Review
The effects of percutaneous branch pulmonary artery interventions on exercise capacity, lung perfusion, and right ventricular function in biventricular CHD: a systematic review.
BACKGROUND
Branch pulmonary artery stenosis is common after surgical repair in patients with biventricular CHD and often requires reinterventions. However, (long-term) effects of percutaneous branch pulmonary artery interventions on exercise capacity, right ventricular function, and lung perfusion remain unclear. This review describes the (long-term) effects of percutaneous branch pulmonary artery interventions on exercise capacity, right ventricular function, and lung perfusion following PRISMA guidelines.
METHODS
We performed a systematic search in PubMed, Embase, and Cochrane including studies about right ventricular function, exercise capacity, and lung perfusion after percutaneous branch pulmonary artery interventions. Study selection, data extraction, and quality assessment were performed by two researchers independently.
RESULTS
In total, 7 eligible studies with low (n = 2) and moderate (n = 5) risk of bias with in total 330 patients reported on right ventricular function (n = 1), exercise capacity (n = 2), and lung perfusion (n = 7). Exercise capacity and lung perfusion seem to improve after a percutaneous intervention for branch pulmonary artery stenosis. No conclusions about right ventricular function or remodelling, differences between balloon and stent angioplasty or specific CHD populations could be made.
CONCLUSION
Although pulmonary artery interventions are frequently performed in biventricular CHD, data on relevant outcome parameters such as exercise capacity, lung perfusion, and right ventricular function are largely lacking. An increase in exercise capacity and improvement of lung perfusion to the affected lung has been described in case of mild to more severe pulmonary artery stenosis during relatively short follow-up. However, there is need for future studies to evaluate the effect of pulmonary artery interventions in various CHD populations.

Meta-Analysis
The predictive value of baseline pulmonary hypertension in early and long term cardiac and all-cause mortality after transcatheter aortic valve implantation for patients with severe aortic valve stenosis: A systematic review and meta-analysis.
BACKGROUND
Transcatheter aortic valve implantation (TAVI) is a safe and effective alternative to surgical aortic valve replacement (SAVR) for the treatment of severe aortic valve stenosis (AS). The impact of concomitant baseline elevated pulmonary artery pressures on outcomes after TAVI has not been established, since different studies used different definitions of pulmonary hypertension (PH).
OBJECTIVE
To determine the association of PH with early and late cardiac and all-cause mortality after TAVI.
METHODS
We performed a meta-analysis of studies comparing patients with elevated pulmonary artery pressures (defined as pulmonary hypertension or not) versus patients without elevated pulmonary artery pressures undergoing TAVI. We first performed stratified analyses based on the different PH cut-off values utilized by the included studies and subsequently pooled the studies irrespective of their cut-off values. We used a random effects model for the meta-analysis and assessed heterogeneity with I-square. Separate meta-analyses were performed for studies reporting outcomes as hazards ratios (HRs) and relative risks (RRs). Subgroup analyses were performed for studies published before and after 2013. Meta-regression analysis in order to assess the effect of chronic obstructive pulmonary disease and mitral regurgitation were performed.
RESULTS
In total 22 studies were included in this systematic review. Among studies presenting results as HR, PH was associated with increased late cardiac mortality (HR: 1.8. 95% CI: 1.3-2.3) and late all-cause mortality (HR: 1.56; 95% CI: 1.1-2). The PH cut-off value that was most likely to be associated with worst outcomes among the different endpoints was pulmonary artery systolic pressure of 60 mm Hg (HR: 1.8; 95% CI: 1.3-2.3; I = 0, for late cardiac mortality and HR: 1.52; 95% CI: 1-2.1; I = 85% for late all-cause mortality).
CONCLUSION
This systematic review and meta-analysis emphasizes the importance of baseline PH in predicting mortality outcomes after TAVI. Additional studies are needed to clarify the association between elevated baseline pulmonary artery pressures and outcomes after TAVI.

