BACKGROUND: Prosthetic valve endocarditis (PVE) due to methicillin resistant Staphylococcus aureus (MRSA) is a rare disease with significant mortality and morbidity. With the emerging resistance and adverse effect profile of vancomycin which is the standard treatment, there is a compelling necessity of an effective alternative for vancomycin. Linezolid is proved as such an agent for infections caused by MRSA in other sites. However to-date the evidence for successful use of linezolid for MRSA prosthetic valve endocarditis is limited only for few case studies...

BACKGROUND: Early risk stratification after primary percutaneous coronary intervention (PPCI) for ST-segment-elevation myocardial infarction is currently challenging. Identification of a low-risk group may improve triage of patients to alternative clinical pathways and support early hospital discharge. Our aim was to assess whether the index of microcirculatory resistance (IMR) at the time of PPCI can identify patients at low risk of early major cardiac complications and to compare its performance against guideline-recommended risk scores...

BACKGROUND: Although large randomized clinical trials have found that primary prevention use of an implantable cardioverter-defibrillator (ICD) improves survival in patients with cardiomyopathy and heart failure symptoms, patients who receive ICDs in practice are often older and have more comorbidities than patients who were enrolled in the clinical trials. In addition, there is a debate among clinicians on the usefulness of electrophysiological study for risk stratification of asymptomatic patients with Brugada syndrome...

Aims: Cardiac magnetic resonance (CMR) is recommended as a second-line method to diagnose ventricular arrhythmia (VA) substrate. We assessed the diagnostic yield of CMR including high-resolution late gadolinium-enhanced (LGE) imaging. Methods and results: Consecutive patients with sustained ventricular tachycardia (VT), non-sustained VT (NSVT), or ventricular fibrillation/aborted sudden death (VF/SCD) underwent a non-CMR diagnostic workup according to current guidelines, and CMR including LGE imaging with both a conventional breath-held and a free-breathing method enabling higher spatial resolution (HR-LGE)...

BACKGROUND: Observational studies suggest that in patients with a CTO successful recanalization is associated with better clinical outcome. This could be related to a reduction in the occurrence of arrhythmias, which may result from modifications of the hibernating myocardium in a CTO region. METHODS AND RESULTS: We aimed to evaluate the effect of CTO PCI on electrophysiological parameters, and conducted a systematic review and meta-analysis according to the PRISMA guidelines...

Cardiac resynchronization therapy (CRT) is an established therapy for heart failure and can be delivered through a CRT pacemaker (CRT-P) or a CRT defibrillator (CRT-D). CRT-P devices are smaller and less expensive, have better battery longevity, and have been subject to fewer recalls and advisories but cannot deliver high-energy shocks to terminate potentially lethal ventricular arrhythmias. As published guidelines do not distinguish between CRT-P and CRT-D indications, we examined the practice of prescribing these devices in older women and men with heart failure...

Fabry disease (FD) is an X-linked lysosomal storage disorder caused by deficiency of α-galactosidase A enzyme. Cardiovascular (CV) disease is a common cause of mortality in FD, in particular as a result of heart failure and arrhythmia, with a significant proportion of events categorized as sudden. There are no clear models for risk prediction in FD. This systematic review aims to identify the risk factors for ventricular arrhythmia (VA) and sudden cardiac deaths (SCD) in FD. A systematic search was performed following PRISMA guidelines of EMBASE, Medline, PubMed, Web of Science, and Cochrane from inception to August 2016, focusing on identification of risk factors for the development of VA or SCD...

Takotsubo syndrome (TTS) was first described in 1991 as a rare, spontaneous and completely reversible left ventricular regional systolic dysfunction. Today the incidence of TTS is estimated at 2% in patients with an initial diagnosis of acute coronary syndrome (ACS). Notably, the incidence can be as high as 5.9 to 7.5% in female patients. TTS occurs predominantly in postmenopausal women, but both sexes may be affected, at any age. Acute chest pain or dyspnoea is a characteristic symptom of TTS, but initial presentation can also include more severe disease manifestation such as acute heart failure with pulmonary oedema or haemodynamic instability, especially in an in-hospital setting...

Aims: In this study, we aimed to clinically and genetically characterize LVNC patients and investigate the prevalence of variants in known and novel LVNC disease genes. Introduction: Left ventricular non-compaction cardiomyopathy (LVNC) is an increasingly recognized cause of heart failure, arrhythmia, thromboembolism, and sudden cardiac death. We sought here to dissect its genetic causes, phenotypic presentation and outcome. Methods and results: In our registry with follow-up of in the median 61 months, we analysed 95 LVNC patients (68 unrelated index patients and 27 affected relatives; definite familial LVNC = 23...

INTRODUCTION    The current guidelines of the European Society of Cardiology outlined electrocardiographic (ECG) differentiation of site of origin (SOO) in patients with idiopathic ventricular arrhythmias (IVA).  OBJECTIVES    The aim of this study was to compare three ECG algorithms for differentiating SOO and to determine their diagnostic value for the management of outflow tract IVA. PATIENTS AND METHODS    Patients with IVA with inferior axis who underwent successful radiofrequency catheter ablation (RFCA) using the 3D-electroanatomical system were analyzed...

BACKGROUND: A proportion of patients who receive cardiac resynchronization therapy with defibrillator (CRT-D) live to receive a second generator. Controversy exists on whether an implantable cardioverter-defibrillator (ICD) should be offered to patients who have normalized or near-normalized left ventricular ejection fraction (LVEF) at the time of generator replacement (GR). OBJECTIVE: The purpose of this study was to evaluate incidence of appropriate ICD therapy after CRT-D GR...

The current regulatory guidelines recommend the use of QT interval to assess the risk of arrhythmogenic potential of new chemical entities. Recently, the electromechanical window (EMW), the difference in duration between electrical and mechanical systole, has been proposed as markers for drug-induced torsades de pointes (TdP); however, data of EMW in short QT model are not available. This study aimed to characterize the EMW as a marker for drug-induced ventricular arrhythmias in anesthetized rabbit model of long QT syndrome type 2 (LQT2) and short QT syndrome (SQTS) infused with reference compounds known to lengthen or shorten QT intervals...

BACKGROUND: Published studies state that adherence to regular laboratory assessments for anti-arrhythmic drugs is as low as 20%. Monitoring adherence is important as other studies have shown that up to 93% of patients on amiodarone experience an adverse drug event leading to a potentially lethal event. OBJECTIVE: To determine whether patients prescribed amiodarone or dofetilide are being monitored according to package labeling and guideline recommendations for adverse events...

BACKGROUND: The main causes of mortality in patients with chronic heart failure include sudden cardiac death (SCD) and progressive heart failure. Autonomic dysfunction plays a detrimental role in the progression of chronic heart failure. Left cardiac sympathetic denervation (LCSD) is an inexpensive and safe procedure which modifies autonomic innervation of the heart and is associated with a significant antifibrillatory effect. Whether LCSD reduces the risk of SCD, delays progression of heart failure and improves quality of life in patients with heart failure with reduced ejection fraction (HFrEF) is not known...

BACKGROUND: Catheter ablation (CA) therapy is the first choice treatment in adults with heart rhythm disturbances. The arrhythmias in adults are mainly conditioned by coronary disease. Etiology of arrhythmias in children is mostly associated with inherited heart disorders. According to the current guidelines the CA is widely used in children, indicating the need to make it more achievable in pediatric population. AIM: To assess efficacy and safety of CA in children with different types of arrhythmias on the initial learning curve at newly built Ablation Center in The Independent Pediatric Hospital of Medical University of Warsaw...
