Transfer from a regional site for res- cue angioplasty was strongly associated with male gender, lower age (60) and higher mortality (27%). Average time from symptoms to balloon time was 202 minutes and time from symptoms to treatment was also associated with mor- tality. Conclusion: Age is a factor in survival from AMI as is time from symptom onset to treatment. Despite the age disparity between genders groups women were under- represented in this group and more work needs to be undertaken to rectify this imbalance. doi:10.1016/j.hlc.2011.05.282 280 A Single Centre Experience in the Use of Rotational Atherectomy for the Percutaneous Management of Coro- nary Artery Disease F. Syed ∗ , E. Vink, K. Poon, M. Savage, M. Pincus, A. Small, N. Bett, R. Chua, D. Walters, O. Raffel Department of Cardiology, The Prince Charles Hospital, Australia Background: Rotational atherectomy (RA) remains a valuable tool in the management of certain coronary lesions which due to complex morphology and calci- fication cannot be successfully treated with standard percutaneous coronary intervention (PCI). Method: We performed a retrospective analysis of con- secutive patients who underwent RA in our centre from January 2007 till February 2011. Clinical characteristics, angiography findings, procedural outcomes and compli- cations were assessed. Results: Fifty-four procedures were included. Forty-five (83%) were males. Most patients had multiple coronary artery disease risk factors. Procedural success rate was 89% with a low rate of major complications related to the procedure (see below): • PCI indication Angina 39 (72.2%) Myocardial infarction (MI) 23 (42.6%) • RA indication Complex lesion 42 (77.8%) Previous PCI failure 12 (22.2%) • Success rate 48 (88.9%) • Complications Death (unrelated to procedure) 1 (0.02%) MI (unrelated to procedure) 3 (0.06%) Stroke 1 (0.02%) Acute kidney injury 1 (0.02%) Access-site bleeding 10 (18.5%) Conclusion: RA remains a useful adjunct to PCI in the management of, In carefully selected cases complex cal- cified coronary lesions can be treated with a high success and low complication rate. doi:10.1016/j.hlc.2011.05.283 281 Accurate Assessment of the Femoro-iliac Arteries for TAVI Using On Table Dyna CT J. Crowhurst ∗ , D. Campbell, B. Robinson, K. Poon, C. Aroney, D. Walters The Prince Charles Hospital, Australia Background: Trans-catheter Aortic Valve Implantation (TAVI) requires adequate femoral access via the Femoro- iliac arteries. Femoro-iliac assessment is an important phase of the TAVI work-up. An aorto-iliac angiogram per- formed in the PA position to assess the calibre of the arteries is the gold standard. A computed tomography (CT) scan of the femoro-iliac arteries can also be per- formed. On table C-arm CT (DYNA CT) has been shown to image other areas of the body effectively. This study aimed to compare the effectiveness of on table C-arm CT of the pelvic area with traditional CT and the angiogram. Method: Eight patients selected for TAVI work-up had an aorto-femoral angiogram, an on table Dyna CT (Siemens Artis Zee) of the pelvic area and a traditional pelvic CT scan (Siemens definition) performed as part of their work- up. We compared the calibre of the femoro-iliac arteries at their Minimum luminal diameter using all three tech- niques. Results: In all eight patients, the DYNA CT scan pro- duced diagnostic axial CT images. In all eight patients, the measurements of the calibre of the femoral artery were within 5% of the traditional CT scan (P = 0.002) and 5% of the aorto-iliac angiogram (P = 0.002). Conclusion: C-arm CT (Dyna CT) can be used to accu- rately assess the femoro-iliac arteries in TAVI patients during their work-up angiogram. This negates the need for the femoral angiogram and separate pelvic CT scan. doi:10.1016/j.hlc.2011.05.284 282 This abstract has been withdrawn. 283 Aortic Valve Guide—Automatic Valve Annulus Profiling For TAVI. First Australian Experience J. Crowhurst ∗ , D. Campbell, B. Robinson, K. Poon, C. Aroney, D. Walters The Prince Charles Hospital, Australia Background: Both ‘Corevalve’ and the ‘Edwards’ valves require the prosthesis to be accurately placed in the prox- imal ascending aorta. The valve must be profiled perfectly perpendicular to the X-ray beam before deployment. Per- forming an on-table CT scan (Cardiac Dyna CT) has been shown to effectively demonstrate the correct C-arm angle for placement of the valve in over 95% of cases but requires some post processing/image rendering.
