Aims: Transcatheter aortic valve implantation (TAVI) is the preferred treatment modality for patients with severe aortic stenosis at high or prohibitive risk for surgical aortic valve replacement (SAVR). We aimed to evaluate real-world outcomes after treatment according to the decisions of the multidisciplinary heart team in a Belgian health-economic context. Methods and results: Four hundred and five high-risk patients referred to a tertiary centre between 1 March 2008 and 31 December 2015 were screened and planned to undergo SAVR, TAVI or medical treatment (MT). ⋯ SAVR (9[6-14] and 16[12-22] days; p < .001). Conclusions: Limited resources for transcatheter valve therapies in Belgium push a significant number of patients to SAVR, while TAVI in even higher risk patients translates into similar outcomes and shorter hospital stay. These findings underscore the need for broadening indications for TAVI, as well as readjustment of the budgetary allocations for hospitals in Belgium.

Background: To explore the prognostic value of combination of coronary artery calcium scoring (CACS) and single-photon emission computed tomography (SPECT) on the long-term risk of major adverse cardiac events (MACEs) in Chinese patients at low risk of suspected coronary artery disease (CAD). Methods: The medical records of 1876 adult patients who were referred for clinically indicated non-invasive CAD detection with SPECT/CT from January 2011 to December 2013 were retrospectively reviewed. The primary outcome was the occurrence of MACEs, including cardiac death, non-fatal myocardial infarction (MI), unstable angina (UA), and late revascularisation. ⋯ Moreover, interaction terms for CACS and SPECT findings were reported to be significantly associated with MACE outcomes (p < .01). Conclusions: CACS and SPECT provided both independent and compensatory prognostic information for risk of MACE in patients at low risk of suspected CAD. Our findings strongly support adding a CACS testing in addition to SPECT in asymptomatic patients to better define the risk of cardiac events during follow-up.
