Minimally invasive mitral valve repair (MIMVR) has been demonstrated to be safe and effective, but technical difficulty, outcome variation, and lack of standardized protocols undermine the utility of artificial chordae. This study aims to analyze the midterm outcomes of repair using artificial chordae through right minithoracotomy. Methods. A retrospective cohort study was conducted on consecutive patients who underwent MIMVR using artificial chordae at a single center in Vietnam between April 2016 and April 2022. Valve repairs were separated into two groups based on a previously validated complexity score: simple repair (Group 1) and intermediate-to-complex repair (Group 2). Demographic variables, comorbidities, operative characteristics, surgical outcomes, and follow-up data on survival and mitral regurgitation (MR) grade were analyzed. The learning curve was assessed by comparing the number of procedures with operation time and aorta cross-clamp time. Primary endpoints included survival and freedom from recurrent MR at four years. Results. Ninety patients were identified, including 41 simple and 49 intermediate-to-complex repairs. The mean age was 50.5 ± 12.9 years. Both groups had similar preoperative characteristics. The perioperative and postoperative outcomes were favorable, with no cases requiring mitral valve replacement. The median follow-up time was 30.3 months (18.2–40.4), and there were two (2.2%) cardiac deaths, with one in each group. The Kaplan–Meier survival estimates for Groups 1 and 2 at 12 and 24 months were 97% vs. 100% and 97% vs. 96%, respectively (95% CI = 0.05–12.2, \u0000 \u0000 P\u0000 =\u0000 0.850\u0000 \u0000 ), and estimates for freedom from recurrent MR were 97% vs. 92% and 97% vs. 88%, respectively (95% CI = 0.49–12.0, \u0000 \u0000 P\u0000 =\u0000 0.260\u0000 \u0000 ). There was a negative association between the volume of operations and the duration of operation and aortic cross-clamp time, leading to shorter durations. Conclusion. Based on our single-center experience, MIMVR using artificial chordae via right mini-thoracotomy can be safely and effectively performed in resource-limited countries for patients with MR. This approach has been shown to be applicable for a range of MR complexities, from simple to intermediate-to-complex MV repairs, and has demonstrated promising results in terms of midterm freedom from MR recurrence.","PeriodicalId":15367,"journal":{"name":"Journal of Cardiac Surgery","volume":"60 25","pages":""},"PeriodicalIF":1.6,"publicationDate":"2023-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138595115","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}

Limited randomized controlled studies showed that thoracoscopic surgical left atrial ablation was not superior to catheter ablation (CA) in patients with persistent atrial fibrillation (PerAF). Right atrium might play an important role in triggering and maintaining atrial fibrillation (AF) in patients with PerAF. This study aimed to compare the efficacy of thoracoscopic surgical biatrial ablation versus CA in patients with PerAF. Methods. Patients with PerAF underwent thoracoscopic surgical biatrial ablation or CA were included in this study. Propensity score matching (1 : 2) was applied to select patients in CA group and surgical ablation (SA) group. The primary endpoint was to compare the probability of freedom from atrial tachyarrhythmias between SA and CA. Atrial tachyarrhythmia recurrence was defined as any atrial tachyarrhythmias longer than 30 s documented by 24-hour Holter monitoring after the 3-month blanking period. Results. After propensity score matching, 51 patients in surgical biatrial ablation group and 102 patients in CA group were enrolled (mean left atrial diameter: 45.8 mm). The probability of freedom from atrial tachyarrhythmias on antiarrhythmia drugs was 62.7%, 60.6%, and 60.6% in SA group and 42.0%, 39.6%, and 36.7% in CA group at 12, 24, and 36 months, respectively ( p  = 0.011), and off antiarrhythmia drugs were 56.9%, 52.5%, and 52.5% in SA group and 36.0%, 31.4%, and 27.5% in CA group at 12, 24, and 36 months, respectively ( p  = 0.007). After adjustment of age, sex, left atrial diameter, and AF duration history, multivariable Cox regression analysis suggested that SA procedure was an independent factor to reduce the risk of atrial tachyarrhythmia recurrence (HR: 0.589, 95% CI 0.370–0.937, p  = 0.025).

