Prolonged left atrial electromechanical conduction time is related with atrial electrical remodeling, and is predictive of the development of atrial fibrillation. The aim of our study was to examine whether left atrial electromechanical conduction time (EMT) and left atrial strain as measured by speckle tracking echocardiography (STE) are predictors for the development of atrial fibrillation (AF) in patients with mitral stenosis (MS) at 5-year follow-up. A total of 81 patients (61% females; mean age 38.1 ± 12...

Creutzfeldt-Jakob disease (CJD) is a rare, degenerative, invariably fatal brain disorder. CJD usually appears in later life and runs a rapid course. Typically, the onset of symptoms occurs about age 60 and about 90% of individuals die within one year. We report a case of 67-year-old male presented with progressive aphasia, confusion, dysphagia and inability to carry out activities of daily life (ADLs) over a period of three to four weeks. The patient had past medical history of chronic atrial fibrillation and hypertension...

BACKGROUND In the modern antibiotic era, Streptococcus agalactiae infection of the endocardium and pericardial space is a rare occurrence. However, once the disease spreads it can lead to life-threatening illness despite advances in diagnostic and treatment modalities, partly because the symptoms and signs associated with pericarditis are frequently missing, and due to the rarity of the disease, diagnosis is often overlooked. We report an extremely rare case of purulent pericarditis caused by Streptococcus agalactiae...

In spite of difficult anatomic access for tumors of mediastinum, surgical resection remains the best diagnostic and therapeutic approach. Widespread acceptance of video-assisted thoracoscopy (VATS) is restricted by the limiting nature of instruments and suboptimal visualization. Robotic assisted minimally invasive surgery seems to hold most promise in remote, narrow anatomical regions. After obtaining approval from Institutional Review Board (IRB), a retrospective review of prospectively collected database on patients that underwent Robotic VATS between 2009 and 2013 was conducted...

The most effective treatment of patients with stroke due to tandem occlusion is still unclear. We report the case of a man with stroke due to tandem internal carotid artery/middle cerebral artery occlusion, who underwent initially ineffective intravenous thrombolysis (IVT) and endovascular treatment. Early anticoagulation with apixaban was started after 48 h of IVT, given a newly diagnosed nonvalvular atrial fibrillation. Spontaneous partial recanalization of the cervical internal carotid artery was noted, and carotid endarterectomy was performed 72 h after IVT and 8 h after the last dose of apixaban...

An 84-year-old man presented 5 years following bioprosthetic mitral valve replacement with three months of worsening dyspnea on exertion. A new mitral stenosis murmur was noted on physical examination, and an electrocardiogram revealed newly recognized atrial fibrillation. Severe mitral stenosis (mean gradient = 13 mmHg) was confirmed by transthoracic echocardiography. Transesophageal echocardiography revealed markedly thickened mitral bioprosthetic leaflets with limited mobility, and a massive left atrial thrombus (> 4 cm in diameter) (see Figures 1A-D, and video files 1-4)...

BACKGROUND: Mutations in SCN5A, the gene encoding the α-subunit of the cardiac sodium channel (NaV1.5), are associated with a broad spectrum of inherited cardiac arrhythmia disorders. The purpose of this study was to identify the genetic and functional determinants underlying a Dutch family that presented with a combined phenotype of ventricular arrhythmias with a likely adrenergic component, either in isolation or in combination with a mildly decreased heart function and early onset (<55years) atrial fibrillation...

BACKGROUND: Since stroke patients with nonvalvular atrial fibrillation (NVAF) have poor outcomes in general, the prediction of outcomes following discharge is of utmost concern for these patients. We previously reported that brain natriuretic peptide (BNP) levels were significantly higher in NVAF patients with larger infarcts, higher modified Rankin Scale (mRS) score, and higher CHADS2 score. In the present study, we evaluated an array of variables, including BNP, in order to determine significant predictors for functional outcome in patients with NVAF after acute ischemic stroke (AIS)...

BACKGROUND AND PURPOSE: The aim was to evaluate the relationship between distal hyperintense vessel sign (HVS) and early neurological deterioration (END) in acute ischaemic stroke with large vessel steno-occlusion. METHODS: Acute ischaemic stroke patients with symptomatic severe steno-occlusion in the middle cerebral artery or internal carotid artery were recruited within 24 h from symptom onset. Stroke outcomes were evaluated using the National Institutes of Health Stroke Scale (NIHSS) score at the time of admission and at 72 h and 7 days...

