Whilst sutureless valves is in principle based on a similar technology to TAVI prosthesis, the former does not require crimping of the pericardium. The sutureless surgical approach provides direct visualization of the implantation and target orifice location, in contrast to TAVI where visualization is achieved indirectly via the use of fluoroscopy. Current TAVI protocols do not involve excision of the diseased calcified aortic valve, in contrast to SU-AVR. Furthermore, calcium remove in sutureless aortic valve surgery may be effective in reducing brain embolic showers and injuries in comparison to TAVI, however, this hypothesis remains to be demonstrated in clinical studies.
