A 20-year-old warmblood breeding stallion presented to a University practice for semen collection and evaluation was incidentally diagnosed with atrial fibrillation (AF). Electrocardiogram recordings during breeding revealed inappropriately rapid tachycardia and occasional ventricular premature depolarizations/aberrant ventricular conduction. Transvenous electrical cardioversion was performed. After successful cardioversion the horse displayed supraventricular ectopy and atrial contractile dysfunction and was administered sotalol hydrochloride in an attempt to decrease the risk of AF recurrence...

Congenitally corrected transposition of the great arteries is a rare form of congenital heart disease in which the persistence of the right ventricle as the systemic ventricle leads to heart failure, tricuspid valve insufficiency, and arrhythmia. Supraventricular arrhythmias are especially common in these patients. We discuss the anesthetic management of a 33-year-old patient with congenitally corrected transposition of the great arteries who required a ventricular assist device to maintain cardiac output during ablation of supraventricular tachyarrythmia...

Cardiovascular disease continued to be a leading killer world widely. Each year, about 400,000 cases of sudden cardiac arrest are reported in the U.S. alone. Clinically, radio-frequency ablative procedure has become widely applied in the treatment of ventricular arrhythmia. Non-invasive approaches have been demonstrated to be able to provide important information on the arrhythmogenesis and potentially assist in the clinical practice. In this work, we develop and validate a novel temporal sparse based imaging method, Cardiac Electrical Sparse Imaging (CESI)...

One hundred years have elapsed since Thomas Jonnesco performed the first left cardiac sympathetic denervation (LCSD) in a patient with unmanageable angina pectoris and ventricular tachyarrhythmias, and the progress in the field has surpassed imagination. Here we will review the historic basis of cardiac sympathectomy for the management of life-threatening arrhythmias and will then discuss the often forgotten critical experimental studies that provided the rationale for the amazing growth of its role in clinical management...

INTRODUCTION: The cardiac sodium channel SCN5A regulates atrioventricular and ventricular depolarization as well as cardiac conduction. Patients with cardiac electrical abnormalities have an increased risk of sudden cardiac death (SCD) and cardio-embolic stroke. Optimal management of cardiac disease includes the understanding of association between the causative mutations and the clinical phenotype. A 12-lead electrocardiogram (ECG) is an easy and inexpensive tool for finding risk patients...

There is a subset of patients who have recurrent ventricular tachycardia despite optimal medical management with pharmacologic therapy and catheter ablation. The cardiac sympathetic nervous system is responsible for triggering and perpetuating ventricular arrhythmias, and surgery can reduce the sympathetic stimulation to the heart. Evidence supports the use of left cardiac sympathetic denervation in recurrent ventricular arrhythmias for long QT syndrome and catecholaminergic polymorphic ventricular tachycardia...

Extracorporeal life support (ECLS) is a very effective bridging therapy in patients with refractory ventricular tachycardia (VT) associated with cardiogenic shock. A moribund patient in extremis, is not amenable to optimization by standard ACC/AHA guidelines. New approaches and novel salvage techniques are necessary to improve outcomes in patients with refractory clinical settings such as malignant ventricular arrhythmias, cardiac arrest, cardiogenic shock and/or pulmonary failure until further management options are explored...

BACKGROUND: Implantable cardioverter defibrillator (ICD) is the most important management for prevention of sudden cardiac death (SCD) in patients with arrhythmogenic right ventricular cardiomyopathy (ARVC). However, some patients may receive multiple ICD therapies in a short period, a condition referred as "electrical storm". OBJECTIVES: This study aimed to determine the prevalence, therapeutic options, and prognostic implications of ES in ARVC patients with an ICD...

BACKGROUND: Spontaneous coronary artery dissection (SCAD) is an infrequent but important cause of myocardial infarction (MI) especially in younger women. However, the clinical presentation and the acuity of symptoms prompting invasive management in SCAD patients have not been described. Understanding these presenting features may improve SCAD diagnosis and management. METHODS: We reviewed SCAD patients who were prospectively followed at the Vancouver General Hospital SCAD Clinic...

