REVIEW
Kristina Wasmer, Lars Eckardt
Catheter ablation of ventricular tachycardia (VT) is an established therapy for patients with ischemic cardiomyopathy to reduce implantable cardioverter-defibrillator (ICD) interventions and is a class I recommendation in international guidelines. Numerous publications confirm its value. Use of three-dimensional mapping systems with or without image integration is standard for ablation of complex arrhythmias. In patients with history of myocardial infarction they help to understand activation of reentrant circuits and are prerequisite for substrate mapping...

BACKGROUND: National practice guidelines do not provide clear recommendations on combination pharmacological regimens to reduce cardiothoracic surgery (CTS) postoperative atrial fibrillation (POAF). OBJECTIVE: This study examines if there is a reduction in POAF rates after implementing a perioperative prophylaxis guideline that includes amiodarone, β-blockers, and high-intensity statins. METHODS: Data were retrospectively collected on 400 adults (200 patients pre-guideline implementation and 200 patients post-guideline implementation) with a CHA2DS2-VASc (Congestive Heart Failure, Hypertension, Age, Diabetes Mellitus, and Vascular Disease) score of at least 3 points after CTS...

OBJECTIVE: To assess the evidence and make evidence-based recommendations for acute interventions to reduce brain injury in adult patients who are comatose after successful cardiopulmonary resuscitation. METHODS: Published literature from 1966 to August 29, 2016, was reviewed with evidence-based classification of relevant articles. RESULTS AND RECOMMENDATIONS: For patients who are comatose in whom the initial cardiac rhythm is either pulseless ventricular tachycardia (VT) or ventricular fibrillation (VF) after out-of-hospital cardiac arrest (OHCA), therapeutic hypothermia (TH; 32-34°C for 24 hours) is highly likely to be effective in improving functional neurologic outcome and survival compared with non-TH and should be offered (Level A)...

BACKGROUND: Sudden arrhythmic death syndrome (SADS) describes a sudden death with negative autopsy and toxicological analysis. Cardiac genetic disease is a likely etiology. OBJECTIVES: This study investigated the clinical utility and combined yield of post-mortem genetic testing (molecular autopsy) in cases of SADS and comprehensive clinical evaluation of surviving relatives. METHODS: We evaluated 302 expertly validated SADS cases with suitable DNA (median age: 24 years; 65% males) who underwent next-generation sequencing using an extended panel of 77 primary electrical disorder and cardiomyopathy genes...

BACKGROUND: Guidelines suggest that an abnormal blood potassium level is a relative contraindication to performing dobutamine stress echocardiography (DSE). However, this has not been previously studied. METHODS: We reviewed a consecutive series of patients who had potassium testing within 48 hours of undergoing DSE for the evaluation of myocardial ischemia over a 10-year period (N = 13,198). Normal potassium range in our laboratory is 3.6-5.2 mmol/L. Hemolyzed samples were not included...

OBJECTIVE: Although ED patients presenting with supraventricular tachycardia (SVT) are commonly investigated, the value of these investigations has been questioned. We aimed to determine the frequency and utility of investigations in patients with SVT. METHODS: We undertook an explicit retrospective medical record audit of patients with SVT who presented to a single ED (January 2004 to June 2014). Data on demographics, presenting complaints, investigations and outcomes were extracted...

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...

Malignant hyperthermia (MH) can be fatal if the crisis is not appropriately treated. It is an inherited disease usually triggered by the administration of volatile inhalational anesthetics and/or succinylcholine, a muscle relaxant. In a patient with suspected MH, the mechanism of calcium release from storage in the sarcoplasmic reticulum in the skeletal muscle is abnormally accelerated. Unexplained hypercarbia representing >55 mmHg of end-tidal carbon dioxide, tachycardia, and muscle rigidity (including masseter muscle rigidity) are early signs of the initiation of MH, because the metabolism is accelerated...

More than 70% of intensive care unit (ICU) patients experience heart rhythm disturbances, and these patients have correspondingly higher mortality rates. Consequently, one of the standards of care in ICUs is continuous electrocardiography monitoring. One of the potentially preventable dysrhythmic events is the occurrence of torsade de pointes ventricular tachycardia in the setting of acquired prolonged QT interval. This type of ventricular tachycardia can be malignant because it often progresses to ventricular fibrillation...

BACKGROUND: Both oral sucrose (OS) and nonnutritive sucking (NNS) are effective nonpharmacological methods to alleviate procedures pain in neonatal intensive care unit (NICU) newborns when they were used alone, but the combined effect of OS+NNS remains controversial. So, we conducted this study to evaluate the efficiency of NNS combined with oral sucrose on pain relief in NICU newborns undergoing painful procedures. METHODS: We searched PubMed, Ovid (Medline), Embase (Medline), Cochrane Central Library, and other resources such as Google Scholar, bibliographies of included literatures for all available articles...

BACKGROUND: Gamma-hydroxybutyrate (GHB) is a synthetic drug increasingly used by consumers of psychoactive substances. The sought after psychoactive effects of GHB have resulted in an increase in recreational use in Europe. GHB is considered to have a high dependence potential, and abrupt discontinuation after long-term use can result in a severe withdrawal syndrome. Despite a large number of publications related to GHB withdrawal and detoxification, to date, no evidence-based protocol or consensual international therapeutic guidelines are available (over and above the administration of benzodiazepines)...

OBJECTIVES: We sought to determine the safety of regadenoson stress testing in patients with PH. BACKGROUND: PH is increasingly recognized at more advanced ages. As many as one-third of patients with PH have coronary artery disease. Because of their physical limitations, patients with PH are unable to adequately exercise. Regadenoson can potentially have an adverse impact due to their tenuous hemodynamics. Current guidelines suggest performing a coronary angiography in patients with PH who have angina or multiple coronary risk factors...

Implantable loop recorders (ILR) do not play a pivotal role in the current guidelines on ventricular arrhythmias except in identifying rhythm-symptom correlations if ventricular arrhythmias are assumed. Before a decision for a pure diagnostic implantable device is made, a thorough arrhythmic risk assessment is of major importance due to the potential lethal outcome of ventricular arrhythmias. Nevertheless, some clinical circumstances exist where long-term monitoring by an ILR may add significant information in electrical heart diseases, in patients with ventricular arrhythmias, or structural heart diseases and a potential risk of ventricular arrhythmias...
