A 65-year-old patient underwent pericardiocentesis for cardiac tamponade after radiofrequency ablation for ventricular tachycardia. Subsequent to stabilization, the patient developed pneumopericardium, which was detected in the catheterization laboratory and managed successfully by pericardial aspiration.

Ventricular arrhythmias are common after left ventricular assist device implantation. Malposition of the inflow cannula is one of the few etiologies with a mechanically correctable defect. We present a case of intractable ventricular tachycardia that resolved after surgical repositioning of a HeartMate II inflow cannula. The diagnosis and management of this case demonstrate the utility of imaging studies for detecting inflow cannula malposition and the efficacy of inflow cannula repositioning for treatment.

Introduction: Symptoms like syncope or palpitations frequently present a diagnostic challenge. An implantable loop recorder (ILR) is an important aid in the management of these patients. Methods: A retrospective study of patients that underwent ILR implantation from November 2007 to 2014. For each patient the indication for implantation, baseline characteristics, previous study, complications, recorded tracing and interventions were evaluated. Results: A total of 62 patients were included, 50% men, with a mean age of 62...

Our purpose was to analyze evidence related to timing of cooling from studies of targeted temperature management (TTM) after return of spontaneous circulation (ROSC) after cardiac arrest and to recommend directions for future therapy optimization. We conducted a preliminary review of studies of both animals and patients treated with post-ROSC TTM and hypothesized that a more rapid cooling strategy in the absence of volume-adding cold infusions would provide improved outcomes in comparison with slower cooling...

A 79 year-old female was admitted to our hospital because of high serum creatine kinase level together with proximal muscle weakness and pain on grasping. MRI revealed inflammatory changes in femoral muscles on both sides. Muscle biopsy showed size irregularity of muscle cells, and necrosis and regeneration of fibers. Study of antibodies was also consistent with the diagnostic criteria of anti-signal recognition particle (anti-SRP) antibody-positive myopathy. On admission, the patient required pericardiocentesis for the management of exudative pericarditis...

Both cardiac resynchronization therapy with a pacemaker (CRT-P) and with a biventricular implantable cardioverter-defibrillator (CRT-D) are electrical treatment modalities validated for the management of chronic heart failure. There is no strong scientific evidence that a CRT-D must be offered to all candidates. Common sense should limit the prescription of these costly and complicated devices. The choice of CRT-P is currently acceptable. A direction to explore could be to downgrade from CRT-D to CRT-P at the time of battery depletion in patients with large reverse remodeling and no ventricular tachycardia and ventricular fibrillation detected...

Cardiac sarcoidosis is one of the uncommon causes of heart failure. Generally, it presents in the form of varying clinical manifestations ranging from asymptomatic to fatal arrhythmias such as ventricular tachycardia and complete heart block. It is difficult to make a diagnosis strictly based on clinical grounds. However, in the setting of extracardiac sarcoidosis and patients presenting with advanced heart block or ventricular arrhythmia, direct cardiac involvement should be suspected. The definitive diagnosis of cardiac sarcoidosis can be made from endomyocardial biopsy, but it is falling out of favor due to patchy myocardial involvement, considerable procedure-related risks, and advancement in additional imaging modalities...

Brugada syndrome (BrS), is a primary electrical disorder predisposing affected individuals to sudden cardiac death via the development of ventricular tachycardia and fibrillation (VT/VF). Originally, BrS was linked to mutations in the SCN5A, which encodes for the cardiac Na(+) channel. To date, variants in 19 genes have been implicated in this condition, with 11, 5, 3, and 1 genes affecting the Na(+), K(+), Ca(2+), and funny currents, respectively. Diagnosis of BrS is based on ECG criteria of coved- or saddle-shaped ST segment elevation and/or T-wave inversion with or without drug challenge...

Sudden cardiac death (SCD) is a rare but devastating complication of a number of underlying cardiovascular diseases. While coronary artery disease and acute myocardial infarction are the most common causes of SCD in older populations, inherited cardiac disorders comprise a substantial proportion of SCD cases aged less than 40 years. Inherited cardiac disorders include primary inherited arrhythmogenic disorders such as familial long QT syndrome (LQTS), Brugada syndrome (BrS), catecholaminergic polymorphic ventricular tachycardia (CPVT), and inherited cardiomyopathies, most commonly hypertrophic cardiomyopathy (HCM)...

