Objective The objective of this study was to assess the feasibility percutaneous balloon pulmonary valvuloplasty (PBPV) under echocardiographic guidance only. Setting PBPV has become preferred choice for valve stenosis (PS). We report first-in-human successful only echocardiography isolated PS. Methods From March 2013 December 2014, 34 patients with congenital PS underwent as imaging modality in ordinary operation room or catheter lab. Outpatient follow-up including chest radiography, electrocardiography, and transthoracic (TTE) conducted at 1, 3, 6, 12 months. Results All successfully without radiation contrast agent. pulmonic transvalvular pressure gradient dropped from 62.8 ± 10.1 mm Hg 14.7 4.2 measured on catheterization (P < .05). diameter/pulmonary annulus diameter ratio 1.34 0.07. Slight regurgitation occurred five mild one patients. TTE months after procedure 14.1 4.6 Hg. No pericardial effusion peripheral vascular complications occurred. Conclusion This demonstrated that can be performed appears safe effective while avoiding agent use.
