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.

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.

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.

Meta-Analysis
Because the real benefit of pulmonary valve replacement (PVR) in patients with repaired tetralogy of Fallot who develop pulmonary insufficiency remains unclear, it is necessary to analyze the evidence published around the world. We performed a systematic review of studies that reported data about the effect of PVR in patients with repaired tetralogy of Fallot that developed pulmonary insufficiency, until December 2012. The variables chosen to represent the benefit were both right ventricular (RV) and left ventricular measures, QRS duration, and functional class. The principal summary measures were difference in means with 95% confidence interval and p values (considered statistically significant when p < 0.05). The differences in means were combined across studies with the weighted DerSimonian-Laird random effects model. Meta-analysis, sensitivity analysis, and meta-regression were completed with the software Comprehensive Meta-Analysis (version 2, Biostat, Inc., Englewood, New Jersey). Forty-eight studies involving 3,118 patients met the eligibility criteria. The pooled 30-day mortality was 0.87% (47 studies; 27 of 3,100 patients); the pooled 5-year mortality was 2.2% (24 studies; 49 of 2,231 patients); the pooled 5-year re-PVR was 4.9% (15 studies; 88 of 1,798 patients). The results of this meta-analysis demonstrate that after PVR: 1) the RV experiences improvement of its volumes and function; 2) the left ventricle experiences improvement of its function; 3) QRS duration decreases; 4) symptoms improve; 5) pre-operative RV geometry modulates the effect of PVR; and 6) there is important heterogeneity of the effects among the studies, and few publication biases. In conclusion, PVR seems to be a positive approach in the analyzed scenario.

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.
