A new protocol for a single-stage combined cardiopulmonary and echocardiography exercise test: a pilot study.

Aims: The value of cardiopulmonary exercise testing (CPET) and exercise stress echocardiography (ESE) in managing cardiac disease is well known, but no standard CPET-ESE protocol is currently recommended. This pilot study aims to compare feasibility and cardiac function responses between a new high-intensity single-stage combined test (CPET-hiESE) and a standard maximal ESE (smESE).

Methods And Results: After screening and maximal CPET, all volunteers ( = 21) underwent three ESE modalities: (i) based on the gas exchange threshold (hiESE-GET, 40% of peak-GET, 6 min), (ii) based on heart rate (HR) (hiESE-HR, 80% of peak HR, 6 min), and (iii) smESE (85% of predicted peak HR for age, 3 min).

Prospective evaluation of acute neurological events after paediatric cardiac surgery.

Objectives: Children with CHD are at heightened risk of neurodevelopmental problems; however, the contribution of acute neurological events specifically linked to the perioperative period is unclear.

Aims: This secondary analysis aimed to quantify the incidence of acute neurological events in a UK paediatric cardiac surgery population, identify risk factors, and assess how acute neurological events impacted the early post-operative pathway.

Methods: Post-operative data were collected prospectively on 3090 consecutive cardiac surgeries between October 2015 and June 2017 in 5 centres.

The Role of Speckle-Tracking Echocardiography in Predicting Mortality and Morbidity in Patients With Congenital Heart Disease: A Systematic Review and Meta-analysis.

Background: Speckle-tracking echocardiography (STE) is now routinely included in cardiac evaluations, but its role in predicting mortality and morbidity in congenital heart disease (CHD) is not well described. We conducted a systematic review to evaluate the prognostic value of STE in patients with CHD.

Methods: The EMBASE, Medline, Web of Science, Scopus, and Cochrane Central Register of Controlled Trials (CENTRAL) databases were searched from inception to January 2023 for terms related to all CHD, STE, and prognosis.

Less (Transfusion) Is More-Enhancing Recovery through Implementation of Patient Blood Management in Cardiac Surgery: A Retrospective, Single-Centre Study of 1174 Patients.

The implementation of Patient Blood Management (PBM) in cardiac surgery has been shown to be effective in reducing blood transfusions and associated complications, as well as improving patient outcomes. Despite the potential benefits of PBM in cardiac surgery, there are several barriers to its successful implementation. The main objectives of this study were to ascertain the impact of the national Romanian PBM recommendations on allogeneic blood product transfusion in cardiac surgery and identify predictors of perioperative packed red blood cell transfusion.

Unprotected Left Main Bifurcation Stenting in Acute Coronary Syndromes: Two-Stent Technique versus One-Stent Technique.

Aims: There is little evidence guiding the choice between a one-stent and a two-stent approach in unprotected distal left main coronary artery disease (UDLMCAD) presenting as acute coronary syndrome (ACS). We aim to compare these two techniques in an unselected ACS group.

Methods And Results: We conducted a single center retrospective observational study, that included all patients with UDLMCAD and ACS undergoing PCI between 2014 and 2018.

The use of 2-D speckle tracking echocardiography in differentiating healthy adolescent athletes with right ventricular outflow tract dilation from patients with arrhythmogenic cardiomyopathy.

Aims: Echocardiographic assessment of adolescent athletes for arrhythmogenic cardiomyopathy (ACM) can be challenging owing to right ventricular (RV) exercise-related remodelling, particularly RV outflow tract (RVOT) dilation. The aim of this study is to evaluate the role of RV 2-D speckle tracking echocardiography (STE) in comparing healthy adolescent athletes with and without RVOT dilation to patients with ACM.

Methods And Results: A total of 391 adolescent athletes, mean age 14.

The use of 2-D speckle tracking echocardiography in assessing adolescent athletes with left ventricular hypertrabeculation meeting the criteria for left ventricular non-compaction cardiomyopathy.

