ABSTRACT
BACKGROUND: Blunt thoracic aortic injury (BTAI) represents one of the most devastating scenarios of vascular trauma. Different management strategies are available with varying clinical outcomes. However, thoracic endovascular aortic repair (TEVAR) has become the first-line option for most BTAI patients, mainly owing to its minimally invasive nature, yielding improved immediate results. This meta-analysis aims to investigate mortality, long-term survival, and reintervention following TEVAR in BTAI. MATERIAL AND METHODS: A systematic review conducted a comprehensive literature search on multiple electronic databases using strict search terms. Twenty-seven studies met the set inclusion/exclusion criteria. A proportional meta-analysis of extracted data was conducted using the Comprehensive Meta-Analysis Software, v.4. RESULTS: 1498 BTAI patients who underwent TEVAR were included. Using the SVS grading system, 2.6% of the population had Grade 1 injuries, 13.6% Grade 2, 62.2% Grade 3, 19.6% Grade 4, and 1.9% unspecific. All-cause mortality did not exceed 20% in all studies except one outlier with a 37% mortality rate. Using the random effects model, the pooled estimate of overall mortality was 12% (95% confidence interval [CI], 5.35-8.55%; I2 = 70.6%). This was 91% (95% CI, 88.6-93.2; I2 = 30.2%) at 6 months, 90.1% (95% CI, 86.7-92.3; I2 = 53.6%) at 1 year, 89.2% (95% CI, 85.2-91.8; I2 = 62.3%) at 2 years, and 88.1% (95% CI, 83.3-90.9; I2 = 69.6%) at 5 years. Moreover, the pooled estimate of reintervention was 6.4% (95% CI, 0.1-0.49%; I2 = 81.7%). CONCLUSIONS: Despite the high morbidity and mortality associated with BTAI, TEVAR has proven to be a safe and effective management strategy with favorable long-term survival and minimal need for reintervention. Nevertheless, diagnosis of BTAI requires a high index of suspicion with appropriate grading and prompt transfer to trauma centers with appropriate TEVAR facilities.
ABSTRACT
Introduction: Acute coronary syndrome (ACS) in young individuals (≤45 years) is increasingly recognized as a significant health concern, yet research in this demographic remains limited, particularly within the Palestinian context. This study aims to bridge this gap by comprehensively investigating the clinical characteristics, age-specific profiles, gender disparities, treatment modalities, and angiographic patterns of ACS in young patients compared to their older counterparts. Materials and methods: A multi-centre observational study was conducted, enroling 468 participants aged 18-55 diagnosed with ACS and admitted to three prominent Palestinian hospitals. Data were collected from medical records, and statistical analysis was performed to assess demographic characteristics, clinical presentations, risk factors, treatment strategies, and outcomes. Results: The majority of participants were male (87%), with a higher proportion in the older age group (>45 years). Clinical presentations varied, with non-ST segment elevation myocardial infarction (NSTEMI) being the most common diagnosis (48%). Risk factors such as smoking, hypertension, and diabetes were prevalent, with notable gender and age-specific differences. Percutaneous coronary intervention (PCI) was the predominant treatment strategy (83%), with consistent medication use across age groups. Conclusion: ACS in young patients poses a significant public health challenge in Palestine, necessitating tailored preventive strategies and comprehensive management approaches. Understanding the unique demographic and clinical characteristics of young ACS patients is crucial for informing targeted interventions and policies aimed at reducing the burden of cardiovascular disease in this population. These findings contribute valuable insights to the existing literature and underscore the importance of further research in this area to improve outcomes and mitigate the impact of ACS in young individuals globally.

