Abstract
LUNA-GONZALEZ, Omar; HERNANDEZ-MEJIA, Benjamín I. and MARTINEZ-HERNANDEZ, Humberto J.. Negative predictors of major bleeding in postoperative aortic valve replacement via mini-thoracotomy. Rev. Colomb. Cardiol. [online]. 2024, vol.31, n.1, pp.39-47. Epub Mar 07, 2024. ISSN 0120-5633. https://doi.org/10.24875/rccar.23000069.
Introduction:
Aortic stenosis is the most common valvular heart disease requiring surgical treatment. Minimally invasive surgical techniques have emerged as alternatives to traditional median sternotomy.
Objective:
To analyze the possible risk factors associated with major bleeding in patients undergoing aortic valve replacement via right anterior mini-thoracotomy and to share the results found in our center.
Materials and methods:
A retrospective, observational, longitudinal study was conducted in patients undergoing right anterior mini-thoracotomy from July 2015 to December 2022. Demographic and clinical data, as well as relevant surgical and echocardiographic variables, were collected.
Results:
The mean age of the study population had a mean age of 58 years, with a predominance of men under 65 years of age. Only three patients experienced major bleeding 4.47%. Advanced age and extracorporeal circulation time (minutes) were associated with bleeding. No significant differences were found in other variables analyzed.
Conclusions:
The study results indicate a low rate of postoperative bleeding in minimally invasive surgery. Advanced age and prolonged extracorporeal circulation time were identified as significant risk factors for major bleeding. However, further studies with a larger sample size are needed to better understand these factors and the safety of minimally invasive surgery.
