Background: Following the publication of international cardio-oncology (CO) imaging guidelines, standard echocardiographic monitoring parameters of left ventricular systolic function have been endorsed. Recommendations highlight that either two-dimensional (2D) or three-dimensional (3D) left ventricular ejection fraction (LVEF), alongside global longitudinal strain (GLS) should be routinely performed for surveillance of patients at risk of cancer therapy-related cardiac dysfunction (CTRCD). We studied the feasibility of 3D-LVEF, 2D-GLS and 2D-LVEF in a dedicated CO service.

Objectives: This trial aimed to compare conventional and haemostatic dressings in achieving rapid and effective radial artery haemostasis following coronary procedures.

Background: In small studies, using a haemostatic dressing is associated with expedited haemostasis and a reduced duration of external radial compression.

Methods: Patients were randomised to one of three compression strategies: 120-min (min) with conventional dressing (C2) vs 60-min with conventional dressing (C1) vs 60-min with haemostatic dressing (H1).

Article Synopsis
  • - The BRIGHT-4 study showed that using bivalirudin with a high-dose infusion after PCI led to lower overall mortality and bleeding risks compared to heparin, without raising rates of reinfarction or stent thrombosis in STEMI patients.
  • - A meta-analysis of six trials involving over 15,000 patients found that while bivalirudin reduced overall and cardiac mortality and major bleeding, it was associated with higher rates of reinfarction and stent thrombosis compared to heparin.
  • - When specifically looking at a subset of trials similar to the BRIGHT-4 approach, bivalirudin also showed a decrease in 30-day mortality and major bleeding, with comparable rates of reinfar

Introduction: Percutaneous coronary intervention for complex coronary disease is associated with a high risk of cardiogenic shock. This can cause harm and limit the quality of revascularization achieved, especially when left ventricular function is impaired at the outset. Elective percutaneous left ventricular unloading is increasingly used to mitigate adverse events in patients undergoing high-risk percutaneous coronary intervention, but this strategy has fiscal and clinical costs and is not supported by robust evidence.

Hypertrophic cardiomyopathy is a common inherited cardiac condition where the myocardium progressively thickens in the absence of abnormal loading conditions. Left ventricular hypertrophy often leads to outflow tract obstruction, and this confers significant mortality and morbidity implications. Septal reduction therapies aim to relieve the obstruction in an attempt to reduce the burden of symptoms and potentially improve prognosis.

Obstructive hypertrophic cardiomyopathy is the most common genetically transmitted cardiomyopathy that is associated with significant morbidity and mortality. Despite contemporary treatments and interventions, the management of patients with obstructive hypertrophic cardiomyopathy remains poorly defined compared with other branches of cardiology. In this review, we discuss established and novel therapeutic interventions in patients with obstructive hypertrophic cardiomyopathy with a focus on percutaneous and surgical strategies including surgical myectomy, mitral valve repair or replacement, percutaneous alcohol septal ablation, pacemaker and cardioverter-defibrillator implantation, septal embolization, radiofrequency endocardial catheter ablation, and percutaneous intramyocardial septal radiofrequency ablation.

This study aimed to test the hypothesis that the total daily energy expenditure (TDEE) of male academy soccer players is greater than players not enrolled on a formalised academy programme. English Premier League academy (ACAD:  = 8, 13 years, 50 ± 6 kg, 88 ± 3% predicted adult stature, PAS) and non-academy players (NON-ACAD:  = 6, 13 years, 53 ± 12 kg, 89 ± 3% PAS) were assessed for TDEE (via doubly labelled water) during a 14-day in-season period. External loading was evaluated during training (ACAD: 8 sessions, NON-ACAD: 2 sessions) and games (2 games for both ACAD and NON-ACAD) via GPS, and daily physical activity was evaluated using triaxial accelerometry.

Article Synopsis
  • The study aims to compare the effectiveness and safety of bivalirudin versus heparin in patients with non-ST-segment-elevation myocardial infarction (NSTEMI) undergoing percutaneous coronary intervention (PCI), as previous analyses lacked detailed data.
  • An individual patient data meta-analysis included over 12,000 patients from five major trials, focusing on outcomes like 30-day all-cause mortality and serious bleeding.
  • Results indicated no significant difference in 30-day mortality rates, cardiac mortality, reinfarction, or stent thrombosis between bivalirudin and heparin in this patient population.

