Meta-Analysis
BACKGROUND
Valve replacement surgery is the definitive management strategy for patients with severe valvular disease. However, valvular conduits currently in clinical use are associated with significant limitations. Tissue-engineered (decellularized) heart valves are alternative prostheses that have demonstrated promising early results. The purpose of this systematic review and meta-analysis is to perform robust evaluation of the clinical performance of decellularized heart valves implanted in either outflow tract position, in comparison with standard tissue conduits.
METHODS
Systematic searches were conducted in the PubMed, Scopus, and Web of Science databases for articles in which outcomes between decellularized heart valves surgically implanted within either outflow tract position of human subjects and standard tissue conduits were compared. Primary endpoints included postoperative mortality and reoperation rates. Meta-analysis was performed using a random-effects model via the Mantel-Haenszel method.
RESULTS
Seventeen articles were identified, of which 16 were included in the meta-analysis. In total, 1418 patients underwent outflow tract reconstructions with decellularized heart valves and 2725 patients received standard tissue conduits. Decellularized heart valves were produced from human pulmonary valves and implanted within the right ventricular outflow tract in all cases. Lower postoperative mortality (4.7% vs. 6.1%; RR 0.94, 95% CI: 0.60-1.47; P = 0.77) and reoperation rates (4.8% vs. 7.4%; RR 0.55, 95% CI: 0.36-0.84; P = 0.0057) were observed in patients with decellularized heart valves, although only reoperation rates were statistically significant. There was no statistically significant heterogeneity between the analyzed articles (I = 31%, P = 0.13 and I = 33%, P = 0.10 respectively).
CONCLUSIONS
Decellularized heart valves implanted within the right ventricular outflow tract have demonstrated significantly lower reoperation rates when compared to standard tissue conduits. However, in order to allow for more accurate conclusions about the clinical performance of decellularized heart valves to be made, there need to be more high-quality studies with greater consistency in the reporting of clinical outcomes.

Meta-Analysis
Impact of body mass index on procedural complications, procedure duration, and radiation dose in patients with atrial fibrillation undergoing radiofrequency ablation: A systematic review and meta-analysis.
BACKGROUND
The association of body mass index (BMI) and procedure-related factors in patients with atrial fibrillation (AF) after radiofrequency ablation (RFA) is still unclear.
HYPOTHESIS
BMI is associated with increased the radiation dose, procedure duration, and procedural complications.
METHODS
Prospective studies assessing BMI and procedure duration, radiation dose, and procedural complications in patients with AF after RFA were identified through electronic searches of PubMed, Embase, and the Cochrane Library database.
RESULTS
Ten studies with 14 735 participants undergoing RFA were included. Procedure duration was significantly longer in patients with overweight or obesity than in patients with normal BMI, with a mean difference (MD) of 0.95. Patients with overweight and obesity were exposed to a larger radiation dose, with standard MD of 1.71 and 1.98, respectively. There was no significant association between overweight or obesity and the risk of procedural complications (RR of 0.91 for overweight, 1.01 for obesity, 0.89 for stage I obesity, 1.00 for stage II obesity, and 0.94 for stage III obesity). Further analysis showed there was no significant difference regarding stroke or transient ischemic attack (overweight, RR: 0.92; obesity, RR: 1.02); cardiac tamponade (overweight, RR: 0.92; obesity, RR: 1.02); groin hematoma (overweight, RR: 0.62; obesity, RR: 0.40); or pulmonary vein stenosis (overweight, RR: 0.49; obesity, RR: 0.40) among BMI groups.
CONCLUSION
Based on available evidence, we first showed that patients with overweight/obesity undergoing RFA experienced a significantly increased procedure duration and received a larger radiation dose than patients with normal BMI; however, there was no significant difference in procedural complications between patients with overweight/obesity and patients with normal BMI.

