Echocardiographic Evaluation of Changes in Cardiac Hemodynamics, Loading Conditions and Atrial Function After Transcatheter Closure of Atrial Septal Defect

Abstract

Atrial septal defects account for approximately 10% of all congenital heart lesions. Two-dimensional echocardiography has been used as the modality of choice for diagnosis and adequate visualization of ASD. In a patient with ASD and right heart enlargement, closure of defect is recommended for the prevention of RV failure, paradoxical emboli and atrial arrhythmias Our study included 30 patients, referred for percutaneous closure of atrial septal defect (ASD), at Ain Shams University hospital, cardiology department, from June 2017 to October 2018 This study aimed to evaluate the changes in cardiac hemodynamics, loading conditions and atrial function, after percutaneous closure of atrial septal defect. All patients were subjected to adequate history taking, proper physical examination. The study included 15 pediatric patients (50% of study population) and 15 adult patients. Patient's age ranged from 3 to 55 years with mean of 16.45 ± 14.23 years. The study included 11 males (36.7%) and 19 females (63.3%). We evaluated the size, shape, and location of the defect and the relationship of the defect to its surrounding structures.
