Transfemoral Approach Balloon-expandable valves are deployed under rapid ventricular pacing at a rate of 160–220 bpm to minimize cardiac output and therefore minimize unintentional motion of the valve during balloon dilatation 高血压危险因素评估及防治新进展结核病防治临床技能竞赛防控部分培训老痴呆康复训练系统项目计划书雷替曲塞在结直肠癌肝转移及原发性肝癌介入治疗中的应用颅脑损伤和急性脑血管意外的急救护理麻疹疫情调查与处置技术指南 TAVI XIONGRAN 2014-11-25 QUIZ Street Avenue Street Avenue Hospital of UA Hospital of UA Hospital of UA Hospital of UA Summarize of TAVI Transcatheter aortic valve implantation (TAVI) It was introduced as an alternative treatment in patients with severe aortic valve stenosis(AS) Cribier A, Eltchaninoff H, Bash A, Circulation 2002;106:3006–3008. First Case of TAVI In 2002, Cribier et al demonstrated for the first time the feasibility of a percutaneous valve implantation in a patient with AS Providing a promising less invasive alternative treatment for valvular heart disease Cribier A, Eltchaninoff H, Bash A, Circulation 2002;106:3006–3008. two different TAVI devices are widely used the balloon-expandable Edwards SAPIEN Transcatheter Heart Valve the self-expanding Medtronic CoreValve? Both received CE Mark approval for European commercial sale in 2007 Edwards SAPIEN valve received FDA pre-market approval in the USA in November 2011 Two different TAVI devices Edwards balloonexpandable delivery systems CoreValve ReValving System ( a ) schemata and ( b ) following deployment with aortography Patients Selection Feasible in most patients with severe aortic stenosis Generally utilized in patients not suitable for surgical AVR, who are likely to derive functional and survival benefit? Two risk scores are used to calculate the risk of cardiac surgery “High-risk” surgical patients Having a Society of Thoracic Surgeons Predicted Risk of Mortality (STS-PROM) at 30 days of greater than 10% Logistic EuroSCORE of greater than 20 % Limited Do not account for several pertinent clinical risk factors, such as previous CABG, porcelain aorta, previous ches
