On postimplant telemetry, 27 patients (50%) had NSVT, including 1 who had torsade de pointes, but most had &lt;5 episodes. Pre-TPVR NSVT or rhythm medications, diagnosis other than tetralogy, and substantial device contact with the myocardium were associated with more frequent NSVT on telemetry. Ten patients (19%) were started on a new antiarrhythmic medication. On discharge ERM, 37% of patients had NSVT, most with &lt;5 episodes and only 13% with NSVT beyond 5 days post-discharge. On follow-up ERM, 14% of patients had a single episode of NSVT and 1 had 5 episodes. During follow-up, antiarrhythmic medications were discontinued in 8 of 10 patients and no patients died or had sustained ventricular tachycardia.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>CONCLUSIONS:<\/jats:title>\n            <jats:p>NSVT and ventricular ectopy were common early after TPVR but were infrequent in most cases and diminished rapidly after discharge. The incidence of NSVT on follow-up ERM was similar to preimplant incidence. Few patients had antiarrhythmic medications initiated, and most were discontinued on follow-up. There were no major arrhythmic events after discharge.<\/jats:p>\n          <\/jats:sec>","DOI":"10.1161\/circinterventions.124.014381","type":"journal-article","created":{"date-parts":[[2024,12,27]],"date-time":"2024-12-27T10:00:17Z","timestamp":1735293617000},"update-policy":"https:\/\/doi.org\/10.1161\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":7,"title":["Extended Rhythm Monitoring to Assess for Ventricular Arrhythmias After Transcatheter Pulmonary Valve Replacement With the Harmony Valve"],"prefix":"10.1161","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4675-402X","authenticated-orcid":true,"given":"Jeffrey K.","family":"Yang","sequence":"first","affiliation":[{"name":"Department of Pediatrics, Pediatric Cardiology (J.K.Y., L.W., A.C.T., H.C., A.W.R., L.F.P., S.R.C., A.M.D., D.B.M.), Stanford University, Palo Alto, CA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4436-7106","authenticated-orcid":true,"given":"Laura","family":"Wattenbarger","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, Pediatric Cardiology (J.K.Y., L.W., A.C.T., H.C., A.W.R., L.F.P., S.R.C., A.M.D., D.B.M.), Stanford University, Palo Alto, CA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2133-4419","authenticated-orcid":true,"given":"Anne C.","family":"Taylor","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, Pediatric Cardiology (J.K.Y., L.W., A.C.T., H.C., A.W.R., L.F.P., S.R.C., A.M.D., D.B.M.), Stanford University, Palo Alto, CA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2859-3536","authenticated-orcid":true,"given":"Henry","family":"Chubb","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, Pediatric Cardiology (J.K.Y., L.W., A.C.T., H.C., A.W.R., L.F.P., S.R.C., A.M.D., D.B.M.), Stanford University, Palo Alto, CA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8547-8761","authenticated-orcid":true,"given":"Anitra W.","family":"Romfh","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, Pediatric Cardiology (J.K.Y., L.W., A.C.T., H.C., A.W.R., L.F.P., S.R.C., A.M.D., D.B.M.), Stanford University, Palo Alto, CA."},{"name":"Lucile Packard Children\u2019s Hospital, and Division of Cardiovascular Medicine, Department of Medicine, Stanford Health Care (A.W.R.), Stanford University, Palo Alto, CA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lynn F.","family":"Peng","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, Pediatric Cardiology (J.K.Y., L.W., A.C.T., H.C., A.W.R., L.F.P., S.R.C., A.M.D., D.B.M.), Stanford University, Palo Alto, CA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9473-0105","authenticated-orcid":true,"given":"Scott R.","family":"Ceresnak","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, Pediatric Cardiology (J.K.Y., L.W., A.C.T., H.C., A.W.R., L.F.P., S.R.C., A.M.D., D.B.M.), Stanford University, Palo Alto, CA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3786-1408","authenticated-orcid":true,"given":"Anne M.","family":"Dubin","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, Pediatric Cardiology (J.K.Y., L.W., A.C.T., H.C., A.W.R., L.F.P., S.R.C., A.M.D., D.B.M.), Stanford University, Palo Alto, CA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7242-0934","authenticated-orcid":true,"given":"Doff B.","family":"McElhinney","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, Pediatric Cardiology (J.K.Y., L.W., A.C.T., H.C., A.W.R., L.F.P., S.R.C., A.M.D., D.B.M.), Stanford University, Palo Alto, CA."},{"name":"Department of Cardiothoracic Surgery, Pediatric Cardiothoracic Surgery (D.B.M.), Stanford University, Palo Alto, CA."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","reference":[{"key":"e_1_3_3_2_2","doi-asserted-by":"publisher","DOI":"10.1161\/CIRCULATIONAHA.109.921692"},{"key":"e_1_3_3_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jacc.2009.06.034"},{"key":"e_1_3_3_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jacc.2020.10.041"},{"key":"e_1_3_3_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcin.2020.06.039"},{"key":"e_1_3_3_6_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcin.2024.07.036"},{"key":"e_1_3_3_7_2","doi-asserted-by":"publisher","DOI":"10.1161\/CIRCINTERVENTIONS.119.008320"},{"key":"e_1_3_3_8_2","unstructured":"Center for Devices and Radiological Health; Food and Drug Administration.