Synchronous versus Staged Carotid Endarterectomy and Coronary Artery Bypass Graft for Patients with Concomitant Severe Coronary and Carotid Artery Stenosis: A Systematic Review and Meta-analysis.
BACKGROUND
Due to the systemic nature of atherosclerosis, arteries at different sites are commonly simultaneously affected. As a result, severe coronary artery disease (CAD) requiring coronary artery bypass grafting (CABG) frequently coexists with significant carotid stenosis that warrants revascularization. To compare simultaneous carotid endarterectomy (CEA) and CABG versus staged CEA and CABG for patients with concomitant CAD and carotid artery stenosis in terms of perioperative outcomes.
METHODS
This study was performed according to the Preferred Reporting Items for Systematic reviews and Meta-Analyses guidelines. A meta-analysis was conducted with the use of a random effects model. The I statistic was used to assess for heterogeneity.
RESULTS
Eleven studies comprising 44,895 patients were included in this meta-analysis (21,710 in the synchronous group and 23,185 patients in the staged group). The synchronous CEA and CABG group had a statistically significant lower risk for myocardial infarction (MI) (odds ratio [OR] 0.15, 95% CI 0.04-0.61, I = 0%) and higher risk for stroke (OR 1.51, 95% CI 1.34-1.71, I = 0%) and death (OR 1.33, 95% CI 1.01-1.75, I = 47.8%). Transient ischemic attacks (TIAs) (OR 1.27, 95% CI 1.00-1.61, I = 0.0%), postoperative bleeding (OR 0.82, 95% CI 0.22-3.05, I = 0.0%), and pulmonary complications (OR 1.52, 95% CI 0.24-9.60, I = 67.5%) were similar between the 2 groups.
CONCLUSIONS
Patients in the simultaneous CEA and CABG group had a significantly higher risk of 30-day mortality and stroke and lower risk for MI as compared to staged CEA and CABG group. The rates of TIA, postoperative bleeding, and pulmonary complications were similar between the 2 groups. Future randomized trials or prospective cohorts are needed to validate our results.

Review
Maternal prepregnancy weight as an independent risk factor for congenital heart defects: systematic review and meta-analysis stratified by cardiac defect subtypes and severity.
OBJECTIVES
To assess and quantify the association between pre-pregnancy maternal overweight and obesity, and the risk of congenital heart defects (CHDs) in offspring.
METHODS
This systematic review and meta-analysis included searches of PubMed, Medline, Web of science, and Scopus up to April 20th, 2023. Risk estimates were abstracted or calculated for rising body mass index categories (overweight, obesity, moderate and severe obesity) compared to normal weight (reference). Fixed-effects or random-effects models were used to combine individual study risk estimates based on the degree of heterogeneity. Sensitivity analyses were conducted to weight pooled estimates for relevant moderators, particularly diabetes prior and during pregnancy. Subgroup analyses for specific congenital heart defects were conducted if there were at least two studies with accessible data. The findings were presented in two ways: as groups of defects, categorized using severity and topographic-functional criteria, and as individual defects. The certainty of the evidence for each effect estimate was evaluated according to the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) guidelines.
RESULTS
Twenty studies for a total of 4,861,693 patients and 86,136 CHDs cases were included. The risk for CHDs progressively increases from moderate to severe obesity (pooled odds ratio (OR), respectively: 1.15, 95% confidence interval (CI), 1.11-1.20, and 1.39, 95% CI, 1.27-1.53). Sensitivity analysis indicated that this effect persists independently of maternal diabetes status before or during pregnancy. In subgroup analysis, obesity was associated with up to a 1.5-fold increase in the risk of severe CHDs (pooled OR, 1.48; 95% CI, 1.03-2.13). Specifically, severe obesity was found to be associated with an even higher risk, increasing up to 1.8 times for specific CHDs including tetralogy of Fallot (pooled OR, 1.72; 95% CI, 1.38-2.16), pulmonary valve stenosis (pooled OR, 1.79; 95% CI, 1.39-2.30), and atrial septal defects (pooled OR, 1.71; 95% CI, 1.48-1.97).
CONCLUSIONS
Maternal weight emerged as a crucial modifiable risk factor for preventing CHDs, particularly the severe forms. Future research is needed to investigate whether weight management prior to pregnancy might serve as a preventive measure against CHDs. Additionally, for pregnant women with obesity, fetal echocardiography ought to be a routine diagnostic procedure. This article is protected by copyright. All rights reserved.

