Background-The incidence, determinants, and outcome of postoperative atrial fibrillation (AF) after surgery for mitral regurgitation (MR) are poorly defined but may have important implications for timing of mitral valve surgery. Methods and Results-In 762 patients in sinus rhythm with no AF history undergoing MR surgical correction, we examined the rates and prognostic implications of postoperative AF for early AF (within 2 weeks postoperatively) and late AF (Ͼ2 weeks after surgery

“…However, the technique of visual estimation is validated 15 and has been adequate for good clinical risk stratification. 16 Because longitudinal follow-up was not undertaken for each patient, we were unable to determine postoperative rhythm over the course of time.…”

“…In human echocardiography, the estimation of global cardiac function obtained by echocardiography has been validated by other methods, such as LV angiography 10,20,21 or gated single photon emission computed tomography. 20,[22][23][24][25] Recently, there has been successful measurement of LV volume in mice using a miniaturized conductance catheter, 26,27 gated magnetic resonance imaging, 28,29 biplane LV angiography 30 and radionuclide ventriculography, 31 the last method being used in murine hearts with an occluded left anterior descending artery. Although each of these techniques provided excellent accuracy, they are still not widely available and are technically demanding.…”

eft coronary artery ligation is one of the most common methods of creating a model of myocardial infarction (MI) in the murine heart and M-mode echocardiography has been used to assess cardiac function because of its higher sampling frequency, which is particularly useful when assessing a heart rate (HR) of 600 beats/min or greater. 1-9 However, the estimation of global left ventricular (LV) function using M-mode echocardiography has limitations when it is applied to an infarcted heart 10 and 2-dimensional (2-D) echocardiography is more suitable. In murine hearts with their small size and high heart rate, however, even this method has been limited in its application for assessment of cardiac function because of the difficulty in obtaining adequate 2-D images.The recent improvements in 2-D echocardiography of a higher resolution and higher frame rate using a highfrequency transducer provide more accessible images for
