Resumen

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.  http://dx.doi.org/10.4067/S0718-85602022000100019.

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.

Aim:

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

Methods:

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.

Results:

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%.

Conclusion:

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