ABSTRACT

BACKGROUND:

Aortic valve sparing surgery (AVS), in combination with aortic cusp repair (ACR), still raises many questions about the increased surgical complexity and applicability for patients with pure aortic valve regurgitation (AR). The aim of this study was to investigate our long-term outcomes and predictors of recurrent AR (> 2+) after AVS and reconstructive cusp surgery.

METHODS:

We reviewed data of 81 patients who underwent AVS (a reimplantation technique) with concomitant ACR for AR and or dilatation of the aortic root at our institution during the period from April 2004 to October 2016. On preoperative echocardiography, the majority of the patients, 70 (86.4%) presented with severe AR grade (> 3+) and 28 (34.5%) of the patients had the bicuspid phenotype. Time to event analysis (long-term survival, freedom from reoperation, and recurrence of AR > 2+) was performed with the Kaplan-Meier method. Multivariate Cox regression risk analysis was performed to identify independent predictors of recurrent AR (> 2+). The mean follow-up was 5.3 ± 3.3 years and 100% complete.

RESULTS:

The in-hospital (30-day) mortality rate after elective surgery was 1.2%. The overall actuarial survival rates were 92.9 ± 3.1% and 90.4 ± 3.9% at five and 10 years, respectively. Actuarial freedom from recurrent AR (> 2+) was 83.7 ± 4.5% within the cohort at five and 10 years. The cumulative freedom from all causes of cardiac reoperation was 94.2 ± 2.8% within the cohort at 10 years. Neither bleeding nor thromboembolic or permanent neurologic events were reported during follow-up. By multivariate analysis, independent predictors of reccurent AR (> 2+) were an effective height lower than 9 mm (p= 0.02) and intraoperative residual mild AR (p= 0.0001).

CONCLUSIONS:

AVS with ACR, combined in a systematic fashion, is a safe and reproducible option with low risk of long-term valve related events and normal life expectancy for patients with pure aortic regurgitation. The competent aortic valve and effective height, not lower than 9 mm intraoperatively, are mandatory to achieve long-lasting AV competency.
