“…We showed that the thoracoscope allows a larger visualization field and is useful for managing concomitant surgical procedures through the same single working port with better exposure and accuracy. 2 Particularly, the thoracoscope vision provides the operator with a direct line of sight into the left ventricle; 7 it allows assessment of the correct position of mitral and aortic prostheses (Supplemental Video 3). Moreover, in concomitant tricuspid valve surgery, the right atrium can be opened on the beating heart 2 to reduce clamping times.…”
