2 Available systems: Edwards (TA and TF) and Core valve.

3 INTRODUCTION 3 4% 0f > 65 y % of elderly denied surgery,. TAVI is an alternative.

4 pt 1. Aortic valve area: < 1 cm 2 (<0.6 cm 2 /m 2 ) 2. Aortic valve annulus diameter: 20 mm and 27 mm, 18 mm 24mm 3. Ascending aorta: 43 mm AND 4a. Age 70 yrs OR 4c. Age 65 yrs and 1-2 comorbidities 4b. Logistic ES 15% OR

5 CONTRINDICATIONS General For transfemoral approach For the transapical approach 1. Aortic regurgitation 2. Aortic annulus <18 or >25 mm for balloon expandable and <20 or >27 mm for selfexpandable devices 4. Bicuspid aortic valve 5. Present of asymmetric heavy valvular calcification 6. Aortic root dimensions >4.5 cms 7. Presence of apical left lf ventricular thrombus 8. Evidence of acute myocardial infarction <30 days 9. Hypertrophic cardiomyopathy 10. Life expectancy <1 year due to non cardiac causes 1. Iliac arteries with severe calcification tortuousity and small diameter (6 9 mm), previous aorto femoral bypass 2. Severe angulation of aorta and atheroma of the outcome andcoaptation coaptation, aneurysmof the abdominal aorta with mural thrombus 3. Presence of bulky atherosclerosis of the ascending aorta and arch 1. Previous surgery of the left ventricle using a patch such as the Dor procedure 2. Calcified pericardium 3. Severe respiratory insufficiency

34 No case is easy or straight forward CONCLUSION TAVI can be done with reasonably low M & M, however, we are dealing with very high risk patients, approach should be through multidisciplinary approach. Patient selection remains a learning curve. The trans apical approach is very simple BUT requires a minithoracotomy. The transfemoral approach is technically moredifficult but has advantages if the peripheral complication rate can be minimised and sheath size is reduced This is a major technology breakthrough, it's the future remain to decided. ( like PCI & stents)
