Abstract 4375: Length of Stay and Reasons for Prolonged Length of Stay After Transcatheter Aortic Valve Implantation
Aims - Although transcatheter aortic valve implantation (TAVI) has been associated with encouraging short term outcomes, there is a paucity of data regarding in-hospital length of stay (LOS) and reasons of prolonged LOS. We assessed, therefore, the LOS and reasons for prolonged LOS after TAVI.
Methods - Between November 2005 and May 2009, we prospectively enrolled 95 consecutive patients in whom a CoreValve Revalving System aortic bioprosthesis was implanted. LOS was defined according STS definitions (short <6 days and prolonged >14 days) and reasons for prolonged LOS were recorded.
Results - Mean age was 81 +/− 7 years and mean Logistic EuroSCORE was 16 +/− 9. Procedural success was achieved in 93/95 patients (98%) (there were 2 intraprocedural deaths). In-hospital mortality was observed in 11%. In hospital adverse events included: CVA/TIA in 14 patients (15%), AMI in 1 (1%), vascular complications in 8 (8%), permanent pacemaker implantation (PPI) in 14 (15%) and infection in 11 (12%) (5 urinary tract, 3 access site and 2 pneumonia). Short LOS was documented in 4 patients (5%) and prolonged LOS in 22 patients (26%). In patients with either stroke, PPI or infection the mean LOS was significantly longer than those without these complications (16 (9) vs. 11 (9) p=0.028). Eight Patients (9%) were discharged to nursing homes, 6 (7%) were transferred to the referring hospital and 71 patients went home.
Conclusions - Following TAVI, a substantial proportion of patients have prolonged hospitalisation. This is predominantly explained by PPI, stroke and infection.
