Abstract WP201: Stroke Patients With Atrial Fibrillation Detected by 72 hour- versus Prolonged ECG-monitoring

2018

Background: Detecting concealed paroxysmal atrial fibrillation (pAF) is a major focus in the workup of ischemic-stroke-patients. The minimal ECG-monitoring for stroke patients was recently expanded from 24 to 72 hours. However, it has been shown that even more prolonged monitoring reveals further pAF-cases. Our aim was to determine, whether known predictors for underlying pAF differ between stroke patients with AF that occurs on shorter (72h) or more prolonged ECG-monitoring (>72h). Methods: The Find-AF RANDOMISED -trial (NCT01855035) evaluated 3x10-day Holter-ECG vs. standard-care in patients > 60 years with acute ischemic strokes with the primary endpoint of novel pAF after 6 month…

Abstract 124: How to Preselect Stroke Patients for Enhanced ECG-Monitoring - Evaluation of Predictors of Paroxysmal Atrial Fibrillation in "Find-AFra…

2019

Background: Detecting concealed paroxysmal atrial fibrillation (pAF) is a major focus of the workup of ischemic-stroke-patients, but requires elaborate ECG-monitoring. We aimed to evaluate pre-specified predictors to determine stroke patients with an increased probability of underlying pAF. We applied cut-off-levels recently suggested by the German Stroke Society 1 . Methods: The Find-AF RANDOMISED -trial (NCT01855035) evaluated 3x10-day Holter-ECG vs. standard-care in 398 patients > 60 years with acute ischemic strokes. The primary endpoint was novel pAF after 6 months. 27 patients in the intervention arm (13.5 %) and 9 patients in the control arm (9.0 %) met the primary endpoint (p=0.…

Abstract WP200: Development and Validation of a Score to Detect Paroxysmal Atrial Fibrillation During Long-term Holter-monitoring After Acute Ischemi…

2018

Introduction: Atrial fibrillation remains one of the most common causes of ischemic stroke. The diagnosis of paroxysmal atrial fibrillation (pAF) frequently escapes routine diagnostic due to its intermittent and asymptomatic occurrence. Currently prolonged monitoring times (72h) are recommended, but did not find their way into everyday practice. Therefore an individual patient selection for prolonged ECG-monitoring might increase the diagnostic yield of pAF in a resource-saving and cost-effective manner. Methods: We used individual patient data from three prospective studies (n total =1556) which performed a prolonged Holter ECG-monitoring (at least 72 h) and centralized data evaluation af…

N-Terminal amino acid sequence analysis indicates that isolated atrial amyloid is derived from atrial natriuretic peptide

1988

Isolated atrial amyloid, the most frequent senile cardiac amyloid type, was chemically analysed. Amyloid fibrils obtained from a patient (NIP) were extracted and the predominant low-molecular-weight polypeptide (approximately 3.5 kDa, designated ASc2 NIP) was isolated by size exclusion high performance liquid chromatography in 60% formic acid. N-Terminal amino acid sequence analysis of this polypeptide was identical to that of the atrial natriuretic peptide alpha-hANP for the first 12 residues determined.

Adherence to antithrombotic therapy guidelines improves mortality among elderly patients with atrial fibrillation: insights from the REPOSI study

2016

Background: Atrial fibrillation (AF) is associated with a substantial risk of thromboembolism and mortality, significantly reduced by oral anticoagulation. Adherence to guidelines may lower the risks for both all cause and cardiovascular (CV) deaths. Methods: Our objective was to evaluate if antithrombotic prophylaxis according to the 2012 European Society of Cardiology (ESC) guidelines is associated to a lower rate of adverse outcomes. Data were obtained from REPOSI; a prospective observational study enrolling inpatients aged ≥65 years. Patients enrolled in 2012 and 2014 discharged with an AF diagnosis were analysed. Results: Among 2535 patients, 558 (22.0 %) were discharged with a diagnos…

Chronic atrial fibrillation in presence of aortic stenosis in a patient with polysplenia syndrome.

2013

We report a rare case of “situs viscerum ambiguous” with polysplenia syndrome, in a 69 year old female patient with aortic stenosis and chronic atrial fibrillation. The presenting symptom was dyspnoea on moderate exertion and an ECG showed supra ventricular arrhythmia. Patients trans-thoracic echocardiogram revealed a dilated left atrium, reduced ejection fraction, mild tricuspid regurgitation, moderate-severe pulmonary hypertension and severe aortic stenosis. The patient was successfully treated with a replacement of her aortic valve and ascending aorta.

Three-Dimensional Echocardiographic Evaluation of Aortic and Mitral Valve Stenosis

2001

Dynamic volume rendered three-dimensional echocardiography allows the spatial recognition of anatomy and function of the aortic and mitral valves with acceptable image quality. The aortic valve can be best visualized in a view from the ascending aorta down to the valve level, thus allowing an overview of the aortic aspect of the valve in a surgeon's perspective in ∼ 80% of patients. Planimetric measurement of the aortic valve area was possible in 88% of patients, and there is no systematic overestimation or underestimation of aortic valve area compared with two-dimensional echocardiography and catheterization. The entire valvular circumference of the mitral valve can be assessed from both a…

Isomeric arrangement of the left atrial appendages and visceral heterotaxy: two atypical cases.

2000

AbstractWe present two cases in which there was isomeric arrangement oi the left atrial appendages in association with multiple spleens and complete heart block. In both of these, the venous connections were normal. In one case the arrangement of the bronchial tree and the lungs was normal, the liver was left-sided, and the stomach was right-sided. In the other case, there was left isomeric broncho-pulmonary morphology, and both liver and stomach were right-sided. These unusual combinations show the need for full description of the morphology of other organs, and the venoatrial connections, in cases with isomeric arrangement of the atrial appendages. They also demonstrate that connection of…

Initial and long-term antithrombotic therapy after left atrial appendage closure with the WATCHMAN

2020

Abstract Background Evidence regarding post-procedural antithrombotic regimes other than used in randomized trials assessing percutaneous left atrial appendage (LAA) closure is limited. Purpose The present work aimed to compare different antithrombotic strategies applied in the real-world EWOLUTION study. Methods A total of 998 patients with successful WATCHMAN implantation at 47 centers were available for the present analysis. The composite ischemic endpoint of stroke, TIA, systemic embolism and device thrombus as well as the bleeding endpoint defined as at least major bleeding according to BARC were assessed during an initial period (from implant until first medication change) and long-te…
