Short-duration head-up tilt test potentiated with sublingual nitroglycerin in suspected vasovagal syncope: the fast Italian protocol.

Background: The traditional nitroglycerin (NTG) head-up tilt test (HUTT) is time-consuming and the test duration is a barrier to widespread utilization in clinical practice. It was hypothesized that a short-duration protocol is not inferior to the traditional protocol regarding the positivity rate and has a similar distribution of hemodynamic response.

Methods And Results: Patients undergoing HUTT were randomized 1:1 to a 10 min passive phase plus a 10 min 0.

Outcomes of transvenous lead extraction of very old leads using bidirectional rotational mechanical sheaths: Results of a multicentre study.

Introduction: Lead dwell time >10 years is a recognized predictor for transvenous lead extraction (TLE) failure and complications. Data on the efficacy and safety of TLE using the bidirectional rotational mechanical sheaths in patients with very old leads are lacking. In this multicenter study, we reported the outcomes of transvenous rotational mechanical lead extraction in patients with leads implanted for ≥10 years.

Removal of an active fixation coronary sinus pacing lead 5 years postimplant: A case report.

Active fixation for a lead in the coronary sinus may be essential to select the optimal left ventricular pacing site, maximize the effectiveness of cardiac resynchronization therapy (CRT) and avoid dislodgement. The Medtronic Attain Stability lead allows fixation through a side helix concentric with the lead body. Although electrical performance of such a lead is well known, evidence of extractability remains poor especially in the long term.

Inadvertent left ventricular placement of ICD lead through the left subclavian artery right positioned in a patient with situs viscerum inversus and Kartagener syndrome.

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.

Remote assessment of QT interval: A new perspective for implantable cardiac monitors.

Background: There is an unmet need for simple tools for monitoring QT intervals. The feasibility of measuring the QT interval on the single‑lead subcutaneous electrocardiogram (subECG) recorded and transmitted by implantable cardiac monitors (ICMs) has never been tested.

Methods: We performed a standard ECG in patients who had already been implanted with a long sensing vector ICM (BIOMONITOR, Biotronik SE&Co.

Theophylline in patients with syncope without prodrome, normal heart, and normal electrocardiogram: a propensity-score matched study verified by implantable cardiac monitor.

Aims: Syncope without prodromes in subjects with normal heart and normal electrocardiogram (ECG) is classified as non-classical neurally mediated syncope and is characterized by low adenosine plasma levels (APLs) and frequent asystolic syncope. We assessed the efficacy of theophylline, a non-selective adenosine receptor antagonist, in preventing syncopal events.

Methods And Results: Participants received an implantable cardiac monitor, underwent APL measurement, and received oral theophylline at maximum tolerated dose (starting dose 300 mg b.

The Impact of COVID-19 Outbreak on Syncope Units Activities in Italy: A Report from the Italian Multidisciplinary Working Group on Syncope (GIMSI).

The aim of our study was to evaluate the impact of the COVID-19 outbreak on Syncope Units (SUs) Activities in Italy. Data about types of SU activities and admissions were obtained from 10 SUs throughout Italy, certified by the Italian Multidisciplinary Working Group on Syncope (GIMSI), from 10 March 2020 to 31 December 2020 and compared with the same time frame in 2019. A remarkable reduction in overall non-invasive diagnostic tests (-67%; < 0.

Cardiac Involvement in COVID-19 Patients: A Contemporary Review.

: The widely variable clinical manifestations of SARS-CoV2 disease (COVID-19) range from asymptomatic infections to multiple organ failure and death. Among the organs affected is the heart. This does not only affect people who already have previous cardiovascular problems, but also healthy people.

Dalbavancin Efficacy and Impact on Hospital Length-of-Stay and Treatment Costs in Different Gram-Positive Bacterial Infections.

Background And Objectives: The study aimed to evaluate the impact of dalbavancin therapy on both hospital length-of-stay (LOS) and treatment-related costs, as well as to describe the clinical outcome, in a retrospective cohort of patients with diverse Gram-positive bacterial infections, hospitalized in different specialty Units.

Methods: From July 2017 to July 2019, clinical and sociodemographic data were collected for all hospitalized patients switched to dalbavancin for the treatment of Gram-positive infections. LOS and treatment-related costs were assessed and compared to a hypothetical scenario where the initial standard antimicrobial therapy would have been administered in hospital for the same duration as dalbavancin.

What we have learned for the future about COVID-19 and healthcare management of it?

Background And Aim Of The Work: COVID-19 is a current global pandemic. However, comprehensive global data analyses for its healthcare management are lacking.

Methods: In this study we have researched through published scientific articles and international health care  guidelines to find out actually about our knowledge for this new pandemic from SARS-CoV-2 and related COVID-19 disease that emerged from December 2019 in China in order to better manage this health emergency.

The human coronaviruses (HCoVs) and the molecular mechanisms of SARS-CoV-2 infection.

In humans, coronaviruses can cause infections of the respiratory system, with damage of varying severity depending on the virus examined: ranging from mild-to-moderate upper respiratory tract diseases, such as the common cold, pneumonia, severe acute respiratory syndrome, kidney failure, and even death. Human coronaviruses known to date, common throughout the world, are seven. The most common-and least harmful-ones were discovered in the 1960s and cause a common cold.

Usefulness of F-FDG PET/CT in Patients with Cardiac Implantable Electronic Device Suspected of Late Infection.

The presence of a cardiovascular implantable electronic device (CIED) can be burdened by complications such as late infections that are associated with significant morbidity and mortality and require immediate and effective treatment. The aim of this study was to evaluate the role of F-fluorodeoxyglucose positron-emission tomography/computed tomography (F-FDG PET/CT) in patients with suspected CIED infection. Fifteen patients who performed a F-FDG PET/CT for suspicion of CIED infection were retrospectively analyzed; 15 patients, with CIED, that underwent F-FDG PET/CT for oncological reasons, were also evaluated.

Multicenter experience with the Evolution RL mechanical sheath for lead extraction using a stepwise approach: Safety, effectiveness, and outcome.

Background: In addition to the Evolution RL sheath, tools by Cook Medical (Bloomington, IN, USA), supporting lead extraction (LE), are available. Data on their use are not reported in detail in previous studies. Moreover, data regarding outcome are lacking.

Head-to-head comparison of peak upright bicycle and post-treadmill echocardiography in detecting coronary artery disease: a randomized, single-blind crossover study.

Background: Post-treadmill digital echocardiography (post-TME) is the most widely used form of exercise echocardiography, but ischemia can rapidly resolve in the postexercise period; peak upright bicycle digital echocardiography (UBE) has the advantage of providing images at peak exercise that reflect normal physiology. However, the comparative accuracy of the two methods in detecting ischemia in the same patients is unknown. To compare the relative diagnostic value of peak UBE and post-TME in detecting coronary artery disease, both tests were performed in 86 consecutive patients undergoing coronary angiography.
