OBJECTIVES
Transannular patch (TAP) repair of tetralogy of Fallot (ToF) relieves right ventricular tract obstruction but may lead to pulmonary regurgitation. Valve-sparing (VS) procedures can avoid this but there is potential for residual pulmonic stenosis. We aimed to evaluate clinical and echocardiographic outcomes of TAP and VS repair for ToF.
METHODS
A systematic search of the PubMed, Embase, Scopus, CENTRAL (Cochrane Central Register of Controlled Trials), and Web of Science databases was carried out to identify articles comparing conventional TAP repair and VS repair for ToF. Clinical and echocardiographic outcomes were meta-analyzed using random-effects models.
RESULTS
40 studies were included in this meta-analysis with data on 11,723 participants (TAP: 6,171; VS: 5,045). Participants that underwent a VS procedure experienced a significantly lower cardiopulmonary bypass time (MD: -14.97; 95% CI: -22.54, -7.41), shorter ventilation duration (MD: -15.33; 95% CI: -30.20, -0.46), and shorter lengths of both ICU (MD: -0.67; 95% CI: -1.29, -0.06) and hospital stay (MD: -2.30; 95% CI: [-4.08, -0.52). There was also a lower risk of mortality (RR: 0.40; 95% CI: [0.27, 0.60]) and pulmonary regurgitation (RR: 0.35; 95% CI: [0.26, 0.46]) associated with the VS group. Most other clinical and echocardiographic outcomes were comparable in the two groups.
CONCLUSIONS
This meta-analysis confirms the well-established increased risk of pulmonary insufficiency following TAP repair, while also demonstrating that VS repairs are associated with several improved clinical outcomes. Continued research can identify the criteria for adopting a VS approach as opposed to a traditional TAP repair.

Meta-Analysis Review
The outcomes of total and bicaval heart transplantation techniques are better than those of the biatrial technique; however, the latter is still considered the gold-standard. The objective of this study was to determine whether the total and bicaval heart transplantation techniques are, in fact, better than the biatrial technique. A systematic review with meta-analysis was carried out. Studies were retrieved from Pubmed, Lilacs, Web of Science, Scirus, Scopus, Google Scholar, and Scielo databases, identified by sensitive strategy. Randomized, prospective, and retrospective controlled studies were selected for inclusion. Intra and postoperative parameters were assessed. A total of 11,602 studies were identified and 36 were included in our review. The number of atrial arrhythmias, tricuspid valve regurgitation, deaths, and embolic events, as well as bleeding volume; temporary and permanent pacemaker requirement; and length of stay in the intensive care unit are significantly lower for the total and bicaval techniques than for the biatrial technique. Also, hemodynamic variables such as pulmonary capillary pressure, mean pulmonary artery pressure, and right atrial pressure are lower in total and bicaval transplantation. In prognostic terms, total and bicaval orthotopic heart transplantations are better, than the biatrial transplantation. Therefore, indication of the biatrial technique for transplantation should be the exception, not the rule.

BACKGROUND
Very few data exist on percutaneous mitral valve repair (PMVr) in unstable patients with concomitant moderate-severe mitral regurgitation (MR). The purpose of this systematic review was to evaluate baseline characteristics, management and clinical outcomes of critically ill patients undergoing PMVr with MitraClip.
METHODS
We conducted a systematic review of the published data on MitraClip from its first use in 2003 to December 2020. Studies referring to critically ill patients in cardiogenic shock or acute refractory pulmonary edema were included. A total of 40 publications including 254 patients with significant MR (Grade 4 in 91%) were included.
RESULTS
Mean age was 70 ± 12 years with mean Euroscore II and STS of 21 ± 13 and 20.5 ± 16, respectively. Clinical presentation was with cardiogenic shock and acute myocardial infarction in 72.8 and 60.0% of patients, respectively. Device success was achieved in 238 (93.7%) patients with a significant reduction in MR (Grade ≤ 2 in 91.8%, p < .001). The median weaning time from the procedure, to discontinuation of mechanical circulatory or respiratory support, was 2 days (IQR 1-4), with an in-hospital mortality and non-fatal complication rate of 12.6 and 9.1%, respectively. Kaplan-Meier curves estimated an overall mortality rate of 39.1% at 12-month follow-up, with persistent reduction in MR severity for survivors (Grade ≤ 2 in 81.3%) and one case of mitral valve reintervention.
CONCLUSIONS
Percutaneous mitral valve repair with MitraClip device is a technically feasible and potentially viable management option in high-risk patients with cardiogenic shock or refractory pulmonary edema and concomitant moderate-severe MR. Prospective trials are required to confirm these findings, and definitively determine the value of MitraClip in hemodynamically unstable patients.