Comparative Study Meta-Analysis
OBJECTIVES
Does the manipulation of the off-pump CABG (OPCAB) in patient with depressed left ventricular function is better than on-pump CABG (ONCAB) approach in in-hospital mortality and morbidities? Here we undertook a meta-analysis of the best evidence available on the comparison of primary and second clinical outcomes of the off-pump and on-pump CABG.
DESIGN
Systematic literature reviewer and meta-analysis.
DATA SOURCES
PubMed, EMBASE, Web of science and Cochrane Center Registry of Controlled Trials were searched the studies which comparing the use of the off-pump CABG(OPCAB) and on-pump CABG (ONCAB) for patients with LVD during January 1990.1 to January 2018.
ELIGIBILITY CRITERIA
All observation studies and randomized controlled trials comparing on-pump and off-pump as main technique for multi-vessel coronary artery disease (defined as severe stenosis (>70%) in at least 2 major diseased coronary arteries) with left ventricular dysfunction(defined as ejection fraction (EF) 40% or less) were included.
DATA EXTRACTION AND SYNTHESIS
Authors will screen and select the studies extract the following data, first author, year of publication, trial characters, study design, inclusion and exclusion criteria, graft type, clinical outcome, assess the risk of bias and heterogeneity. Study-specific estimates will pool through the modification of the Newcastle-Ottawa scale for the quality of study and while leave-one-out analysis will be used to detect the impact of individual studies on the robustness of outcomes.
RESULTS
Among the 987 screened articles, a total of 16 studies (32,354 patients) were included. A significant relationship between patient risk profile and benefits from OPCAB was found in terms of the 30-day mortality (odds ratio [OR], 0.84; 95% confidence interval [CI], 0.73-0.97; P = 0.02), stroke (OR, 0.69; 95% CI, 0.55-0.86; P = 0.00), myocardial infarction (MI) (OR, 0.71; 95% CI, 0.53-0.96; P = 0.02), renal failure (OR, 0.71; 95% CI, 0.55-0.93; P = 0.01), pulmonary complication (OR, 0.68; 95% CI, 0.52-0.90; P = 0.01), infection (OR, 0.67; 95% CI, 0.49-0.91; P = 0.00),postoperative transfusion (OR, 0.25; 95% CI, 0.08-0.84; P = 0.02) and reoperation for bleeding (OR, 0.56; 95% CI, 0.41-0.75; P = 0.00). There was no significant difference in atrial fibrillation (AF) (OR, 0.96;95%; CI, 0.78-1.41; P = 0.56) and neurological dysfunction (OR, 0.88; 95% CI, 0.49-1.57; P = 0.65).
CONCLUSIONS
Compared with the on-pump CABG with LVD, using the off-pump CABG is a better choice for patients with lower mortality, stroke, MI, RF, pulmonary complication, infection, postoperative transfusion and reoperation for bleeding. Further randomized studies are warranted to corroborate these observational data.

Review
Patients with achondroplasia and other causes of dwarfism suffer from increased rates of cardiovascular disease relative to the remainder of the population. Few studies have examined these patients when undergoing cardiac surgery or percutaneous intervention. This systematic review examines the literature to determine outcomes following cardiac intervention in this unique population. An electronic search was performed in the English literature to identify all reports of achondroplasia, dwarfism, and cardiac intervention. Of the 5,274 articles identified, 14 articles with 14 cases met inclusion criteria. Patient-level data was extracted and analyzed. Median patient age was 55.5 [interquartile ranges (IQR), 43.8, 59.8] years, median height 102.0 [98.8, 112.5] cm, median BMI 32.1 [27.0, 45.9], and 57.1% (8/14) were male. Of these 14 patients, nine had the following documented skeletal abnormalities: 66.7% (6/9) had scoliosis, 66.7% (6/9) had kyphosis, 11.1% (1/9) had lordosis, 11.1% (1/9) pectus carinatum and 11.1% (1/9) spinal stenosis. Coronary artery disease was present in 53.8% (7/13), and 30.8% (4/13) patients previously suffered a myocardial infarction. Of the eight patients who underwent cardiac surgery, 37.5% (3/8) underwent multivessel coronary artery bypass grafting, 37.5% (3/8) underwent aortic valve replacement, 25.0% (2/8) underwent type A aortic dissection repair, and the remaining 12.5% (1/8) underwent pulmonary thromboendarterectomy. Six patients underwent percutaneous intervention. Median cardiopulmonary bypass time was 136.5 [110.0, 178.8] minutes. Median arterial cannula size was 20.0 [20.0, 24.0] Fr. Bicaval cannulation was performed in all cases describing cannulation strategy (5/5). Median superior vena cava cannula size was 28.0 [28.0, 28.0] Fr, and inferior vena cava cannula size was 28.0 [28.0, 28.0] Fr. No mortality was reported with a median follow up time of 6.0 [6.0, 10.5] months. In conclusion, Common cardiac procedures can be performed with reasonable safety in this patient population. Operative adjustments may need to be made with respect to equipment to accommodate patient-specific needs.

