Atrial fibrillation is commonly coexistent with heart failure, and the management of the heart failure patient would be incomplete without an appreciation for atrial fibrillation management. There are many complications associated with oral anticoagulation in the prevention of stroke related to atrial fibrillation. In recent years, the advent of several percutaneous left atrial appendage (LAA) occlusion/closure strategies has sought to provide an alternative treatment modality. Here, we systematically review the published literature to investigate the efficacy and safety of percutaneous LAA occlusion/closure devices...

Catheter ablation is an effective treatment in patients with symptomatic atrial fibrillation. Complications are infrequent and usually resolve with minimal or no intervention, but active bleeding due to arterial injury during the vascular access can sometimes represent a life-threatening complication. Contrast-enhanced computed tomography is the standard technique to detect active bleeding, but it may not be immediately available. We report a case of iatrogenic hemorrhage after catheter ablation, in which contrast-enhanced ultrasonography played a decisive role in the recognition of active arterial bleeding due to injury to the right common femoral artery...

Sympathetic activation causes clinically important arrhythmias including atrial fibrillation (AF) and ventricular tachyarrhythmia. Although the usefulness of β-adrenergic receptor blockade therapy is widely accepted, its multiple critical side effects often prevent its initiation or continuation. The aim of this study is to determine the advantages of vidarabine, an adenylyl cyclase (AC)-targeted anti-sympathetic agent, as an alternative treatment for arrhythmia. We found that vidarabine, which we identified as a cardiac AC inhibitor, consistently shortens AF duration and reduces the incidence of sympathetic activation-induced ventricular arrhythmias...

BACKGROUND AND STUDY OBJECTIVE: Different studies have shown a good long-term survival with improvement of symptoms and hemodynamics after percutaneous septal ablation (PTSMA), similar to myectomy considered to be the therapeutic "gold standard" for symptomatic hypertrophic obstructive cardiomyopathy (HOCM). Furthermore, desobliteration of left ventricular (LV) outflow may modify features of the disease considered to be risk-relevant, such as magnitude of LV hypertrophy, outflow gradient, and left atrial (LA) size...

Atrial fibrillation (AF) is frequent in patients with rheumatic mitral stenosis (MS). Pressure overload leads to marked structural and electrical remodelling of left atrium. The frequency of persistent AF increases with age and paroxysmal, asymptomatic, AF seems even more frequent. The occurrence of AF worsens the haemodynamic tolerance of MS and markedly increases the risk of thromboembolic events. AF has a negative impact on the natural history of MS and on its outcome after commissurotomy. The respective indications of rhythm and rate control should be adapted to patient characteristics, particularly the consequences of MS, and take into account the high risk of recurrence of AF...

BACKGROUND: Non-vitamin K antagonist oral anticoagulants (NOACs) are indicated for stroke prevention in atrial fibrillation (AF) but require lower doses in certain patients. We sought to describe the frequency, appropriateness (according to Food and Drug Administration labeling), and outcomes of patients prescribed reduced doses of NOACs in community practice. METHODS AND RESULTS: We analyzed data from the ORBIT-AF II (The Outcomes Registry for Better Informed Treatment of Atrial Fibrillation II) registry, a prospective, national, observational registry of AF patients...

A left atrial appendage occluder device (Watchman) and leadless pacemaker (Micra) was implanted from a single right femoral vein access in a 73-year-old female patient with persistent atrial fibrillation and symptomatic tachy-brady syndrome and unable to take oral anticoagulants. Standard methods of implantation were followed for both procedures. The Watchman device was implanted first followed by dilatation of the same venous access site in order to implant Micra transcatheter pacing system. The patient tolerated the procedures well and there were no complications...

BACKGROUND: Increasing evidence exists regarding calcium detected in aortic cusps and/or mitral annulus (AOC_MAC) at transthoracic echocardiogram as a predictor of cardiovascular (CV) events and mortality. PURPOSE: To verify whether AOC_MAC has a prognostic role in the setting of primary prevention independently of the presence of atrial fibrillation (AF). METHODS: All subjects consecutively referred from January 2011 to October 2014 to the Cardiovascular Centre for CV risk assessment in primary prevention were selected...

