It is also innovative as it combines minimally invasive techniques with advanced surgical precision, offering better cosmetic results and expanding surgical options for complex congenital heart defects. This study aimed to evaluate the clinical outcomes of right subaxillary mini-incision procedures for TOF transatrial repair with pulmonary valve preservation.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Methods: &lt;/strong&gt;The cases of 20 pediatric patients diagnosed with TOF who underwent right subaxillary mini-incision transatrial repair with pulmonary valve preservation at the Sixth Medical Center of the Chinese People's Liberation Army General Hospital from August 2020 to February 2022 were reviewed.

The primary outcome measures included pressure gradients across the pulmonary valve and right ventricular outflow tract (RVOT), assessed immediately postoperatively and at 1 week, 3, 6, and 12 months. The secondary outcome measures included mortality rate and the degree of pulmonary valve regurgitation. Postoperative follow-up includes regular telephone calls and outpatient visits at 3, 6, and 12 months thereafter to monitor cardiac function, pulmonary valve performance, and overall recovery.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;All 20 patients survived the procedure and were discharged uneventfully, with no severe complications during hospitalization. Median cardiopulmonary bypass (CPB) time is 139 minutes (range, 77-334 minutes), and median aortic clamp time is 105 minutes (range, 44-242 minutes). The significant decreases were observed postoperatively in mean pressure gradients across the RVOT (6.1±3.2 &lt;i&gt;vs.&lt;/i&gt; 45.6±33.4 mmHg, P&lt;0.05) and the pulmonary valve (19.0±12.3 &lt;i&gt;vs.&lt;/i&gt; 59.4±27.7 mmHg, P&lt;0.05).

Two reviewers independently screened studies, extracted data, and assessed methodological quality using the National Institutes of Health (NIH) tool. Evidence quality was further evaluated with the Confidence in Network Meta-Analysis (CINeMA) framework. A Bayesian network meta-analysis (BNMA) in R (version 4.3.3) synthesized direct and indirect evidence, estimating relative risks (RRs) with 95% credible intervals (CrIs) and ranking tip locations via surface under the cumulative ranking curve (SUCRA).

The results demonstrated that positioning the catheter tip in the SV was the most effective in reducing the risk of complications. Compared with the distal axillary vein (AV), the SV was associated with a statistically significant reduction in the risk of catheter-related thrombosis (CRT) (RR =0.36; 95% CrI: 0.13-0.92), catheter occlusion (RR =0.12; 95% CrI: 0.05-0.27), and phlebitis (RR =0.31; 95% CrI: 0.09-0.94).

Traditional mechanistic explanations cannot account for all cases, and autoimmune antibodies have emerged as a novel pathogenic factor. This review summarizes the associations between autoimmune antibodies and arrhythmias, outlining the molecular mechanisms by which these antibodies interfere with cardiac ion channels, receptors, and cellular structures, and providing new insights into the diagnosis and treatment of AD-related arrhythmias.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Methods: &lt;/strong&gt;Recent studies on autoimmune antibodies and atrial/ventricular arrhythmias or cardiac conduction system damage were retrieved from academic databases (PubMed, Embase, Cochrane Library, and Web of Science), particularly those focusing on antibody types, target sites, and electrophysiological changes.

Anti-Kir3.4 antibodies shorten the atrial effective refractory period (AERP) by binding to the channel's extracellular domain, increasing susceptibility to AF by 2.8-fold. Anti-β1-R and anti-M2-R antibodies promote atrial fibrosis, elevating the risk of AF. (II) In cardiac conduction system damage, anti-Ro/Sjögren's syndrome A (SSA) antibodies cross the placenta to damage fetal cardiac conduction tissue, causing congenital heart block (CHB) with a recurrence risk of 12-25%. In adults, the presence of anti-Ro/SSA antibodies is associated with atrioventricular block (AVB) and prolonged QT interval, possibly via inhibition of L-type calcium channels (LCCs). (III) In ventricular arrhythmias, anti-β1-R antibodies enhance LCCs and reduce potassium currents (IK1 and Ito), prolonging the QT interval and inducing ventricular tachycardia (VT). These antibodies are independent risk factors in dilated cardiomyopathy (DCM). Anti-calcium channel antibodies interfere with LCCs, promoting VT and sudden cardiac death (SCD), particularly in patients without structural heart disease.