Meta-Analysis Review
BACKGROUND
Cardiac surgery triggers a strong inflammatory reaction, which carries significant clinical consequences. Corticosteroids have been suggested as a potential perioperative strategy to reduce inflammation and help prevent postoperative complications. However, the safety and effectiveness of perioperative corticosteroid use in adult cardiac surgery is uncertain. This is an update of the 2011 review with 18 studies added.
OBJECTIVES
Primary objective: to estimate the effects of prophylactic corticosteroid use in adults undergoing cardiac surgery with cardiopulmonary bypass on the: - co-primary endpoints of mortality, myocardial complications, and pulmonary complications; and - secondary outcomes including atrial fibrillation, infection, organ injury, known complications of steroid therapy, prolonged mechanical ventilation, prolonged postoperative stay, and cost-effectiveness.
SECONDARY OBJECTIVE
to explore the role of characteristics of the study cohort and specific features of the intervention in determining the treatment effects via a series of prespecified subgroup analyses.
SEARCH METHODS
We used standard, extensive Cochrane search methods to identify randomised studies assessing the effect of corticosteroids in adult cardiac surgery. The latest searches were performed on 14 October 2022.
SELECTION CRITERIA
We included randomised controlled trials in adults (over 18 years, either with a diagnosis of coronary artery disease or cardiac valve disease, or who were candidates for cardiac surgery with the use of cardiopulmonary bypass), comparing corticosteroids with no treatments. There were no restrictions with respect to length of the follow-up period. All selected studies qualified for pooling of results for one or more endpoints.
DATA COLLECTION AND ANALYSIS
We used standard Cochrane methods. Our primary outcomes were all-cause mortality, and cardiac and pulmonary complications. Secondary outcomes were infectious complications, gastrointestinal bleeding, occurrence of new post-surgery atrial fibrillation, re-thoracotomy for bleeding, neurological complications, renal failure, inotropic support, postoperative bleeding, mechanical ventilation time, length of stays in the intensive care unit (ICU) and hospital, patient quality of life, and cost-effectiveness. We used GRADE to assess the certainty of evidence for each outcome.
MAIN RESULTS
This updated review includes 72 randomised trials with 17,282 participants (all 72 trials with 16,962 participants were included in data synthesis). Four trials (6%) were considered at low risk of bias in all the domains. The median age of participants included in the studies was 62.9 years. Study populations consisted mainly (89%) of low-risk, first-time coronary artery bypass grafting (CABG) or valve surgery. The use of perioperative corticosteroids may result in little to no difference in all-cause mortality (risk with corticosteroids: 25 to 36 per 1000 versus 33 per 1000 with placebo or no treatment; risk ratio (RR) 0.90, 95% confidence interval (CI) 0.75 to 1.07; 25 studies, 14,940 participants; low-certainty evidence). Corticosteroids may increase the risk of myocardial complications (68 to 86 per 1000) compared with placebo or no treatment (66 per 1000; RR 1.16, 95% CI 1.04 to 1.31; 25 studies, 14,766 participants; low-certainty evidence), and may reduce the risk of pulmonary complications (risk with corticosteroids: 61 to 77 per 1000 versus 78 per 1000 with placebo/no treatment; RR 0.88, 0.78 to 0.99; 18 studies, 13,549 participants; low-certainty evidence). Analyses of secondary endpoints showed that corticosteroids may reduce the incidence of infectious complications (risk with corticosteroids: 94 to 113 per 1000 versus 123 per 1000 with placebo/no treatment; RR 0.84, 95% CI 0.76 to 0.92; 28 studies, 14,771 participants; low-certainty evidence). Corticosteroids may result in little to no difference in incidence of gastrointestinal bleeding (risk with corticosteroids: 9 to 17 per 1000 versus 10 per 1000 with placebo/no treatment; RR 1.21, 95% CI 0.87 to 1.67; 6 studies, 12,533 participants; low-certainty evidence) and renal failure (risk with corticosteroids: 23 to 35 per 1000 versus 34 per 1000 with placebo/no treatment; RR 0.84, 95% CI 0.69 to 1.02; 13 studies, 12,799; low-certainty evidence). Corticosteroids may reduce the length of hospital stay, but the evidence is very uncertain (-0.5 days, 0.97 to 0.04 fewer days of length of hospital stay compared with placebo/no treatment; 25 studies, 1841 participants; very low-certainty evidence). The results from the two largest trials included in the review possibly skew the overall findings from the meta-analysis.
AUTHORS' CONCLUSIONS
A systematic review of trials evaluating the organ protective effects of corticosteroids in cardiac surgery demonstrated little or no treatment effect on mortality, gastrointestinal bleeding, and renal failure. There were opposing treatment effects on cardiac and pulmonary complications, with evidence that corticosteroids may increase cardiac complications but reduce pulmonary complications; however, the level of certainty for these estimates was low. There were minor benefits from corticosteroid therapy for infectious complications, but the evidence on hospital length of stay was very uncertain. The inconsistent treatment effects across different outcomes and the limited data on high-risk groups reduced the applicability of the findings. Further research should explore the role of these drugs in specific, vulnerable cohorts.

