Objective:
This case report presents the successful application of transcatheter aortic valve replacement using the TaurusElite valve in a high-risk patient with severe calcified type 0 bicuspid aortic valve and aneurysmal dilation of the ascending aorta. The report highlights using a snare-assisted technique to navigate complex anatomical challenges.
Key Steps:
Preoperative multimodal imaging for precise anatomical assessment. A snare-assisted delivery system navigation ensures controlled passage through the aortic arch and valve. Balloon predilation and careful valve deployment at 2 mm above the annulus. Postdeployment confirmation of valve position and coronary perfusion.
Potential Pitfalls:
Risk of paravalvular leak due to severe calcification and asymmetric valve anatomy. Potential for coronary obstruction or aortic injury during valve deployment. Challenges in navigating a narrow aortic arch and aneurysmal dilation.
Take-Home Message:
TAVR with adjunctive techniques like snare-assisted navigation is a viable option for high-risk patients with complex BAV anatomy, emphasizing the importance of meticulous preoperative planning and precise valve positioning to minimize complications.
