Meta-Analysis Review
Sutureless closure has been used for primary repair of total anomalous pulmonary venous connection (TAPVC) for over 20 years but its superiority over conventional technique is still uncertain. This systematic review was conducted to compare the effectiveness of sutureless closure and conventional surgery as the primary repair for TAPVC. Systematic search was performed in June 2021 on 12 databases. All studies comparing sutureless and conventional surgery for TAPVC were included. The primary endpoints were early mortality, overall mortality, postoperative pulmonary venous stenosis (PVS), and reoperation. Meta-analysis of two-arm studies was performed with several sensitivity and subgroup analyses. Six retrospective studies with 767 patients were included in meta-analyses. Sutureless closure significantly reduced the risk of early mortality, overall mortality, postoperative PVS, and reoperation by 53%, 45%, 77%, and 67% compared to conventional technique, respectively. No heterogeneity was found and presence of publication bias was non-significant. The results were consistent in all sensitivity analyses. Subgroup analyses revealed that sutureless closure was superior to conventional technique in patients with and without preoperative pulmonary venous obstruction, and neonates and non-neonates. Sutureless closure is better than conventional closure as the primary surgery for TAPVC patients. We advocate using sutureless closure for patients with TAPVC. Future large-scale observational studies or clinical trials are required to confirm our findings.

Review
Twelve CCI patients were studied with confirmed or suspected COVID-19 infection. The majority of these patients were males (83.3%) with a median age of 55 years from three geographical locations, constituting the Middle East (7), Spain (3), and the USA (1). In 6 patients, IgG/IgM was positive for COVID-19, 4 with high pretest probability and 2 with positive RT-PCR. Type 2 DM, hyperlipidemia, and smoking were the primary risk factors. Right-sided neurological impairments and verbal impairment were the most common symptoms. Our analysis found 8 (66%) synchronous occurrences. In 58.3% of cases, neuroimaging showed left Middle Cerebral Artery (MCA) infarct and 33.3% right. Carotid artery thrombosis (16.6%), tandem occlusion (8.3%), and carotid stenosis (1%) were also reported in imaging. Dual antiplatelet therapy (DAPT) and anticoagulants were conservative therapies (10). Two AMI patients had aspiration thrombectomy, while three AIS patients had intravenous thrombolysis/tissue plasminogen activator (IVT-tPA), 2 had mechanical thrombectomy (MT), and 1 had decompressive craniotomy. Five had COVID-19-positive chest X-rays, whereas 4 were normal. four of 8 STEMI and 3 NSTEMI/UA patients complained chest pain. LV, ICA, and pulmonary embolism were further complications (2). Upon discharge, 7 patients (70%) had residual deficits while 1 patient unfortunately died.

BACKGROUND
Airway complications seriously affect the clinical outcomes and long-term prognosis of lung-transplantation patients. Airway stenting provides effective palliation for patients with airway stenosis. However, a lack of consensus regarding the efficacy and safety of airway stents in airway stenosis after lung transplantation. This study critically evaluated all available evidence regarding this concern.
METHODS
We retrieved studies from EMBASE, PubMed, and Cochrane Library databases. Studies were included if they reported baseline characteristics of airway complications after lung transplantation, stenting for airway stenosis, or prognosis.
RESULTS
In total, 279 papers were screened and 17 papers were included in final analysis. The short-term efficacy of airway stenting was assessed in almost all studies, with immediate palliation in symptom and improved pulmonary function reported. Eleven of the included studies evaluated the long-term efficacy of stent therapy, with no distinct lung function. The median overall survival time was 1,124 (95% confidence interval 415-1,833) days in stented patients only. Stent-related complications are common regardless of the material; However, serious complications are rare and can be improved with routine management.
CONCLUSION
We demonstrated that airway stenting is a safe and effective method to treat airway stenosis after lung transplantation. The short-term effect was significant, while the long-term efficacy on survival rate needed further investigations.

Meta-Analysis
BACKGROUND
Ischemia at the anastomotic site plays a critical role determinant in the development of anastomosis-related complications after esophagectomy. Gastric ischemic conditioning (GIC) before esophagectomy has been described to improve the vascular perfusion at the tip of the gastric conduit with a potential effect on anastomotic leak (AL) and stenosis (AS) risk minimization. Laparoscopic (LapGIC) and angioembolization (AngioGIC) techniques have been reported.
PURPOSE
Compare short-term outcomes among different GIC techniques.
MATERIALS AND METHODS
Systematic review and network meta-analysis. One-step esophagectomy (noGIC), LapGIC, and AngioGIC were compared. Primary outcomes were AL, AS, and gastric conduit necrosis (GCN). Risk ratio (RR) and weighted mean difference (WMD) were used as pooled effect size measures, whereas 95% credible intervals (CrIs) were used to assess relative inference.
RESULTS
Overall, 1760 patients (14 studies) were included. Of those, 1028 patients (58.4%) underwent noGIC, 593 (33.6%) LapGIC, and 139 (8%) AngioGIC. AL was reduced for LapGIC versus noGIC (RR=0.68; 95% CrI 0.47-0.98) and AngioGIC versus noGIC (RR=0.52; 95% CrI 0.31-0.93). Similarly, AS was reduced for LapGIC versus noGIC (RR=0.32; 95% CrI 0.12-0.68) and AngioGIC versus noGIC (RR=1.30; 95% CrI 0.65-2.46). The indirect comparison, assessed with the network methodology, did not show any differences for LapGIC versus AngioGIC in terms of postoperative AL and AS risk. No differences were found for GCN, pulmonary complications, overall complications, hospital length of stay, and 30-day mortality among different treatments.
CONCLUSIONS
Compared to noGIC, both LapGIC and AngioGIC before esophagectomy seem equivalent and associated with a reduced risk for postoperative AL and AS.