Meta-Analysis
BACKGROUND
Interventional percutaneous pulmonary valve implantation (PPVI) was first reported in 2000. Today, two different valves are certified for this procedure [i.e. Medtronic Melody valve (Medtronic, Dublin, Ireland) and Edwards Sapien™ valve (Edwards Lifesciences, Irvine, CA, USA)]. For a decade, studies have reported an increasing risk of infective endocarditis (IE) after PPVI; as patients for PPVI are usually younger, even a low annual incidence of IE is important. However, the overall incidence and potential differences between the valves remain unclear.
METHODS
A systematic literature search was performed in the databases Medline, Cochrane Library, and Embase including the clinical trials register. The aim was to summarize and compare the cumulative incidence of IE after PPVI. Using a sensitivity analysis we set the incidence rates of the two valve types in ratio with a normal population.
RESULTS
A total of 967 publications were identified searching for "pulmonary valve implantation," "PPVI," and 47 publications were used for final analysis. A total 3616 patients with Melody valves and 501 with Sapien™ valves were included. IE after PPVI occurred in 214 patients with Melody valves and in 5 patients only with Sapien™ valves. The pooled incidence for Melody and Sapien™ valves was 4.9% (95% CI: 3.6-6.2) and 1.3% (95% CI: 0.3-2.3), respectively. Chi-square test was significant. The sensitivity analysis showed that the incidence rate ratio was 252.1 (95% CI: 187.6-338.6) for Melody valves and for Sapien™ valves 2.7 (95% CI: 0.8-9.2).
CONCLUSIONS
At present, there is an important difference for the risk of IE after PPVI. To reduce the risk of post PPVI endocarditis, a careful valve selection in favor of the Sapien™ valves seems to be beneficial.

