A 14-year-old neutered male crossbreed dog was presented for weakness, cough and weight loss. Cardiac auscultation revealed tachycardia, arrhythmia and a grade V/VI left apical systolic heart murmur. Thoracic radiographs showed a large homogeneous soft tissue opacity in close contact with the cardiac silhouette in the left cranioventral mediastinum. Cardiac evaluation showed atrial fibrillation, degenerative mitral valve disease and a dilated left auricular appendage outside the pericardium consistent with herniation through a partial pericardial defect...

A pre-thrombotic (hypercoagulable) state is observed in patients with thrombophilia, malignant diseases, pregnancy, auricular fibrillation, connective tissue diseases, prosthetic replacement arthroplasty, infection, or old age, and these states are also caused by dehydration, remaining in the same position for a long time, or estrogen drugs. Such patients have a high risk of developing thrombosis. The pre-thrombotic state is diagnosed or excluded by fibrin-related markers (FRMs), such as soluble fibrin (SF), fibrinogen and fibrin degradation products (FDP), and D-dimer...

OBJECTIVE Facial palsy is a well-known functional and esthetic problem that bothers most patients and affects their social relationships. When the time between the onset of paralysis and patient presentation is less than 18 months and the proximal stump of the injured facial nerve is not available, another nerve must be anastomosed to the facial nerve to reactivate its function. The masseteric nerve has recently gained popularity over the classic hypoglossus nerve as a new motor source because of its lower associated morbidity rate and the relative ease with which the patient can activate it...

The cardiac autonomic nervous system has been known to play an important role in the development and progression of cardiovascular diseases. Autonomic modulation by electrical stimulation of the parasympathetic nervous system, which increases the parasympathetic activity and suppresses the sympathetic activity, is emerging as a therapeutic strategy for the treatment of cardiovascular diseases. Here, we review the recent literature on autonomic modulation by electrical stimulation of the parasympathetic nervous system, including vagus nerve stimulation, transcutaneous auricular vagal stimulation, spinal cord stimulation, and ganglionated plexi stimulation, in the treatment of heart failure, atrial fibrillation, and ventricular arrhythmias...

A 69-year-old woman with a medical history of stroke and an ICD device due to torsade de pointes was admitted with a right basal ganglia haemorrhage. In the hours after admission the patient's condition severely declined and she developed fever, hypertension and flushing consistent with autonomic dysfunction with sympathetic storming. ICD interrogation revealed electrical storm with 138 appropriate shocks delivered at the night of admission. We wish to draw attention to the close link between brain and heart, which in predisposed patients with a new stroke can cause malignant arrhythmias...

INTRODUCTION AND OBJECTIVES: Dabigatran is an anticoagulant drug and a direct thrombin inhibitor and has been approved for the prevention of ischaemic stroke secondary to nonvalvularauricular auricular fibrillation. The aim of this study was to determine the efficacy of dabigatran in clinical practice for preventing cerebral ischaemic events associated with nonvalvularauricular auricular fibrillation, as well as its tolerance and safety profile. MATERIAL AND METHODS: A descriptive and retrospective study was conducted, which included all patients who started anticoagulant treatment with dabigatran between November 2011 and September 2012...

AIMS: Prevalence of left appendage thrombosis ranges from 6 to 18% in persistent atrial fibrillation (AF). Few and low sample size studies have assessed left and right atrial thrombosis in persistent atrial flutter (AFL) and a wide variety of frequencies, from 1 to 21%, has been reported. The aim of this study was to evaluate the prevalence of atrial appendage thrombosis in a large population of patients undergoing transoesophageal echocardiography (TEE)-guided cardioversion (CV) for recent AFL onset and compare it with AF...

TASK-1 channels have emerged as promising drug targets against atrial fibrillation, the most common arrhythmia in the elderly. While TASK-3, the closest relative of TASK-1, was previously not described in cardiac tissue, we found a very prominent expression of TASK-3 in right human auricles. Immunocytochemistry experiments of human right auricular cardiomyocytes showed that TASK-3 is primarily localized at the plasma membrane. Single-channel recordings of right human auricles in the cell-attached mode, using divalent-cation-free solutions, revealed a TASK-1-like channel with a single-channel conductance of about 30pS...

INTRODUCTION AND OBJECTIVES: To determine the degree of control of patients on anticoagulants in follow-up in primary care in Galicia and investigate whether time in therapeutic range as estimated using the number of acceptable controls is comparable with the estimation using the Rosendaal method. METHODS: Transversal study that included patients older than 65 years, diagnosed with nonvalvular atrial fibrillation, on anticoagulants for at least 1 year. Control was considered good when the time in therapeutic range was greater than 65%, estimated by the Rosendaal method, or 60% estimated by the number of acceptable controls...

OBJECTIVE: SK channels are existed in hearts of mouse, rat, and human. Biochemical evidence indicates that SK2 channels are expressed more in atrial than in ventricular tissue. SK channels are highly sensitive to the calcium concentration of the pipette solution. In the present study, performed whole-cell patch clamp was used to detect the calcium sensitivity of small conductance Ca(2+)-activated K+ channels (SK) currents between sinus ryhthm (SR) and auricular fibrillation (AF). METHODS: The patients who accepted cardiopulmonary bypass were divided into two groups: 21 patients with SR and 8 patients with AF...

In patients with non-rheumatic atrial fibrillation, efficacy of stroke prevention with oral anticoagulant therapy has been proved. However, there are patients who are not candidates for long-term oral anticoagulation, namely patients with high risk of bleeding complications or previous hemorrhagic stroke. In those patients, percutaneous closure of left auricular appendage (LAA) has demonstrated to be safe and efficacious preventing cardioembolic events. However, some LAA are too large or too fragile and they may not be suitable for occlusion...

Bacterial nanocellulose (BNC), synthesized by the bacterium Gluconacetobacter xylinus, is composed of highly hydrated fibrils (99 % water) with high mechanical strength. These exceptional material properties make BNC a novel biomaterial for many potential medical and tissue engineering applications. Recently, BNC with cellulose content of 15 % has been proposed as an implant material for auricular cartilage replacement, since it matches the mechanical requirements of human auricular cartilage. This study investigates the biocompatibility of BNC with increased cellulose content (17 %) to evaluate its response in vitro and in vivo...
