Long-term outcomes and predictors of recurrent aortic regurgitation after aortic valve-sparing and reconstructive cusp surgery: A single centre experience
Journal of Cardiothoracic Surgery Nov 24, 2019
Karciauskas D, Mizariene V, Jakuska P, et al. - By analyzing data from patients (n = 81) who were treated with aortic valve sparing surgery (AVS) (a reimplantation technique) with concomitant aortic cusp repair (ACR) for aortic valve regurgitation (AR) and or dilatation of the aortic root at a single centre from April 2004 to October 2016, researchers analyzed long-term outcomes as well as predictors of recurrent AR (> 2+) following AVS and reconstructive cusp surgery. Following elective surgery, the in-hospital (30-day) mortality rate was identified to be 1.2%. At five years, the overall actuarial survival rates were estimated to be 92.9 ± 3.1%, these were 90.4 ± 3.9% at 10 years. Within the cohort, actuarial freedom from recurrent AR (> 2+) was found to be 83.7 ± 4.5% at five and 10 years. Findings revealed the safety as well as the reproducibility of AVS with ACR, combined in a systematic fashion, as a choice that offered low risk of long-term valve-related events as well as normal life expectancy for patients with pure aortic regurgitation. In order to obtain long-lasting aortic valve competency, the necessary factors are a competent aortic valve and effective height, not lower than 9 mm intraoperatively.
