RESUMEN
INTRODUCTION: Transfemoral transcatheter aortic-valve implantation represents a therapeutic alternative for patients with severe aortic stenosis who cannot undergo surgery due to high surgical risk. OBJECTIVE: The aim of this study is to describe the anaesthetic procedure for transfemoral transcatheter aortic-valve implantation and the results on 100 patients with symptomatic severe aortic stenosis. MATERIAL AND METHODS: A series of cases are presented with prospective data collected on 100 consecutive patients. The anaesthetic procedure consisted of continuous remifentanil and propofol infusions, for sedation or general anaesthetic. RESULTS: Almost two-thirds (65%) of the cases ended on sedation, and 35% on general anaesthetic (19% out of this total were elective and 16% were due to complications during the procedure). Complications occurred in 34% of the cases, with both vascular and complete atrioventricular block being the most frequent. Mortality within the first 24h was 5%. CONCLUSIONS: Implantation of transfemoral aortic prosthesis under remifentanil-propofol sedation can be considered a valid therapeutic alternative for patients with severe symptomatic aortic stenosis, and with a high surgical risk, and therefore not considered for conventional surgery.
