Modified cardiopulmonary bypass circuit for transcatheter aortic valve implantation and emergent cardiac surgery.

Transcatheter aortic valve implantation (TAVI) has revolutionized the treatment of severe aortic stenosis in high-risk patients, offering a minimally invasive alternative to open-heart surgery. However, complications such as hemodynamic instability may require mechanical circulatory support. In some cases, emergent cardiac surgery may be required, necessitating a swift transition to cardiopulmonary bypass (CPB).
