Abstract
Objective: To evaluate the criteria for patient selection in minimally aortic valve replacement through right anterior thoracotomy (AVR-RAT) based on computed tomography scan. Subject and method: Collect CT images of the aorta of 14 patients undergoing AVR-RAT in Ha Noi Heart Hospital from October 2019 to June 2020. Analyzing image characteristics associated to surgery and three criteria of the author Glauber M and colleagues had introduced. Result: The number of rightward aortas were 2/14 (14.3%), the distance from the aortic to the sternum not exceed 10cm 4/14 (28.6%), the inclination of the aorta to greater than 45° 7/14 (50%); no patients have achieved all 3 criteria. The majority (12/14 - 85.7%) of aortic valve was viewed directly (perpendicularly) from the second intercostal space, and 100% of normal aortic clamp position was at the level of the second and third intercostal space. Conclusion: The patient selection criteria of Glauber et al based on computed tomography scan in AVR-RAT has weak application in practice and be only for references. The incision through the second intercostal space, which can extend down to the third intercostal space, is reasonable in most cases of AVR-RAT.
