Application of valvuloplasty in mitral valve insufficiency in infants and small children / 中华实用儿科临床杂志

ABSTRACT

Objective@#To explore the efficacy of valvuloplasty on mitral valve regurgitation (MR) in infants and small children, in order to provide evidence for clinical treatment.@*Methods@#Retrospective analysis was conducted in patients aged less than 3 years old who have undergone mitral repair surgeries at Department of Cardiovascular Surgery, General Hospital of Western Theater Command from January 2015 to December 2017.Cardiopulmonary bypass (CPB) surgery was performed under general anesthesia.The corresponding repair operations were selected for various MR types.All the children were examined by cardiac ultrasound before discharge.Patients were followed up after surgery and mitral regurgitation was recorded.@*Results@#A total of 69 patients were enrolled, including 30 boys and 39 girls, with an average age of (19.3±11.6) months and an average weight of (9.6±2.1) kg.There were 32 cases of Carpentier type Ⅰ, 30 cases of type Ⅱ and 7 cases of type Ⅲ.Twenty-nine patients were diagnosed as simple MR, while the other 40 patients were combined with other cardiac malformations.One patient died at postoperative day 7.One patient still had severe MR after surgery, and then second operation was performed on the 10th day after first surgery.Sixty-five patients were followed up from 1 month to 3 years[(15.9±10.9) months]. During the follow-up period, no patient died or had reoperation.Aggravated MR was observed in 4 patients.@*Conclusions@#Mitral valvuloplasty is a safe and effective surgical method for treating infants and younger children with MR.The key to the success of surgery is to choose the appropriate individualized repair operation.At the same time, the growth potential of mitral valve should be fully considered to avoid restrained development.