Meta-Analysis Review
QUESTION
Does preoperative intervention in people undergoing cardiac surgery reduce pulmonary complications, shorten length of stay in the intensive care unit (ICU) or hospital, or improve physical function?
DESIGN
Systematic review with meta-analysis of (quasi) randomised trials.
PARTICIPANTS
People undergoing coronary artery bypass grafts and/or valvular surgery.
INTERVENTION
Any intervention, such as education, inspiratory muscle training, exercise training or relaxation, delivered prior to surgery to prevent/reduce postoperative pulmonary complications or to hasten recovery of function.
OUTCOME MEASURES
Time to extubation, length of stay in ICU and hospital (reported in days). Postoperative pulmonary complications and physical function were measured as reported in the included trials.
RESULTS
The 17 eligible trials reported data on 2689 participants. Preoperative intervention significantly reduced the time to extubation (MD -0.14 days, 95% CI -0.26 to -0.01) and the relative risk of developing postoperative pulmonary complications (RR 0.39, 95% CI 0.23 to 0.66). However, it did not significantly affect the length of stay in ICU (MD -0.15 days, 95% CI -0.37 to 0.08) or hospital (MD -0.55 days, 95% CI -1.32 to 0.23), except among older participants (MD -1.32 days, 95% CI -2.36 to -0.28). When the preoperative interventions were separately analysed, inspiratory muscle training significantly reduced postoperative pulmonary complications and the length of stay in hospital. Trial quality ranged from good to poor and considerable heterogeneity was present in the study features. Other outcomes did not significantly differ.
CONCLUSION
For people undergoing cardiac surgery, preoperative intervention reduces the incidence of postoperative pulmonary complications and, in older patients, the length of stay in hospital.

BACKGROUND
Nonbacterial thrombotic endocarditis is characterized by the presence of organized thrombi on cardiac valves, often associated with hypercoagulable states. There is a paucity of data regarding the predictors of mortality in patients with nonbacterial thrombotic endocarditis. Our primary aim was to identify predictors of in-hospital mortality in patients with nonbacterial thrombotic endocarditis.
METHODS
A systematic literature review of all published cases and case series was performed until May 2018 according to Preferred Reporting Items for Systematic Review and Meta-analyses statement guidelines. We applied random forest machine learning model to identify predictors of in-patient mortality in patients with nonbacterial thrombotic endocarditis.
RESULTS
Our search generated a total of 163 patients (mean age, 46 ± 17 years; women, 69%) with newly diagnosed nonbacterial thrombotic endocarditis. The in-hospital mortality rate in the study cohort was 30%. Among the patients who died in the hospital, initial presentation of pulmonary embolism (12.2 vs. 2.6%), splenic (38.7 vs. 10.5%), and renal (40.8 vs. 9.6%) infarcts were higher compared to patients alive at the time of discharge. Higher rates of malignancy (71.4 vs. 39.4%, P = .0003) and lower rates of antiphospholipid syndrome (8.1 vs. 48.2%, P = .0001) were noted in deceased patients. Random forest machine learning analysis showed that older age, presence of antiphospholipid syndrome, splenic infarct, renal infarct, peripheral thromboembolism, pulmonary embolism, myocardial infarction, and mitral valve regurgitation were significantly associated with increased risk of in-hospital mortality.
CONCLUSION
Patients admitted with nonbacterial thrombotic endocarditis have a high rate of in-hospital mortality. Factors including older age, presence of antiphospholipid syndrome, splenic/renal infarct, lower limb thromboembolism, pulmonary embolism, myocardial infarction, and mitral valve regurgitation were significantly associated with increased risk of in-hospital mortality in patients with nonbacterial thrombotic endocarditis.

