Introduction:

severe aortic stenosis is frequent and valve replacement is the only effective treatment. Percutaneous aortic valvuloplasty has transient benefits, and its indication is restricted to unstable patients as a bridge to other treatment or palliative therapy. In our country, there is a few evidence of this technique.

Objective:

to determine the indication, efficacy, complications and mortality of percutaneous aortic valvuloplasty performed in our center between January 2006 - September 2018. Secondarily, to determine which was the definitive therapy and it´s delay.

Method:

retrospective and descriptive study. All patients who received valvuloplasty during the study period were included. Clinical histories were reviewed. Qualitative variables were presented in absolute value and percentage; the quantitative ones, in median and interquartile interval. Wilcoxon test was applied to dependent variables, p <0.05. Kaplan Meier curves were performed to analize survival. Protocol was approved by ethics committee.

Results:

28 cases. 17 (60.7%) were female. Average age was 79.5 years (IQ 73-85.5). The objective of percutaneous aortic valvuloplasty was bridge therapy to decision in 11 cases (39.2%), bridge to definitive treatment in 12 (42.8%) and palliative in 5 (18%). The most frequent indications were: refractory heart failure in 10 cases (35.7%) and cardiogenic shock in 9 (32.1%). Valvuloplasty was successful in 57.1% of cases. 19 patients died (67.8%). The median survival was 59 days (IQ 5-412). 6 patients received definitive treatment (4 percutaneous implantation and 2 open cardiac surgery). The time from percutaneous aortic valvuloplasty to percutaneous aortic valve implantation was 233 days and 47 days to open surgery.

Conclusions:

the most frequent indications for percutaneous aortic valvuloplasty were bridge therapy to definitive treatment and decision. Percutaneous aortic valvuloplasty was successful in more than 50% of cases. Major complications determined the prognosis. Mortality was high at follow-up. A small number acceded to definitive treatment (predominantly percutaneous implantation).
