HAMEAU, René et al. Minimally invasive balloon aortic valve valvuloplastyBackground. Rev Chil Cardiol [online]. 2022, vol.41, n.1, pp.19-27. ISSN 0718-8560.

Aortic balloon valvuloplasty (ABV) is a palliative procedure or a bridge to percutaneous or surgical aortic valve replacement. Our group proposes a minimalist approach that reduces the use of resources and also stands out for using larger balloons.


To assess the safety and the immediate results of patients undergoing aortic balloon valvuloplasty using a minimally invasive procedure.


All patients who underwent ballon aortic valvuloplasty (BAV) between July 2012 and Au- gust 2019 were included. The procedure was performed under conscious sedation using a single femoral access and without the installation of a temporary pacemaker. Success was defined as a 50% drop in the mean aortic gradient plus the absence of major complications.


52 procedures in 49 patients were performed; the average age was 76 ± 9,9 years. A third of patients included had a left ventricular ejection fraction ≤35% and a similar proportion had a high risk profile with an STS score> 10 points. A 28 mm balloon was used in 84.6% of cases. The procedure was successful in 94,2% of cases. There were 2 (3,85%) intraoperative deaths in very high-risk patients and 2 (3,85%) major vascular complications. The survival rate at late follow up was 32,7%.


Aortic balloon valvuloplasty with a minimally invasive technique using larger than usual balloons is a safe technique that achieves optimal hemodynamic results.
