Abstract Aims Monitoring of patients after ablation had wide variations in the ESC-EHRA atrial fibrillation ablation long-term (AFA-LT) registry. We aimed to compare four different monitoring strategies after catheter AF ablation. Methods and results The ESC-EHRA AFA-LT registry included 3593 patients who underwent ablation. Arrhythmia monitoring during follow-up was performed by 12-lead electrocardiogram (ECG), Holter ECG, trans-telephonic ECG monitoring (TTMON), or an implanted cardiac monitoring (ICM) system. Patients were selected to a given monitoring group according to the most extensive ECG tool used in each of them. Comparison of the probability of freedom from recurrences was performed by censored log-rank test and presented by Kaplan–Meier curves. The rhythm monitoring methods were used among 2658 patients: ECG (N = 578), Holter ECG (N = 1874), TTMON (N = 101), and ICM (N = 105). A total of 767 of 2658 patients (28.9%) had AF recurrences during follow-up. Censored log-rank test discovered a lower probability of freedom from relapses, which was detected with ICM compared to TTMON, ECG, and Holter ECG (P < 0.001). The rate of freedom from AF recurrences was 50.5% among patients using the ICM while it was 65.4%, 70.6%, and 72.8% using the TTMON, ECG, and Holter ECG, respectively. Conclusion Comparing all main electrocardiographic monitoring methods in a large patient sample, our results suggest that post-ablation recurrences of AF are significantly underreported by TTMON, ECG, and Holter ECG. The ICM estimates AF ablation recurrences most reliably and should be a preferred mode of monitoring for trials evaluating novel AF ablation techniques.

Abstract Background Radiofrequency catheter ablation (RFCA) for atrial fibrillation (AF) is becoming a routine procedure to treat patients with drug-refractory symptomatic AF. However, data regarding very long-term clinical outcomes is limited. The aim of the present study was to evaluate the 10-year clinical outcomes of patients who underwent RFCA for paroxysmal and persistent AF. Methods We retrospectively enrolled 503 consecutive patients (mean age 66,9±9,51 years; 71,6% male) who underwent RFCA for drug-refractory symptomatic AF between February 2004 and June 2011. Follow-up information was obtained using medical records and/or telephonic interviews with the patient, relatives and/or referring physicians. Results Among 503 patients enrolled in this study, 362 had paroxysmal atrial fibrillation (PAF) and 141 had persistent atrial fibrillation (PeAF) (72% and 28%, respectively). Mean follow-up was 8,84±3,05 years. The 10-year event-free rate for recurrent atrial tachyarrhythmia (AT) after the first procedure was 44,5% (49,4% for PAF vs 31,9% for PeAF; p=0,002 by log-rank test) and 81,9% after the last procedure (87,3% for PAF and 67,9% for PeAF; p≤0,001 by log-rank test). AT recurrence was observed most commonly during the first 12 months of the initial procedure (56%), with only 18% of them occurring after 60 months. Multivariate analysis revealed that persistent AF (hazard ratio=1,366; 95% confidence interval 1,058–1,76; p=0,017) and duration of AF &gt;5 years (hazard ratio=1,357; 95% confidence interval 1,064–1,732; p=0,005) were independent risk factors for AT recurrence. Regarding adverse events, there were 24 (4,8%) hospitalizations for acute decompensated heart failure, 20 (4%) ischemic strokes and 14 (2,8%) bleeding complications requiring hospital admissions. Patients taking oral anticoagulation and antiarrhythmic drugs at the end of the study accounted for 32,8% and 16,7% respectively. Conclusions RFCA for AF provided favorable results in terms of arrhythmia event-free survival in long-term follow-up with better results in patients with paroxysmal AF. Persistent AF and long-standing AF (beyond 5 years) were associated with AT recurrence. Despite the large number of patients who discontinued oral anticoagulation, thromboembolic adverse events were rare. FUNDunding Acknowledgement Type of funding sources: None.

ObjectiveTo investigate the association between the presence of ipsilateral nonstenotic carotid plaques and the rate of detection of atrial fibrillation (AF) during follow-up in patients with embolic strokes of undetermined source (ESUS).MethodsWe pooled data of all consecutive ESUS patients from 3 prospective stroke registries. Multivariate stepwise regression assessed the association between the presence of nonstenotic carotid plaques and AF detection. The 10-year cumulative probabilities of AF detection were estimated by the Kaplan-Meier product limit method.ResultsAmong 777 patients followed for 2,642 patient-years, 341 (38.6%) patients had an ipsilateral nonstenotic carotid plaque. AF was detected in 112 (14.4%) patients in the overall population during follow-up. The overall rate of AF detection was 8.5% in patients with nonstenotic carotid plaques (2.9% per 100 patient-years) and 19.0% in patients without (5.0% per 100 patient-years) (unadjusted hazard ratio [HR] 0.56, 95% confidence interval [CI] 0.37–0.84). The presence of ipsilateral nonstenotic carotid plaques was associated with lower probability for AF detection (adjusted HR 0.57, 95% CI 0.34–0.96, p = 0.03). The 10-year cumulative probability of AF detection was lower in patients with ipsilateral nonstenotic carotid plaques compared to those without (34.5%, 95% CI 21.8–47.2 vs 49.0%, 95% CI 40.4–57.6 respectively, log-rank-test: 11.8, p = 0.001).ConclusionsAF is less frequently detected in ESUS patients with nonstenotic carotid plaques compared to those without.Clinicaltrials.gov identifierNCT02766205.

