The median follow-up periods of 117 patients after the first and last ablation were, respectively, 82 (IQR 15) and 72 (IQR 30) months. PVIOD 1 included 32.5% of patients, those with successful single pulmonary vein isolation (PVI); PVIOD 2 included 29.1% of subjects, those with success after multiple procedures; PVIOD 3 comprised 14.5% of patients, those with clinical success; and PVIOD 4 included 23.9% of cases, those with procedural and clinical failure. In the multivariate ordinal logistic regression analysis, PVIOD 1–4 were independently associated with longstanding persistent AF with paroxysmal AF as the referent category (odds ratio (OR), 3.5; 95% confidence interval (95% CI), 1.1–10.7 (p = 0.031)), left atrial (LA) diameter (OR, 1.2; 95% CI, 1.1–1.3 (p = 0.001)) and left ventricular ejection fraction (LVEF) (OR, 0.9; 95% CI, 0.86–1.0 (p = 0.038)). LA size > 41 mm, LVEF ≤ 50% and longstanding persistent AF are strong predictors of AF recurrence. PVIOD 1–4 offer the most exact long-term prognosis of PVI. The purpose of the present article is to expand the quantitative measure of procedural success in the medical and biological fields. http://creativecommons.org/licenses/by/4.0/legalcode Jurčević, Ružica Angelkov, Lazar Tasić, Nebojša Tomović, Milosav Kojić, Dejan Otašević, Petar Bojić, Milovan Journal of clinical medicine 10(24) Pulmonary vein isolation outcome degree is a new score for efficacy of atrial fibrillation catheter ablation