Background: The current ACC/AHA guidelines on hypertrophic cardiomyopathy (HCM) caution that alcohol septal ablation (ASA) might be less effective in patients with left ventricular outflow tract obstruction (LVOTO) ≥ 100 mm Hg.

Methods: We used a multinational registry to evaluate the outcome of ASA patients according to baseline LVOTO.

Results: A total of 1346 ASA patients were enrolled and followed for 5.

Transcatheter aortic valve implantation (TAVI) is an established treatment for aortic stenosis. Cerebral embolic protection (CEP) devices may impact periprocedural stroke by capturing debris destined for the brain. However, there is a lack of high-quality randomised trial evidence supporting the use of CEP during TAVI.

Article Synopsis
  • Atrioventricular block is a common complication following alcohol septal ablation (ASA) in patients with hypertrophic obstructive cardiomyopathy, leading to some requiring a permanent pacemaker (PPM).
  • In a study involving 1,814 patients using the Euro-ASA registry, 9.4% underwent PPM implantation within 30 days after the procedure, with a follow-up averaging 4 years.
  • Long-term outcomes revealed that while survival and functional class were similar between groups, those with PPM had a lower left ventricular outflow gradient and lower likelihood of needing further interventions.

Article Synopsis
  • A new risk score called ASA-SCARRE was developed to assess the risk of sudden cardiac arrest in patients with hypertrophic obstructive cardiomyopathy after alcohol septal ablation.
  • The study analyzed over 1,800 patients and found that independent predictors of sudden cardiac arrest included septum thickness and left ventricular outflow tract gradient.
  • The ASA-SCARRE scores ranged from 0 to 2 based on these two factors, providing a simple method to predict long-term risk of cardiac events post-treatment.

Background: Measurement of fractional flow reserve (FFR) has an established role in guiding percutaneous coronary intervention. We tested the hypothesis that, at the stage of diagnostic invasive coronary angiography, systematic FFR-guided assessment of coronary artery disease would be superior, in terms of resource use and quality of life, to assessment by angiography alone.

Methods: We performed an open-label, randomized, controlled trial in 17 UK centers, recruiting 1100 patients undergoing invasive coronary angiography for the investigation of stable angina or non-ST-segment-elevation myocardial infarction.

This case highlights 2 important issues: the immediate management of large intracoronary thrombus in the ST-segment elevation myocardial infarction setting with TIMI 3 flow, and the risks/benefits associated with sealing a plaque in an unobstructed artery by stenting. Potent antithrombotic therapy with a view to subsequent intracoronary imaging to define etiology and plaque morphology appears to be a reasonable initial strategy in this specific population. Furthermore, for patients with acute coronary syndromes diagnosed with plaque erosion by optical coherence tomography and residual diameter stenosis <70%, deferred stenting appears a viable option.

Background: The aim of this study was to evaluate short- and long-term outcomes related to dose of alcohol administered during alcohol septal ablation (ASA) in patients with hypertrophic obstructive cardiomyopathy (HOCM). Current guidelines recommend using 1-3 mL of alcohol administered in the target septal perforator artery, but this recommendation is based more on practical experience of interventionalists rather than on systematic evidence.

Methods: We included 1448 patients and used propensity score to match patients who received a low-dose (1.

The remote food photography method, often referred to as "Snap-N-Send" by sport nutritionists, has been reported as a valid method to assess energy intake in athletic populations. However, preliminary studies were not conducted in true free-living conditions, and dietary assessment was performed by one researcher only. The authors, therefore, assessed the validity of Snap-N-Send to assess the energy and macronutrient composition in experienced (EXP, n = 23) and inexperienced (INEXP, n = 25) sport nutritionists.

Background:  Individual randomized controlled trials (RCTs) of periprocedural anticoagulation with bivalirudin versus heparin during percutaneous coronary intervention (PCI) have reported conflicting results. Study-level meta-analyses lack granularity to adjust for confounders, explore heterogeneity, or identify subgroups that may particularly benefit or be harmed.

Objective:  To overcome these limitations, we sought to develop an individual patient-data pooled database of RCTs comparing bivalirudin versus heparin.
