The rapid progress of invasive therapeutic options for cardiac arrhythmias increases the need for accurate diagnostics. The surface electrocardiogram (ECG) is still the standard of noninvasive diagnostics but lacks atrial signal resolution. By contrast, esophageal electrocardiography (EECG) yields atrial signals of high amplitude and with a high signal-to-noise ratio. Esophageal electrocardiography has become fast and safe, but the mechanical constraints of esophageal measuring catheters and the "random" motion of the catheter inside the subject's esophagus limit the spatial resolution of EECG signals...

Purpose: Catheter ablation is an effective therapy for symptomatic atrial fibrillation (AF). The aim of this study was to assess the effect of ibutilide administration in patients with long standing persistent AF undergoing catheter ablation. Methods: We included 25 patients undergoing stepwise catheter ablation with ibutilide 1.0 mg infused prior to mapping and ablation as first step. Procedural and long-term outcomes were compared to a matched cohort of 25 patients in which ibutilide was not used but all other steps remained the same...

This study compared traditional short peripheral catheter (SPC) insertion methods with 2 vein visualization equipment models among a general patient population on a surgical step-down unit based on first-attempt success rates and the time required to achieve catheter insertion. The experiences of clinical nurses using the ultrasound and vein visualization equipment were also explored. No significant statistical differences were found between the insertion methods, based on 90 unique SPC insertion attempts. However, nurses reported that using the vein visualization equipment informed patient care, facilitated communication among members of the health care team, and facilitated second SPC insertion attempts...

Lactobacillus acidophilus fermentation products have been used to improve the performance of nursery pigs. However, research on the influence of this supplement on health is lacking. This study was designed to determine if feeding a Lactobacillus acidophilus fermentation product to weaned pigs would reduce stress and acute phase responses (APR) following a lipopolysaccharide (LPS) challenge. Pigs (n=30; 6.4±0.1 kg) were individually housed in stainless steel pens with ad libitum access to feed and water. Pigs were weighed upon arrival, assigned to one of three groups (n=10/treatment), and fed for 18 days: (1) Control, fed a non-medicated starter diet; (2) Control diet with the inclusion of a Lactobacillus acidophilus fermentation product at 1 kg/metric ton (SGX1) and (3) Control diet with the inclusion of a Lactobacillus acidophilus fermentation product at 2 kg/metric ton (SGX2)...

OBJECTIVE: During the past few years, there has been a surge in the use of catheter-directed thrombolysis (CDT) for acute pulmonary embolism (PE), in the form of either standard CDT or ultrasound-assisted CDT (usCDT). This is a systematic review and meta-analysis of all published series on contemporary CDT for acute PE seeking to determine their clinical efficacy, stratifying by PE severity and CDT modality. METHODS: A comprehensive MEDLINE and Embase search was performed to identify studies that reported outcomes of CDT for acute PE published from 2009 to July 2017...

PURPOSE: Current literature on clinical controversies surrounding the use of thrombolytic agents in patients with intermediate-risk pulmonary embolism (PE) is reviewed. SUMMARY: PE is a major cause of morbidity and mortality. When used in conjunction with anticoagulation, thrombolysis has been shown to reduce hemodynamic decompensation in select patients, but thrombolytic therapy is associated with high risks of bleeding and intracranial hemorrhage and its role in treating patients with intermediate-risk PE remains controversial...

REVIEW
Matthew A Chiarello, Akhilesh K Sista
Acute pulmonary embolism (PE) is a leading cause of morbidity and mortality in the United States. PE associated with right ventricular strain, termed submassive or intermediate-risk PE, is associated with an increased rate of clinical deterioration and short-term mortality. Trials have demonstrated systemic thrombolytics may improve patient outcomes, but they carry a risk of major hemorrhage. Catheter-directed thrombolysis (CDT) may offer similar efficacy to and a lower risk of catastrophic hemorrhage than systemic thrombolysis...

Due to the manifold treatment options for the management of acute pulmonary embolism, state-of-the-art management requires risk stratification for choosing the adapted treatment for each patient. Reperfusion therapy is an integral part of therapy for patients with pulmonary embolism at high risk for mortality, but its role in patients with intermediate risk pulmonary embolism is more debated. The largest amount of evidence exists for systemic thrombolysis, which is an efficient therapy, but at the prize of an increased bleeding risk...

Vitamin E, as all-rac α-tocopheryl-acetate (TAc), has a bioavailability of only 5.4% in swine and, therefore, is a poor vitamin E source. Tocopheryl-phosphate (TP) has been used successfully as a vitamin E source around 1940 but it was subsequently replaced by TAc as it was easier to manufacture. Recently, it has been proposed as an in vivo intermediate in vitamin E metabolism with possibly gene-regulatory functions. TP may be more bioavailable than TAc as intestinal hydrolysis and emulsification are not required...

Background and purpose Current large-bore catheters can be easily and safely placed in the intracranial vessels for the stabilization of microcatheters in several neurointervention scenarios. We considered that a novel 3.4 French catheter (TACTICS, Technorat Corporation, Aichi, Japan) might be useful for intermediate/distal access in a triaxial system. Here, we present our initial experience using the TACTICS catheter for treatment of intracranial aneurysms. Materials and methods A total of 35 endovascular coils were placed to embolize unruptured intracranial aneurysms of the anterior circulation using the TACTICS catheter between December 2016 and November 2017...
