Redo autograft operations after the Ross procedure.

Area of Science:

• Cardiovascular Surgery
• Thoracic Surgery
• Cardiac Valve Surgery

Background:

• Autograft dilatation is the primary cause of late autograft failure following the Ross procedure.
• Reoperation is often necessary to address autograft dysfunction.
• This study evaluates surgical techniques for reoperation, focusing on autograft sparing and composite root replacement.

Purpose of the Study:

• To assess the outcomes of reoperation for autograft dysfunction after the Ross procedure.
• To compare the effectiveness of autograft sparing techniques versus composite root replacement.
• To analyze long-term results of surgical interventions for late autograft failure.

Main Methods:

• Data were extracted from a prospectively collected registry of 160 patients who underwent the Ross procedure.
• Follow-up records and echocardiographic reports after reoperation were analyzed.
• Surgical procedures included autograft reimplantation, remodeling, composite root replacement (mechanical/biologic), and aortic valve replacement.

Main Results:

• Seventeen patients required reoperation for autograft dysfunction (dilatation with insufficiency in 16).
• At a median 5-year follow-up post-reoperation, 100% freedom from >2+ aortic insufficiency was observed in both reimplantation and replacement groups.
• No strokes occurred after autograft reimplantation; one late death was attributed to unrelated systemic lupus erythematosus complications.

Conclusions:

• Autograft valve reimplantation and composite aortic root replacement are effective treatments for aortic root dilatation and insufficiency post-Ross procedure.
• These techniques provide successful management of late autograft failure.
• Echocardiographic follow-up confirms reasonable short-term function after autograft preservation procedures.
