Description
Koushik Kondapi and colleagues report a 2026 high-risk valve-in-valve replacement in a man with chronic type B aortic dissection. Valve replacement through a catheter is already tricky when chronic dissection is present, given the risk that the procedure extends the tear. The patient was a 45-year-old man with a repaired type A dissection, a prior aortic valve replacement, and residual type B dissection, who arrived in cardiogenic shock from severe prosthetic valve narrowing.
Because surgical risk was high and he was deteriorating fast, the team performed valve-in-valve replacement successfully, and the shock resolved. Femoral access needed special care to ensure entry into the true lumen of the dissected aorta. The case shows that valve-in-valve replacement can work even in acute deterioration with type B dissection.