Review
Patients with symptomatic aortic stenosis (AS) commonly have an associated finding of pulmonary hypertension (PH), and it has been previously shown to have increased morbidity and mortality following surgical aortic valve repair (SAVR) as well as transcatheter aortic valve implantation (TAVI). There are no guidelines stating the cut-off point for PH at which the patient can safely undergo TAVI with benefits outweighing the risks. This is partly due to the lack of uniformity in the PH definition used in various studies. This systematic review sought to study the effect of preprocedural pulmonary hypertension on early and late all-cause and cardiac mortality in patients undergoing TAVI. We performed a systematic review of studies comparing patients with AS undergoing TAVI having PH. The review was undertaken as per Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Articles were identified from PubMed, Pubmed Central (PMC), Cochrane, and Medline on January 10, 2022, for literature published until January 10, 2022. MeSH strategy was used on PubMed to search the literature, and filters were applied to search only Observational Studies, randomized controlled trials (RCT), and meta-analysis. A total of 170 unique articles were identified and screened. Of the 33 full-text articles that were reviewed, 18 articles, including duplicates, were excluded. Fifteen articles fulfilled the selection criteria and were included in this review. The study design included two meta-analyses, one randomized control trial, one prospective cohort study, and 11 retrospective cohort studies. The studies involved a total of approximately 30,000 patients. The observational studies in our review were of good to fair quality, the RCT had a low to moderate bias, and the meta-analysis was of moderate quality. Baseline PH and persistence of PH post-TAVI are strongly associated with all-cause and cardiac mortality. Few studies have shown that a decrease in post-TAVI PH carries mortality benefits. Therefore, efforts should be made to identify mechanisms of persistent PH post-TAVI and whether interventions to reduce PH pre-TAVI will have any clinical implications or not by conducting RCT.

Meta-Analysis Review
BACKGROUND
Congenital malformations are considered as one of the significant causes of preterm as well as neonatal morbidity and mortality. Literature suggests the association of diverse congenital deformities with maternal exposure to air pollutants. However, the evidence is still inconclusive on the manifestation of these during pregnancy. Thus, systematic review was done on the available epidemiological studies studying the effect of air pollutants on congenital malformations. Furthermore, the meta-analysis was conducted for several combinations of air pollutants and congenital defects.
METHODS
Twenty six epidemiological studies were extracted from the databases and examined for association of risk of congenital defects with air pollutant concentrations. Metaanalysis was done if the risk estimates of the same anomaly and pollutant group were reported in at least three studies.
RESULTS
Each study reported a statistically significant increased risk of congenital malformation with some air pollutant, amid the several tested combinations. Our meta-analysis reported that nitrogen dioxide and PM were associated with the risk of pulmonary valve stenosis with OR = 1.74 and OR = 1.42 respectively. The risk of developing tetralogy of Fallot (TOF) was observed to be associated with PM with OR = 1.52 SO exposure was related to a high risk of the ventricular septal defect (VSD) with OR = 1.15 and orofacial defects (OR = 1.27).
CONCLUSION
It is evidenced that ambient air pollutants have some effect on congenital malformations. Standard case definitions, improved methods of exposure, and better control of confounders will improve future research in this area.

Meta-Analysis
BACKGROUND
Pulmonary artery obstruction is an uncommon but significant complication after lung transplantation. Although numerous reports have documented its occurrence, the hemodynamic parameters associated with its presentation and diagnostic considerations remain ill-defined. This systematic review summarizes evidence in the literature surrounding pulmonary artery obstruction after lung transplantation surgery.
METHODS
Databases were searched for all articles and abstracts reporting on pulmonary artery obstruction. Data collected included the number of patients studied, patient characteristics, incidences of pulmonary artery obstruction, and timing and imaging modality used for diagnosis.
RESULTS
Thirty-four full-text citations were included in this review. The point prevalence of pulmonary artery obstruction was 3.66%. The peak pulmonary artery velocity associated with obstruction was found to be 2.60 ± 0.58 m/s. The diameter of the obstructed pulmonary artery predictive of poor outcomes was noted to be 0.78 ± 0.40 cm. The majority of diagnoses were made in the late postoperative period using pulmonary angiogram and transesophageal echocardiography. Overall, 76% of patients (47 of 62) required emergent procedural reintervention, and 23% of patients (14 of 62) diagnosed with pulmonary artery obstruction died during their hospital stay.
CONCLUSIONS
This systematic review underscores the importance of identifying pulmonary artery obstruction immediately after lung transplant surgery. The clinical implications of these results warrant the development of identification and management strategies for early detection of irregularities in pulmonary artery anastomosis in lung transplant patients.

