Myocardial enzyme release in totally endoscopic coronary artery bypass grafting on the arrested heart.

Objective: Robotic totally endoscopic coronary artery bypass grafting enables coronary artery bypass grafting without sternotomy or thoracotomy. However, longer cardiopulmonary bypass and aortic endo-occlusion times are currently required compared with those of standard coronary artery bypass grafting operations. We investigated whether longer operation times affect the myocardial enzyme release and the postoperative course.

Evaluation of robotic coronary surgery with intraoperative graft angiography and postoperative multislice computed tomography.

Background: Robotically assisted totally endoscopic coronary artery bypass graft surgery (TECABG) is an innovative minimally invasive procedure requiring proof of immediate- and short-term patency of grafts to compete with conventional bypass surgery or percutaneous coronary interventions. The purpose of this study was to evaluate the combination of invasive and noninvasive coronary angiography methods in innovative cardiac surgery as an approach to optimal quality control.

Methods: In 86 patients after robotic coronary surgery (62 arrested-heart TECABG, 20 through sternotomy with robotically assisted anastomoses, 4 beating-heart TECABG), intraoperative coronary angiography was performed with a mobile C-arm.

Does preoperative multislice computed tomography predict operative times in total endoscopic coronary artery bypass grafting?

Objective: Multislice computed tomography (MSCT) is currently discussed as a potential tool for procedure planning in endoscopic heart surgery. We aimed to assess the influence of various thoracic measurements on operative times in arrested heart totally endoscopic coronary artery bypass grafting (AHTECAB).

Methods: 34 patients (aged 59 years, 71% male) scheduled for AHTECAB were examined prospectively with ECG-gated 16-channel MSCT angiography of coronary arteries and internal mammary arteries.
