This study reviews contemporaneous outcomes and predictors for late reinterventions after ASO.<h4>Methods</h4>We retrospectively reviewed patients who underwent ASO for dextro-transposition of the great arteries from 1997 to 2017. Technical performance score (TPS) class (class 1, trivial or no residua; class 2, minor residua; class 3, major residua or reintervention) was assigned at discharge based on echocardiographic evaluation of components of the ASO. Multivariable Cox regression identified patient- and procedure-specific factors associated with postdischarge reinterventions.<h4>Results</h4>Among 598 patients, 410 (69%) underwent ASO and 188 (31%) underwent ASO with ventricular septal defect repair. Median age at surgery was 5 days (interquartile range, 3 to 7); median follow-up time was 8.2 years; 408 (68%) were male; 50 (8.3%) were premature; and 10 (1.7%) had noncardiac anomalies or syndromes. Survival to hospital discharge was 98% (n = 591). Among 349 patients with follow-up, freedom from unplanned reintervent2ion at 5 years was 99% for TPS class 1, compared with 84% for class 2 and 30% for class 3. On multivariable Cox regression, classes 2 and 3 had significantly higher hazard for reintervention (class 2 hazard ratio 10.6; 95% confidence interval, 2.5 to 44.2; P = .001; class 3 hazard ratio 58.2, 95% confidence interval, 13.1 to 259; P < .001).<h4>Conclusions</h4>At our center, ASO was associated with relatively low mortality. Class 2 and class 3 TPS were the most important independent predictors of reinterventions after discharge. Therefore, TPS can serve as a tool for identifying high-risk patients who warrant closer follow-up.","is_dataset_classified":null,"base_score":2.5649493574615367,"endowment":2.5649493574615367,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"32603709","pmcid":null,"openalex_id":"https://openalex.org/W3037194828","authors":[],"funders":[],"total_grants":0,"fwci":1.2323,"citation_percentile":0.7959528,"influential_citations":0,"citation_trend":[{"year":2022,"count":7},{"year":2023,"count":2},{"year":2024,"count":2},{"year":2025,"count":1}],"oa_status":"closed","license":"https://www.elsevier.com/legal/tdmrep-license","oa_locations":[{"url":"https://api.elsevier.com/content/article/PII:S0003497520310213?httpAccept=text/xml","host_type":"publisher"},{"url":"https://api.elsevier.com/content/article/PII:S0003497520310213?httpAccept=text/plain","host_type":"publisher"},{"url":"https://doi.org/10.1016/j.athoracsur.2020.05.057","host_type":"journal"},{"url":"https://pubmed.ncbi.nlm.nih.gov/32603709","host_type":"repository"}],"fields_of_study":["Congenital Heart Disease Studies","Renal and Vascular Pathologies","Tracheal and airway disorders"],"mesh_terms":["Arterial Switch Operation","Child","Child, Preschool","Echocardiography","Female","Follow-Up Studies","Humans","Infant","Infant, Newborn","Male","Patient Discharge","Retrospective Studies","Transposition of Great Vessels"],"keywords":["Medicine","Interquartile range","Hazard ratio","Confidence interval","Great arteries","Proportional hazards model","Cardiology","Surgery","Internal medicine","Heart disease"],"sdg_mappings":[{"sdg_number":0,"sdg_label":"Good health and well-being"}],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-08-02T23:16:47.850859Z","pmid":null,"pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
