Summary

Autograft dilatation is a common complication after the Ross operation. Early intervention and specific surgical techniques can reduce the risk of reoperation for aortic root dilatation.

Area of Science:

  • Cardiovascular Surgery
  • Cardiac Surgery Outcomes
  • Aortic Valve Repair

Background:

  • Autograft dilatation is a frequent late complication following the Ross operation.
  • Understanding its prevalence, consequences, and management is crucial for long-term patient care.

Purpose of the Study:

  • To define the prevalence, consequences, and management of autograft dilatation after the Ross operation.
  • To identify risk factors associated with autograft dilatation.

Main Methods:

  • A 10-year review of clinical experience involving 112 patients who underwent the Ross operation.
  • Cross-sectional echocardiographic follow-up was performed to assess autograft diameter and function.
  • End-points included freedom from autograft dilatation (diameter >4 cm) and reoperation for dilatation.

Main Results:

  • At 10 years, 29% of patients experienced autograft dilatation, with 6% developing aortic aneurysms.
  • Seven patients (22%) had moderate or greater autograft insufficiency.
  • Predictive factors for dilatation included preoperative aneurysm, root replacement technique, and absence of root buttressing.

Conclusions:

  • The incidence of root dilatation and reoperation is expected to increase with longer follow-up after the Ross operation.
  • Strategies like avoiding root replacement and employing root-stabilization measures may decrease late root pathology.
  • Early replacement of dilated autograft roots can potentially preserve the autologous pulmonary valve.
