Nowadays, new technology for imaging, information storage, and its transmission is almost everywhere. In the medical field, multi-slice computed tomography (CT), allowing for simultaneous acquisition of many images in parallel, and quick three-dimensional reconstruction is just one example that has the potential to make significant changes in the daily practice, not only for thoracic and cardio-vascular surgeons, but others too. The fact, that the lumen of the main coronary arteries can be demonstrated quite well with multi-slice CT makes clear, that for a number of questions, it is no longer necessary to realize a coronary angiography. There can be little doubt, that the advent of new players in the coronary artery scene will also impact its future development. In addition, the age of multi-slice CT is just beginning and numerous other applications can be expected like, e.g. systematic preoperative identification of the origin of Adamcievic's artery in thoraco-abdominal aortic aneurysms, postoperative functional assessment of a totally implantable left ventricular assist device [1], etc.
For traditional access to information, it is sufficient to indicate its source (ref. [1]) in order to be able to retrieve the corresponding document. However, the function of a totally implanted pulsatile pump, that by definition includes moving parts, is best assessed by a streaming video (see video 1 in ref. [1]). Following the experience of Interactive Thoracic and Cardio-vascular Surgery [2,3] the European Journal of Cardio-thoracic Surgery [1] now offers and accepts short video clips for illustration of the manuscripts submitted (see Instructions to Authors, pp. 674–675 of this issue; http:www.elsevier.com/locate/ejcts). It is essential for the time being to keep these video clips short in order to achieve reasonable delays for downloading. However, the increasing availability of broad-band transmission will certainly allow for larger files shortly.
Better availability of information brings up a new type of problem, which is its transformation into knowledge. We all know very well the daily practice in the operating theatre, where it is of prime importance for the life of the patient, to keep in sight his vital parameters (www.lifesight.org). As a matter of fact the information from the operating field (Fig. 1a) has to be frequently up-dated by the continuously collected information about haemodynamics, etc. (Fig. 1b). For the time being, it is for the surgeon necessary in most operating theatres, to slightly change the position of his head, to focus onto a remote screen, where he has to catch the displayed curves and numbers before he can return to the operating field, the place, where the focus of his activity is supposed to be. This sequential process happens several times a minute and increases in frequency during haemodynamically critical situations – exactly then, when full attention to the surgical field is required most. Although it has been standard for quite some time in endoscopic surgery to present on the same screen exposure parameters and video-endoscopically achieved operative views (Fig. 2) , more integration of information is now not only feasible, but mandatory.

There can be no doubt that real time lifesight in conjunction with on-line access to key diagnostic data including still images and video on command, is of prime importance for rapid decision making, or better, decision making within a useful time frame, all key requirements for successful thoracic and cardio-vascular surgery.
