Abstract

The secundum type of atrial septal defect (ASD) is a common congenital cardiac anomaly. Transcatheter closure of the defect is the preferable therapeutic approach to avoid potential future complications. This work extends the data collected so far regarding the electrocardiographic, morphologic, hemodynamic, and mechanical changes following the procedure. From April 2002 to October 2003, 42 consecutive patients underwent successful transcatheter closure of secundum type ASD. They were sampled for different parameters by transthoracic echocardiography before the procedure and at three different points over the next 4 years, and analyzed in two age groups: children and adults. The dimensions of the chambers normalized throughout the study period. Abnormal movement of the interventricular septum normalized mostly during the first month, but its thickness increased gradually to normal levels during the 4 years of the study. High elevated pulmonary artery pressure values began declining to near normal levels from the second month following the procedure. The stroke volume and the right bundle branch block pattern improved throughout the study period. Transcatheter ASD closure is followed by morphologic, conductive, and hemodynamic c...Continue Reading

Birth Defects

Birth defects encompass structural and functional alterations that occur during embryonic or fetal development and are present since birth. The cause may be genetic, environmental or unknown and can result in physical and/or mental impairment. Here is the latest research on birth defects.
