Abstract We conducted this prospective study including fifty patients presented electively for trans-catheter ASD device closure between August 2016 and September 2017. Thorough history taking and full general and local cardiac examination were done to all patients. Patients were assessed by full transthoracic echocardiography; 3D assessment of the ASD was done either by TTE or TEE according to the body weight of the patient with measuring defect area and circumference. The main findings of our study were: • All RV and RA dimensions significantly decreased, free and global RV strain significantly decreased and LV global circular strain significantly increased 24 hours post intervention. • ASD diameters measured in different conventional views in TTE and maximum 2D TEE diameter showed a strong positive correlation that was statistically significant when compared to the 3D derived dimensions. • We had 86% successful procedures for our patients enrolled for device closure. • ASD 3D imaging derived area and circumference measurements showed strong positive correlation that was statistically significant when compared to the finally used device waist and circumference. We could propose a new modality for device size selection based on regression analysis equations. |