Background: Current echocardiographic criteria cannot accurately differentiate exercise induced left ventricular (LV) hypertrabeculation in athletes from LV non-compaction cardiomyopathy (LVNC). This study aims to evaluate the role of speckle tracking echocardiography (STE) in characterising LV myocardial mechanics in healthy adolescent athletes with and without LVNC echocardiographic criteria.

Methods: Adolescent athletes evaluated at three sports academies between 2014 and 2019 were considered for this observational study.

Left main coronary artery compression by dilated pulmonary artery in pulmonary arterial hypertension: a systematic review and meta-analysis.

Objective: Pulmonary arterial hypertension (PAH) can lead to left main coronary artery compression (LMCo), but data on the impact, screening and treatment are limited. A meta-analysis of LMCo cases could fill the knowledge gaps in this topic.

Methods: Electronic databases were searched for all LMCo/PAH studies, abstracts and case reports including pulmonary artery (PA) size.

Investigating the Accuracy of Quantitative Echocardiographic-Modified Task Force Criteria for Arrhythmogenic Ventricular Cardiomyopathy in Adolescent Male Elite Athletes.

Athlete preparticipation screening focuses on preventing sudden cardiac death (SCD) by detecting diseases such as arrhythmogenic ventricular cardiomyopathy (AVC), which affects primarily the right ventricular myocardium. Diagnosis may be obscured by physiological remodeling of the athlete heart. Healthy athletes may meet the 2010 Task Force Criteria right ventricular outflow tract (RVOT) dimension cut-offs, questioning the suitability of the modified Task Force Criteria (mTFC) in adolescent athletes.

Exercise training in paediatric congenital heart disease: fit for purpose?

Exercise and physical activity (PA) have been shown to be effective, safe and feasible in both healthy children and children with congenital heart disease (CHD). However, implementing exercise training as an intervention is still not routine in children with CHD despite considerable evidence of health benefits and well-being. Understanding how children with CHD can safely participate in exercise can boost participation in PA and subsequently reduce inactivity-related diseases.

The Role of Speckle Tracking Echocardiography in the Evaluation of Common Inherited Cardiomyopathies in Children and Adolescents: A Systematic Review.

Speckle tracking echocardiography (STE) has gained importance in the evaluation of adult inherited cardiomyopathies, but its utility in children is not well characterized. We conducted a systematic review to evaluate the role of STE in pediatric inherited cardiomyopathies. PubMed, EMBASE, Web of Science, Scopus, CENTRAL and CINAHL databases were searched up to May 2020, for terms related to inherited cardiomyopathies and STE.

Four-year outcomes after percutaneous coronary intervention of unprotected left main coronary artery disease in patients with stable angina and acute coronary syndrome.

Percutaneous coronary intervention (PCI) of unprotected left main coronary artery disease (ULMCAD) have become a feasible and efficient alternative to coronary artery bypass surgery, especially in patients with acute coronary syndrome (ACS). There are limited data regarding early and late outcomes after ULMCAD PCI in patients with ACS and stable angina.The aim of this study was to compare early and four-year clinical outcomes in patients with ULMCAD PCI presenting as ACS or stable angina in a high-volume PCI center.

Factors associated with unplanned reinterventions and their relation to early mortality after pediatric cardiac surgery.

Objective: Unplanned reintervention (uRE) is used as an indicator of patient morbidity and quality of care in pediatric cardiac surgery. We investigated associated factors and early mortality after uREs.

Methods: Morbidity data were prospectively collected in 5 UK centers between 2015 and 2017; uRE included surgical cardiac, interventional transcatheter cardiac, permanent pacemaker, and diaphragm plication procedures.

Outcomes following aortic valve procedures in 201 complex congenital heart disease cases-results from the UK National Audit.

Objectives: Some patients with complex congenital heart disease (cCHD) also require aortic valve (AoV) procedures. These cases are considered high risk but their outcome has not been well characterized. We aim to describe these scenarios in the current practice, and provide outcome data for counselling and decision-making.

