Abstract

Abstract: : OBJECTIVES: The Edwards Intuity valve is a rapid deployment aortic prosthesis that favours less invasive approaches. However, evidence about the clinical behaviour of their smaller sizes is scarce. Herein, we studied haemodynamic behaviours and clinical outcomes of small Intuity prostheses (19–21 mm) in comparison to larger Intuity prostheses (>21 mm). METHODS: This is an observational study including patients implanted with an Edwards Intuity rapid deployment aortic prosthesis. Patients with prosthesis sizes 19–21 and >21 mm were included. Baseline and perioperative variables, as well as adverse events during the follow-up were recorded and compared between groups. RESULTS: A total of 122 patients (37% female, mean age 75 ± 4.5 years) were included, of whom 54 (45%) were implanted with a small prosthesis and 68 (55%) with a prosthesis >21 mm. There were no significant differences between patients with small Intuity prostheses and patients with larger prostheses regarding in-hospital mortality (2% vs 4%, P = 0.43) or mortality during the follow-up (3.41 vs 2.45 per 100 patients-years; P = 0.58). Survival in the small Intuity valve group was 95% at 1 year and 83% at 6 years, whereas in the larger Intuity valve group was 96% at 1 year and 78% at 6 years. The presence of a small prosthesis did not influence mid-term survival (log-rank P -value = 0.62). CONCLUSIONS: This study showed good clinical performance of Intuity aortic prostheses with appropriate mid-term survival in patients with the small aortic annulus. Thus, the Edwards Intuity rapid deployment aortic prosthesis may be considered as a potential option in patients with the small aortic annulus. Abstract : Aortic stenosis is the most common heart valve disease in the developed world [1].
