ABSTRACT
Objective To evaluate the application of echocardiography in guiding percutaneous balloon pulmonary valvuloplasty in children and to summarize the key echocardiographic planes used in the procedure Methods From February 2013 to September 201 5 38 isolated congenital pulmonary valve stenosis patients were recruited Case inclusion criteria age ≥3 years old purely congenital pulmonary valve stenosis and pulmonary transvalvular pressure gradient ≥40 mmHg Echocardiography was used to assess the severity of pulmonary valve disease and to measure pulmonary transvalvular pressure gradient before procedure Intraoperative transthoracic or transesophageal echocardiography was used to monitor the whole process of percutaneous balloon pulmonary valvuloplasty and to evaluate immediate postoperative efficacy of the procedure All patients were followed up by echocardiography after a month post-discharge Results Thrity eight cases were successfully treated by echocardiography-guided percutaneous balloon pulmonary valvuloplasty The average age of children was 7 1 ±2 5 years mean body weight was 25 3 ±7 1 kg Before the procedure pulmonary transvalvular pressure gradient was 65 9 ± 8 9 mmHg pulmonary annular diameter was 14 6±1 1 mm Immediate postoperative pulmonary transvalvular pressure gradient was 1 5 5 ± 3 4 mmHg All children survived and had no significant complications After a month pulmonary transvalvular pressure was 16 1 ± 3 3 mmHg Conclusions Echocardiography plays an important role in percutaneous balloon pulmonary valvuloplasty for children with congenital pulmonary valve stenosis As a non-x ray guided way it has advantages in preoperative screening of patients intraoperative real-time monitoring and postoperative assessment of efficacy The key sections of echocardiography for intraoperative monitoring are four-chamber and aortic short axis view.
