“…As the duration of AF and stress in the LA increases, the degree of atrial remodeling enhances and this result in reduce in Hasan Ari et al, Electromechanical delay and atrial fibrillation atrial contraction velocities [17]. Several previous studies are consistent with our results [13,15]. However, measurements of LA systolic and late diastolic velocities in the early periods following cardioversion may show lower values than the real values because of atrial stunning.…”

“…External direct electrical cardioversion remains the most common and effective method for restoring normal sinus rhythm in patients with atrial fibrillation. There are few clinical and echocardiographic parameters of cardioversion success such as the duration of atrial fibrillation and the diameter of the left atrium (Henry et al 1976;Brodsyk et al 1989). The predictive value of these parameters is limited (Dittrich et al 1989).…”

Restoration of sinus rhythm by electrical cardioversion is a therapeutic option in appropriately selected patients with atrial fibrillation. It is important to determine predictors of electrical cardioversion outcome in patients with atrial fibrillation. Predictive value of clinical and conventional echocardiographic parameters for predicting cardioversion outcome is limited. The role of left atrial appendage (LAA) function, which may reflect left atrial contractile function, for prediction of cardioversion outcome remains unclear. We conducted a single center prospective study to evaluate the role of LAA function for prediction of cardioversion success in patients with atrial fibrillation. One hundred sixty three patients with atrial fibrillation underwent transthoracic and transesophageal echocardiography (TEE) before electrical cardioversion. LAA functions, including LAA peak flow velocity, LAA area and LAA ejection fraction, were examined. Cardioversion was successful in 133 patients and unsuccessful in 30 patients. Mean LAA peak emptying flow velocity was significantly higher in the patients with successful cardioversion than in those with unsuccessful cardioversion (0.34 ± 0.14 vs 0.27 ± 0.1 m/sec; p = 0.013). At multivariate logistic regression analysis, only LAA flow velocity (> 0.28 m/sec, odds ratio = 2.8 ; p = 0.03) proved to be an independent predictor of cardioversion success. LAA area ( p = 0.18) and LAA ejection fraction ( p = 0.52) were not different between successful and unsuccessful cardioversion groups. Therefore, measurement of LAA flow velocity provides valuable information for prediction of cardioversion outcome in patients with atrial fibrillation before TEE guided cardioversion.cardioversion; left atrial appendage (LAA) function; atrial fibrillation

“…The relationship among the size of the LA, success of the CV and the recurrence of the AF has been investigated in various studies using the antero-posterior left atrial dimension (AP-LAd) measurement method (3,4). In a limited number of studies where patients in which a sinus rhythm (SR) was established following a successful electrical or medical cardioversion were evaluated together, the link between the recurrence of the AF and LAVI has been shown to be stronger than the relationship between AF and AP-LAd.…”

The significance of the left atrial volume index in cardioversion success and its relationship with recurrence in patients with non-valvular atrial fibrillation subjected to electrical cardioversion: a study on diagnostic accuracy ABSTRACTObjective: The aim of this study was to assess the predictive value of the left atrial volume index (LAVI) in electrical cardioversion (ECV) and observe the recurrence rate of atrial fibrillation (AF) after a successful ECV in patients with non-valvular atrial fibrillation.Method: This study was designed as a diagnostic accuracy and prospective cohort study. Eighty patients (mean age 62±12 years; 52.5% female) were enrolled in study. LAVI was measured using the area-length method and the indexed body surface area. Patients in whom the sinus rhythm (SR) was established following the ECV were assessed according to the clinical and electrocardiography (ECG) findings at the first month and grouped as those with continued SR or recurrent AF. The Student's t, Mann-Whitney U, Fisher's exact, Chi-square tests, ROC and logistic regression analyses were used for statistical analysis.Results: Subsequent to the ECV, SR was achieved in 62.5% (n=50) Original Investigation Özgün Araşt›rma 18ÖZET Amaç: Çalışmamızın amacı, valvüler olmayan atriyal fibrilasyonlu (AF) hastalarda, sol atriyum volüm indeksi (SAVİ) ile elektif elektriksel kardiyoversiyon (EKV) başarısı ve başarılı EKV sonrası erken dönem AF tekrarı arasındaki ilişkiyi araştırmaktır. Yöntem: Bu araştırma tanısal ve ileriye dönük kohort bir çalışma olarak tasarlandı. Çalışmamıza toplam 80 hasta (ortalama yaş 62±12 yıl, %52.5 kadın) alındı. Sol atriyal volüm alan-uzunluk yöntemi ile belirlendi, vücut-yüzey alanına bölünerek SAVİ hesaplandı. Hastalar öncelikle EKV'nin sonucuna göre sinüs ritmi (SR)-AF olarak ve EKV sonrası SR sağlananlar kendi içerisinde 1. ay klinik ve elektrokardiyografi (EKG) bulgularına göre SR devam edenler ve AF gelişenler olarak ayrıldı. Student's t, Mann-Whitney U, Fisher's exact, Chi-square testleri, ROC ve lojistik regresyon analizleri istatistiksel değerlendirme için kullanıldı.
