Introduction And ObjectiveTranscatheter aortic valve implantation (TAVI) is an alternative therapeutic approach to patients not considered suitable for surgical aortic valve replacement (SAVR) due to their high operative risk. We sought to assess the impact of TAVI on the profile and operative results of patients with severe aortic stenosis undergoing SAVR.MethodsA total of 214 patients were included, of whom 103 consecutive patients underwent isolated SAVR in 2005 and 111 in 2009. Patients' demographic and operative data were collected retrospectively. Operative and one-year mortality and morbidity were analyzed.ResultsPatients' mean age was 70 years, and 56% were female. Following the introduction of a TAVI program, patients undergoing conventional surgery were older, with more comorbidities. Overall 30-day and one-year mortality were 2.8% and 7.0%, respectively. After the introduction of TAVI, the observed mortality rate for SAVR decreased, but not significantly (operative mortality: 3.9% before TAVI vs. 1.8% after TAVI, p = NS; one-year mortality: 10% vs. 4.5%, p = NS). Striking differences were observed in morbidity (operative morbidity: 23.3% before TAVI vs. 13.5% after TAVI, p = 0.047, and one-year morbidity: 20.4% vs. 9.9%, p = 0.032).ConclusionsSince the introduction of a TAVI program at our center, the number of patients undergoing SAVR has increased, with a slight rise in surgical risk, but without worsening the final operative results. The implementation of a TAVI program has thus had a positive impact on the volume of procedures, patient selection and outcomes in SAVR.Copyright © 2012 Sociedade Portuguesa de Cardiologia.
