To investigate if mitral valve (MV) surgery quality differs by hospital volume in New Jersey (NJ). Methods. Using the NJ State Inpatient Database, patients ≥18 years undergoing MV repair or replacement from 2016–2019 were identified. Centers were considered high-volume if they performed more than 50 mitral operations annually. Baseline characteristics and outcomes (in-hospital mortality, seven-day readmission, hospital length of stay (LOS), and postoperative complications) were evaluated for the population and by center volume. Subanalysis by center volume within each procedure was conducted. Results. Among 2,560 mitral operations, MV replacement (92.3% (n = 2,362)) was performed more often than repair. High- (4) and low-volume (15) centers performed 1,180 (46.1%) and 1,380 (53.9%) mitral surgeries, respectively. Charlson Comorbidity Indices did not differ by center volume, including in subgroup analyses. Low-volume centers had higher rates of Hispanic patients, low-income patients, and readmission rates. High-volume centers had more transfers, urgent/emergent admissions, higher rates of in-hospital mortality, and longer LOS. Postoperative complications did not differ by volume. The MV replacement cohort reflected many of the differences seen in the total population, in addition to seeing higher rates of heart failure at high-volume centers and stroke at low-volume centers. Within MV repairs, significantly more Hispanic patients presented to low-volume centers and high-volume centers had longer LOS. Multivariable analysis indicated that hospital volume was not correlated to in-hospital mortality for the total population and within each procedure. Conclusions. MV replacement is performed more frequently than repair. Hospital volume is not correlated with MV surgical quality, and more representative quality measures are needed.","PeriodicalId":15367,"journal":{"name":"Journal of Cardiac Surgery","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2023-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44832517","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Tricuspid valve (TV) disease is substantially less common than mitral or aortic valve disease, and it is commonly missed due to the tolerability of stenosis or regurgitation. Adults seldom have primary tricuspid valve regurgitation, which is linked to rheumatic heart disease, infectious endocarditis, myxomatous valve disease, congenital heart disease, carcinoid syndrome, and/or infiltrative valvopathy. Materials and Methods. The authors examined the Valve Surgery Data Bank retrospectively to identify all patients who underwent TV replacement without concomitant surgeries between 2004 and 2014. In addition, the exclusion criteria suggested that all instances involving solitary valve repair were eliminated. Through visits or phone interviews, long-term follow-up was collected through the end of June 2022 in order to gather information on postoperative occurrences among the patients. The average follow-up time was 10.7 + 2.1 (5–15) years. Results. The overall survival rate was 90.9%.

The effects of sex on the prognosis of patients with acute type A aortic dissection (ATAAD) have still remained controversial. This study aimed to explore the sex differences in outcomes of ATAAD patients undergoing surgery. Methods. Data of patients with ATAAD who were operated in our center from 2010 to 2018 were retrospectively collected. Data on pre-, intra-, and postoperative courses were analyzed. Propensity score weighting was performed to balance the baseline characteristics. Multivariable logistic regression was used to assess predictors of early mortality in overall female and male patients. Results. A total of 1448 patients were enrolled, including 352 (24.3%) female patients and 1096 (75.7%) male patients.

