INTRODUCTION: This meta-analysis was to evaluate the efficacy and safety of radiofrequency catheter ablation (RFCA) in treating children with paroxysmal supraventricular tachycardia (PSVT). METHODS: From inception to December 16, 2023, PubMed, Embase, Cochrane Library, Web of Science, CNKI (China National Knowledge Infrastructure), VIP (Chinese Science and Technology Periodical Database), and WanFang were searched for this meta-analysis. Children under the age of 18, diagnosed with atrioventricular reentrant tachycardia (AVRT) and atrioventricular nodal reentrant tachycardia (AVNRT) were enrolled...

BACKGROUND: Floppy mitral valve/mitral valve prolapse (FMV/MVP) is a complex entity in which several clinical manifestations are not directly related to the severity of mitral regurgitation (MR). SUMMARY: Patients with FMV/MVP and trivial to mild MR may have exercise intolerance, orthostatic phenomena, syncope/presyncope, chest pain, and ventricular arrhythmias, among others. Several anatomical and pathophysiologic consequences related to the abnormal mitral valve apparatus and to prolapse of the mitral leaflets into the left atrium provide some explanation for these symptoms...

INTRODUCTION: The exercise-based cardiac rehabilitation program (CRP) represent a multidisciplinary therapeutic approach tailored to improving cardiorespiratory fitness and overall health-related quality of life, while reducing cardiovascular hospitalizations and mortality. Our aim is to determine changes in exercise capacity and cardiac events according to the left ventricular ejection fraction (LVEF) following a CRP. METHODS: This single-center cohort study of 131 patients who completed a center-based CRP from 2015 to 2022...

BACKGROUND: Thromboembolic events (TE) associated with left ventricular (LV) thrombus (LVT) are of clinical concern; however, further investigation into their prevalence and risk predictors is warranted. METHODS: We retrospectively identified 256 patients diagnosed with LVT by echocardiography between 2010 and 2021. The primary outcome was the occurrence of TE, including stroke and arterial thromboembolism. Patients were divided into TE (+) and TE (-) groups for clinical comparison, with a focus on factors related to TE...

UNLABELLED: Introduction Heart Failure (HF) may induce bowel hypoperfusion, leading to hypoxia of the villa of the bowel wall and the occurrence of Clostridioides difficile infection (CDI). However, the risk factors for the development of CDI in HF patients have yet to be fully illustrated, especially because of a lack of evidence from real-world data. METHODS: Clinical data and survival situations of HF patients with CDI admitted to ICU were extracted from the Medical Information Mart for Intensive Care (MIMIC)-IV database...

INTRODUCTION: People with HIV (PWH) have increased risk of atherosclerotic cardiovascular disease (ASCVD) compared to non-PWH, but the reasons for this increased risk remain elusive. We investigated the change in ASCVD risk scores over 4-years to identify clinical factors associated with change in risk scores or high risk scores. METHODS: We conducted a preliminary study using retrospective analysis of PWH, between 40-75 years old, seen at the Evelyn Jordan Center with at least two routine HIV visits...

Introduction Automatic Implantable Cardioverter-Defibrillators (AICD) for the primary prevention of sudden cardiac death (SCD) have become standard care for patients with systolic heart failure (sHF) and ejection fraction < 35%. While the prevalence of sHF and rates of hospitalization are higher in men; one would expect equivalent rates of implantation in women. Methods We used the Healthcare Cost and Utilization Project's National Inpatient Sample (NIS) from 2009-2018 to identify patient visits with sHF and AICD implantation...

INTRODUCTION: To explore the cytological characteristics of tetralogy of Fallot (TOF), we collected samples and studied the differences in cytological classification between normal fetal hearts and fetuses with TOF, and then we searched for possible differential genes of disease markers through single-cell sequencing analysis. METHODS: In this study, we analyzed the right ventricle of a TOF and a healthy human fetal heart sample by single-cell sequencing. Utilizing Cellranger to perform data quality control filtering, comparison, quantification, and identification of recovered cells on the raw data, ultimately obtaining gene expression matrices for each cell...

INTRODUCTION: Muscular ventricular septal defect occluders (MVSDO) have been attempted as an option in low-weight patients with patent ductus arteriosus (PDA). Few studies have assessed the safety of transcatheter patent ductus arteriosus closure (TCPC) using MVSDO. Therefore, we compared the outcomes in low-weight patients who used MVSDO and mushroom-shaped occluder (MSO). METHODS: Medical records of children under 10 kg (n=417) who underwent TCPC from 2015 to 2021 at a Chinese health center were reviewed...

INTRODUCTION: To analyze the blood transfusion factors of minimally invasive direct coronary artery bypass (MIDCAB) surgery using artificial intelligence. METHODS: A retrospective analysis was performed for patients undergoing MIDCAB operations that no heart-lung machine was used from January 2017 to September 2022 in our hospital. The influencing factors of blood transfusion were used to build the artificial intelligence model. Eighty percent of the database was used as the training set, and twenty percent database was used as the testing set...

INTRODUCTION: Heart Failure with Improved Ejection Fraction (HFimpEF) is a recently defined subtype of HF, characterized by an increase in ejection fraction (EF) after a prior diagnosis of reduced EF. There is limited data on the characteristics and outcome of this patient subset. The study aimed to investigate the clinical profile and prognosis of this patient group. METHODS: HFimpEF patients from a large echocardiography database with comprehensive clinical and outcome data were evaluated for clinical characteristics and outcomes including mortality and cardiovascular hospitalizations...

Introduction There has been remarkable progress in both diagnosis and treatment of patients with congenital heart disease (CHD), with an increasing number of survivors. Whether patients with CHD are more likely to develop cancer is still a controversial issue. This study aimed to quantitatively estimate the association between patients with CHD and the risk of developing cancer through meta-analysis. Methods Web of Science, PubMed, and Embase databases were searched from inception to September 2023 to identify potentially relevant case-control studies and cohort studies that reported risk estimates and confidence intervals...

BACKGROUND: Atrial fibrillation (AF) is a common arrhythmia, with radiofrequency catheter ablation (RFCA) being first-line therapy. However, the high rate of post-ablation recurrence necessitates the identification of predictors for recurrence risk. Left atrial low-voltage areas (LA-LVASs), reflecting atrial fibrosis, have been confirmed to be related to recurrence of atrial fibrillation. Recently, epicardial adipose tissue (EAT) has been studied due to its role in initiating and maintaining atrial fibrillation...

INTRODUCTION: Heart failure is a common chronic illness associated with high readmission rates and death. Comprehensive nursing care, management of symptoms, and psychological support are increasingly seen as critical components of successful heart failure therapy. OBJECTIVE: This systematic review and meta-analysis aimed to determine the effect of comprehensive nursing care on clinical outcomes and quality of life in heart failure patients. METHODS: We searched electronic databases (Pubmed, PROSPERO, and Web of Science) for randomised controlled trials and observational studies on comprehensive nursing care treatments for heart failure patients...

INTRODUCTION: Angiotensin-converting enzyme 2 (ACE2) of the renin-angiotensin-aldosterone system (RAAS) serves as a functional receptor to gain entry into the cells for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which causes coronavirus disease 2019 (COVID-19). The interaction between SARS-CoV-2 and ACE2 is a potential virulent factor in infectivity. Our study aims to ascertain the association of RAAS inhibitors with adverse cardiovascular and other outcomes in hospitalized COVID-19 patients...