BACKGROUND
Minimally invasive esophagectomy (MIE) is increasingly accepted in many countries. McKeown esophagectomy and Ivor Lewis esophagectomy are two protocols commonly used for MIE, but which one provides more benefit to the patients remains matter of controversy.
METHODS
All records in PubMed, Embase, Medline, The Cochrane Library, Wanfang Database, China National Knowledge Infrastructure (CNKI) and Chinese VIP Information till May 2019 were systematically retrieved to compare the cohort studies of McKeown esophagectomy and Ivor Lewis esophagectomy. A meta-analysis of the extracted data was performed using the Review Manager 5.3 and Stata 15 software.
RESULTS
The meta-analysis included 23 cohort studies in which a total of 4,933 patients were enrolled. The results revealed that minimally invasive McKeown esophagectomy (MIME) was superior to minimally invasive Ivor Lewis esophagectomy (MILE) in hospital cost, but inferior to it in operating time, length of hospital stay, in-hospital mortality, 30-day mortality, 90-day mortality, anastomotic leakage, anastomotic leakage requiring surgery, anastomotic stenosis, recurrent laryngeal nerve (RLN) injury, chylothorax, pulmonary complications and total complications. There were no statistical differences between MIME and MILE in blood loss, detected number of lymph nodes, blood transfusion rate, R0 resection rate, re-operation rate, drainage duration, length of the stay in intensive care unit (ICU), 1-year mortality, lung infection, cardiac arrhythmia and delayed gastric emptying.
CONCLUSIONS
Except for the cost, MILE is superior to MIME in several aspects, and may represent a better choice for MIE. The results of the present study should be interpreted with caution since the meta-analysis is based on nonrandom cohort studies which may have a selection bias.

Review
Fibrosing mediastinitis (FM) is a very rare disease, often caused by histoplasmosis capsulatum, tuberculosis, sarcoidosis, autoimmunity and other diseases, such as IgG 4-related diseases. Fibrous structures in the mediastinum compress the pulmonary artery, pulmonary vein, superior vena cava, esophagus, trachea and cardiac vessels, leading to clinical symptoms. Drug therapeutic modality for pulmonary vein stenosis (PVS) caused by FM is palliative in essence and with limited efficacy, whereas surgical treatment causes high mortality. In recent years, catheter-based treatment to FM-caused PVS has emerged as a promising therapeutic modality, however, the safety and effectiveness of this modality remain unclear. Therefore, a systematic review on the safety and efficacy of the catheter-based treatment for PVS caused by FM was performed, in the hope to shed lights on the alternative therapeutic strategy to this fatal disease.

Meta-Analysis
AIMS
Patients in cardiogenic shock (CS) due to decompensated aortic stenosis (AS) evidence poor prognosis. Both emergency transcatheter aortic valve replacement (eTAVR) and emergency balloon aortic valvuloplasty (eBAV) have been reported in CS patients. We aimed to summarize and compare available studies on eBAV and eTAVR in patients suffering from CS due to decompensated AS with regard to safety and efficacy.
METHODS AND RESULTS
Study-level data were analyzed. Heterogeneity was assessed using the I2 statistic. Pooled proportions, ie, event rates, were calculated and obtained using a random-effects model (DerSimonian and Laird). Eight studies were found suitable for the final analysis, including 311 patients. Primary endpoint was mortality at 30 days. For eBAV (n = 238), 30-day mortality rate was 46.2% (95% confidence interval [CI], 30.3%-62.5%; I²=74%), major bleeding rate was 10% (95% CI, 5.4%-15.7%; I²=13%), and stroke rate was 0.7% (95% CI, 0.0%-2.7%; I²=0%). Aortic regurgitation (AR) ≥II was present in 8.6% (95% CI, 0.4%-23.5%; I²=86%). For eTAVR (n = 73), 30-day mortality rate was 22.6% (95% CI, 12.0%-35.2%; I²=26%), major bleeding rate was 5.8% (95% CI, 0.5%-14.7%; I²=0%), and stroke rate was 5.8% (95% CI, 0.5%-14.7%; I²=0%). AR ≥II was present in 4% (95% CI, 0.0%-12.1%; I²=0%).
CONCLUSION
Mortality in CS patients due to decompensated severe AS is high, regardless of interventional treatment strategy. Both eBAV and eTAVR seem feasible. As eTAVR is associated with better initial improvements in hemodynamics and simultaneously avoids sequential interventions, it might be favorable to eBAV in select patients. If eTAVR is not available, eBAV might serve as a "bridge" to elective TAVR.