Review
Pulmonary valve replacement (PVR) is the most common cardiac operation in adult patients with congenital heart disease (ACHD). It can improve right ventricular outflow tract (RVOT) obstruction, typically due to pulmonary valve stenosis or regurgitation. PVR can be performed surgically (open-heart) and through a transcatheter (percutaneous) method, which is minimally invasive and is associated with shorter hospitalization stays. However, following PVR, infectious endocarditis (IE) can complicate the recovery process and increase mortality in the long term. IE is a rare but deadly multi-organ system condition caused by microorganisms traversing the bloodstream from a specific entry point. It can have many presentations, such as splinter hemorrhages, fevers, and vegetation on valves that lead to stroke consequences. This paper aims to evaluate the differences in the rate, etiology, manifestations, treatment, and outcomes of IE following surgical and transcatheter PVR, as the goal is to perform a procedure with few complications. In both approaches, was the most common microorganism that affected the valves, followed by . Research has shown that surgical pulmonary valve replacement (SPVR) has a decreased risk of IE following surgery compared to TPVR. However, TPVR is preferred due to the reduced overall risk and complications of the procedure. Despite this, the consensus on mortality rates does differ. Future research should consider the type of valves used for transcatheter pulmonary valve replacement (TPVR), such as Melody valves versus Edward Sapien valves, as their IE rates vary significantly.

Absent pulmonary valve (APV) syndrome with tricuspid atresia or tricuspid stenosis (TA/TS) is an extremely rare malformation recently reported as a variant of APV with intact ventricular septum (VS). The condition, however, has univentricular physiology and unique structural and clinical features. The purpose of this study was to update the current knowledge about this condition by describing long-term outcomes of three new cases and reviewing the available literatures. A systematic literature search was performed to collect clinical and anatomical data of APV with TA/TS. Institutional medical records were retrospectively reviewed to identify APV with TA/TS patients. In a total of 62 (59 reported and 3 new) cases, patent ductus arteriosus was present in 98% of APV patients with TA/TS. A large ventricular septal defect, dilatation of the pulmonary arteries, which is typically found in APV with tetralogy of Fallot, and respiratory distress at birth were rarely reported. Most of the recent cases were successfully managed by the Glenn or Fontan procedure. Coronary artery anomaly and ventricular arrhythmia were more frequently reported as the cause of death or severe neurological sequelae (9/16 and 3/8, respectively). Additional surgical intervention was required in the mid/long-term period in three cases due to left-ventricular outflow obstruction and in two due to aortic dilatation. The Fontan and Glenn procedures improved the survival in the last two decades. In addition to coronary artery anomaly and ventricular arrhythmia, left-ventricular outflow tract obstruction and aortic dilatation should be carefully monitored.

Meta-Analysis Review
BACKGROUND AND AIMS
Chronic obstructive pulmonary disease (COPD) is associated with increased cardiovascular morbidity and mortality. Identifying early changes of cardiovascular system before the occurrence of fatal clinical event is critical for the management of COPD. We performed a meta-analysis to investigate the associations between COPD and subclinical markers of cardiovascular risk.
METHODS
We searched PUBMED, EMBASE for studies published before Aug 1st, 2016, on the association between COPD and carotid intima-media thickness (CIMT), prevalence of carotid plaques, flow-mediated dilation (FMD), pulse-wave velocity (PWV) and augmentation index (AIx).
RESULTS
Thirty-two studies (3198 patients, 13867 controls) were included. Compared with controls, COPD patients had significantly higher CIMT (MD: 0.10 mm; 95% CI: 0.04, 0.16; p = 0.0007), PWV (SMD: 0.70; 95% CI: 0.52, 0.88; p < 0.0001), AIx (MD: 4.60%; 95% CI: 0.52, 8.68; p = 0.03), AIx@75 (AIx normalized to a heart rate of 75 beats per minute) (MD: 4.59%; 95% CI: 2.80, 6.38; p < 0.0001), prevalence of carotid plaque (OR: 2.54; 95% CI: 2.04, 3.15; p < 0.0001), and significantly lower FMD (MD: -4.21%; 95% CI: -6.71, -1.71; p = 0.001). Sensitivity and subgroups analyses substantially confirmed our results. Meta-regression analysis revealed that spirometry (as expressed by FEV%predicted) might influence on PWV.
CONCLUSIONS
These findings indicate that COPD, even in mild to moderate patients, had greater impaired markers of subclinical atherosclerosis and cardiovascular risk. However, further studies are still needed to address confounders, such as age, smoking, hypertension, diabetes etc, which might affect the associations in COPD patients.
