Background: Atrioventricular block (AVB) is common after transcatheter aortic valve replacement (TAVR) and permanent pacemaker (PPM) implantation is needed in up to 30% of patients. Main predictors of long term AVB are electrocardiographic. The purpose of this study is to assess the prognostic value of serial HV intervals measured before and after TAVR to shorten the timing of PPM implantation., Methods: His bundle recordings were performed before (HV1), immediately after TAVR (HV2) and at day 2 for Edwards Sapien (ES) and 5 for Medtronic CoreValve (CV) (HV3). PPM indications were high degree AVB before day 5 or prolonged HV interval ≥80ms at the last recording. High degree AVB after discharge was evaluated from the pacemaker memories and ECG at 1 and 6months., Results: Data were obtained in 84 patients (33% CV and 67% ES). HV values were not associated with early or late AVB. PPM were implanted in 27 patients (34%) for documented AVB (n=17, 24%), prolonged HV interval (n=9) or sick sinus syndrome (n=1). Persistent complete AVB during the procedure and postoperative high degree AVB were the only perioperative factors associated with further long term occurrence of high degree AVB (p=0.001 and p<0.001). On multivariate analysis, only postoperative high degree AVB was significant (p=0.001)., Conclusion: Pre- and post-operative HV measurements were not correlated with late AVB after TAVR. Perioperative persistent complete AVB and postoperative high degree AVB are the only factors to predict late AVB and should be considered for the decision of PPM implantation., (Copyright © 2017 Elsevier B.V.

Background: We aimed to assess whether the use of non-steroidal anti-inflammatory drugs (NSAIDs) is associated with an increased risk of cardiovascular (CV) events in stable patients with established atherothrombosis or multiple risk factors., Methods: We analysed the 23,728 European patients of the REACH Registry; 20,588 (86.8%) had established atherothrombotic disease and 3140 (13.2%) had multiple risk factors only. Aspirin (ASA) and/or NSAIDs use was determined at enrolment and ischemic events were recorded over two years of follow-up. cMACCE was defined as the composite of CV death, MI or stroke. Bleeding was defined as any bleeding leading to both hospitalisation and transfusion., Results: The mean age of population was 67.2±9.8years. At baseline, 1573 patients (6.6%) received NSAIDs and 15,395 (64.9%) received ASA. Four groups were defined: 1) no ASA/no NSAIDs, 2) ASA only, 3) NSAIDs only, 4) NSAIDs+ASA, with 7722 (32.5%), 14,433 (60.8%), 611 (2.6%) and 962 (4.1%) patients in these groups, respectively. Among the 22,028 (92.8%) with complete 2-year follow-up, 683 (3.2%) died from CV causes, while 395 (1.9%) had MI, 665 (3.1%) stroke, 1651 (7.6%) cMACCE and 199 (1.0%) bleeding. After adjustment, NSAID use was independently associated with an increased risk of stroke (OR 1.635; 95% CI 1.239-2.159, p<0.001), and a trend towards an increased bleeding rate (OR 1.554; CI 95% 0.960-2.51, p=0.07). No association was found between NSAID use and MI or MACCE., Conclusions: In stable atherothrombosis patients, the use of NSAIDs appears to be independently associated with an increased cerebrovascular event risk., (Copyright © 2011 Elsevier Ireland Ltd.
