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.

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
AIMS
To undertake a systematic review and meta-analysis to determine the influence of tricuspid regurgitation (TR) severity on mortality.
METHODS AND RESULTS
We performed a systematic search for studies reporting clinical outcomes of patients with TR. The primary endpoint was all-cause mortality and secondary endpoints were cardiac mortality and hospitalization for heart failure (HF). Overall risk ratios (RR) and 95% confidence intervals (CIs) were derived for each endpoint according to the severity of TR by meta-analysing the effect estimates of eligible studies. Seventy studies totalling 32 601 patients were included in the analysis, with a mean (±SD) follow-up of 3.2 ± 2.1 years. Moderate/severe TR was associated with a two-fold increased mortality risk compared to no/mild TR (RR 1.95, 95% CI 1.75-2.17). Moderate/severe TR remained associated with higher all-cause mortality among 13 studies which adjusted for systolic pulmonary arterial pressures (RR 1.85, 95% CI 1.44-2.39), and 15 studies, which adjusted for right ventricular (RV) dysfunction (RR 1.78, 95% CI 1.49-2.13). Moderate/severe TR was also associated with increased cardiac mortality (RR 2.56, 95% CI 1.84-3.55) and HF hospitalization (RR 1.73, 95% CI 1.14-2.62). Compared to patients with no TR, patients with mild, moderate, and severe TR had a progressively increased risk of all-cause mortality (RR 1.25, 1.61, and 3.44, respectively; P < 0.001 for trend).
CONCLUSIONS
Moderate/severe TR is associated with an increased mortality risk, which appears to be independent of pulmonary pressures and RV 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.

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.

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
BACKGROUND
Reported long-term outcome measures vary greatly between studies in Fontan patients making comprehensive appraisal of mortality hazard challenging. We sought to create a clinical risk score to assist monitoring of Fontan patients in the outpatient setting.
METHODS
A systematic review was conducted to evaluate risk factors for long-term (beyond the first postoperative year) mortality in Fontan patients. Studies were eligible for inclusion if ≥90 patients were included or ≥20 long-term mortalities we reported. Risk factors for long-term mortality were determined. The pooled hazard ratios were used to create components of a clinical score for long-term mortality using meta-analysis techniques.
RESULTS
Twenty-eight studies were included. The total number of patients was 6707 with an average follow-up of 8.23 ± 5.42 years. There were 1000 deaths. Thirty-five risk factors for late mortality were identified and classified into 9 categories and their relative hazards were used to derive the initial components of a weighted, practical and clinically based Fontan risk score (ranging from 0 to 100). The final score included 8 risk factors: anatomic risk factors, elevated preoperative pulmonary artery pressure, atriopulmonary Fontan, heart failure symptoms, arrhythmia, moderate/severe ventricular dysfunction or atrioventricular valve regurgitation, protein losing enteropathy, and end organ disease (cirrhosis or renal insufficiency).
CONCLUSION
In patients with Fontan circulation, the influence of readily available risk factors can be quantified in an integer score to predict long-term mortality. Prospective validation and refinement of this risk score will be undertaken.

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.

WHAT IS KNOWN AND OBJECTIVE
Direct oral anticoagulants (DOACs) are increasingly prescribed instead of warfarin for chronic anticoagulation for ease of dosing, fewer interactions, and less stringent monitoring. However, it is important to consider indications and comorbidities for which warfarin is still the preferred anticoagulant. This review aims to capture these clinical scenarios in which warfarin may still be preferred over DOACs.
METHODS
We undertook a comprehensive literature search using the PubMed database. Key search terms were based on DOAC clinical trial exclusion criteria, as well as indications and conditions in which the use of DOACs for anticoagulation has suggested harm. Society guidelines and tertiary literature were used to inform expert opinion where necessary. Studies were included if they investigated the use of DOACs or warfarin in the identified indications or conditions.
RESULTS AND DISCUSSION
Currently, evidence for the use of warfarin over DOACs for anticoagulation is strongest for patients with prosthetic valves, antiphospholipid syndrome, or a high risk of gastrointestinal bleeding. For several clinical situations, including mitral stenosis, obesity, altered gastrointestinal anatomy, pulmonary arterial hypertension, renal or hepatic impairment, and left ventricular thrombus, evidence is lacking but may eventually support the use of DOACs. Depending on indication and condition, appropriateness of DOAC use may vary by agent.
WHAT IS NEW AND CONCLUSION
New evidence continues to support new indications and conditions in which DOACs may be appropriate to use for anticoagulation. There are key clinical scenarios, however, in which emerging literature continues to support warfarin as the preferred anticoagulant.

Meta-Analysis
BACKGROUND
The aim of this study was to investigate long-term survival, clinical status, and echocardiographic findings of patients with severe functional mitral regurgitation (FMR) undergoing MitraClip (MC) treatment and to explore the role of baseline features on outcome. Methods and Results: Randomized and observational studies of FMR patients undergoing MC treatment were collected to evaluate the overall survival, New York Heart Association (NYHA) class and echocardiographic changes after MC treatment. Baseline parameters associated with mortality and echocardiographic changes were also investigated. Across 23 studies enrolling 3,253 patients, the inhospital death rate was 2.31%, whereas the mortality rate was 5.37% at 1 month, 11.87% at 6 months, 18.47% at 1 year and 31.08% at 2 years. Mitral regurgitation Grade <3+ was observed in 92.76% patients at discharge and in 83.36% patients at follow-up. At follow-up, 76.63% of patients NYHA Class I-II and there were significant improvements in left ventricular (LV) volume, ejection fraction, and pulmonary pressure. Atrial fibrillation (AF) had a significant negative effect on 1-year survival (β=0.18±0.06; P=0.0047) and on the reduction in LV end-diastolic and end-systolic volumes (β=-1.05±0.47 [P=0.0248] and β=-2.60±0.53 [P=0.0024], respectively).
CONCLUSIONS
MC results in durable reductions in mitral regurgitation associated with significant clinical and echocardiographic improvements in heart failure patients. AF negatively affects LV reverse remodeling and 1-year survival after MC treatment.
