Intra vascular lithotripsy facilitated Transfemoral TAVR
Abstract
Transcatheter aortic valve replacement (TAVR) is now the standard of therapy for elderly population with severe aortic stenosis. Several studies have established that the outcomes of TAVR are superior when compared with Surgical aortic valve replacement (SAVR), especially when the access route is transfemoral arterial approach. In the elderly population with advanced age and numerous comorbidities, iliofemoral arterial disease (IAD) is not uncommon and it precludes the use of this route for TAVR. Peripheral Intravascular lithotripsy (IVL) has been previously established as an excellent safe and efficient modality to treat symptomatic occlusive calcific iliofemoral artery disease. The same principle of IVL has been recently used successfully to modify the vascular compliance of heavily calcified iliofemoral arteries thereby enabling large bore sheath advancement and safe passage of TAVR delivery catheter systems.We report the first case of Intravascular lithotripsy facilitated Transfemoral TAVR (TF-TAVR) in India. This case was done in December 2020 by the “femoral route” in order to keep the TAVR procedure simple straightforward and discharge the patient back home quickly in Covid times. The use of Intravascular Lithotripsy (IVL)was based on evidence of good outcomes in trials of peripheral vascular disease of lower limbs as well as from the good outcomes of few registries on IVL facilitated TAVR.1,2,3,4,5,6,8 The second case was done in August 2021 by us for another patient successfully.
