Hemodynamic monitoring is essential during the treatment of the critically ill in order to address the hemodynamic alterations and assess the response to treatment. Traditionally classified causes of shock and underlying pathophysiological mechanisms are often neglected by resuscitative strategies included in the guidelines. Most of hemodynamic management focuses on the ability to early recognise patients susceptible to increase cardiac output (CO) and mean arterial pressure (MAP) after a defined fluid challenge by eliciting Starling's law of the heart, and less is known of the ones presenting in shock and not volume responsive...

Aims: Cardiac death is the leading cause of mortality in patients with sarcoidosis, yet cardiac involvement often remains undetected. Cardiovascular magnetic resonance imaging (CMR) and 18F-fluorodeoxyglucose (FDG)-positron emission tomography (PET) have been used to diagnose cardiac sarcoidosis (CS) yet never simultaneously in a cohort. This study sought to assess the diagnostic and prognostic utility of simultaneous hybrid cardiac PET/MR. Methods and results: Fifty-one consecutive patients with suspected CS (age 50 ± 13 years, 31 males) underwent simultaneous PET/MR following a high-fat/low-carbohydrate diet and 12-h fast...

BACKGROUND: While transcatheter device closure of ventricular septal defects (VSDs) is gaining popularity, concerns remain about adverse events; particularly heart block in peri-membranous VSDs (pmVSDs). The aim of this study is to ascertain outcomes of transcatheter device closure of pmVSDs through a meta-analysis of current literature. METHODS: A PubMed and Scopus search for studies in English on device closure of pmVSDs published till end-February 2017 was performed...

REVIEW
Nikhil Mehta, Robert Vannozzi
Lithium has been used for the treatment of bipolar disorder for more than 6 decades. Reports of cardiac side effects resulting in both benign electrocardiographic (ECG) changes and near fatal arrhythmias have been reported in the literature. A systematic literature search was conducted on 2 electronic databases-PubMed and Medline-for the time period between January 1970 and March 2016 using the key word "lithium," along with "electrocardiography" or "ECG." All articles and their references were then screened by title for relevance by 2 authors and a librarian...

INTRODUCTION: Hypertrophic cardiomyopathy (HCM) is a heterogeneous disease associated with sudden cardiac death (SCD) mainly due to ventricular tachycardia (VT) or fibrillation even though life-threatening bradycardia occurs. Risk stratification takes several variables into consideration including non-sustained VT (NSVT). An implantable cardioverter defibrillator effectively prevents SCD.Atrial fibrillation (AF) is common among patients with HCM and warrants anticoagulation even without conventional risk factors according to European guidelines...

Assessment of a permanent risk of life-threatening ventricular arrhythmia in patients with severely reduced left ventricular ejection fraction (LVEF <35%), e. g. after myocarditis, dilated cardiomyopathy, acute myocardial infarction, in patients with postpartum cardiomyopathy or implantable cardioverter-defibrillator (ICD) and cardiac resynchronization treatment plus defibrillator (CRT-D) infection with temporary explantation of the system is a medical challenge. This is time-consuming and unsafe because life-threatening ventricular arrhythmias may occur during the time of risk assessment...

Introduction Swallow syncope is a neurally mediated syncope. Multiple causes have been described in literature. A rare cause is arrhythmias. Only a limited amount of cases present the association of swallow syncope and third degree AV-block. Case presentation A 39-year-old man presented with episodes of presyncope while eating. Further medical history, physical examination, resting 12-lead ECG, cyclo-ergometry, transthoracic echocardiography and MRI of the heart were normal. 24 h Holter monitoring demonstrated high-grade third-degree atrioventricular (AV) block...

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...