The present study sought to characterize the pulmonary arterial morphology and pulmonary blood supply in patients of tetralogy of Fallot and pulmonary atresia (TOF-PA) on CT angiography. Materials and Methods. We retrospectively reviewed our departmental database to identify patients with TOF-PA evaluated using CT angiography. The images were analysed to detect the presence of main and branch pulmonary arteries and pulmonary arterial confluence, presence of major aortopulmonary collateral arteries (MAPCAs), laterality and relation with pulmonary arterial morphology, and presence of patent arterial duct and associated intra- and extracardiac anomalies. Results. TOF-PA was identified in 177 patients (114 (64.4%) males; median age: 9 months). Pulmonary arteries were confluent in 142/177 (80.2%) patients. According to Somerville classification, type II pulmonary atresia was the most frequent pattern seen in 127/177 (71.8%). Based on McGoon’s ratio, pulmonary arteries were adequate for surgery in 123/177 (69.5%) patients. Patent arterial duct was present in 84/177 (47.5%) patients while MAPCAs were present in 124 (70.1%) patients, of which 72/124 (58.1%) patients had at least 1 essential MAPCA supplying either lung. According to Congenital Heart Surgeons’ Society classification, type B pulmonary arterial anatomy was the most prevalent, seen in 103/177 (57.6%) patients. Conclusion. TOF-PA is associated with marked morphologic variability in the pulmonary arterial arborization to supply the lungs. Cardiac CT angiography can accurately delineate the pulmonary arterial morphology, sources of pulmonary blood supply, and associated cardiovascular anomalies in patients with TOF-PA which aids in planning appropriate surgical management including decisions regarding the need for unifocalization of MAPCAs.","PeriodicalId":15367,"journal":{"name":"Journal of Cardiac Surgery","volume":"59 9","pages":""},"PeriodicalIF":1.6,"publicationDate":"2023-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139275130","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 aim of this study is to investigate the predictive value of fetal and neonatal echocardiographic parameters for neonatal coarctation repair in fetuses suspected of coarctation of the aorta (CoA), establish a prediction model for neonatal coarctation repair, and verify its predictive effectiveness and clinical applicability. Methods. From September 2017 to September 2022, fetuses suspected with CoA were enrolled. They were divided into two groups based on the need for neonatal coarctation repair. Fetal and neonatal echocardiographic parameters and clinical characteristics were collected retrospectively. Univariate and multivariate logistic regressions were applied to select significant predictors, which were further used to establish the nomogram prediction model. The area under the curve (AUC) of the receiver operating characteristic (ROC) was employed to quantify its discrimination ability. The calibration curve was drawn for internal verification, and the decision curve analysis (DCA) and clinical impact curve (CIC) were used to evaluate the clinical applicability of the prediction model. Results. This study included 50 infants suspected of CoA prenatally, of which 16 (32%) received aortic coarctation repair in the neonatal period and 34 (68%) did not. Multivariable logistic regression analysis revealed that the fetal echocardiographic parameter aortic isthmus/ductus arteriosus (AoI/DA) diameter ratio and the neonatal echocardiographic parameters such as the distance from left common carotid to left subclavian artery (LCSA) and the diameter of distal transverse aortic arch (DTAA) were independent predictors for neonatal coarctation repair. The ROC curve of the model showed excellent predictive value (AUC = 0.943). The calibration curve of the prediction model exhibited good fitness. The DCA and CIC demonstrated that the model had good clinical utility. Conclusion. The prediction model, which combines the fetal echocardiographic parameter AoI/DA diameter ratio and the neonatal echocardiographic parameters distance of LCSA and DTAA diameter, has an exceptional level of clinical value and prediction accuracy.","PeriodicalId":15367,"journal":{"name":"Journal of Cardiac Surgery","volume":" 37","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135340500","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 aim of this study was to clarify the incidence and risk factors for acute kidney injury (AKI) in patients undergoing hemiarch replacement (HAR) under moderate hypothermic circulatory arrest (MHCA) with retrograde cerebral perfusion (RCP). Methods. We retrospectively analyzed patients who underwent HAR under MHCA with RCP at our institution between April 2015 and July 2022. Exclusion criteria were preoperative dialysis, single kidney, and lack of preoperative plasma creatinine data. The study endpoint was the incidence of postoperative AKI, defined using the Kidney Disease: Improving Global Outcomes criteria. Multivariate logistic regression analysis was performed to identify the risk factors for postoperative AKI. Results. One hundred and seventy-nine patients were included in this study. The most common indications for HAR were thoracic aortic aneurysm (n = 107) and acute aortic dissection (n = 57). Concomitant procedures, most frequently aortic valve surgery, were performed in 104 (60.5%) patients. Median circulatory arrest time and minimum rectal temperature were 15 minutes (interquartile range, 11 to 19) and 27.4°C (interquartile range, 25.9 to 28.1), respectively. Operative mortality was 1.1%. The incidence of postoperative AKI was 37.8%.

We aimed to investigate outcomes in transcatheter versus surgical mitral valve repair in patients with secondary mitral regurgitation (MR) by leveraging a global, multi-institutional federated network database. Methods. Using validated ICD-10 and CPT codes, the TriNetX Analytics Research Data Network (a global federated database of electronic health records from 58 healthcare organizations) was queried to identify patients diagnosed with chronic, severe, ischemic MR and undergoing either transcatheter mitral valve repair (TMVr) or surgical mitral valve repair (SMVr) between January 1, 2015 and December 31, 2020. To adjust for baseline differences, 1 : 1 propensity score matching was performed via logistic regression using the nearest-neighbor approach and matching for 29 covariates including demographics, comorbidities, surgical history, preoperative medications, left ventricular function and heart failure status.

When compared to TMVr, patients undergoing SMVr were significantly less likely to undergo mitral valve reintervention at 3 years (HR: 0.29, 95% CI: 0.14–0.58, p = 0.0002). Conclusion. In a real-world, propensity score matching analysis of a large cohort of patients with chronic ischemic MR, surgical mitral valve repair had significantly better survival rates and significantly lower reintervention rates at 1- and 3-years compared to TMVr.","PeriodicalId":15367,"journal":{"name":"Journal of Cardiac Surgery","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135346113","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}
