The gold(I)-catalyzed hydrogen isotope exchange reaction on indoles and related heterocycles is described under mild conditions and low catalyst loadings, using CDOD and DO as readily available deuterium sources. C3-unsubstituted indoles are labeled at the C3 position with exquisite regioselectivity, while C3-substituted indoles are labeled at the C2 position. The method is also applicable to the regioselective tritiation of indoles.

Objective: Atrial cardiomyopathy is closely associated with atrial fibrillation (AF), and some patients exhibit no dysfunction at rest but demonstrate evident changes in left atrial (LA) function and LA volume during exercise. This study aimed to identify distinguishing signs during exercise stress echocardiography (ESE) among patients in sinus rhythm (SR), with and without history of paroxysmal/persistent AF (PAF).

Methods: A prospective cohort of 1055 patients in SR was enrolled across 12 centers.

Mesalazine represents a key treatment for intestinal bowel diseases and only in rare cases produces cardiac toxicity, with a not completely known mechanism. We report a case of a 25-year-old man with a first episode of myocarditis after 2 weeks from the first mesalazine intake, documented also by a characteristic cardiac magnetic resonance pattern. Then, after less than 1 month, he suffered myocarditis recurrence and so, guided by a multidisciplinary team evaluation, in the suspicion of mesalazine-induced myocarditis, the drug was promptly stopped, with consequent recovery of cardiac damage.

Background: Frailty and comorbidity influence the therapeutic approach in everyday clinical practice. The DOACs genericization opens a reflection on their differences from a pharmacological and bioavailability point of view, particularly in elderly frail patients. The aim of this project was to create a national Delphi consensus on the topic of the use of DOACs for atrial fibrillation (AF) in such patients, in light of the genericization of the class.

Article Synopsis
  • - The study aimed to assess how the presence of raphe (a type of anatomical feature) in patients with bicuspid aortic valve (BAV) correlates with valve dysfunction, aortopathy, and the likelihood of needing aortic valve surgery.
  • - Researchers analyzed 695 BAV patients, finding that those with raphe experienced more moderate to severe aortic stenosis and a higher prevalence of aortopathy, particularly Type B, compared to those without raphe.
  • - The results indicated that having raphe significantly raises the odds of requiring aortic valve surgery within three years, highlighting the importance of monitoring patients with this anatomical feature.

Article Synopsis
  • The Italian Society of Echography and Cardiovascular Imaging (SIECVI) conducted a national survey to investigate stress echocardiography (SE) practices across Italy, collecting data from 228 laboratories in November 2022.
  • The survey revealed that out of 179 centers performing SE, most were located in northern Italy, and the study categorized them into low, moderate, and high volume of activity based on the number of SE examinations.
  • Key findings indicated differences in the use of stressors, with a tendency for high-volume centers to employ multiple stress techniques and incorporate advanced evaluations like coronary flow velocity reserve (CFVR) more frequently than low and moderate volume centers.

Background: Optimising periprocedural management of direct oral anticoagulation in patients with atrial fibrillation on chronic treatment undergoing major surgeries is an important aspect of balancing the risk of surgery-related bleeding with the risk of thromboembolic events, which may vary by surgery type.

Methods: This subanalysis of the prospective EMIT-AF/VTE programme assessed periprocedural-edoxaban management, according to physicians' decisions, and bleeding and thromboembolic event rates in patients who underwent major vs. nonmajor surgeries.

Article Synopsis
  • Left atrial myopathy is common in chronic coronary syndromes and can be triggered by stress, especially in patients with atrial fibrillation.
  • A study involving 3042 patients assessed left atrial volume and function at rest and during stress, showing that left atrial volume index increased and LA strain decreased as patients progressed from sinus rhythm to permanent atrial fibrillation.
  • The findings highlighted that both paroxysmal and permanent AF are linked to greater left atrial dilation and dysfunction, which correlates with more instances of stress-induced ischemia and pulmonary congestion.

Patients treated with edoxaban may require diagnostic and therapeutic procedures that involve edoxaban interruption. Although heparin bridging strategies are not recommended, heparin is frequently used in clinical practice. However, whether heparin use decreases thromboembolic risk remains unclear, and the potential for increased periprocedural bleeding remains a concern.

Introduction: Literature reviews support continuing anticoagulation during dental procedures. However, studies often present grouped anticoagulation data, and information on individual anticoagulant management would be helpful to dentists. The Edoxaban Management in Diagnostic and Therapeutic Procedures (EMIT-AF/VTE) programme (NCT02950168; NCT02951039) demonstrated low periprocedural bleeding and thrombotic event rates in patients with atrial fibrillation receiving edoxaban.

Aims: Cardiac device-related infective endocarditis (CDRIE) is a severe complication of cardiac device (CD) implantation and is usually treated by antibiotic therapy and percutaneous device extraction. Few studies report the management and prognosis of CDRIE in real life. In particular, the rate of device extraction in clinical practice and the management of patients with left heart infective endocarditis (LHIE) and an apparently non-infected CD (LHIE+CDRIE-) are not well described.

Estimating the speed of sound for the dense vapor phase of D (dodecamethylcyclohexasiloxane, CHOSi) is particularly relevant to the study of nonideal compressible fluid dynamics (NICFD), the gas dynamics of fluids whose properties depart significantly from those related by the ideal gas model. If molecular complexity is sufficiently large, dense vapor flows may exhibit so-called nonclassical gasdynamic effects, and D is a candidate for experimental studies aimed at proving for the first time the existence of these exotic phenomena. More in general, speed of sound measurements in the dense vapor phase are important for NICFD applications: for example, complex organic compounds are employed as working fluids in organic Rankine cycle power plants and the correct prediction of the dense-vapor speed of sound is of paramount importance for the design of the supersonic turbines equipping these systems.

Membranous ventricular septal aneurysm (VSA) is an uncommon cardiac abnormality, potentially leading to several cardiac complications such as aortic valve prolapse, arrhythmias, and aneurysm rupture. A young competitive soccer player presented for a post-COVID sports cardiology assessment, denying any previous cardiological evaluations. On transthoracic echocardiography, a membranous VSA was incidentally found with no other cardiac abnormality nor hemodynamic impairment associated.

Article Synopsis
  • The study aimed to compare clinical features and outcomes between culture-positive infective endocarditis (CPIE) and culture-negative infective endocarditis (CNIE) patients, noting that CNIE has a higher mortality rate.
  • Researchers analyzed data from 3,113 patients, finding 83.2% had CPIE and 16.8% had CNIE; one-year mortality was notably higher for CNIE patients receiving only medical therapy.
  • The findings suggest that while patients with CNIE have poorer long-term outcomes, those who undergo surgery benefit from reduced mortality rates, highlighting the need for improved diagnosis and early identification of CNIE cases.

Inadvertent placement of pacemaker and implantable cardioverter-defibrillator (ICD) leads in the left ventricle is a rare but well-recognized complication of device implantation. We report a case of an unicameral ICD lead inadvertently placed through the left subclavian artery right positioned, across the aortic valve into the left ventricle, in a patient with situs viscerum inversus. A transthoracic echocardiogram about a month after the procedure showed an unusual course of the lead.
