Intensive imaging assessment for successful minimally invasive cardiac surgery.
To clarify special imaging assessment that is useful for minimally invasive cardiac surgery (MICS), we examined 141 cases of MICS operations with ministernotomy or minithoracotomy. In the 141 patients, 62 valve, 42 coronary, 37 congenital heart, and 2 other procedures were successfully completed without conversion to full sternotomy. Preoperative chest x-ray, computed tomography, and/or magnetic resonance imaging were necessary for determining the level of ministernotomy, especially in aortic valve operations. Transthoracic echocardiography was useful for selecting procedures of mitral valve or intracardiac repair through the MICS approach. Intraoperative transesophageal echocardiography was essential for continuous monitoring of cardiac function, intracardiac flow, air bubbles, and so forth. The above results suggest that intensive imaging assessment might be very important for successful MICS operations with ministernotomy or minithoracotomy and that extensive indications for this technique exist for various cardiovascular diseases.
