Clinical research of reintervention for children with postoperative valve disease / 中华胸心血管外科杂志

ABSTRACT

Objective@#The purpose of this report was to discuss and evaluate the timing and outcome of reintervention for children with postoperative valve disease.@*Methods@#The clinical data of 139 patients with postoperative valve disease who received reintervention at SCMC from Sep. 2004 to Mar. 2019 were retrospectively analysed, including 85 males and 54 females. The age ranged from 8-175 months, and the weight ranged from 6.2-75.9 kg. With a mid-long term follow-up (2-133 months), the echocardiography result showed 40 cases of aortic valve disease, 49 cases of mitral valve disease, 32 cases of tricuspid valve disease and 18 cases of pulmonary valve disease. All patients underwent reintervetion treatment, the distribution of reintervention methods were shown as follow 47 cases of valve replacement, 40 cases of valvuloplasty, 23 cases of annuloplasty and 29 case of valve reconstruction.@*Results@#There were 6 in-hospital deaths with a mortality of 4.3%. The death cases included 2 cases of aortic disease, 2 cases of mitral disease, 1 case of tricuspid disease and 1 case of pulmonary disease. The early postoperative causes of death were acute myocardial failure, multiple organ failure and severe hyoxemia. Three delayed deaths occurred 8-26 months after operation because of cardiac insufficiency and cardiac shock. All survivors were under a follow-up of 4-148 months. The echocardiography showed the velocity of 92.3% valve stenosis patients had decreased significantly (P<0.05); the insufficient grades of 84.9% patients had reduced and maintained under morderate degree. 6 cases occurred aggravated insufficiency or stenosis and received reoperation in mid-term follow-up included 3 cases of aortic valve, 2 cases of pulmonary valve and 1 case of mitral valve. The cardiac function of survival patients has been improved after reintervtion, 83.1% patients maintained cardiac function at NYHA Ⅰ/Ⅱ at follow-up. The long-term survival rates of 4 valve disease were all over 90%.@*Conclusion@#The anatomical structure of chilidren’s valve is complicated and various, valve insufficiency and stenosis often occured after operation. The timing of reintervetion should focus on clinic symptom and cardiac function.The operation should be individually designed according to valve anatomy, which could effectly correct abnormal valve structure, promote cardiac function and improve living quality.
