Abstract:
Objective To retrospectively analyze echocardiography findings and left hearst function in patients with patent ductus arteriosus (PDA) after transcatheter closure. Methods 28 patients admitted between January 2012 and December 2012 in our hospital for PDA transcatheter closure were included. Assessment of cardiac structure, hemodynamics and cardiac function parameters during preoperation and in postoperation 3 days, 1 month and 6 months were studied. Results Statistical significant difference was found at 3 days, 1 month and 6 months postoperation when compared with pre-operation in terms of left atrial diameter, left ventricular end-diastolic diameter, left ventricular end systolic diameter and other doppler measurements ( all P < 0. 05 ) . Six-minute walk test ( 6MWT) tolerance improved when compared to preoperation level (P < 0. 05). Better improvement in LVEF and LVES was observed in patients age ≤14 years old when compared to patients > 14 years old after operation ( P < 0. 05 ) . Conclusions Transcatheter closure of PDA can improve cardiac function and correct early hemodynamic abnormalities patients in younger age group show more benefit from the procedure.
