Background
The Ross procedure has demonstrated excellent long-term results, with restoration of life-expectancy in patients with severe aortic valve dysfunction. However, reintervention after Ross can occur, and herein we describe our center's experience with redo surgery after previous Ross procedures.
Methods
We searched our prospective database for aortic valve-repair and recruited all adult (≥18 years) patients who have undergone valve-sparing root replacements (VSRRs) and/or aortic valve-repair after Ross procedure between July 2001 and July 2022. Univariable logistic regression analysis was performed to identify variables affecting early mortality. Survival, freedom-from-valve-reintervention and freedom-from-aortic regurgitation (AR) grade ≥3 were analyzed with the Kaplan-Meier method.
Results
A total of 63 patients were recruited for this study. Indication for reoperation after Ross was aortic aneurysm without AR in 17 (27%), aortic aneurysm with AR in 27 (43%), and isolated AR in 19 (30%) patients. Median follow-up time was 7.82 years. The majority of patients (76%) had undergone the free root technique during their index Ross operation. Cumulative survival, after redo surgery following Ross, was 98.4% [95% confidence interval (CI): 89.3-99.8%] at 1 year, 96.3% (95% CI: 88.2-98.3%) at 5 years, and 92.4% (95% CI: 87.1-98.0%) at 10 years. Freedom-from-reoperation on the aortic valve at 1 year was 98.4% (95% CI: 97.0-99.8%), at 5 years was 96.7% (95% CI: 87.6-99.0%), and 79.7% (95% CI: 71.1-88.3%) at 10 years.
Conclusions
Long-term survival after redo surgery following the Ross operation is excellent. The data support our aggressive valve-sparing approach after Ross.