Interventricular membranous septal (IVMS) aneurysm is a rare condition with no accurate incidence. It is known to be associated with 0.3 % of congenital heart disease and 19 % of ventricular septal defects. IVMS aneurysm is often asymptomatic but can be complicated with right ventricular obstruction, rupture, thromboembolism, and conduction defects. Clinicians and radiologist should be aware about this rare clinical entity and evaluation of any possible underlying cardiac abnormalities should be performed. Conservative management with close follow up is the mainstay of management in the absence of complication...

The incidence of sudden cardiac death, predominantly caused by ventricular tachycardia and ventricular fibrillation, is high in patients with congestive heart failure. Implantable cardiac defibrillators have improved survival in this population but defibrillator shocks can lead to low quality of life and heart failure progression. The current management of recurrent ventricular tachycardia includes ablation and anti-arrhythmic drugs and both are associated with high recurrence rates. Better understanding the mechanism of ventricular tachycardia allowing individualization of treatment may improve outcomes...

Malignant ventricular arrhythmias and sudden cardiac death may late happen in repaired tetralogy of Fallot, although probably less frequently than previously thought, especially with the advent of new surgical techniques/management. Ventricular tachycardias are caused by reentry around the surgical scars/patches and valves. Many predictive factors have been proposed, which suffer from poor accuracy. There is currently no recommended indication for prophylactic implantable cardioverter defibrillator implantation-except maybe in the case of multiple risk factors-while radiofrequncy ablation may be proposed in secondary prevention with or even without a back-up implantable cardioverter defibrillator in selected cases...

PURPOSE: Few outcome data are available about temperature management after intraoperative cardiac arrest (IOCA). We describe targeted temperature management (TTM) (32-34 °C) modalities, adverse events, and association with 1-year functional outcome in patients with IOCA. METHODS: Patients admitted to 11 ICUs after IOCA in 2008-2013 were studied retrospectively. The main outcome measure was 1-year functional outcome. RESULTS: Of the 101 patients [35 women and 66 men; median age, 62 years (interquartile range, 42-72)], 68 (67...

Neurological injury is often associated with cardiac abnormalities, including electrophysiological issues. Cardioversion of acute atrial fibrillation (<48h' duration) without anticoagulation carries about a 0.7% risk of thromboembolism. There is limited data on managing acute atrial fibrillation specifically in the neuroscience intensive care unit (NSICU) setting. We sought to determine the safety of using intravenous (IV) amiodarone for restoring sinus rhythm in patients with presumed new onset atrial or ventricular tachycardia after neurological injury...

Idiopathic epicardial ventricular tachycardias (VTs) account for 9% of idiopathic VTs. The recognition of this entity is important, as a minimally invasive ablation procedure performed exclusively through the coronary sinus branches may be considered, avoiding the potential risks associated with access to the left ventricular endocardium, the aortic root, and the pericardial space. The electrocardiographic features and therapeutic management of this rare form of tachycardia are discussed.

Anesthesiologists frequently see asymptomatic patients with diastolic dysfunction or heart failure for various surgeries. These patients typically show normal systolic function but abnormal diastolic parameters in their preoperative echocardiographic evaluations. The symptoms that are sometimes seen are similar to those of chronic obstructive pulmonary disease. Patients with diastolic dysfunction, and even with diastolic heart failure, have the potential to develop a hypertensive crisis or pulmonary congestion...

A 75-year-old man presented with dizziness and fatigue secondary to ventricular and supraventricular arrhythmias. He underwent an elective ablation but continued to suffer from ventricular tachycardia with cardiovascular instability despite antiarrhythmic therapy with multiple agents. The patient continued to develop episodes of ventricular tachycardia and an episode of ventricular fibrillation. Electrical storm encompasses a situation of cardiac instability which may present as several episodes of ventricular tachycardia or ventricular fibrillation in a short period...
