Age-related reoperation rate after the Ross procedure: a report from the German Ross Registry

Abstract

Background and aim of the study: An increasing number of young adult patients are choosing bioprostheses for aortic valve replacement (AVR). In this context, the Ross operation deserves renewed consideration as an alternative biological substitute. After both the Ross procedure and bioprosthetic AVR, reoperation rates remain a concern and may be related to age at surgery. Herein are reported details of freedom from reoperation after the Ross procedure for different age groups.

Methods: The reoperation rates of 1,925 patients (1,444 males, 481 females; mean age 41.2 ± 15.3 years) from the German Ross registry with a mean follow up of 7.4 ± 4.7 years (range: 0.00-18.51 years; total 12,866.6 patient-years) were allocated to three age groups: group I < 40 years; group II 40-60 years; and group III > 60 years.

Results: At 10 years (respectively 15 years) of follow up, freedom from reoperation was 86% (76%) in group I, 93% (85%) in group II, and 89% (83%) in group III.

Conclusion: There is some evidence that, at least during the first 10 and 15 years after AVR, the Ross procedure provides a significantly lower reoperation rate in young adult and middle-aged patients aged < 60 years. This information may be of interest to the patients' or physicians' decision-making for aortic valve surgery.
