1 Heart displacement during off-pump CABG: how well is it tolerated?
Arno P Nierich, MD, Jan Diephuis, MD, Erik W.L Jansen, MD, PhD, Cornelius Borst, MD, PhD, Johannes T.A Knape, MD, PhD  The Annals of Thoracic Surgery  Volume 70, Issue 2, Pages (August 2000) DOI: /S (00)

2 Fig 1 Incidence of employing Trendelenburg maneuver during anterolateral thoracotomy and sternotomy. (ALT = anterolateral thoracotomy; D = diagonal; LAD = left anterior descending artery; OM = obtuse marginal artery; RCA = right coronary artery; STERN = sternotomy.) ap < compared with STERN group. The Annals of Thoracic Surgery  , DOI: ( /S (00) )

3 Fig 2 Anesthesiologic measurements based on use of dopamine (3 to 5 μg · kg−1 · min−1) during anterolateral thoracotomy and sternotomy. (ALT = anterolateral thoracotomy; D = diagonal branch; LAD = left anterior descending artery; OM = obtuse marginal artery; RCA = right coronary artery; STERN = sternotomy.) ap < 0.05 compared with STERN group. The Annals of Thoracic Surgery  , DOI: ( /S (00) )

4 Fig 3 Acute hemodynamic alterations during tilting of the heart in order to reach the posterior wall. Note the decrease of ECG voltage, MAP, wedging of the pulmonary artery catheter, and the decrease of ET-CO2 but increase of CVP during the phase of placement of the stabilizer by the surgeon. After placement, these values normalized. (ABP = arterial blood pressure; CVP = central venous pressure; ET-CO2 = end tidal carbon dioxide; PAP = pulmonary artery pressure; RVP = right ventricular pressure.) The Annals of Thoracic Surgery  , DOI: ( /S (00) )

5 Fig 4 Four-chamber TEE view of the heart during placement of the stabilizer on posterior wall. (IAS = intraatrial septum; LA = left atrium; LV = left ventricle; RA = right atrium; RV= right ventricle.) The Annals of Thoracic Surgery  , DOI: ( /S (00) )