In the Norwood procedure, a conduit is performed either from the subclavian artery to the pulmonary artery, Blalock–Taussig shunt (mBTs), or from the right ventricle to the pulmonary artery (RV-PA shunt). There are some concerns regarding the two shunts and which one is better according to morbidity and mortality in patients with hypoplastic left heart syndrome or its variants. Methods. We systematically searched PubMed, Web of Science, Scopus, Embase, and Cochrane Library databases from inception to 04/June/2021 to collect articles reporting a comparison of RV-PA shunt and mBTs. Results. Our meta-analysis showed that the mortality rate after 6 months, 1, 2, 3, 4, 5, and 6 years for the mBTS group was 16.3%, 28.6%, 34.8%, 42.4%, 44.6%, 45.1%, and 39.6%, respectively, and for the RV-PAS, 14.8%, 26.6%, 31%, 40.1%, 36.1%, 37.5%, and 34.0%, respectively. The mortality rate was significantly higher in the mBTs group at 1 and 2 years; otherwise, there is no significance differences. Overall complications rate was higher in the mBTs group than in the RV-PAs group (17.8% vs. 8.5%). In contrast, the rate of cardiac complications was higher in the RV-PAS group. Conclusions. The RV-PA shunt had lower mortality and overall complications rate than mBT shunt at the short-term outcome within the first two years, but at the long term, there was no difference between the two shunts. On the other hand, the mBT shunt had a lower incidence of cardiac complications at the early stage after the operations. However, some studies are poor due to the difficulties in conducting original research in this field. Therefore, we recommend conducting systematic reviews and original studies to compare these and other therapeutic procedures for these patients.","PeriodicalId":15367,"journal":{"name":"Journal of Cardiac Surgery","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2023-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42976913","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The optimal cerebral protection strategy in acute type A aortic dissection (ATAAD) is still without a clear consensus. The purpose of this meta-analysis was to compare the outcome of different cerebral protection strategies on ATAAD patients. Materials and Methods. We conducted a systematic review including all studies concerning surgically managed ATAAD patients between 1.1.2010 and 28.2.2022 and reporting the use of cerebral protection strategies in three large databases (Pubmed, Cochrane library, and Scopus). The main outcome events were 30-day mortality and a postoperative stroke rate. The pooled event rates adjusted by age, gender, CPB duration, circulatory arrest duration, and total arch reconstruction rate were calculated. Results. Overall, 39 articles were included covering a total of 16, 876 ATAAD patients. The estimated adjusted pooled early mortality rate was 10.1% (95% confidence interval [CI] 9.1–11.3%) in the ACP group, 15.9% (13.3–18.9%) in the RCP group, and 11.6% (9.2–14.5%) in the HCA group.

The tricuspid anterior leaflet is considered important in most repair techniques for Ebstein anomaly (EA). We aim to assess the anterior leaflet morphology using novel metrics and investigate the association of the morphology with recurrent moderately severe or greater tricuspid regurgitation (TR). Methods. Seventy-four paediatric patients with EA undergoing cone reconstruction (CR) between 2010 and 2021 were included. Anterior leaflet mobility (ALM) and anterior leaflet length (ALL) were remeasured on preoperative 2D echocardiography. The prediction accuracies of ALM and ALL-I (ALL indexed to body surface area) for recurrent TR were evaluated using receiver operating characteristic (ROC) curve analyses. Results. The median age of patients was 3.3 years (interquartile range, 1.9–7.1 years). Both ALM and ALL-I correlated with the Carpentier type and GOSH score. Nine patients (12.2%) developed recurrent TR during the one-year follow-up. By univariable logistic regression analyses, ALM (odds ratio [OR], 0.89; 95% CI [confidence interval], 0.82–0.96; \u0000 \u0000 p\u0000 \u0000  = 0.003) and ALL-I (OR, 1.39; 95% CI, 1.08–1.78; \u0000 \u0000 p\u0000 \u0000  = 0.011) were risk factors for recurrent TR.

Heart transplantation (HT) is a definitive therapy for refractory heart failure, making it the gold-standard treatment for recipients with end-stage disease. Heart allocation policy (HAP) in the United States was changed on October 18th, 2018. The aim of this study was to assess the effect of the new policy on racial disparities in heart transplantation (HT) outcomes. Methods. The United Network for Organ Sharing (UNOS) registry was used to identify adult recipients undergoing isolated HT between 2010 and 2021. Recipients were stratified into pre-HAP (January 2010 to September 2018) vs. post-HAP (October 2018 to September 2021). Recipient race was classified as White, Black, Hispanic, or other. The primary outcome was post-HT mortality. Cox proportional hazard models were used for risk-adjustment in evaluating the independent effect of race on post-HT mortality. Results. A total of 27,403 recipients underwent HT in 143 centers during study period. The proportion of non-Whites undergoing HT increased in the post-HAP era: (pre-HAP: White 66.0%, Black 21.2%, Hispanic 8.2%, Other 4.6% versus post-HAP: White 62.5%, Black 23.2%, Hispanic 9.5%, Other 4.8%; \u0000 \u0000 p\u0000 <\u0000 0.001\u0000 \u0000 ).