This approach involves accessing the distal radial artery (DRart) in the anatomical snuffbox, offering an alternative to traditional radial and femoral access, with demonstrated benefits over conventional transradial access (TRA), such as a lower rate of radial artery occlusion, shorter hemostasis time, and improved patient comfort. DRA is technically more demanding compared to TRA. The smaller size of the DRart and the anatomical landmarks that surround it make it more difficult to cannulate, especially for operators who are less experienced with the approach. This increased difficulty can result in higher initial failure rates and longer procedural times, all of which contribute to a steeper learning curve. This review aims to provide a comprehensive guide to the use of DRA for the interventional cardiologist to take full advantage of the approach by summarizing current evidence and experienced operator recommendations, focusing on practical recommendations on techniques to improve procedural success, minimize complications, and optimize results.</p>","PeriodicalId":9592,"journal":{"name":"Cardiovascular diagnosis and therapy","volume":"15 3","pages":"665-683"},"PeriodicalIF":2.1,"publicationDate":"2025-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12246993/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144625430","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

SCAD is a rare cause of ACS that can lead to myocardial injury due to SCAD. This review evaluates optimal antiplatelet therapy for SCAD patients. There is no clear consensus regarding the optimum antiplatelet medication regimen and treatment duration for SCAD despite current American Heart Association (AHA) consensus guidelines recommending 12-month regimen of dual antiplatelet therapy (DAPT) consisting of a P2Y12 inhibitor and aspirin for patients following myocardial infarction (MI). The objective of this study was to evaluate the safety and effectiveness of DAPT compared to using a single antiplatelet therapy (SAPT) as part of the medical armamentarium to treat SCAD.</p><p><strong>Methods: </strong>This review included only observational studies published in English and excluded randomized controlled trials. A comprehensive search of PubMed, Ovid, and SCOPUS was conducted to identify studies that examined SCAD outcomes including mortality, recurrence, and major adverse cardiovascular events (MACEs) between 2000-2023 after antiplatelet therapy was administered. Based on the documentation in various studies, only 17 relevant studies were identified in which SAPT (primarily aspirin) and DAPT (aspirin combined with a P2Y₁₂ inhibitor) were administered. SCAD for SAPT and DAPT groups were analyzed by calculating the mean, standard deviation (SD), range, and 95% confidence intervals (CIs). Results were reported as mean ± SD, with CIs indicating precision. Studies lacking comprehensive data on concurrent cardiovascular medication use (e.g., beta-blockers, statins) or key outcome measures were excluded.</p><p><strong>Results: </strong>DAPT treatment was associated with a worse prognosis than SAPT 12 months after patients presented with SCAD. A key observation was the prevalence of antiplatelet treatment in SCAD patients, with DAPT prescribed in the majority of cases. DAPT demonstrated significantly higher rates of mortality (4.96% <i>vs.</i> 1.55%), MACE (12.13% <i>vs.</i> 6.91%), and hospitalizations for angina (23.75% <i>vs.</i> 2.60%) compared to SAPT. SCAD recurrence was also more frequent in the DAPT group (5.54% <i>vs.</i> 2.33%). These adverse outcomes, primarily driven by increased non-fatal MI and unplanned percutaneous coronary interventions (PCIs), highlight the challenges of DAPT in SCAD management.</p><p><strong>Conclusions: </strong>In patients treated with antiplatelet therapy, adverse events that include unstable angina, mortality, and repeat revascularization were greater in patients with more aggressive antiplatelet therapy consisting for safety and efficacy of DAPT compared with these treated with SAPT.</p>","PeriodicalId":9592,"journal":{"name":"Cardiovascular diagnosis and therapy","volume":"15 3","pages":"705-713"},"PeriodicalIF":2.1,"publicationDate":"2025-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12246987/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144625432","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
