Clinical outcome of tricuspid valve replacement in children aged no more than 14 years / 中国胸心血管外科临床杂志

ABSTRACT

@#Objective    To summarize the clinical characteristics and outcome of tricuspid valve replacement (TVR) in children aged no more than 14 years, and to discuss the selection of prosthesis. Methods    From September 2002 to August 2019, 14 patients aged no more than 14 years who received TVR were included in our study. There were 9 males and 5 females, with a mean age of 9.8±4.3 years. Results    Mechanical prosthesis was implanted in 8 patients, and bioprosthesis in 6 patients. The mean cardiopulmonary time and aortic-clamp time was 170.3±109.8 min and 95.1±63.1 min, respectively. The mortality within 30 days after surgery was 21.4% (3/14), and all 3 patients died of severe low cardiac output syndrome. Eleven patients were followed up for 34-199 (100.1±57.4) months. During the follow-up, mechanical prosthesis dysfunction occurred in 3 patients, 2 of whom received secondary TVR. One patient died during the follow-up. Conclusion    The bioprosthesis is the first choice for TVR in children. Some long-term complications may occur after TVR, and close follow-up and timely intervention are needed.
