Table 1 Choice of access route
Factors favouring TS approach (predominantly Evolut R) | Factors favouring TA approach (exclusively SAPIEN) |
|---|---|
Favourable subclavian artery anatomy | No apical left ventricular aneurysm or thrombus |
Aortic annulus angulation < 70° (left subclavian) or < 30° (right subclavian) | No severe aortic annuluar calcification |
No pedicled internal mammary coronary artery bypass graft | Low probability of native coronary artery occlusion (adequate coronary sinus width and coronary artery height) |
