- W3137481198 abstract "Abstract OBJECTIVES The purpose of this study was to review the outcomes of surgical treatment in patients with aorto-left ventricular tunnel and to investigate what kind of patient cohort is more likely to have adverse events. METHODS Twenty-one patients with a median age of 6.58 [interquartile range (IQR) 4.17–24.50] years who received surgical treatment of aorto-left ventricular tunnel from March 2002 to December 2019 were reviewed. The median follow-up time was 64.50 (IQR 25.15–120.50) months. Clinical characteristics, surgical methods and follow-up outcomes were summarized in separate groups of patients with or without preoperative aortic valve (AoV) issues. Composite adverse events were defined as death or requirement of reoperation. Time-related analysis of freedom from death and requirement of reoperation was performed with the Kaplan–Meier method. RESULTS The average tunnel size was 8.68 (standard deviation: 3.62) mm. The most common and the most important associated lesions were AoV lesions. Tunnels in 20 patients were closed with direct sutures or a patch. For 1 patient with an irreparable AoV, the tunnel was cut open simultaneously with aortic valve replacement and aortic root plasty. In the group of patients with preoperative AoV issues, 4 patients received aortic valve replacement with mechanical prosthetic valves and 6 patients received aortic valvuloplasty repair. The follow-up outcomes differed significantly between groups (the incidence of death was 15.38% and the incidence of requiring a reoperation was 46.15% in patients with preoperative AoV issues). In the group without preoperative AoV issues, there were no deaths and no reoperations (Fisher’s exact test; P = 0.018). The probability of freedom from death and of the requirement for reoperation between the 2 groups was not significantly different (log-rank, P = 0.09). Overall, the estimated probability of freedom from death and requirement of reoperation was 77.30% (standard error: 10.20%) [95% confidence interval (CI): 49.53–91.00] at 5 years, 67.64% (standard error: 12.70%) (95% CI: 36.71–85.84) at 10 years. CONCLUSIONS Patients with aorto-left ventricular tunnel with preoperative AoV issues are more prone to die or to require a reoperation. In contrast, patients without preoperative AoV issues can be free from death or reoperation for a longer period of time. Patients with preoperative AoV issues need much stricter postoperative long-term echocardiographic follow-up." @default.
