ABSTRACT
OBJECTIVE@#To investigate the outcomes of hybrid procedure in treating 10 infants/children with pulmonary stenosis under transesophageal echocardiographic guidance. @*METHODS@#Between September, 2009 and December, 2015, 10 infants/children underwent hybrid procedure of transthoracic balloon pulmonary valvuloplasty for pulmonary stenosis in the Second Xiangya Hospital, Central South University. The age, height and weight at the time of admission were 0.7-42 (14.8±15.8) months, 53-97 (74.8±16.3) cm, and 4-15.5 (9.3±4.1) kg, respectively. Atrial septal defect, patent foramen ovale, patent ductus arteriosus, muscular ventricular septal defect, persistent left superior vena cava and tricuspid regurgitation were found in 2, 6, 1, 2, 1 and 5 cases, respectively. @*RESULTS@#After the operation, all patients were sent into ICU. The mean duration mechanical ventilation, ICU stay and hospitalization were 0.5-41(6.8±12.3) h, 2-85 (31.1±22.8) h, and 6-20 (11.4±5.1) d, respectively. Postoperative transvalvular pressure gradient reduced to 16-45 (31.1±9.8) mmHg, which was decreased significantly compared with that in preoperative (P<0.001). There was no death during hospitalization and follow-up. @*CONCLUSION@#Hybrid procedure of transthoracic balloon pulmonary valvuloplasty for pulmonary stenosis under transesophageal echocardiographic guidance is a safe and effective treatment.
