Key result
Minimally invasive Bentall-De Bono surgery yields 0% 30-day mortality with a 5-day stay.
Why the study?
To analyze institutional experience and surgical results in the first 10 patients undergoing minimally invasive cardiac surgery for the aortic root using the Bentall-De Bono technique.
Observational (n=10)
No
Minimally invasive aortic root surgery using the Bentall-De Bono technique appears safe and feasible, yielding low early mortality and short hospital stays in selected patients.
Background: Cardiac surgery avoiding full sternotomy began to emerge in the 1990s with the first hemi-sternotomies and minithoracotomies. 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). Objective: To analyze the surgical results in the first 10 patients underwent a MICS-Bentall procedure at our site. 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. Results: 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.

Tamara et al. (2023) conducted an observational in Valve disease and aortic root dilation (n=10). Minimally invasive cardiac surgery (MICS) with the Bentall-De Bono technique was evaluated on 30-day mortality. Minimally invasive cardiac surgery with the Bentall-De Bono technique resulted in 0% 30-day mortality and a mean hospital length of stay of 5 days.
