(DEB) deployment in the management of in-stent restenosis (ISR). Methods and Results: Eighteen patients with ISR totalling 28 lesions were treated with DEB following rotablation between December 2010 and November 2014. The mean age was 66.3 years (range 18-80). 83% of patients were male and 33% diabetics. The vessel treated was the circumflex in 39%, RCA in 25%, LAD in 22%, intermediate in 7% and diagonal in 7%. Lesion complexity was 50% type B2, 39% type C, and 11% type B1. Lesions were long (>20mm) in 14%, CTOs in 4% and bifurcational in 61%. The average lesion length was 13.6mm. Device failure occurred in 4% due to inability to deliver the DEB to the target lesion (n=1). On hospital discharge 89% of patients were on aspirin, and 89% on clopidogrel. Mean and median follow-up were 16 months and 24 months respectively, with 12 and 24-month follow-up in 83% and 56%. There were no cases of death or myocardial infarction during followup or in hospital. Target lesion failure occurred in two lesions (7%) in a circumflex bifurcation. ISR in this bifurcation was recurrent despite five treatments with rotablation and DEB, three to the main vessel and two to the side branch. There were no other instances of target lesion failure. Conclusion: Experience at our centre suggests that DEB following routine rotablation may be a safe and effective treatment option for in-stent restenosis in most cases. http://dx.doi.org/10.1016/j.hlc.2015.06.441 441 Safety and efficacy of transcatheter aortic valve implantation compared with surgical aortic valve replacement in older high-risk patients with severe aortic stenosis - a single centre study V. Wilson ∗ , T. Wong, P. Tamuno, S. Pasupati, R. Nair Waikato Hospital, New Zealand Introduction: Transcatheter Aortic Valve Implantation (TAVI) is a viable alternative for patients with aortic stenosis (AS) deemed unsuitable for surgical Aortic Valve Replacement (sAVR). Older patients with high clinical risk undergo sAVR after subjective assessment. Objective: Compare in-hospital recovery time and outcome for high-risk patients undergoing sAVR vs. TAVI from January 2010 to February 2014 at a New Zealand regional centre. Methods: Retrospective data was collected for patients undergoing TAVI (trans-femoral / subclavian) and patients over 75 years of age undergoing sAVR from January 2010 February 2014 at Waikato hospital. Length of hospital stay (LOS) during index admission, 30-day and 1-year mortality were analysed for TAVI and sAVR patients risk stratified based on Logistics Euroscore (≥12). Results: There was no significant difference in age (79±7 v 80±3 years) or gender distribution (34% v 39% females) between TAVI (n=90), and high-risk sAVR (n=71) groups. Compared with TAVI, high-risk sAVR group had longer LOS (5.6±2.5 v 8.5±4.4 days, p < 0.0001) and increased mortality at 30 days (3% v 8.4%) and 1 year (11% v 14%). LOS was longer

High-risk sAVR had older patients compared to lowrisk sAVR group (80.6±3.8 v 79±3 v, p = 0.001) with higher mortality at 30 days (8.4% v 2%) and 1 year (14% v 6%). Conclusion: sAVR is ideal for low-risk patients. TAVI is safer for older patients with higher clinical risk.
Conclusion: Despite the significantly higher radiation and fluoroscopy used in complex PCI, operator exposure was not significantly higher. http://dx.doi.org/10.1016/j.hlc.2015.06.444