Heart failure is a complex disease, which is presented differently by men and women. Several studies have shown that reproductive factors, such as age at natural menopause, parity and polycystic ovarian syndrome (PCOS), may play a role in the development of heart failure. Shared genetics may provide clues to underlying mechanisms; however, this has never been examined. Therefore, the aim of the current study was to explore whether any reproductive factor is potentially related to heart failure in women, based on genetic similarities...

BACKGROUND: An effective catheter ablation strategy, beyond pulmonary vein isolation (PVI), for persistent atrial fibrillation (AF) is necessary. Pulmonary vein (PV)-reconduction also causes recurrent atrial tachyarrhythmias. The effect of the PVI and additional effect of a superior vena cava (SVC) isolation (SVCI) was strictly evaluated. METHODS: Seventy consecutive patients with persistent AF who underwent a strict sequential ablation strategy targeting the PVs and SVC were included in this study...

BACKGROUND: The predictive role of E/e' on ischemic stroke (IS) and atrial fibrillation (AF) in Japanese patients without AF are unclear. METHODS AND RESULTS: Shinken database includes all the new patients visiting the Cardiovascular Institute Hospital in Tokyo, Japan. E/e' has been routinely measured since 2007. Patients without AF for whom E/e' was measured at the initial visit between 2007 and 2014 (n=11 477, mean age 57.2 years old, men 59.5%) were divided into E/e' tertiles (<8...

BACKGROUND: Interpreting evaluations of complex interventions can be difficult without sufficient description of key intervention content. We aimed to develop an implementation package for primary care which could be delivered using typically available resources and could be adapted to target determinants of behaviour for each of four quality indicators: diabetes control, blood pressure control, anticoagulation for atrial fibrillation and risky prescribing. We describe the development and prospective verification of behaviour change techniques (BCTs) embedded within the adaptable implementation packages...

OBJECTIVES: Conventional cardiopulmonary bypass is the most commonly used means of artificial circulation in cardiac surgery. However, it suffers from the effects of haemodilution and activation of inflammatory/coagulation cascades. Prime displacement (PD) can offset haemodilution and Mini-Extracorporeal Technology (MIECT) can offset both. So far, no study has compared all of these modalities together; hence, we compared the outcomes of these 3 modalities at our institution. METHODS: This was a retrospective analysis of our cardiac surgical database...

Inappropriate tests are responsible for longer waiting lists, higher economical costs for the National Health System and major clinical risks due to radiation exposure from prescription abuse of diagnostic testing. Clinical inappropriateness frequently derives from poor knowledge of guidelines, "defensive medicine" approach and/or repeat requests of patients and family members. About one third of non-invasive imaging tests are considered inappropriate.In order to define the most appropriate instruments for the follow-up of the most common cardiovascular diseases with the highest risk of inappropriateness, all the cardiologists of the Veneto Region (Italy), along with the local chapters of the main national cardiology societies and general practitioners have been involved by the Regional Section of the Italian Association of Hospital Cardiologists (ANMCO) in several scientific meetings on the following topics: hypertension, chronic ischemic heart disease, valvular heart disease, heart failure, and atrial fibrillation...

Understanding arrhythmias and their treatment is not always easy. The current straightforward approach with catheter ablation and device therapy is an amazing achievement, but does not make management of underlying or other cardiac disease and pharmacological therapy unnecessary. The goal of this paper is to describe how much of the knowledge of the 1980s and early 1990s can and should still be applied in the modern treatment of patients with arrhythmias. After an introduction, this review will focus on paroxysmal atrial fibrillation and a prototype of 'idiopathic' ventricular arrhythmias, two diseases with a striking similarity, and will discuss the arrhythmogenesis...
