The rates of readmissions after VT ablation are unknown. We sought to examine in-hospital outcomes, costs, and 30-day readmissions after catheter ablation of myocardial infarction\u2013associated VT.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>\n                      Using the Nationwide Readmissions Database, we evaluated 4109 admissions for catheter ablation of myocardial infarction\u2013associated VT occurring between 2010 and 2015.

Independent predictors of mortality included pulmonary hypertension, lung disease, obesity, and coagulopathy. Following discharge after VT ablation, the 30-day readmission rate was 19.2% with a median time to readmission of 10.0 days (IQR, 3.8\u201317.6 days) and an in-hospital mortality rate of 2.9%. Cardiac causes accounted for 74% of readmissions, with VT and congestive heart failure constituting 41% and 14% of all readmissions, respectively. Pulmonary hypertension, congestive heart failure, smoking, chronic pulmonary disease, and prolonged index hospitalization were significant independent predictors of 30-day readmission. After adjustment, 30-day readmissions were associated with a 38.9% increase in cumulative hospitalization costs.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions:<\/jats:title>\n                    <jats:p>Thirty-day readmissions after catheter ablation of VT occur in nearly 1 out of 5 cases, with the majority of readmissions being caused by recurrent VT or congestive heart failure. Baseline comorbidities are significant predictors of procedural mortality, complications, and readmissions. Strategies to reduce recurrent VT postablation by improving procedural success, optimizing postablation heart failure treatment, and ensuring close postdischarge follow-up may help reduce readmissions and healthcare costs.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1161\/circep.118.006754","type":"journal-article","created":{"date-parts":[[2018,10,31]],"date-time":"2018-10-31T05:00:25Z","timestamp":1540962025000},"update-policy":"https:\/\/doi.org\/10.1161\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":32,"title":["Outcomes, Costs, and 30-Day Readmissions After Catheter Ablation of Myocardial Infarct\u2013Associated Ventricular Tachycardia in the Real World"],"prefix":"10.1161","volume":"11","author":[{"given":"Jim W.","family":"Cheung","sequence":"first","affiliation":[{"name":"Weill Cornell Cardiovascular Outcomes Research Group (CORG), Division of Cardiology, Department of Medicine, Weill Cornell Medicine\u2013New York Presbyterian Hospital (J.W.C., J.E.I., G.T., C.F.L., S.M.M., B.B.L., L.K.K.)."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ilhwan","family":"Yeo","sequence":"additional","affiliation":[{"name":"Department of Medicine, Icahn School of Medicine at Mount Sinai, New York, NY (I.Y.)."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"James E.","family":"Ip","sequence":"additional","affiliation":[{"name":"Weill Cornell Cardiovascular Outcomes Research Group (CORG), Division of Cardiology, Department of Medicine, Weill Cornell Medicine\u2013New York Presbyterian Hospital (J.W.C., J.E.I., G.T., C.F.L., S.M.M., B.B.L., L.K.K.)."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"George","family":"Thomas","sequence":"additional","affiliation":[{"name":"Weill Cornell Cardiovascular Outcomes Research Group (CORG), Division of Cardiology, Department of Medicine, Weill Cornell Medicine\u2013New York Presbyterian Hospital (J.W.C., J.E.I., G.T., C.F.L., S.M.M., B.B.L., L.K.K.)."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christopher F.","family":"Liu","sequence":"additional","affiliation":[{"name":"Weill Cornell Cardiovascular Outcomes Research Group (CORG), Division of Cardiology, Department of Medicine, Weill Cornell Medicine\u2013New York Presbyterian Hospital (J.W.C., J.E.I., G.T., C.F.L., S.M.M., B.B.L., L.K.K.)."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Steven M.","family":"Markowitz","sequence":"additional","affiliation":[{"name":"Weill Cornell Cardiovascular Outcomes Research Group (CORG), Division of Cardiology, Department of Medicine, Weill Cornell Medicine\u2013New York Presbyterian Hospital (J.W.C., J.E.I., G.T., C.F.L., S.M.M., B.B.L., L.K.K.)."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bruce B.","family":"Lerman","sequence":"additional","affiliation":[{"name":"Weill Cornell Cardiovascular Outcomes Research Group (CORG), Division of Cardiology, Department of Medicine, Weill Cornell Medicine\u2013New York Presbyterian Hospital (J.W.C., J.E.I., G.T., C.F.L., S.M.M., B.B.L., L.K.K.)."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Luke K.","family":"Kim","sequence":"additional","affiliation":[{"name":"Weill Cornell Cardiovascular Outcomes Research Group (CORG), Division of Cardiology, Department of Medicine, Weill Cornell Medicine\u2013New York Presbyterian Hospital (J.W.C., J.E.I., G.T., C.F.L., S.M.M., B.B.L., L.K.K.)."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","reference":[{"key":"e_1_3_3_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.hrthm.2009.04.030"},{"key":"e_1_3_3_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.hrthm.2014.07.012"},{"key":"e_1_3_3_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jacc.2017.02.044"},{"key":"e_1_3_3_5_2","unstructured":"Healthcare Cost and Utilization Project (HCUP).