Despite proven effectiveness in treating tachyarrhythmias, sotalol is proarrhythmic and can cause torsades de pointes. Given the emergence of studies that show no benefit from rhythm control strategies in managing atrial fibrillation, as well as the introduction of nonpharmacological approaches to treating arrhythmias, we felt it necessary to ascertain if there was any role for sotalol given its side effects. Review of the literature regarding sotalol use in the prevention and treatment of supraventricular and ventricular tachyarrhythmias seems to show that more effective and safer agents and nonpharmacological alternatives are currently available...

BACKGROUND: Ventricular tachycardia (VT) and ventricular fibrillation are the causes of approximately 300,000 deaths per year in the United States. VT is classified based on hemodynamic status and appearance. Stable, monomorphic VT treatment is controversial. OBJECTIVE: Our aim was to provide emergency physicians with an evidence-based review of the medical management of stable, monomorphic VT. DISCUSSION: Stable, monomorphic VT is part of a larger class of ventricular dysrhythmias defined by a rate of at least 120 beats/min with QRS > 120 ms without regularly occurring P:QRS association...

Thirty-nine year male had a history of road traffic accident with polytrauma. At emergency room he started having chest pain with ventricular tachycardia. He was subsequentially diagnosed with right coronary artery dissection secondary to blunt trauma which is an extremely rare cause of inferior wall myocardial infarction. After some dilemmas, he was ultimately treated with intravascular ultrasound guided coronary angioplasty with stenting and had an uneventful recovery.

Naxos disease is a rare autosomal recessive form of arrhythmogenic right ventricular cardiomyopathy (ARVC) with woolly hair and palmoplantar keratoderma. The cardiomyopathy presents by adolescence with syncope, ventricular tachycardia (VT) of left bundle branch block (LBBB) morphology, and/or ventricular fibrillation. The diagnosis and management of ARVC are at present in evolution; the recently published modified Task Force Criteria for diagnosis and International Task Force consensus statement for treatment of ARVC will hopefully bring about uniformity in recognition and management of Naxos disease as well...

BACKGROUND: Hypernatremia is a frequent occurrence among hospitalized patients. Severe hypernatremia is associated with mortality rates of over 60 %. Extreme hypernatremia, defined as sodium levels >190 mmol/l, is a rare occurrence. The literature on electrocardiographic changes occurring with this degree of hypernatremia is extremely scarce. We report the case of an 11-year-old Sri Lankan girl who presented with sodium levels of 226 mmol/l following infusion with 3 % hypertonic saline who developed diffuse QT prolongation leading to fatal ventricular tachycardia...

BACKGROUND: Pericardial decompression syndrome is defined as paradoxical hemodynamic instability, left ventricular or bi ventricular systolic dysfunction and pulmonary edema after pericardial fluid drainage. Pericardial Decompression Syndrome is an unexpected clinical scenario with an incidence less than 5% in all surgically or percutaneously managed pericardial tamponade patients. The aim of this manuscript was to describe a case with cardiac tamponade in whom acute biventricular heart failure and pulmonary edema developed after surgical creation of a pericardial window, and to discuss this case in light of the literature...

BACKGROUND: Percutaneous pulmonary valve implantation (PPVI) is utilized for dysfunctional right ventricular outflow tracts (RVOT) to relieve obstruction, regurgitation, and RV dysfunction. PPVI has not been reported to induce arrhythmias. This study is the first to report the incidence of ventricular tachycardia (VT) after PPVI. METHODS: This was a retrospective study of all patients who had PPVI at a single institution. All patients were admitted after PPVI for overnight telemetry monitoring...

Sudden cardiac death (SCD) is still among the leading causes of death in women and men, accounting for over 50% of all fatal cardiovascular events in the United States. Two arrhythmia mechanisms of SCD can be distinguished as follows: shockable rhythms (ventricular fibrillation and pulseless ventricular tachycardia) and non-shockable rhythms including asystole or pulseless electrical activity. The overall prognosis of cardiac arrest due to shockable rhythms is significantly better. While the majority of SCDs is attributed to coronary artery disease or other structural heart disease, no obvious cause can be identified in 5% of all events, and those events are labeled as sudden unexplained deaths (SUD)...

Recent advances have caused a major shift in the way ST-elevation myocardial infarctions are managed. This review explores the pharmacological and interventional techniques that have evidence for improving outcomes and the landmark trials that have sparked change. The new P2Y12 inhibitors, ticagrelor and prasugrel, have been shown to be superior to clopidogrel in STEMI patients undergoing primary percutaneous coronary intervention. Concurrently, many technical aspects of percutaneous coronary intervention have been further clarified by trial data, with bare-metal stents, routine thrombus aspiration and femoral access showing evidence of inferiority...
