been widely used for measuring anticoagulation intensity under rivaroxaban therapy, but precise information has not been well established yet. Consecutive 96 non-valvular atrial fibrillation (NVAF) under rivaroxaban between Jan/June, 2015 were recruited. Serum concentration (SC) and PT with 5 representative reagents available in Japan (Neoplastin Plus®, Thromborel S®, Thrombocheck PT®, Thrombocheck PT Plus®, and Recombiplastin®) at 2-4 hours after (peak) and before intake of rivaroxaban (trough) were measured at outpatient clinic in the cardiovascular institute (CVI ARO study 1)...

BACKGROUND: In atrial fibrillation (AF) patients with coronary artery disease (CAD), anticoagulants are commonly used in combination with antiplatelet drugs. However, dual therapy can increase the risk of bleeding, and the potential therapeutic benefits must be weighed against this. Therefore, it is recommended that dual therapy is only used for a limited time, and that monotherapy with anticoagulants should start from 1 year after percutaneous coronary intervention (PCI). However, there is a lack of evidence on the use of monotherapy, in particular with direct oral anticoagulants, in this group of patients...

A patient presented with a decompensated cardiomyopathy requiring invasive hemodynamic support with an Impella® heart pump. Extracorporeal life support (ECLS) became necessary during the further course and the patient was bridged to left ventricular assist device (LVAD) implantation. Postoperatively, the patient did not improve as expected due to new aortic regurgitation (AR) that was most likely caused by the previously placed Impella. A SAPIEN 3 transcatheter aortic valve was implanted as a bail-out strategy; an additional valve-in-valve rescue was required due to paravalvular regurgitation...

BACKGROUND: Myxomatous mitral valve disease (MMVD) is one of the most prevalent valvular heart diseases, while back pain, neck pain and upper-extremity numbness are some of the most common complaints in outpatient settings. Decreased thoracic kyphosis (straight back) is a known cause of hastening back or neck problems, radiculopathy, or even myelopathy. The study aim was to examine the relationship between MMVD, straight back, and the need for cervical fusion. METHODS: In this single-center retrospective study, patients who underwent mitral valve repair or replacement due to MMVD (cases) based on age, gender and body mass index (BMI), were matched with patients who underwent coronary artery bypass grafting (CABG) surgery and had no history of mitral valve disease (controls)...

OBJECTIVE: Acute heart failure (AHF) is one of the most commonly seen clinical cases, with a high rate of re-hospitalization and mortality. AHF can be divided into two categories based on the systolic function of the left ventricle, which are heart failure with reduced ejection fraction (HFREF) and heart failure with preserved ejection fraction (HFPEF). Pathogenesis and treatment of the two are quite different. In this article we attempted to explore the value of combined use of clinical and laboratory indicators in the differential diagnosis of AHFREF and AHFPEF...

There is a general lack of studies evaluating medication adherence with self-report scales for elderly patients in treatment with direct oral anticoagulants (DOACs). The aim of the study was to assess the degree of adherence to DOAC therapy in a population of elderly outpatients aged 65 years or older affected by non-valvular atrial fibrillation (NVAF), using the 4-item Morisky Medication Adherence Scale, and to identify potential factors, including the geriatric multidimensional evaluation, which can affect adherence in the study population...

Valve stiffening is a hallmark of aortic valve stenosis caused by excess extracellular matrix accumulation by myofibroblasts. We aimed to elucidate whether matrix stiffness regulates endothelial-to-mesenchymal transition (EndMT) of adult valvular endothelial cells (VECs) to myofibroblasts as a mechanism to further promote valve fibrosis. In addition, we specifically examined the role of the Wnt/β-catenin signaling pathway in the development of myofibroblasts during EndMT, as Wnt/β-catenin signaling has been implicated in EndMT during heart development, is reactivated in valve disease, and is required for mechanically-regulated myofibrogenesis of valve interstitial cells...

BACKGROUND: Reduced leaflet motion (RLM) of transcatheter aortic valves (TAV) is observed in up to 4% of cases with similar frequency in surgical valves, with an overall incidence that differs based on prosthesis type and size. This phenomenon likely represents subclinical leaflet thrombosis. Herein we sought to analyze the existing reported literature to assess whether or not RLM is associated with subsequent valve degeneration or cerebrovascular events. METHODS AND RESULTS: We searched PubMed, and EMBASE (2008-2017) to identify relevant studies...