ABSTRACT
BACKGROUND: Women undergoing cardiac surgery have been historically recognized to carry higher periprocedural mortality risk. We aimed to investigate the influence of sex on clinical presentation, perioperative, and long-term outcomes in patients who undergo surgery for ascending aortic aneurysm. METHODS: We conducted a retrospective review of 1148 consecutive patients (380 [33.1%] female) who underwent thoracic aortic surgery under moderate hypothermic circulatory arrest for ascending aortic aneurysms between 2001 and 2021. Baseline and operative characteristics, in-hospital mortality, and survival were compared between male and female patients before and after propensity-score-matched (PSM) analysis. RESULTS: Women were significantly older (median age: 69 [IQR: 63-75] vs. 67 [IQR: 58-73]; P < 0.001), while men had a higher prevalence of aortic valve stenosis, bicuspid valve and coronary artery disease at the time of surgery (P < 0.05). After PSM, EuroSCORE II (4.36 [2.68; 6.87] vs. 3.22 [1.85; 5.31]; p < 0.001), and indexed aortic diameter were significantly higher in female patients (2.94 [2.68; 3.30] vs. 2.58 [2.38; 2.81] cm/m2, p < 0.001). In the matched cohort, men were more likely to experience postoperative delirium (18.1% vs. 11.5%; P = 0.002), and postoperative neurological deficits (6.7% vs. 3.0%, P = 0.044),. Female patients were more likely to receive postoperative packed red blood cells (p = 0.036) and fresh frozen plasma (p = 0.049). In-hospital and 30-day mortality was similar between both groups. Long-term survival was comparable between both groups with 88% vs. 88% at 5 years, 76% vs. 71% at 10 years, and 59% vs. 47% at 15 years. CONCLUSION: Female patients required more transfusions, while males had a higher incidence of postoperative delirium and neurological deficits. Differences in preoperative age and timing of surgery between the sexes could be attributed to variations in comorbidity profiles and the greater prevalence of concomitant surgery indications in males.

Multiple arterial conduit revascularization in coronary bypass surgery is being advocated over the use of venous conduits. However, there is a critical gap regarding the optimal sequence of arterial conduit selection following the left internal thoracic artery. This study is the first individual patient data meta-analysis, which aimed to compare the right internal thoracic artery (RITA) versus the radial artery (RA) as a second-best arterial conduit. A comprehensive literature search was conducted in MEDLINE, Embase, Scopus, and CENTRAL. A forward-backward citation check was performed to identify other relevant studies. The study protocol was registered in the PROSPERO (CRD42023455543). Eligible studies included randomized controlled trials and propensity-score-matched cohort studies reporting long-term outcomes (>3 years) after coronary bypass surgery using the RITA versus RA as the second arterial conduit after left internal thoracic artery. Overall, long-term survival between the RITA and RA groups showed no significant difference. Landmark analyses demonstrated the superiority of RITA as a second arterial conduit at 1 [hazard ratio (HR): 0.86 (95% CI, 0.75-0.99), P = 0.036], 2 [0.83 (95% CI, 0.72-0.96), P = 0.011], and 5 years [HR: 0.80 (95% CI, 0.68-0.95), P = 0.036] post-surgery. Freedom from major cardiovascular events was significantly higher using the RITA conduit [HR: 0.72 (95% CI, 0.59-0.89), P = 0.002]. This study supports the use of RITA, especially when used in a skeletonized in situ fashion, as a second choice following the left internal thoracic artery as it has the potential to enhance long-term survival and outcomes. Further research with standardized surgical techniques is warranted.
ABSTRACT
Background: Mitral regurgitation (MR) is the most common valvular disease worldwide. MR has been managed surgically, with either a mitral valve replacement or repair. Percutaneous transcatheter mitral valve repair (TMVr) with MitraClip® insertion has gained wide popularity and success over medical and surgical therapy for MR. Some patients with acute MR or decompensated heart failure could benefit from urgent TMVr. This meta-analysis aims to compare clinical outcomes of urgent versus elective TMVr. Methods: We performed a study-level meta-analysis to compare the clinical outcomes of urgent versus elective TMVr using the MitraClip system. The primary endpoint outcome was all-cause mortality. Additional outcomes included procedural success, postoperative acute kidney injury (AKI), stroke, and length of in-hospital stay. Results: Overall, 30-day mortality was significantly higher in the urgent group (odds ratio [OR]: 2.74; 95% confidence interval [CI] [2.17, 3.48]; P < 0.00001; I² =0%). However, subgroup analysis of matched cohorts showed no significant difference between both groups (OR: 1.80; 95% CI [0.94, 3.46]; P = 0.08; I² =0%). One-year mortality was similar between both groups (and: 1.67; 95% CI [0.96, 2.90]; P = 0.07; I² =0%). Procedural success was similar between both groups (89.4% vs. 89.8%; P = 0.43). Postoperative AKI was significantly higher in the urgent group (OR: 4.12; 95% CI [2.87, 5.91]; P < 0.00001; I² =0%). Conclusion: Urgent TMVr should be indicated in select populations as it is considered therapeutic with acceptable outcomes therein.
