Breathing rates and heart rate spectrograms regarding body position in normal subjects.

The right lateral body position has been proposed as an effective vagal enhancer. However, the possibility of breathing affecting heart rate power spectra in different body positions has not been assessed. The level of vagal modulation in various body positions in normal subjects was estimated by calculating heart rate power spectra. The results suggest that the levels of vagal modulation do not necessarily reflect a change due to assuming different body position, but might be the consequence of changed breathing patterns. Before adopting the right lateral body position as vagal enhancing, the contribution of varying breathing pattern should be eliminated.

Endoscopic aortic valve replacement.

During the last 8 years, many different approaches for minimally invasive aortic valve surgery have emerged. We have developed a technique that enables total endoscopic aortic valve replacement with port access, via a small right lateral thoracotomy with only soft tissue retraction and minimally invasive aortic crossclamping. The operation is performed under video guidance, since no direct eye vision is possible. We believe this is the first such operation performed in cardiac surgery and that it mak es possible broadening of indications for nonsternotomy-video-directed surgery in the future.
