Transcatheter 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. ⋯ Since 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.

Accurate risk stratification is an important step in the initial management of acute coronary syndrome (ACS), and current guidelines recommend the use of risk scores, such as the Global Registry of Acute Coronary Events risk score (GRACE RS). Recent studies have suggested that abdominal obesity is associated with cardiovascular events in patients with ACS. However, little is known about the additional value of abdominal obesity beyond risk scores. The aim of our study was thus to assess whether waist circumference, a surrogate of abdominal adiposity, adds prognostic information to the GRACE RS. ⋯ Abdominal obesity does not add prognostic information to the GRACE RS to predict six-month mortality or myocardial reinfarction.
