Abstract/OtherAbstract:
Cardiac maneuvering during off-pump coronary artery bypass surgery can compress the right ventricle, causing temporary dysfunction and hemodynamic instability. The hemodynamic impact of a decompression technique comprising right pleurotomy and pericardial release was investigated during cardiac elevation. Intraoperative continuous real-time monitoring of cardiac index and stroke volume index was carried out using the PulseCO system in 12 consecutive patients with normal ventricular function who underwent off-pump coronary artery bypass by a single surgeon. A pulmonary artery catheter was used to monitor pulmonary artery pressure and systemic venous O(2) saturation. Hemodynamic changes during vertical displacement of the heart were measured before and after performing a right pleurotomy and pericardial release. Following right heart decompression, stroke volume index, cardiac index, mean arterial pressure, and systemic venous O(2) saturation were significantly better preserved during cardiac elevation. This demonstrates that right heart decompression via pleurotomy and pericardial release significantly improves hemodynamic stability during cardiac manipulation. We recommend the use of this procedure in off-pump coronary artery bypass when cardiac tilting is required.
