ALVAREZ TAMARA, Carlos et al. Minimally Invasive Surgery with the Bentall-De Bono Technique. Initial Experience at Hospital Italiano de Buenos Aires. Rev. argent. cardiol. [online]. 2023, vol.91, n.3, pp.220-224. ISSN 1850-3748.


: Cardiac surgery avoiding full sternotomy began to emerge in the 1990s with the first hemi-sternotomies and mini-thoracotomies. Aortic valve and root surgery is one of the most common procedures in our field. In this paper, we analyze our experience in minimally invasive cardiac surgery (MICS) for the aortic root with the Bentall-De Bono technique (MICS-Bentall).


: To analyze the surgical results in the first 10 patients underwent a MICS-Bentall procedure at our site.

Materials and Methods

: A retrospective observational study was carried out including patients with valve disease and aortic root dilation who underwent a surgery with the MICS-Bentall procedure in a tertiary care hospital from December 2019 to December 2020. Continuous variables were expressed as mean and standard deviation or median and interquartile range according to the observed distribution. Categorical variables were expressed as absolute and relative frequency.


: Out of 165 patients undergoing aortic root surgery, 10 patients were included. Mean age was 56 ± 17.03 years, 70% male; all cases were elective. Median (interquartile range, IQR) STS PROM % was 1.48 (1- 2.02). Eighty percent had bicuspid valve. Fifty percent of patients were extubated within 6 hours. In the 30-day follow-up, no death was recorded, and two complications were registered: one patient experienced atrial fibrillation without hemodynamic decompensation and another a wound infection. The mean hospital length of stay was 5 days.


: In our experience, MICS using the Bentall technique showed satisfactory results in terms of low perioperative mortality, early extubation, and short hospital stay.
