Amulet or Watchman Device for Percutaneous Left Atrial Appendage Closure: Primary Results of the SWISS-APERO Randomized Clinical Trial.

2022

Background:No study has so far compared Amulet with the new Watchman FLX in terms of residual left atrial appendage (LAA) patency or clinical outcomes in patients undergoing percutaneous LAA closure.Methods:In the investigator-initiated SWISS APERO trial (Comparison of Amulet Versus Watchman/FLX Device in Patients Undergoing Left Atrial Appendage Closure), patients undergoing LAA closure were randomly assigned (1:1) open label to receive Amulet or Watchman 2.5 or FLX (Watchman) across 8 European centers. The primary end point was the composite of justified crossover to a nonrandomized device during LAA closure procedure or residual LAA patency detected by cardiac computed tomography angiogr…

Simulation of left ventricular outflow tract (LVOT) obstruction in transcatheter mitral valve-in-ring replacement.

2020

Left ventricular outflow tract (LVOT) obstruction is a feared complication of transcatheter mitral valve replacement (TMVR). This procedure leads to an elongation of LVOT in the left ventricle (namely, the neoLVOT), ultimately portending hemodynamic impairment and death. This study sought to understand the biomechanical implications of LVOT obstruction in two patients who underwent TMVR as an "off-label" application of the Edwards SAPIEN 3 (S3) Ultra transcatheter heart valve (THV). A computational framework of TMVR was developed to assess the neoLVOT area and quantify the sub-aortic flow structure. We observed that the annuloplasty ring serves as the key anchor zone of S3 Ultra THV. A good…

Hemodynamic monitoring and management in patients undergoing high risk surgery: a survey among North American and European anesthesiologists

2011

Abstract Introduction Several studies have demonstrated that perioperative hemodynamic optimization has the ability to improve postoperative outcome in high-risk surgical patients. All of these studies aimed at optimizing cardiac output and/or oxygen delivery in the perioperative period. We conducted a survey with the American Society of Anesthesiologists (ASA) and the European Society of Anaesthesiology (ESA) to assess current hemodynamic management practices in patients undergoing high-risk surgery in Europe and in the United States. Methods A survey including 33 specific questions was emailed to 2,500 randomly selected active members of the ASA and to active ESA members. Results Overall,…

Incidence of peripheral intravenous catheter failure and complications in paediatric patients: Systematic review and meta analysis.

2020

Background: Most paediatric patients have at least one peripheral intravenous catheter insertion during their hospitalisation. Despite the important function of peripheral intravenous catheters for delivery of intravenous therapy, failure and complications rates are widely reported; however these results have not been synthesised. Objective: To provide an overall estimate of peripheral intravenous catheter failure and related complications in the paediatric population. Design: Systematic review and meta-analysis Data sources: The electronic databases, Cochrane Central Register of Controlled Trials, US National Library of Medicine National Institutes of Health, Cumulative Index of Nursing an…

Gefäßrekanalisation mit einem elektrischen Thermokauter-Katheter -In-vitro-Erfahrungen mit einem neuen Kathetersystem

1988

Recanalisation of arteriosclerotic occlusions by means of laser angioplasty, Kensey catheter and the "hot tip" catheter is undergoing early, successful clinical trials. The thermo-cautery catheter described in this paper uses the well known technique of cutting with high frequency electric currents in order to achieve vascular recanalisation. Seven attempts were made to recanalise occlusions at post mortem; four were successful, but perforation occurred in three. Histologically we found a narrow rim of carbonisation of tissues surrounded by a zone of homogenisation and a transitional zone.

A systematic approach to ultrasound-guided central venous catheter placement—desirable modifications

A life-threatening complication of parenteral nutrition: how to prevent cardiac tamponade?

2014

Complications caused by incorrect central venous insertion are numerous. Cardiac tamponade is a rare, but well-documented complication that is often lethal. We present the case of a patient with cardiac tamponade caused by incorrect tip position and infusion of hyperosmolar fluids such as for parenteral nutrition.

Infraclavicular access to the axillary vein-new possibilities for the catheterization of the central veins in the intensive care unit

2016

Central vein cannulation is one of the most commonly performed procedures in intensive care. Traditionally, the jugular and subclavian vein are recommended as the first choice option. Nevertheless, these attempts are not always obtainable for critically ill patients. For this reason, the axillary vein seems to be a rational alternative approach. In this narrative review, we evaluate the usefulness of the infraclavicular access to the axillary vein. The existing evidence suggests that infraclavicular approach to the axillary vein is a reliable method of central vein catheterization, especially when performed with ultrasound guidance.
