Noninvasive visualization of the dilated main coronary arteries in coronary artery fistulas by cross-sectional echocardiography.

abstract：BACKGROUND:Current American and European guidelines emphasize the importance of rate-control treatments in treating atrial fibrillation with a Class I recommendation, although data on the survival benefits of rate control are lacking. The goal of the present study was to investigate whether patients receiving rate-cont...