BACKGROUND: Familial sick sinus syndrome (SSS) is often attributable to mutations in genes encoding the cardiac Na channel SCN5A and pacemaker channel HCN4. We previously found that SSS with SCN5A mutations shows early onset of manifestations and male predominance. Despite recent reports on the complications of atrial fibrillation (AF) and left ventricular noncompaction (LVNC) in patients with SSS caused by HCN4 mutations, their overall clinical spectrum remains unknown. OBJECTIVE: The purpose of this study was to investigate the clinical and demographic features of SSS patients carrying HCN4 mutations...

This study was attempted to address the association between early onset cataract (EOC) and ischemic stroke. Using the Longitudinal Health Insurance Database 2000, we established an EOC cohort and a comparison cohort by using 4-fold propensity score matching according to age, gender and comorbidities to detect the incidence of ischemic stroke. A Cox model was used to express the risk of ischemic stroke for the EOC patients compared with the comparison cohort. After adjusting for age, gender and comorbidities of hypertension, diabetes mellitus, hyperlipidemia, coronary artery disease, asthma, chronic obstructive pulmonary disease, chronic kidney disease, heart failure, obesity, and atrial fibrillation, the EOC patients had a 1...

BACKGROUND: Fabry disease (FD) is characterized by the accumulation of sphingolipids in multiple organs, including the left atrium. It is uncertain if the left atrial (LA) reservoir, conduit, and contractile functions evaluated by speckle-tracking echocardiography are affected in Fabry cardiomyopathy and whether enzyme replacement therapy can improve LA function. METHODS: In this retrospective cohort study, LA strain, strain rates, and phasic LA volumes were studied in 50 patients with FD and compared with values in 50 healthy control subjects...

Both anemia and atrial fibrillation are common in older people and their prevalence is age dependent which increases as population ages. Anemia, especially acute onset, predisposes to new onset atrial fibrillation which is likely to be mediated through inducing heart failure first and this predisposition seems to be potentiated by the presence of renal impairment. Anemia adds to the comorbidity burden of patients with atrial fibrillation and independently increases the risks of adverse outcomes such as increased hospitalization, mortality, bleeding and thromboembolic events...

Knowledge of the mechanism underlying post-operative atrial fibrillation (PoAF) is essential for development of preventive measures. The incidence and characteristics of both PoAF and supraventricular premature beats triggering PoAF, their interrelationship and alterations over time have never been examined. The goal of this study is therefore to examine the correlation between the incidence and characteristics of supraventricular premature beats (SVPBs) and PoAF episodes in patients undergoing CABG in the first five post-operative days...

AIMS: It is known that type 2 diabetic patients are at high risk of atrial fibrillation (AF). However, the early echocardiographic determinants of AF vulnerability in this patient population remain poorly known. METHODS: We followed-up for 2years a sample of 180 consecutive outpatients with type 2 diabetes, who were free from AF and ischemic heart disease at baseline. All patients underwent a baseline echocardiographic-Doppler evaluation with tissue Doppler and 2-D strain analysis...

BACKGROUND: The objective of this study was to compare outcomes of patients with previous solid organ transplant with those of a pair-matched population. METHODS: Data from our prospectively maintained cardiac surgery registry were obtained and identified 70 transplant recipients (21 hepatic, 49 renal) who were operated on at our department of cardiac surgery between 2000 and 2013; they formed the transplant group. Those patients were pair-matched regarding age, sex, and cardinal cardiac risk factors to form the pair-matched group...

Nuria Ortigosa, Antonio Galbis, Carmen Fernández, Óscar Cano
In this study, we propose a new classification method for early differentiation of paroxysmal and persistent atrial fibrillation episodes, i.e. those which spontaneously or with external intervention will return to sinus rhythm within 7 days of onset from the ones where the arrhythmia is sustained for more than 7 days. Today, clinicians provide patients classification once the course of the arrhythmia has been disclosed. This classification problem is dealt with in this study. We study a sparse representation of surface electrocardiogram signals by means of Gabor frames and afterwards we apply a linear discriminant analysis...

Atrial fibrillation (AF) is a common clinically significant cardiac arrhythmia. This phase 3 randomized, double-blind, placebo-controlled trial assessed the efficacy and safety of vernakalant hydrochloride for the pharmacological conversion of AF to sinus rhythm in patients with recent-onset (>3 hours to ≤7 days) symptomatic AF from the Asia-Pacific region. Patients received an infusion of vernakalant (3 mg/kg) or placebo for 10 minutes. If AF had not been terminated 15 minutes later, a second infusion of vernakalant (2 mg/kg) or placebo for 15 minutes was administered...
