Vibrating heart

This is a surgical video of a patient with an ascending aortic aneurysm and severe aortic insufficiency (Fig. 1). On palpation of the heart, there was a significant thrill. When we recorded a video of the heart when the pericardium was opened, there was no visible abnormality (Video 1). We thought of taking a video in slow motion. On diastole, the heart was fibrillating (Video 2)