Meta-Analysis
BACKGROUND
This meta-analysis aimed to compare the potential effects of local anesthesia (LA) and general anesthesia (GA) for transcatheter aortic valve implantation (TAVI).
MEASUREMENTS
All relevant studies were searched from Pubmed, EMbase, Web of Science, and the Cochrane Library (January 1, 2016, to June 1, 2021). The main outcomes of this literature meta-analysis were 30-day mortality, procedural time, new pacemaker implantation, total stay in the hospital, use of the vasoactive drug, and intra-and postoperative complications and emergencies, including conversion to open, myocardial infarction, pulmonary complication, vascular complication, renal injury/failure, stroke, transesophageal echocardiography, life-threatening/major bleeding, cardiac tamponade, and emergency PCI. Pooled risk ratio (RR) and mean difference (MD) together with a 95% confidence interval (CI) were calculated.
RESULTS
A total of 17 studies, including 20938 patients, in the final analysis, fulfilled the inclusion criteria. Intra-and postoperative complications (myocardial infarction, vascular complication, renal injury/failure, stroke, and cardiac tamponade) undergoing TAVI in severe AS patients under GA do not offer a significant difference compared with LA. No differences were observed between LA and GA for new pacemaker implantation, total stay in the hospital, transesophageal echocardiography, and emergency PCI. LA has lower mortality compared with GA (RR 0.69, P = 0.600), pulmonary complications (RR 0.54, P = 0.278), life-threatening/major bleeding (RR 0.85, P = 0.855), and lower times of conversion to open (RR 0.22, P = 0.746). LA has many advantages, including a shorter procedure duration (MD=-0.38, P = 0.000) and reduction of the use of the vasoactive drug (RR 0.57, P = 0.000).
CONCLUSIONS
For TAVI, both LA with or without sedation and GA are feasible and safe. LA appears a feasible alternative to GA for AS patients undergoing TAVI.

Review
A systematic review was conducted in compliance with PRISMA statement standards to identify all studies reporting outcomes of laparoscopic resection of benign or malignant lesions located in caudate lobe of liver. Pooled outcome data were calculated using random-effects models. A total of 196 patients from 12 studies were included. Mean operative time, volume of intraoperative blood loss, and length of hospital stay were 225 minutes (95% confidence interval [CI], 181-269 minutes), 134 mL (95% CI, 85-184 mL), and 7 days (95% CI, 5-9 days), respectively. The pooled risk of need for intraoperative transfusion was 2% (95% CI, 0%-5%). It was 3% (95% CI, 1%-6%) for conversion to open surgery, 6% (95% CI, 0%-19%) for need for intra-abdominal drain, 1% (95% CI, 0%-3%) for postoperative mortality, 2% (95% CI, 0%-4%) for biliary leakage, 2% (95% CI, 0%-4%) for intra-abdominal abscess, 1% (95% CI, 0%-4%) for biliary stenosis, 1% (95% CI, 0%-3%) for postoperative bleeding, 1% (95% CI, 0%-4%) for pancreatic fistula, 2% (95% CI, 1%-5%) for pulmonary complications, 1% (95% CI, 0%-4%) for paralytic ileus, and 1% (95% CI, 0%-4%) for need for reoperation. Although the available evidence is limited, the findings of the current study might be utilized for hypothesis synthesis in future studies. They can be used to inform surgeons and patients about estimated risks of perioperative complications until a higher level of evidence is available.

Meta-Analysis Review
The aim of this study was to investigate the relationship between maternal body mass index and all congenital heart defects (CHDs) combined and 11 individual defects. PubMed, ELSEVIER ScienceDirect, and Springer Link (up to February 2013) were searched, and the reference list of retrieved articles was reviewed. Three authors independently extracted the data. The systematic review included 24 studies, 14 of which were included in a metaanalysis. Statistical software was used to perform all statistical analyses. Fixed-effects or random-effects model was used to pool the results of individual study (expressed as odds ratios [ORs] with 95% confidence intervals [CIs]). A dose-response effect was observed between overweight, moderate obesity, and severe obesity and a pregnancy with any CHD (the pooled ORs: OR, 1.08 [95% CI, 1.02-1.15]; OR, 1.15 [95% CI, 1.11-1.20]; and OR, 1.39 [95% CI, 1.31-1.47], respectively) as well as some individual defects such as hypoplastic left heart syndrome, pulmonary valve stenosis, and outflow tract defects. When we excluded mothers with diabetes mellitus, the pooled ORs for all CHDs combined were 1.12 (95% CI, 1.04-1.20) and 1.38 (95% CI, 1.20-1.59) for moderately obese and severely obese, respectively. The highest increased risk was severely obese mothers for tetralogy of Fallot (OR, 1.94; 95% CI, 1.49-2.51). Being underweight did not increase the risk of any of the aforementioned CHDs but did increase the risk of aortic valve stenosis (OR, 1.47; 95% CI, 1.01-2.15]). The results of our study showed that increasing maternal body mass index was associated with an increasing risk of CHDs; severe obesity was an even greater risk factor for the development of CHDs.

