We present the long-term results of cryoablation in 94 patients with paroxysmal and persistent AF treated in our center. Materials and Methods: This was an observational, retrospective study of 94 patients who underwent a cryoablation procedure for paroxysmal or persistent AF from 2015 to 2017. The follow up was 51 \u00b1 3 months. The absence of arrhythmia was checked at 6, 12, 24, and 48 months after the procedure with 24 h Holter monitoring. We evaluated echocardiography parameters before and 48 months after cryoablation. The quality of life was assessed by calculating EHRA scores at each visit. Results: The mean history of pre-procedural AF duration was 55.3 \u00b1 8.6 months. Paroxysmal AF was present in 42% of patients and persistent AF in 58%. Comparing the EHRA classes, a statistically significant difference was observed between the score assessed before the procedure and the score after one year, as well as when comparing the rates before the procedure and four years after the procedure (p &lt; 0.000). The recurrence of AF was observed in 22.3% of patients 1 year after the procedure, in 26.6% of patients 2 years after the procedure, and in 34% of patients 4 years after the procedure; 9.3% of them were left in permanent AF. During the observation period, 28% of patients underwent a repeated pulmonary vein isolation procedure, and 6% of patients had a permanent pacemaker implanted. Five hematomas (5%) and one instance of phrenic nerve palsy (1%) were observed during the procedure. Conclusions: The rate of arrhythmia recurrence increased every year after cryoablation. Quality of life improved after the procedure, despite the recurrence of AF. A quarter of patients had to undergo a repeat pulmonary vein isolation procedure.<\/jats:p>","DOI":"10.3390\/medicina59112036","type":"journal-article","created":{"date-parts":[[2023,11,20]],"date-time":"2023-11-20T00:30:50Z","timestamp":1700440250000},"page":"2036","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Results of a 4-Year Follow Up of Patients with Paroxysmal and Persistent Atrial Fibrillation after Cryoablation"],"prefix":"10.3390","volume":"59","author":[{"given":"Greta","family":"Radauskaite","sequence":"first","affiliation":[{"name":"Department of Cardiovascular Medicine, Vilnius University, 01513 Vilnius, Lithuania"},{"name":"Vilnius University Hospital Santaros Clinics, 08661 Vilnius, Lithuania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gediminas","family":"Ra\u010dkauskas","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Medicine, Vilnius University, 01513 Vilnius, Lithuania"},{"name":"Vilnius University Hospital Santaros Clinics, 08661 Vilnius, Lithuania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Svetlana","family":"Danilenko","sequence":"additional","affiliation":[{"name":"Department of Mathematical Statistics, Vilnius Gediminas Technical University, 10223 Vilnius, Lithuania"},{"name":"Department of Human and Medical Genetics, Vilnius University, 01513 Vilnius, Lithuania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Germanas","family":"Marinskis","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Medicine, Vilnius University, 01513 Vilnius, Lithuania"},{"name":"Vilnius University Hospital Santaros Clinics, 08661 Vilnius, Lithuania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Audrius","family":"Aidietis","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Medicine, Vilnius University, 01513 Vilnius, Lithuania"},{"name":"Vilnius University Hospital Santaros Clinics, 08661 Vilnius, Lithuania"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,11,19]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1689","DOI":"10.1016\/j.jacc.2020.02.025","article-title":"Atrial Fibrillation: JACC Council Perspectives","volume":"75","author":"Chung","year":"2020","journal-title":"J.
