Selami Dogan, MD, Kai Graubitz, MD, Tayfun Aybek, MD, Mohammad Fawad Khan, MD, Paul Kessler, MD, PhD, Anton Moritz, MD, PhD, Gerhard Wimmer-Greinecker, MD, PhD  The Annals of Thoracic Surgery  Volume 74, Issue 5, Pages (November 2002) DOI: /S (02)

2 Fig 1 Creatine kinase concentration graph. Sampling time: 1 = before induction of anesthesia; 2 = after induction of anesthesia; 3 = after onset of cardiopulmonary bypass; 4 = immediately before release of the aortic cross-clamp. Squares = minimally invasive group; X = conventional group. p < The Annals of Thoracic Surgery  , DOI: ( /S (02) )

3 Fig 2 Myoglobin graph. Sampling times: 1 = before induction of anesthesia; 2 = after induction of anesthesia; 3 = after onset of cardiopulmonary bypass; 4 = immediately before release of the aortic cross-clamp; 5 = 5 minutes after release of the aortic cross-clamp; 6 = 1 hour after surgery; 7 = 24 hours after surgery; 8 = 5 days after surgery. Squares = minimally invasive group; X = conventional group. p < The Annals of Thoracic Surgery  , DOI: ( /S (02) )

4 Fig 3 Protein S-100B graph. Sampling times: 1 = before induction of anesthesia; 2 = after induction of anesthesia; 3 = after onset of cardiopulmonary bypass; 4 = immediately before release of the aortic cross-clamp; 5 = 5 minutes after release of the aortic cross-clamp; 6 = 1 hour after surgery; 7 = 24 hours after surgery; 8 = 5 days after surgery. Squares = minimally invasive group; X = conventional group. p < The Annals of Thoracic Surgery  , DOI: ( /S (02) )

5 Fig 4 Neuron specific enolase graph. Sampling times: 1 = before induction of anesthesia; 2 = after induction of anesthesia; 3 = after onset of cardiopulmonary bypass; 4 = immediately before release of the aortic cross-clamp; 5 = 5 minutes after release of the aortic cross-clamp; 6 = 1 hour after surgery; 7 = 24 hours after surgery. Squares = minimally invasive group; X = conventional group. p = NS. The Annals of Thoracic Surgery  , DOI: ( /S (02) )
