Air embolism prevention.

Abstract

Although fortunately rare, the serious and potentially fatal complication of air embolism continues to occur following open-heart surgery. Its reliable prevention is dependent on the avoidance of specific procedural hazards and the exercise of various maneuvers to evacuate residual air from the heart before it is allowed to eject. Specifically, the beating heart should not be opened without ventricular fibrillation, cardioplegia, or aortic cross-clamping unless special precautions are exercised.

3D heart model for computer simulations in cardiac surgery.

For a satisfactory computer simulation, a model, which imitates a natural situation, is needed. The Human heart is an irregular 3D object and thus difficult to reproduce. Basic data was taken from Visible Human Dataset (VHD), National Library of Medicine. The heart area was cut out of the original cross-sections and different tissues segmented. All the slices also had to be aligned to assure precise overlapping of the structures. A 3D computer heart model with the resolution of 1mm was designed. The heart model was dedicated to simulations of heat transfer during heart surgery however, it is applicable also to other medical simulations.
