[Screening and diagnosis of atrial fibrillation].

Rev Prat 2020 Oct;70(8):899-902

Unité de rythmologie, centre cardio-vasculaire, CHU de Poitiers, Poitiers, France.

Screening and diagnosis of atrial fibrillation. Screening for atrial fibrillation (AF) is crucial as this arrhythmia is asymptomatic in a third of patients and 5% of patients present a stroke as the first manifestation of their AF. The European Society of Cardiology recommends opportunistic screening of AF in patients over 65 years of age and systematically in patients over 75 years of age. The simplest way is pulse taking, but the number of connected devices for AF screening allows to multiply the frequency of screening and thus increase sensitivity, with another advantage of a digitalized transmission of the tracing. However many questions remain. No scientific evidence has demonstrated a benefit for AF screening. We do not know what duration and frequency of screening is relevant. The burden of AF which increases thromboembolic risk is not known. What population should be screened and how to consider subclinical AF? We will obtain answers to our questions in the coming years thanks to the results of the various studies in progress.

Does Aortic Valve Calcium Score Still Predict Death, Cardiovascular Outcomes, and Conductive Disturbances after Transcatheter Aortic Valve Replacement with New-Generation Prostheses?

J Cardiovasc Echogr 2020 Apr-Jun;30(2):88-92. Epub 2020 Aug 17.

Department of Cardiology, Centre Régional Cardio-Vasculaire, CHU De Poitiers, Poitiers, France.

Background: The development of transcatheter aortic valve replacement (TAVR) has led to an improvement in morbidity-mortality in the treatment of severe aortic stenosis in patients at high surgical risk. However, the procedure is not free from life-threatening cardiovascular outcomes and conductive disturbances. The objective of our study was to analyze the prognostic impact of aortic valve calcium score on the occurrence of complications following the procedure.

Materials And Methods: Patients who have benefited from TAVR with the implantation of new-generation Sapien 3 and Evolut R aortic valve prostheses between January 2017 and July 2018 with the prior realization of a cardiac computed tomography with measurement of the aortic valve calcium score were retrospectively analyzed. Primary endpoint was a composite of death, stroke, and myocardial infarction within a period of 1 month after TAVR. Relation between valvular calcium and conductive disturbances was secondarily analyzed over the same period, and occurrences of high-degree atrioventricular block (paroxysmal or permanent), new-onset left bundle branch block, and the need for permanent or transient cardiac stimulation were associated with the secondary endpoint.

Results: Overall, 144 patients were included. The aortic valve calcium score was not significantly higher in patients who reached the primary endpoint (2936 ± 1235 vs. 3051 ± 1440, = 0.93). Among the 106 patients analyzed after excluding subjects with a prior pacemaker or left bundle branch block, aortic valvular calcium score was not statistically associated with the occurrence of conduction disturbances (3210 ± 1436 vs. 2948 ± 1223, = 0.31).

Conclusion: Our results suggest that the measurement of aortic valve calcium score has no prognostic value regarding mortality, cardiovascular events, or conductive disturbances after TAVR using the new generation of valves.

Hypnosis Versus Placebo During Atrial Flutter Ablation: The PAINLESS Study: A Randomized Controlled Trial.

JACC Clin Electrophysiol 2020 11 12;6(12):1551-1560. Epub 2020 Aug 12.

Centre Hospitalier Universitaire (CHU) Poitiers, Cardiology Department, Poitiers, France.

Objectives: The aim of this study was to assess the superiority of hypnosis versus placebo on pain perception and morphine consumption during typical atrial flutter (AFL) ablation.

Background: AFL ablation commonly requires intravenous opioid for analgesia, which can be associated with adverse outcomes. Hypnosis is an alternative technique with rising interest, but robust data in electrophysiological procedures are lacking.

Methods: This single center, randomized controlled trial compared hypnosis and placebo during AFl ablation. In addition to the randomized intervention, all patients were treated according to the institution's standard of care analgesia protocol (administration of 1 mg of intravenous morphine in case of self-reported pain ≥5 on an 11-point numeric rating scale or on demand). The primary endpoint was perceived pain quantified by patients using a visual analog scale.

Results: Between October 2017 and September 2019, 113 patients (mean age 70 ± 12 years, 21% women) were randomized to hypnosis (n = 56) or placebo (n = 57). Mean pain score was 4.0 ± 2.2 in the hypnosis group versus 5.5 ± 1.8 in the placebo group (p < 0.001). Pain perception, assessed every 5 min during the whole procedure, was consistently lower in the hypnosis group. Patients' sedation scores were also better in the hypnosis group than in the placebo group (8.3 ± 2.2 vs. 5.4 ± 2.5; p < 0.001). Finally, morphine requirements were significantly lower in the hypnosis group (1.3 ± 1.3 mg) compared with the placebo group (3.6 ± 1.8 mg; p < 0.001).

Conclusions: In this first randomized trial, hypnosis during AFL ablation was superior to placebo for alleviating pain and reducing morphine consumption.

Prognostic value of Charlson Comorbidity Index in the elderly with a cardioverter defibrillator implantation.

Int J Cardiol 2020 09 26;314:64-69. Epub 2020 Mar 26.

CHU Poitiers, Service de Cardiologie, 2 rue de la Milétrie, F-86021 Poitiers, France; Univ Poitiers, Faculté de Médecine et Pharmacie, F-86021 Poitiers, France; INSERM CIC 1402, CHU Poitiers, 2 rue de la Milétrie, F-86021 Poitiers, France. Electronic address:

Background: Elderly patients are often underrepresented in implantable cardioverter defibrillator (ICD) trials, and ICD implantation in patients ≥75 years consequently remains controversial. We aimed to evaluate mortality, appropriate ICD therapy rates and survival gain in an elderly population after risk stratification according to the Charlson Comorbidity Index (CCI).

Methods: This monocentric retrospective study included elderly ICD patients ≥75 years. They were subdivided according to their CCI score into 3 categories (0-1, 2-3 or ≥4 points). Elderly patients were matched 1:2 with younger control ICD patients on gender, type of prevention (primary or secondary) and type of device (associated cardiac resynchronization therapy or not).

Results: Between January 2009 and July 2017, 121 elderly patients (mean age 78 ± 3; 83% male) matched with 242 controls (mean age 66 ± 5) were included. At 5 year follow-up after ICD implantation, overall survival was 78%, 57%, and 29% (P = 0.002) in the elderly with a CCI score of 0-1, 2-3 and ≥4 respectively, and 72% in controls. There was no significant difference regarding ICD appropriate therapy between the 3 subgroups despite a trend towards lower rates of therapy in CCI ≥ 4 points patients (34.2%, 39.7% and 22.8% respectively; P = 0.45). Median potential survival gain after an appropriate therapy was >5, 4.7 and 1.4 years, with a CCI score of 0-1, 2-3 and ≥4 respectively (P = 0.01).

Conclusion: Elderly patients with CCI score ≥ 4 had the lowest survival after ICD implantation and little survival gain in case of appropriate defibrillator therapy. More than age alone, the burden of comorbidities assessed by the CCI could be helpful to better select elderly patients for ICD implantation.
