Abstract
Coronary artery bypass grafting (CABG) has reached a prominent status in the treatment of coronary artery disease. The main objective of CABG is increasing coronary blood flow to ischemic myocardium in order to preserve and improve ventricular function. Objective measurements of the completeness of myocardial revascularization during and immediately after CABG have been limited by an inability to assess regional myocardial perfusion. The combination of intraoperative two-dimensional (2-D) echocardiography with the use of intravascular echocardiographic contrast agents (contrast echocardiography makes ultrasonic imaging an attractive method to assess regional myocardial perfusion during surgical revascularization. In addition, this method has shown promise in studying transmural changes in myocardial blood flow and in the quantitation of myocardial perfusion. The intraoperative application of this procedure to coronary artery surgery could allow immediate assessment of the completeness of surgical myocardial revascularization.
