Procedure: cardiac surgery with opening of heart chambers. Will be including 167 patients to undergo cardiac surgery. After the main operation phase all heart cavities are sealed, left vent drainage is stopped, ascending aorta is punctured and cardiac massage is performed, ventilation is started and the heart is filled with volume. Operating table is positioned in the Trendelenburg position, and aorta is opened. The amount of air in the cavities is evaluated by transesophageal echocardiography.