Although thought to be a rare event, permanent pacemakers and implantable cardioverter-defibrillators with right ventricular intracardiac leads have the potential to induce tricuspid valve dysfunction. Adverse lead-valve interactions can take place through a variety of mechanisms including damage at the time of implantation, leaflet pinning, or long-term fibrosis encapsulating the leaflet tissue. Clinical manifestations can display a wide range of severity, as well as a highly variable time span between implantation and hemodynamic deterioration...

We report a very rare case of mitral valve dissection and aortic-left ventricular tunnel caused by possible autoimmune vasculitis. We suspected Behcet's disease in this patient. There was no obvious clinical evidence of infective endocarditis. Echocardiography is the diagnostic tool of choice to recognize valvular dysfunction, related pathology, and possible complications. The patient may require immunosuppressive therapy due to the high likelihood of recurrence in the perioperation period.

Chronic inflammation and resulting tissue damage underlie the vast majority of acquired cardiovascular disease (CVD), a general term encompassing a widely diverse array of conditions. Both innate and adaptive immune mechanisms contribute to chronic inflammation in CVD. Although maladies, such as atherosclerosis and cardiac fibrosis, are commonly conceptualized as disorders of inflammation, the cellular and molecular mechanisms that promote inflammation during the natural history of these diseases in human patients are not fully defined...

Generally, anticoagulation therapy is not essential for patients who maintain sinus rhythm after mitral valvuloplasty. A 66-year-old woman who had undergone mitral valvuloplasty and maze procedure for treatment of mitral valve regurgitation and atrial fibrillation 4 years ago was diagnosed as having left atrial thrombosis despite maintenance of sinus rhythm on electrocardiography. Echocardiography showed narrow mitral valvular area(1.5 cm2), loss of A wave and a huge left atrium. Repeat surgery was performed to replace the mitral valve and to remove the thrombus...

BACKGROUND: Atrial fibrillation/flutter (AF) produces significant morbidity in women and is typically attributed to cardiac remodeling from multiple causes, particularly hypertension. Hypertensive pregnancy disorders (HPDs) are associated with future hypertension and adverse cardiac remodeling. We evaluated whether women with AF were more likely to have experienced a HPD compared with those without. METHODS AND RESULTS: A nested case-control study was conducted within a cohort of 7566 women who had a live or stillbirth delivery in Olmsted County, Minnesota between 1976 and 1982...

BACKGROUND: Left atrial appendage closure (LAAC) is an efficient alternative of oral anticoagulation to prevent stroke in patients with non-valvular atrial fibrillation (NVAF). Due to complexities of LAA anatomy, a complete closure may not always be obtained with a single device. The aim of this study was to evaluate the feasibility and safety of the staged 'kissing-Watchman' technology to occlude the LAA with complex anatomy. METHODS: In our center, among 300 cases underwent LAAC with Watchman device from February 2012 to December 2016, 7 complex LAAs were implanted double devices using the staged 'kissing-Watchman' technology...

BACKGROUND: Physical examination of jugular venous pressure is used to estimate right atrial (RA) pressure and infer left-sided filling pressure to assist volume management. Previous studies in advanced heart failure patients showed about 75% concordance between RA and pulmonary capillary wedge (PCW) pressures. We sought to determine the relationship between mean RA and mean PCW pressure and assess the clinical significance in a broad population of patients undergoing invasive right heart catheterization (RHC)...

Atrial fibrillation (AF) is associated with high risk of systemic thromboembolism leading to significant morbidity and mortality. Warfarin, previously the mainstay for stroke prevention in AF, requires close monitoring because of multiple food and drug interactions. In recent years, food and drug administration has approved several direct oral anticoagulants (DOACs) for use in patients with nonvalvular AF. These agents have not been studied in patients with valvular AF who are at an even higher risk of systemic thromboembolism...

Background: Although not designated as guideline-recommended first-line anticoagulation therapy, patients are receiving rivaroxaban for the treatment and secondary prevention of cancer-associated venous thrombosis (CAT). We sought to estimate the cumulative incidence of recurrent venous thromboembolism (VTE), major bleeding, and mortality/hospice care in patients with CAT treated with outpatient rivaroxaban in routine practice. Methods: Using US MarketScan claims data from January 2012 through June 2015, we identified adults with active cancer (using SEER program coding) who had ≥1 primary hospitalization or emergency department discharge diagnosis code for VTE (index event) and received rivaroxaban as their first outpatient anticoagulant within 30 days of the index VTE...
