The optimal technique for myocardial protection and cardioplegia delivery during totally endoscopic robotic surgery is still under evolution. Cardioplegia delivery with endovascular clamping of the aorta is a common method used for this purpose but has several disadvantages and may lead to serious complications. Here we describe an alternative cardioplegia delivery method during totally endoscopic atrial septal defect closure and mitral valve repair. The method using a transthoracic aortic clamp and an antegrade cardioplegia cannula without any thoracotomy seems to be a safe and reproducible technique, which may enhance myocardial protection and prevent some of the complications of the endoclamp technique during robotically assisted cardiac surgery.

We conducted a high-risk redo mitral valve replacement through a right mini-thoracotomy without rib spreading (redo-MICS MVR) under systemic hyperkalemia combined with circulatory arrest to circumvent complications associated with cardioplegia delivery. The patient, a 75-year-old man, had a predicted mortality rate of 20%. Initial antegrade cardioplegia successfully induced cardiac arrest, which was administered every 30 min.

Material And Methods: We measured the main metabolic parameters using indirect calorimetry in 20 patients after on-pump cardiac surgery with cardioplegia. To evaluate the impact of metabolic load on CO, VO and DO, we administered dobutamine 3 µg/kg/min at the second phase of the study.

A 59-year-old male underwent Bio-Bentall + total arch replacement with a frozen elephant trunk for acute type A aortic dissection before at another hospital. He was diagnosed as mediastinitis and previous graft infection, followed by wound closure with omental flap installation. However, the recurrent graft infection from the aortic root to the FET in the descending aorta was diagnosed by 18-fluorodeoxyglucose positron emission tomography.
