Trans catheter aortic valve implantation(TAVI ) is gaining acceptance as an alternative to surgical aortic valve replacement .It has successfully negotiated the initial hurdles and entered the clinical domain . More and more patients receive this modality as the expertise and hardware show consistent improvement.
Although TAVI is limited to patients in high risk category for surgery , it is expected to make in roads into intermediate risk patients as well and pose a real threat to cardiac surgeons in the years to come .
The only point surgeons can rejoice is , it cannot be implanted in patients with aortic regurgitation as of now.

Thank you NEJM .