ABSTRACT
Prosthetic valve endocarditis (PVE) is a rare but serious complication following aortic valve replacement using either a transcatheter aortic valve implantation (TAVI) or surgical aortic valve replacement (SAVR). This study aims to review the profiles and outcomes of PVE after surgical versus transcatheter aortic valve replacement. Electronic searches were performed on Scopus, EMBASE, and PubMed to retrieve related articles. To be included, study designs had to be randomized controlled trials (RCT) or observational cohort studies (in English) with PVE patients that compared differences based on TAVI or SAVR. This review included data for 13,221 patients with PVE diagnoses. Of those, 2,109 patients had an initial SAVR, and 11,112 patients had an initial TAVI. There was no difference in the incidence of PVE in patients who had initial TAVI versus SAVR (1.05% versus 1.01% per person-year, p=0.98). However, the onset of early PVE was more frequently observed in the TAVI group (risk ratio (RR): 1.54, 95% confidence interval (CI) [1.14, 2.08], p=0.005). Patients in the TAVI group had a lower indication for surgery to treat PVE when compared to SAVR (RR: 0.55, 95%CI [0.44, 0.69], p<0.001). Staphylococcus aureus was more likely to be the source of PVE in patients who had previous TAVI (RR: 1.34, 95%CI [1.17, 1.54], p<0.001). Also, Enterococcus faecalis was more frequently observed as a cause of PVE in the TAVI group (RR: 1.49, 95%CI [1.21, 1.82], p<0.001). Patients who underwent SAVR and TAVI had similar incidences of PVE. However, patients who underwent SAVR had a greater indication for surgery to treat PVE, while those who underwent TAVI had higher comorbidities, a higher likelihood of early PVE, and a trend towards higher one-year mortality.
ABSTRACT
There is growing evidence of sex-related differences in the epidemiology and pathophysiology of cardiovascular diseases. This is the first systematic review and meta-analysis that aimed to highlight the sex-specific differences in the clinical features and outcomes of acute myocarditis. Electronic searches were performed on Scopus, Embase, and PubMed from inception up to June 2023 to identify studies comparing the clinical features and outcomes of acute myocarditis in males and females. Both qualitative and quantitative summaries were conducted. In this systematic review and meta-analysis of 11 studies involving 34,791 patients presenting with acute myocarditis. Male patients, who comprised 69.8% of the entire pooled population, presented at a markedly younger age (mean difference: -8.99 years; 95% CI: -13.60, -4.38; p=0.0001). They also had significantly lower rates of hypertension, diabetes mellitus, and coronary artery disease compared to female patients (p<0.01). Male patients were more likely to present with ST elevation (RR: 2.57 [1.38, 4.79]; p=0.003) and higher C-reactive protein levels (RR: 3.04 [2.75, 3.34]; p<0.00001) compared to female patients. This review underscores the crucial sex-specific evaluation in acute myocarditis, necessitating tailored approaches in assessment and diagnostic evaluation, and emphasizing the need for additional research in this domain.
ABSTRACT
Acute type A aortic dissection (ATAAD) is a life-threatening emergency that is associated with a high morbidity and mortality rate. One of the complications is end-organ ischemia, a known predictor of mortality. The primary aims of this meta-analysis were to summarize the findings of observational studies investigating the utility of the Penn classification system and to analyze the incidence rates and mortality patterns within each class. The electronic databases PubMed, MEDLINE, and Embase were searched through to April 2023. These were filtered by multiple reviewers to give 10 studies that met the inclusion criteria. The extracted data included patient characteristics, and primary outcomes were the incidence rates of different Penn classes, along with the corresponding mortality for each class. Out of 1,512 studies identified during the initial search, 10 studies, including 4,494 patients, met the inclusion criteria. The pooled incidence of Penn A was highest at 0.55 (95% CI 0.52, 0.58), followed by Penn B at 0.21 (95% CI 0.17, 0.25), and finally Penn C at 0.14 (95% CI 0.11, 0.17). Patients with Penn BC were found to be at the highest risk of death, as their early mortality rates were 0.36 (95% CI 0.31, 0.41). Within those populations, the subtype with the highest individual mortality was Penn C at 0.21 (95% CI 0.15, 0.27), followed by Penn B at 0.19 (95% CI 0.15, 0.23) and Penn A at 0.07 (95% CI 0.05, 0.10). Among patients presenting with ATAAD, class A was most frequently observed, followed by classes B, C, and BC. These findings indicate an incremental increase in mortality rates with the progression of Penn classification.

