HAMEAU, René et al. A minimalist approach for transcatheter aortic valve replacement. Rev Chil Cardiol [online]. 2019, vol.38, n.3, pp.173-181. ISSN 0718-8560.


In patients with symptomatic severe aortic stenosis, transcatheter percutaneous aortic valve implant (TAVI) is the standard treatment in those with intermediate or high surgical risk. The use of a minimalist approach has proven to be safe and effective, although there are no reports on the national reality


Descriptive study on the experience with patients undergoing TAVI implantation under a minimalist protocol at the Interventional Cardiology and Hemodynamics Unit of the Hospital Sótero del Río since January 2018. Clinical characteristics of the patients and the procedure were analyzed as well as intrahospital outcomes and at 30-days follow up.


Between January 2018 and April 2019, a total of 10 patients underwent TAVI implantation by transfemoral approach in our institution. The average STS-PROM score was 7.1. A successful implant was achieved in 100% of cases with an average residual gradient of 8 mmHg and no moderate to severe leak in any patient. There were no perioperative ischemic cerebrovascular events nor death in this group. A definitive pacemaker implant was required in 3 patients and one patient developed femoral hematoma that required red blood cell transfusion. The median hospital stay was 2 days.


The use of a minimalist strategy for TAVI implantation in our national reality is safe and applicable. Immediate results and at 30-days follow up were comparable to those described in international experiences.
