| 19 | Safety and efficacy of balloon angioplasty compared to stent-basedstrategies with pulmonary vein stenosis:A systematic review and meta-analysis显示文摘BACKGROUND Pulmonary vein stenosis(PVS)is an uncommon but known cause of morbidity and mortality in adults and children and can be managed with percutaneous revascularization strategies of pulmonary vein balloon angioplasty(PBA)or pulmonary vein stent implantation(PSI).AIM To study the safety and efficacy outcomes of PBA vs PSI in all patient categories with PVS.METHODS We performed a literature search of all studies comparing outcomes of patients evaluated by PBA vs PSI for PVS.We selected all published studies comparing PBA vs PSI for PVS with reported outcomes of restenosis and procedure-related complications in all patient categories.In adults,PVS following atrial fibrillation ablation and in children PVS related to congenital etiology or post-procedural PVS following total or partial anomalous pulmonary venous return repair were included.The patient-centered outcomes were risk of restenosis requiring re-intervention and procedural-related complications.The metaanalysis was performed by computing odds ratios(ORs)using the random effects model based on underlying statistical heterogeneity.RESULTS Eight observational studies treating 768 severe PVS in 487 patients met our inclusion criteria.The age range of patients was 6 months to 70 years and 67%were males.The primary outcome of the re-stenosis requiring re-intervention occurred in 196 of 325 veins in the PBA group and 111 of 443 veins in the PSI group.Compared to PSI,PBA was associated with a significantly increased risk of re-stenosis(OR 2.91,95%CI:1.15-7.37,P=0.025,I2=79.2%).Secondary outcomes of the procedurerelated complications occurred in 7 of 122 patients in the PBA group and 6 of 69 in the PSI group.There were no statistically significant differences in the safety outcomes between the two groups(OR:0.94,95%CI:0.23-3.76,P=0.929,I^(2)=0.0%).CONCLUSION Across all patient categories with PVS,PSI is associated with reduced risk of re-intervention and is as safe as PBA and should be considered first-line therapy for PVS. | Pradyumna Agasthi Srilekha Sridhara Pattara Rattanawong Nithin Venepally Chieh-Ju Chao Hasan Ashraf Sai Harika Pujari Mohamed Allam Diana Almader-Douglas Yamini Alla Amit Kumar Farouk Mookadam Douglas L Packer David R Holmes Jr Donald J Hagler Floyd David Fortuin Reza Arsanjani | 2023 | World Journal of Cardiology2023，15，2： | 0 |
| 20 | Prediction of permanent pacemaker implantation after transcatheter aortic valve replacement:The role of machine learning显示文摘BACKGROUND Atrioventricular block requiring permanent pacemaker(PPM)implantation is an important complication of transcatheter aortic valve replacement(TAVR).Application of machine learning could potentially be used to predict preprocedural risk for PPM.AIM To apply machine learning to be used to predict pre-procedural risk for PPM.METHODS A retrospective study of 1200 patients who underwent TAVR(January 2014-December 2017)was performed.964 patients without prior PPM were included for a 30-d analysis and 657 patients without PPM requirement through 30 d were included for a 1-year analysis.After the exclusion of variables with near-zero variance or≥50%missing data,167 variables were included in the random forest gradient boosting algorithm(GBM)optimized using 5-fold cross-validations repeated 10 times.The receiver operator curve(ROC)for the GBM model and PPM risk score models were calculated to predict the risk of PPM at 30 d and 1 year.RESULTS Of 964 patients included in the 30-d analysis without prior PPM,19.6%required PPM post-TAVR.The mean age of patients was 80.9±8.7 years.42.1%were female.Of 657 patients included in the 1-year analysis,the mean age of the patients was 80.7±8.2.Of those,42.6%of patients were female and 26.7%required PPM at 1-year post-TAVR.The area under ROC to predict 30-d and 1-year risk of PPM for the GBM model(0.66 and 0.72)was superior to that of the PPM risk score(0.55 and 0.54)with a P value<0.001.CONCLUSION The GBM model has good discrimination and calibration in identifying patients at high risk of PPM post-TAVR. | Pradyumna Agasthi Hasan Ashraf Sai Harika Pujari Marlene Girardo Andrew Tseng Farouk Mookadam Nithin Venepally Matthew R Buras Bishoy Abraham Banveet K Khetarpal Mohamed Allam Siva K Mulpuru MD Mackram F Eleid Kevin L Greason Nirat Beohar John Sweeney David Fortuin David R Jr Holmes Reza Arsanjani | 2023 | World Journal of Cardiology2023，15，3： | 0 |
