However, in some situations the VA site of origin or substrate may be intramural or epicardial in nature. In these cases... |
24,584 | Radiofrequency Ablation Strategies for Intramural Ventricular Arrhythmias. | Catheter ablation is an established treatment strategy for ventricular arrhythmias. However, the presence of intramural substrate poses challenges with mapping and delivery of radiofrequency energy, limiting overall success of catheter ablation. Advances over the past decade have improved our understanding of intramura... |
24,585 | Stellate ganglion blockade with percutaneous bupivacaine injection followed with surgical denervation in the management of electrical storm. | Electrical storm is a life-threatening medical emergency that requires immediate diagnosis and treatment. It can remain a clinical challenge despite anti-arrhythmic drugs and catheter ablation therapies. Autonomic modulation techniques have gained increased recognition in the treatment of refractory electrical storm ca... |
24,586 | Asymptomatic ventricular fibrillation in continuous flow left-ventricular assist device. | Left ventricular assist devices (LVADs) have increased survival for heart failure patients. Individuals with LVADs are a growing patient population with frequent complications and Emergency Department (ED) visits. A 50-year-old female presented to the ED due to a low flow alarm on her LVAD. Upon arrival in the ED she w... |
24,587 | An 80-Year-Old Man With Persistent Enterococcus faecalis Bacteremia. | An 80-year old man presented to the ED after being found down in his home. He had gone to the restroom to perform straight catheterization, as he normally does for his enlarged prostate, and was found slumped over and confused. On arrival to the ED, he was found to be in atrial fibrillation with rapid ventricular respo... |
24,588 | Prognostic relevance of elevated plasma osmolality on admission in acute decompensated heart failure with preserved ejection fraction: insights from PURSUIT-HFpEF registry. | Complicated pathophysiology makes it difficult to identify the prognosis of heart failure with preserved ejection fraction (HFpEF). While plasma osmolality has been reported to have prognostic importance, mainly in heart failure with reduced ejection fraction (HFrEF), its prognostic meaning for HFpEF has not been eluci... |
24,589 | Safety and Efficacy of Landiolol Hydrochloride in Children with Tachyarrhythmia of Various Etiologies. | The safety and efficacy of landiolol have not been fully elucidated in pediatric patients. This study aimed to clarify the safety and efficacy of landiolol in a pediatric cohort. We retrospectively assessed the clinical features of 21 pediatric patients who were administered landiolol at our hospital. We also investiga... |
24,590 | Effect of Amplitude Spectral Area on Termination of Fibrillation and Outcomes in Pediatric Cardiac Arrest. | Background Amplitude spectral area (AMSA) predicts termination of fibrillation (TOF) with return of spontaneous circulation (ROSC) and survival in adults but has not been studied in pediatric cardiac arrest. We characterized AMSA during pediatric cardiac arrest from a Pediatric Resuscitation Quality Collaborative and h... |
24,591 | CHA<sub>2</sub>DS<sub>2</sub>-VASC score predicts coronary artery disease progression and mortality after ventricular arrhythmia in patients with implantable cardioverter-defibrillator. | The CHA2</sub>DS2</sub>-VASC score has expanded its use beyond the initial purpose of predicting the risk of stroke in patients with atrial fibrillation. We aimed to investigate the value of the CHA2</sub>DS2</sub>-VASC score as a risk assessment tool to predict relevant coronary artery disease (CAD) leading to percuta... |
24,592 | The relation between the atrial blood supply and the complexity of acute atrial fibrillation. | Patients with a history of myocardial infarction and coronary artery disease (CAD) have a higher risk of developing AF. Conversely, patients with atrial fibrillation (AF) have a higher risk of developing myocardial infarction, suggesting a link in underlying pathophysiology. The aim of this study was to assess whether ... |
24,593 | The Relationship of Dehydration and Body Mass Index With the Occurrence of Atrial Fibrillation in Heart Failure Patients. | <b>Purpose:</b> The aim of the study was to assess the relationship of dehydration, body mass index (BMI) and other indices with the occurrence of atrial fibrillation (AF) in heart failure (HF) patients. <b>Methods:</b> The study included 113 patients [median age 64 years; 57.52% male] hospitalized due to HF. Baseline ... |
24,594 | Proarrhythmia in a Patient With Heart Failure on Therapy With Amiodarone. | The deterioration of hepatorenal function due to worsening congestion is relatively common in acute heart failure and carries an independent adverse prognosis. In some patients, the risk of proarrhythmia is increased due to impaired drug metabolism. We described a patient with acute heart failure, polymorphic ventricul... |
24,595 | Echocardiographic Measurement of Left Atrial Strain　- A Key Requirement in Clinical Practice. | Unlike the left ventricle (LV), the left atrium (LA) has a thin-walled structure and has been regarded as a simple conduit chamber. However, the unique function of the LA to modulate LV filling has recently drawn much attention. Because LA structure and function are directly influenced by the LV filling pressure, LA as... |
24,596 | Adaptive Servo-ventilation Therapy Results in the Prevention of Arrhythmias in Patients with Heart Failure Due to Ischemic Heart Disease. | Objective Whether or not adaptive servo-ventilation (ASV) is effective in preventing arrhythmias in patients with heart failure (HF) due to ischemic heart disease (IHD) is unclear. This study estimated the effects of ASV therapy on arrhythmias in patients with HF due to IHD. Methods One hundred and forty-one consecutiv... |
24,597 | Impact of Atrial Fibrillation on Hospitalization Outcomes of Heart Failure in Patients ≥ 60 Years with Implantable Cardioverter Defibrillator. | The impact of atrial fibrillation (AF) on the hospitalization outcomes in patients ≥ 60 years of age with implantable cardioverter defibrillators (ICD) is not well studied. We queried the National Inpatient Sample database for all patients aged ≥ 60 who had a history of ICD placement, and were admitted wi... |
24,598 | Standardized post-resuscitation damage assessment of two mechanical chest compression devices: a prospective randomized large animal trial. | Mechanical chest compression devices are accepted alternatives for cardiopulmonary resuscitation (CPR) under specific circumstances. Current devices lack prospective and comparative data on their specific cardiovascular effects and potential for severe thoracic injuries.</AbstractText>To compare CPR effectiveness and t... |
