Comparative Study Between Complete Ultrasound Guidance and Radiation Guidance in Percutaneous Balloon Pulmonary Valvuloplasty / 中国循环杂志

ABSTRACT

Objective:To evaluate the safety and efficacy of ultrasound guidance for percutaneous balloon pulmonary valvuloplasty (PBPV) in comparison with conventional X-ray guidance.Methods:Our research included in 2 groupsUltrasound group,n=102 patients with PBPV under ultrasound guidance in our hospital from 2013-03 to 2016-08 and X-ray group,n=280 patients with PBPV under traditional X-ray guidance in our hospital at the same period of time.Post-operative effect was evaluated by echocardiography and compared between 2 groups.Results:The patients' age,body weight,pulmonary artery diameter,immediate post-operative pulmonary transvalvular pressure gradient (PTPG),the in-hospital time and cost were similar between 2 groups,P＞0.05.The success rate of operation in Ultrasound group and X-ray group was 99.0％ vs 100％,P=0.267.In the ultrasound group,1 patient was converted to a conventional surgery due to right ventricular outflow tract muscle spasm after dilation.The operation time in X-ray group was longer than Ultrasound group,(38.9±9.2) min vs (34.6±10.0) min,P＜0.001.The X-ray exposure time was (3.9±1.2) min in X-ray group.The mean follow-up time was (25.5±13.2) months and PTPG in Ultrasound group and X-ray group were (16.2±4.3) mmHg and (15.3±4.5) mmHg,P=0.120.No serious complications as death,peripheral vascular injury,cardiac perforation and pericardial effusion occurred in either group.Conclusion:PBPV under complete ultrasound guidance may not only avoid radiation and contrast agent,but also keep the safety and efficacy of minimally invasive conventional percutaneous interventional treatment.