Objective:Prolonged ECG monitoring after stroke frequently reveals short paroxysmal atrial fibrillation (pAF) and supraventricular (SV) runs. The minimal duration of atrial fibrillation (AF) required to induce cardioembolism, the relevance of SV runs, and whether short pAF results from cerebral damage itself are currently being debated. We aimed to study the relevance of SV runs and short pAF detected by prolonged Holter ECG after cerebral ischemia during long-term follow-up.Methods:Analysis is from the prospective Find-AF trial (ISRCTN46104198). We included patients with acute cerebral ischemia. Those without AF on admission received 7-day Holter ECG monitoring. We differentiated patients with AF on admission (AF-adm), with pAF (>30 seconds), with SV runs (>5 beats but <30 seconds in a 24-hour ECG interval), and without SV runs (controls). During follow-up, those with baseline pAF received another 7-day Holter ECG to examine AF persistence.Results:A total of 254 of 281 initially included patients were analyzed (mean age 70.0 years, 45.3% female). Forty-three (16.9%) had AF-adm. A total of 211 received 7-day Holter ECG monitoring: 27 (12.8%) had pAF, 67 (31.8%) had SV runs, and 117 (55.5%) were controls. During a mean 3.7 years of follow-up, the SV runs group had more recurrent strokes (p = 0.04) and showed numerically more novel AF (12% vs 5%, p = 0.09) than the controls. Seventy-five percent of the patients with manifest pAF detected after cerebral ischemia still had AF during follow-up (50% paroxysmal, 50% persisting/permanent).Conclusions:Patients with cerebral ischemia and SV runs had more recurrent strokes and numerically more novel AF during follow-up and could benefit from further prolonged ECG monitoring. pAF detected after stroke is not a temporal phenomenon.

11061 Background: TRB is FDA approved drug for the treatment of liposarcoma (Lipo) and leiomyosarcoma (LMS). The aim of this study was to evaluate potential biomarkers associated with prolonged benefit in patients treated with TRB at our center prior to 2016. Methods: We performed a retrospective search of UW/FHCRC CASIS database to identify patients treated with TRB prior to 2016. Demographic variables and clinical variables (such as histology and treatment) were retrieved. Statistics were performed with R 3.4.1 software. Pairwise Pearson’s correlation was calculated for the # of prior chemotherapy regimens with # of TRB cycles. The Kaplan-Meir method was used to evaluate overall survival (OS). Log-rank test was conducted to compare groups in terms of OS. Results: 145 sarcoma patients treated with TRB were identified with a mean follow up of 5 years (generally on NCT01427582 or NCT01343277). Patients averaged 1.9 prior chemotherapy regimens prior to TRB (range 0-7 regimens) and received an average of 5.6 TRB doses (range 1-25 doses). Subtypes are listed on table. The # of prior regimens was negatively correlated with the # of TRB cycles that patients received (pairwise correlation coefficient = -1.77; p=0.034), suggesting that multiple prior treatment lines either made TRB less tolerable or made sarcoma less sensitive to TRB. The median OS for this heavily treated metastatic population was 0.5 years. However, patients who were able to stay on TRB for more than 5 cycles had a significantly higher OS (p=0.001). While only 23% of patients who received less than 5 cycles of TRB were alive at 5 years (95% CI: 0.15, 0.32), 53% of those who received 5 or more cycles of (95% CI: 0.39, 0.65) were alive at 5 years. Conclusions: TRB may be more effective when administered as an earlier line of therapy. Patients who are able to stay on TRB for a longer duration had a significant improvement in OS. Detailed subset analysis will be presented as will initial findings of our biomarker work. These retrospective data warrant further evaluation. Clinical trial information: NCT01427582 or NCT01343277.

BACKGROUND/AIM To evaluate outcomes of concurrent Cox-Maze procedures in elderly patients undergoing high-risk cardiac surgery. MEHODS We retrospectively identified patients aged over 70 years with Atrial Fibrillation (AF) from 2011 to 2017 who had two or more other cardiac procedures. They were subdivided into two groups: 1. Cox-Maze IV AF ablation 2. No-Surgical AF treatment. Patients requiring redo procedures or those who had isolated PVI or LAAO were excluded. Heart rhythm assessed from Holter reports or 12-lead ECG. Follow-up data collected through telephone consultations and medical records. RESULTS There were 239 patients. Median follow up was 61 months. 70 patients had Cox-Maze IV procedures (29.3%). Demographic, intra- and post-operative outcomes were similar between groups although duration of pre-operative AF was shorter in Cox-Maze group (p=0.001). One (1.4%) patient in Cox maze group with 30-day mortality compared to 14 (8.2%) the control group (p=0.05). Sinus rhythm at annual and latest follow-up was 84.9% and 80.0% respectively in Maze group - significantly better than No-Surgical AF treatment groups (P<0.001). 160 patients (66.9%) were alive at long-term follow-up with better survival curves in Cox Maze group compared to No-Surgical treatment group (p=0.02). There was significantly higher proportion of patients in NYHA 1 status in Cox-Maze group (p=0.009). No differences observed in freedom from stroke (p=0.80) or permanent pacemaker (p=0.33). CONCLUSIONS. Surgical ablation is beneficial in elderly patients undergoing high-risk surgery - promoting excellent long-term freedom from AF and symptomatic/prognostic benefits. Therefore, surgical risk need not be reason to deny benefits of concomitant AF-ablation.