Meta-Analysis
Cryopreserved pulmonary homografts (PH) are the current gold standard for right ventricular outflow tract (RVOT) reconstruction in the Ross procedure. Unfortunately, their use is limited by a relatively scarce availability and high cost. Porcine stentless xenografts (SX) such as the Medtronic Freestyle SX are increasingly being used, although it is unclear whether the hemodynamic performance and the long-term durability are satisfactory. The present systematic review followed the Preferred Reporting Items for Systematic reviews and Meta-Analysis statement. The pooled treatment effects were calculated using a weighted DerSimonian-Laird random-effects model. We also evaluated the effect of time after RVOT reconstruction on valve gradients using meta-regression. Six studies with a total of 156 patients met the inclusion criteria. The pooled estimates for the pooled follow-up of 37 months were: 1.3% operative mortality, 94.8% overall survival, 7.5% structural valve deterioration, 5.2% reintervention, 73.3% asymptomatic, and 1.5% moderate or severe pulmonary insufficiency. Peak valve gradients were significantly correlated with time after RVOT, increasing during follow-up. Three studies compared PH with SX, one concluded that the SX is an acceptable alternative for RVOT reconstruction, whereas two concluded that this valvular substitute had inferior performance. The Freestyle SX can be considered as an alternative to PH, although it might be associated with more reinterventions, higher peak valve pressure gradients, and pulmonary valve dysfunction.

Review
Pulmonary hypertension (PH) is a classic pathophysiological consequence of left-sided valvular heart disease (VHD). However, as opposed to other forms of PH, there are relatively few published data on the prevalence, impact on outcome, and management of PH with VHD. The objective of this paper is to present a systematic review of PH in patients with VHD. PH is found in 15% to 60% of patients with VHD and is more frequent among symptomatic patients. PH is associated with higher risk of cardiac events under conservative management, during valve replacement or repair procedures, and even following successful corrective procedures. In addition to its usefulness in assessing the presence and severity of VHD, Doppler echocardiography is a key tool in diagnosis of PH and assessment of its repercussion on right ventricular function. Assessment of pulmonary arterial pressure during exercise stress echocardiography may provide additional prognostic information beyond resting evaluation. Cardiac magnetic resonance is also useful for assessing right ventricular geometry and function, which provide additional prognostic information in patients with VHD and PH.

INTRODUCTION
Nuchal Translucency (NT) is the sonographic form of subcutaneous gathering of liquid behind the foetal neck in the first trimester of pregnancy. There is association of increased NT with chromosomal and non-chromosomal abnormalities.
AIM
The purpose of this systemic review was to review the pregnancy outcome of abnormal nuchal translucency.
MATERIALS AND METHODS
The present systematic review was conducted by searching English language articles from sources such as International Medical Sciences, Medline, Web of science, Scopus, Google Scholar, PubMed, Index Copernicus, DOAJ, EBSCO-CINAHL. Persian articles were searched from Iranmedex and SID sources. Related key words were "outcome", "pregnancy", "abnormal", and "Nuchal Translucency" (NT). All, randomized, descriptive, analytic-descriptive, case control study conducted during 1997-2015 were included.
RESULTS
Including duplicate articles, 95 related articles were found. After reviewing article titles, 30 unrelated article and abstracts were removed, and 65 articles were evaluated of which 30 articles were duplicate. Finally 22 articles were selected for final analysis. Exclusion criteria were, case studies and reports and quasi experimental designs. This evaluation has optioned negative relationship between nuchal translucency and pregnancy result. Rate of cardiac, chromosomal and other defects are correlated with increased NT≥2.5mm. Cardiac disease which were associated to the increased NT are heart murmur, systolic organic murmur, Atrial Septal Defect (ASD), Ventricular Septal Defect (VSD), tricuspid valve insufficiency and pulmonary valve insufficiency, Inferior Vena Cava (IVC) and Patent Ductus Arteriosus (PDA). The most common problems that related with increased NT were allergic symptoms.
CONCLUSION
According to this systematic review, increased NT is associated with various foetal defects. To verify the presence of malformations, birth defect consultations with a perinatologist and additional tests are required.
