Is echocardiography valid and reproducible in patients with atrial fibrillation? A systematic review

AbstractAimsEchocardiography is vital in the routine assessment and management of atrial fibrillation (AF). We performed a systematic review of the validity and reproducibility of echocardiographic left ventricular systolic and diastolic function in AF, and optimal acquisition methods.Methods and resultsOnline databases were searched for studies in patients with AF at the time of echocardiography (1960 to August 2015), prospectively registered with PROSPERO (CRD42015025297). The systematic review included 32 studies from 3  066 search results (1 968 patients with AF). Average age was 67 years, 33% were women, mean LVEF 53% (±10%), and average E/e’ 11.7 (±2.7). Data on the validity and reproducibility of systolic indices were extremely limited. In contrast, diastolic parameters demonstrated correlation with invas ive filling pressure and adequate reproducibility: E/e’ (n = 444)r =  0.47 to 0.79; IVRT (n = 177)r =  –0.70 to –0.95; E/Vp` (n = 55)r =  0.63 and 0.65; pulmonary vein diastolic flow (n = 67)r =  –0.80 and –0.91. Elevated E/e’ (>15) was associated with functional capacity, quality of life, and impaired prognosis. For optimal acquisition in AF patients, cardiac cycles with controlled heart rate (

ConclusionsThis study is the largest European real-world study ever published on NOACs. It includes all Italian patients treated with NOACs since 2013 accounting for about 1/3 of subjects with AF. The enrolled population consisted of very elderly patients, at high risk of ischemic adverse events. The AIFA registries are consolidated tools that guarantee the appropriateness of prescription and provide important information for the governance of National Health System by collecting real-world data.

AbstractThe prognostic impact of left atrial size in patients without systolic dysfunction nor atrial fibrillation (AF) has not been fully elucidated in Japan. We retrospectively analyzed data obtained from 4444 consecutive patients who had undergone both scheduled transthoracic echocardiography and electrocardiography in 2013 in our hospital. Those who presented with a history of myocardial infarctions, severe and moderate valvular diseases, low ejection fraction (  34 ml/m2. The primary outcome measure was a composite of all-cause death and major adverse cardiac events. A total of 2792 patients were categoriz...

This study aimed to prospectively evaluate the acute results of pulmonary vein isolation (PVI) using a novel CBA technique —the earliest potential (EP) of PV-guided CBA—in paroxysmal AF. We pressed a balloon against the earliest PV potential site during PVI when TTI could not be achieved within 60 s (EP-guided CBA group). We compared 32 patients consecutively treated by EP-guided CBA to 32 patients treated without pressing the balloon against the EP site (conventional CBA group). The cryoapplication protocol was the same, except with regard to the pressing of the balloon. All 256 PVs (EP-guided CBA group, ...

Authors: Lancellotti P, De Pauw M, Claeys M Abstract Cardiovascular disease (CVD) and cancer represent the two main causes of death in industrialised countries. Both share common risk factors (diabetes, obesity, hypertension, diet, smoking, etc.). The associated timing of CVD and cancer onset is thus largely influenced by modifiable risk factors. Advances in cancer treatment have extended the lives of patients with cancer, but for some at the cost of adverse cardiovascular events. The rapidly growing number of patients surviving cancer, often in the setting of advanced age, new or pre-existing CV disease and risk f...

Background: It is important to understand the risk of thromboembolism and bleeding in patients with nonvalvular atrial fibrillation (NVAF) receiving direct oral anticoagulants; however, data on risk factors in Japanese patients are limited. Methods: XAPASS (Xarelto Post-Authorization Safety and Effectiveness Study in Japanese Patients with Atrial Fibrillation) is a prospective observational study examining the safety and effectiveness of rivaroxaban in Japanese real-world clinical practice. We investigated risk factors for stroke/noncentral nervous system systemic embolism (non-CNS SE)/myocardial infarction (MI) and major ...