OBJECTIVES
In the last decade, percutaneous treatment of valve disease has changed the approach toward the treatment of aortic stenosis (AS) and mitral regurgitation (MR). The clinical usefulness of stress echocardiography (SE) in the candidates for transcatheter aortic valve implantation (TAVI) and transcatheter edge-to-edge repair (TEER) of MR remains to be established. Therefore, the key aim of this review is to assess the main applications of SE in patients undergoing TAVI or TEER.
METHODS
We searched for relevant studies to be included in the systematic review on PubMed (Medline), Cochrane library, Google Scholar, and Biomed Central databases. The literature search was conducted in February 2022. The inclusion criteria of the studies were: observational and clinical trials or meta-analysis involving patients with AS or MR evaluated with SE (excluding those in which SE was used only for screening of pseudo-severe stenosis) and treated with percutaneous procedures.
RESULTS
Thirteen studies published between 2013 and 2021 were included in the review: five regarding candidates for TEER and eight for TAVI. In TEER candidates, seeing an increase in MR grade, and stroke volume of >40% during SE performed before treatment was, respectively, related to clinical benefits ( = 0.008) and an increased quality of life. Moreover, overall, 25% of patients with moderate secondary MR at rest before TEER had the worsening of MR during SE. At the same time, in SE performed after TEER, an increase in mean transvalvular diastolic gradient and in systolic pulmonary pressure is expected, but without sign and symptoms of heart failure. Regarding TAVI, several studies showed that contractile reserve (CR) is not predictive of post-TAVI ejection fraction recovery and mortality in low-flow low-gradient AS either at 30 days or at long-term.
CONCLUSION
This systematic review shows in TEER candidates, SE has proved useful in the optimization of patient selection and treatment response, while its role in TAVI candidates is less defined. Therefore, larger trials are needed to test and confirm the utility of SE in candidates for percutaneous procedures of valve diseases.

Meta-Analysis
BACKGROUND
Assessment of right ventricular (RV) function in aortic stenosis (AS) may improve risk stratification. However, whether the prognostic value of RV free-wall longitudinal strain (RVfwLS) is better than that of other right heart or pulmonary circulation parameters remains uncertain. This study assessed and compared the prognostic value of RVfwLS with traditional parameters in the AS population using a systematic review and meta-analysis.
METHODS
We selected studies reporting the hazard ratio (HR) of RVfwLS in patients with AS. We also collected data regarding the HR of systolic pulmonary arterial pressure (SPAP), fractional area change (FAC), and tricuspid annulus plane systolic excursion (TAPSE). To ensure comparability, we standardized the HR using within-study standard deviations. The comparison between the prognostic value of RVfwLS and other parameters was conducted as a ratio of HR.
RESULTS
This meta-analysis included 9 studies comprising a total of 2547 patients, with 679 events. The pooled HR of RVfwLS was 1.56 (95 % CI: 1.39-1.75, p < 0.001). When examining the ratio of HR between RVfwLS and conventional parameters, all comparisons were statistically non-significant [RVfwLS/SPAP: 1.28 (95 % CI: 0.99-1.65, p = 0.06); RVfwLS/FAC: 1.24 (95 % CI: 0.90-1.72, p = 0.14); and RVfwLS/TAPSE:1.07 (95 % CI: 0.75-1.52, p = 0.60)].
CONCLUSIONS
This meta-analysis establishes a substantial association between RVfwLS and adverse outcomes in the AS population. However, comparative analysis between RVfwLS and SPAP, FAC, or TAPSE did not support the prognostic superiority of RVfwLS.
