[Transcatheter aortic valve replacement after Ozaki procedure].

Area of Science:

• Cardiovascular Surgery
• Interventional Cardiology
• Biomaterials in Medicine

Background:

• The Ozaki operation, a neocuspidalization technique for aortic valve defects, shows mid-term success but carries risks of neocusp rupture and endocarditis leading to aortic insufficiency.
• Transcatheter aortic valve replacement (TAVR) is an evolving minimally invasive treatment for aortic valve disease, increasingly used across various surgical risk categories.
• Redo cardiac surgeries, especially after previous valve interventions, present heightened risks of complications.

Observation:

• A clinical case report details a patient who developed aortic insufficiency two years post-Ozaki procedure.
• The patient underwent successful transcatheter aortic valve prosthesis implantation.
• Technical aspects and immediate outcomes of this transcatheter intervention were documented.

Findings:

• Successful transcatheter aortic valve implantation was achieved in a patient with aortic insufficiency following the Ozaki procedure.
• This case demonstrates the feasibility of TAVR as a treatment option for complications arising from neocuspidalization.
• Immediate outcomes indicate a positive result for this complex patient scenario.

Implications:

• Transcatheter aortic valve replacement can be a viable and potentially safer alternative to repeat open-heart surgery for managing aortic insufficiency after the Ozaki procedure.
• This approach expands treatment options for patients with degenerated or malfunctioning neocusps, particularly those at higher risk for conventional redo surgery.
• Further research into long-term outcomes of TAVR in post-Ozaki patients is warranted to establish its role in managing late complications.
