Background: Congenital heart defects affect roughly 1 in 150 people and are often associated with right ventricular outflow tract (RVOT) dysfunction. The aim of the study was to evaluate the echocardiographic changes within the right ventricle following percutaneous pulmonary valve implantation (PPVI).
Methods: The echocardiographic data of 57 patients who had pulmonary valve stenosis and/or regurgitation and had undergone PPVI treatment and completed at least 1 year of regular follow-up at the Prince Sultan Cardiac Center from January 2012 to December 2015 were analyzed at the baseline level (before PPVI) and at 6 and 12 months following the PPVI treatment. Pulmonary insufficiency was graded from 0 to 4 based on severity: 0, none; 1, trivial; 2, mild; 3, moderate; 4, severe/free).
Results: There was a significant reduction in the RVOT gradient. At baseline, 95% of the subjects demonstrated pulmonary insufficiency (grades 2-4); at 12 months, 28% had decreased pulmonary insufficiency and 72% had limited to no pulmonary regurgitation. Other parameters, including right ventricular volumes, fractional area change, and the tricuspid regurgitant jet width/body surface area, did not demonstrate any significant change. Early follow-up echocardiographic data demonstrated persistent improvement in the RVOT gradient and pulmonary regurgitation level over the 1-year follow-up.
Conclusion: PPVI was seen to ameliorate RVOT dysfunction in most subjects.