BACKGROUND AND OBJECTIVES: Cushing's disease is a rare endocrine disorder. This review aimed to examine sex-specific differences in Cushing's disease. DESIGN AND SETTINGS: A meta-analysis was performed on published articles discussing the gender impact of Cushing's disease. METHODS: A systematic search was conducted to identify studies from Medline, Embase, CENTRAL and Scopus. Nine studies enrolling 1047 patients diagnosed with Cushing's disease were included in this meta-analysis. RESULTS: Male patients presented at a younger age (MD [mean difference]=-5.43; 95% CI [-5.78, -5.08]; P<.00001) than females. Male patients had a significantly higher prevalence of osteoporosis (RR [risk ratio]=1.75; 95% CI [1.36, 225]; P<.0001) and hypokalemia (RR=1.66; 95% CI [1.27, 2.16]; P=.0002). In addition, males had significantly higher rates of negative magnetic resonance imaging (RR=1.53; 95% CI [1.18, 2.0]; P=.002). No sex difference was observed in the prevalence of diabetes (RR=0.92; 95% CI [0.70, 1.22]); P=.57) and dyslipidemia (RR=1.33; 95% CI [0.88, 2.0]; P=.17). CONCLUSION: Cushing's disease has a worse clinical presentation in males and more diagnostic difficulties compared to females.

Transcatheter aortic valve implantation (TAVI) is a common practice for severe aortic stenosis, but the choice between general (GA) and local anesthesia (LA) remains uncertain. We conducted a comprehensive literature review until April 2023, comparing the safety and efficacy of LA versus GA in TAVI procedures. Our findings indicate significant advantages of LA, including lower 30-day mortality rates (RR: 0.69; 95% CI [0.58, 0.82]; p < 0.001), shorter in-hospital stays (mean difference: -0.91 days; 95% CI [-1.63, -0.20]; p = 0.01), reduced bleeding/transfusion incidents (RR: 0.64; 95% CI [0.48, 0.85]; p < 0.01), and fewer respiratory complications (RR: 0.56; 95% CI [0.42, 0.76], p<0.01). Other operative outcomes were comparable. Our findings reinforce prior evidence, presenting a compelling case for LA's safety and efficacy. While patient preferences and clinical nuances must be considered, our study propels the discourse towards a more informed anaesthesia approach for TAVI procedures.

Conventional elephant trunk (cET) and frozen elephant trunk (FET) are two distinct approaches to the surgical treatment of thoracic aortic aneurysms and dissections. With the advent and growing uptake of endovascular technologies, FET is becoming increasingly popular for its potential to be performed as a single-stage operation with better aortic remodeling and less risk of graft kinking than the traditional two-stage cET procedure. However, FET has been associated with a higher risk of spinal cord ischemia and its use in patients with connective tissue disorder remains controversial. The current review aimed to reflect on recent evidence surrounding the application of cET and FET to different types of aortic pathology in both acute and elective settings. Another scope of this review was to compare the characteristics of the currently available FET commercial devices on the global market. Our findings highlight that when the pathology is confined to the proximal descending aorta, such as in Dsine, intervention is often single-staged and false lumen (FL) thrombosis is achieved with good effect. FET remains limited by spinal cord injury and applicability in patients with connective tissue disorder, although some groups have started to circumvent associated complications, likely due to growing surgical expertise. Many other aortic diseases do require second-stage intervention, and even in these cases, there appears to be lower in-hospital mortality when using FET over cET. This is possibly due to the higher rate of endovascular completion facilitated by the completed landing zones created during FET. FET is trending toward becoming the universal treatment modality for extending repair to the descending aorta.
