Sumario: | Purpose: To discuss minimally invasive cardiac surgery aortic valve replacement (MICS-AVR) approach via anterior thoracotomy using continuous retrograde cardioplegia. Continuous retrograde cardioplegia facilitates excellent continuous homogeneous cooling of the heart during cardiac arrest. Methods: We performed AVR using the proposed method in nine patients between June 2018 and September 2019. The median age of the patients was 73 (range: 43–84) years. The pleural space was entered via anterior thoracotomy. After opening of the right atrium, a retrograde cardioplegic cannula was inserted into the coronary sinus with a purse-string suture. Continuous cold blood retrograde cardioplegia was initiated at 700 mL/h. Results: Extubation in the operating room was performed in five (56%) patients. No new decreased function of the left and right ventricles was observed in intraoperative transesophageal echography or transthoracic echocardiogram. Conclusion: MICA-AVR through continuous retrograde cardioplegia is a safe technique. |