Does routine fenestration improve early and late postoperative outcomes in patients undergoing Fontan palliation?

A best evidence topic in cardiac surgery was written according to a structured protocol. The question addressed was: 'In [patients undergoing Fontan palliation] does [fenestration] affect [early and late postoperative outcomes]?' Altogether 509 papers were found using the reported search, of which 11 papers represented the best evidence to answer the clinical question. The authors, journal, date and country of publication, patient group studied, study type, relevant outcomes and results of these papers are tabulated.

Age over 35 years is associated with increased mortality after pulmonary valve replacement in repaired tetralogy of Fallot: results from the UK National Congenital Heart Disease Audit database.

Objectives: Many adults with repaired tetralogy of Fallot will require a pulmonary valve replacement (PVR), but there is no consensus on the best timing. In this study, we aim to evaluate the impact of age at PVR on outcomes.

Methods: This is a national multicentre retrospective study including all patients >15 years of age with repaired tetralogy of Fallot who underwent their first PVR between 2000 and 2013.

Cardiotoxicity evaluation in pediatric patients with acute lymphoblastic leukemia - results of prospective study.

Aim: The chemotherapy protocol for acute lymphoblastic leukemia (ALL) uses low doses of anthracyclines (AC), generally associated with subclinical cardiotoxicity. The aim of our study was to evaluate the serum biomarkers and echocardiography parameters in children with ALL treated with AC in order to determine the most useful element for early detection of cardiotoxicity.

Material And Methods: In this prospective study, troponin I (TnI) and heart-type fatty acid binding protein (HFABP) were assessed five times during the first year after the onset of ALL.

Clinical and cost-effectiveness of the Ross procedure versus conventional aortic valve replacement in young adults.

Objectives: In young and middle-aged adults, there are three current options for aortic valve replacement (AVR), namely mechanical AVR (mechAVR), tissue AVR (biological AVR) and the Ross operation, with no clear guidance on the best option. We aim to compare the clinical effectiveness and cost-effectiveness of the Ross procedure with conventional AVR in young and middle-aged adults.

Methods: This is a systematic literature review and meta-analysis of AVR options.

Surgical Repair of Tetralogy of Fallot With Absent Pulmonary Valve: Favorable Long-Term Results.

Tetralogy of Fallot with absent pulmonary valve syndrome (ToF-APVS) is a rare variant of tetralogy, associated with severe pulmonary valve regurgitation and aneurysmal dilation of the pulmonary arteries (PAs). Reported outcomes after surgical corrections are limited to single center, older series and might not reflect the current outcome. We aim to use data from a national registry to evaluate short- and long-term outcomes after surgical repair of ToF-APVS, to serve for counselling and planning.

MicroRNAs as potential biomarkers in congenital heart surgery.

Objective: Pediatric congenital heart surgery (CHS) involves intracardiac, valvular, and vascular repairs. Accurate tools to aid short-term outcome prediction in pediatric CHS are lacking. Clinical scores, such as the vasoactive-inotrope score and ventilation index, are used to define outcome in clinical studies.

Surgical versus balloon valvotomy in neonates and infants: results from the UK National Audit.

Objective: There are conflicting data on choosing balloon aortic valvoplasty (BAV) or surgical aortic valvotomy (SAV) in neonates and infants requiring intervention for aortic valve stenosis. We aim to report the outcome of both techniques based on results from the UK national registry.

Methods: This is a retrospective study, including all patients under 1 year undergoing BAV/SAV between 2000 and 2012.

Primary repair versus surgical and transcatheter palliation in infants with tetralogy of Fallot.

Objectives: Treatment of infants with tetralogy of Fallot (ToF) has evolved in the last two decades with increasing use of primary surgical repair (PrR) and transcatheter right ventricular outflow tract palliation (RVOTd), and fewer systemic-to-pulmonary shunts (SPS). We aim to report contemporary results using these treatment options in a comparative study.

Methods: This a retrospective study using data from the UK National Congenital Heart Disease Audit.
