Left ventricular size and function after percutaneous closure of patent ductus arteriosus in Chinese adults

Evaluation of Cardiac Function Characteristics after Patent Ductus Arteriosus Closure in Children and Adults by Echocardiographic Data

This study was to investigate the value of echocardiographic data in assessing changes in cardiac function before and after transcatheter closure in children and adult patients with patent ductus arteriosus (PDA). In this study, 150 patients with isolated PDA treated by cardiac catheterization and transcatheter closure were selected as the study sample. Real-time color Doppler echocardiography was used both after and after operation. The results showed that the left ventricle returned to normal in 75 patients one day after operation, with an average age of 10.95 ± 3.27 years; the left ventricle did not return to normal in 10 patients 360 days after operation, with an average age of 64.31 ± 7.05 years. Left ventricular end diastolic volume index (LVEDVI) and left ventricular end systolic volume index (LVESVI) of patients decreased significantly one day after operation and remained at 51.95 ± 9.55 mL/m2 and 20.36 ± 8.11 mL/m-2, respectively. In summary, echocardiographic data have a high reference value in assessing cardiac function characteristics in children and adult patients with PDA and are worthy of further promotion.

Cardiac Reverse Remodeling After Transcatheter Patent Ductus Arteriosus Closure in Adults

Whereas most patent ductus arteriosus (PDAs) are identified and treated in the childhood, and the long term outcome studies have approved the outstanding results (positive cardiac reverse remodeling) in these group of patients, the outcome of percutaneous PDA closure in adults is not comprehensible. The aim of this retrospective cohort study which consecutively recruited 121 adult patients (age >16 years) who underwent the transcatheter closure (TCC) of PDAs between 2012 and 2018 is, evaluation at least 1-year follow-up of adult patients after PDA closure and compare the hemodynamic and the cardiac reverse remodeling findings with the previous studies in adults and children.
