Intraoperative TAVI Valve Usage for Heavily Calcified Redo Operation
Case description
In cases of severely calcified aortic annulus where conventional valve replacement poses high risk of annular rupture or technical failure, the intraoperative use of a transcatheter aortic valve implantation (TAVI) device during open-heart surgery offers a safe and effective alternative. This hybrid approach allows for precise deployment of the TAVI valve under direct vision and cardiopulmonary bypass, eliminating the need for extensive decalcification and minimizing trauma to the fragile annulus. It is particularly beneficial in elderly or high-risk patients with hostile aortic roots, where traditional valve suturing may not be feasible. The procedure ensures hemodynamic stability while preserving structural integrity, making it an important tool in complex aortic valve surgeries.