Review
There is a lack of consensus regarding the preoperative pulmonary valve (PV) -score "cut-off" in tetralogy of Fallot (ToF) patients to attempt a successful valve sparing surgery (VSS). Therefore, the aim of this study was to review the available evidence regarding the association between preoperative PV -score and rate of re-intervention for residual right ventricular outflow tract (RVOT) obstruction, i.e. successful valve sparing surgery. A systematic search of studies reporting outcomes of VSS for ToF was performed utilizing PubMed, EMBASE, and Scopus databases. Patients with ToF variants such as pulmonary atresia, major aortopulmonary collaterals, absent pulmonary valve, associated atrioventricular septal defect, and discontinuous pulmonary arteries were excluded. Out of 712 screened publications, 15 studies met inclusion criteria. A total of 1091 patients had surgery at a median age and weight of 6.9 months and 7.2 kg, respectively. VSS was performed on the basis of intraoperative PV assessment in 14 out of 15 studies. The median preoperative PV -score was -1.7 (0 to -4.9) with a median re-intervention rate of 4.7% (0-36.8%) during a median follow-up of 2.83 years (1.4-15.8 years). Quantitatively, there was no correlation between decreasing preoperative PV -scores and increasing RVOT re-intervention rates with a correlation coefficient of -0.03 and an associated -value of 0.91. In observational studies, VSS for ToF repair was based on intraoperative evaluation and sizing of the PV following complete relief of all levels of obstruction of the RVOT, rather than pre-operative echocardiography derived PV -scores.

BACKGROUND
Immunoglobulin G4-related disease (IgG4-RD) is a recently recognized, immune-mediated chronic fibrotic inflammation that can involve almost all organs, causing tumefaction and dysfunction. Its presence in pulmonary circulation is underestimated and has not yet been investigated.
OBJECTIVES
We describe a representative IgG4-RD patient with pulmonary artery stenosis and pulmonary embolism, leading to reversible pulmonary hypertension. Literature review of IgG4-RD with pulmonary circulation involvement was conducted.
DATA SOURCES
References for this review were identified through searches via PubMed, EBSCO, and Web of Science for published articles before November 2016.
RESULTS
There were 15 published cases of IgG4-RD with pulmonary vascular involvement, 3 with pulmonary arteritis, 2 with pulmonary artery aneurysm, 3 with pulmonary artery stenosis, 1 with obliterative phlebitis, and 1 with pulmonary embolism. Possible immunity and inflammation mechanisms were summarized.
CONCLUSIONS
IgG4-RD with pulmonary vascular involvement is rare. Echocardiogram and contrast-enhanced chest CT are helpful to screen the disease. Clinical manifestations were found from asymptomatic to dyspnea or even syncope. And nearly all cases had more than 1 organ affected, with significantly increased serum IgG4 levels. PET/CT aided in identifying affected organs and determining candidate biopsy sites. More awareness is urged to evaluate the pulmonary vascular manifestations of this disease.

Echocardiography is the mainstay in screening for pulmonary hypertension (PH). International guidelines suggest echocardiographic parameters for suspecting PH, but these may not apply to many adults with congenital heart disease (ACHD). PH is relatively common in ACHD patients and can significantly affect their exercise capacity, quality of life, and prognosis. Identification of patients who have developed PH and who may benefit from further investigations (including cardiac catheterization) and treatment is thus extremely important. A systematic review and survey of experts from the United Kingdom and Ireland were performed to assess current knowledge and practice on echocardiographic screening for PH in ACHD. This paper presents the findings of the review and expert statements on the optimal approaches when using echocardiography to assess ACHD patients for PH, with particular focus on major subgroups: patients with right ventricular outflow tract obstruction, patients with systemic right ventricles, patients with unrepaired univentricular circulation, and patients with tetralogy of Fallot with pulmonary atresia.
