Comparison of Pulmonary Outcome in Minimally Invasive (TCRAT) and Full Sternotomy CABG.

Background:  Pulmonary complications are among the main causes of increased mortality, and morbidity, as well as prolonged intensive care unit (ICU) and hospital stay after cardiac surgery. Recently, a sternum-sparing concept of minimally invasive total coronary revascularization via anterior minithoracotomy (TCRAT) was introduced. A higher risk of pulmonary injury could be anticipated due to the thoracic incision and the longer duration of surgery.

Right ventricular and pulmonary artery pulse pressure variation and systolic pressure variation for the prediction of fluid responsiveness: an interventional study in coronary artery bypass surgery patients.

Purpose: Predicting fluid responsiveness is essential when treating surgical or critically ill patients. When using a pulmonary artery catheter, pulse pressure variation and systolic pressure variation can be calculated from right ventricular and pulmonary artery pressure waveforms.

Methods: We conducted a prospective interventional study investigating the ability of right ventricular pulse pressure variation (PPV) and systolic pressure variation (SPV) as well as pulmonary artery pulse pressure variation (PPV) and systolic pressure variation (SPV) to predict fluid responsiveness in coronary artery bypass (CABG) surgery patients.
