Prediction of Atrial Fibrillation Being Asymptomatic at First Onset by Cardiac Pacing
This study was focused on the symptoms of AF, especially palpitation, in pacemaker patients. We assessed the hypothesis that absence of palpitation during rapid ventricular pacing could be a predictor of future onset AF being asymptomatic.In this study, we assessed the presence of symptoms during RV pacing and AF symptoms on 145 pacemaker patients at the outpatient clinic by VVI pacing at 120 ppm. The relationship between symptoms during RV pacing and symptom during AF was assessed. The predictive value of absence of symptom during RV pacing on AF being asymptomatic was assessed.Of 145 patients, 74 had previous AF episode....

Giant Thrombus Formation Immediately After Mitral Valvuloplasty.
We report the case of a 65-year-old woman with severe mitral regurgitation (MR) and AF in whom a giant thrombus formed almost immediately after mitral and tricuspid valvuloplasty and concurrent LAA resection. No atrial thrombus or spontaneous echo contrast (SEC) was detected by TEE before the surgery. However, a giant intramural thrombus was detected in the left atrium 7 days after surgery. It was thought that the atrial dysfunction as well as the change in morphology of the left atrium resulting from the severe MR complicated by AF and congestive heart failure produced a thrombotic substrate. This case suggests that caref...

Left Atrial Remodeling Assessed by Transthoracic Echocardiography Predicts Left Atrial Appendage Flow Velocity in Patients With Paroxysmal Atrial Fibrillation.
Authors: Watanabe A, Suzuki S, Kano H, Matsuno S, Takai H, Kato Y, Otsuka T, Uejima T, Oikawa Y, Nagashima K, Kirigaya H, Kunihara T, Sagara K, Yamashita N, Sawada H, Aizawa T, Yajima J, Yamashita T Abstract Atrial fibrillation (AF) is associated with an increased risk of stroke and other thromboembolic events. Left atrial (LA) thrombus formation is closely related to LA dysfunction, particularly to decreased LA appendage flow velocity (LAA-FV) in patients with AF. We estimated LAA-FV using parameters noninvasively obtained by transthoracic echocardiography (TTE) in patients with paroxysmal AF.Echocardiographic and...

Usefulness of a Combination of Interatrial Block and a High CHADS2 Score to Predict New Onset Atrial Fibrillation.
In conclusion, IAB and a high CHADS2 score independently and synergistically predict new onset AF in patients in sinus rhythm, indicating an approximately 12-fold higher risk in patients with both IAB and a high CHADS2 score. Patients meeting these criteria should have more aggressive early intervention to prevent AF. PMID: 27593538 [PubMed - as supplied by publisher]
