Abstract

Assess impact of malattached septum primum (MASP) on transcatheter closure of interatrial communications. Large defect size and deficient rims have been described as predictors for complications and unsuccessful device placement in closure of interatrial communications. MASP is an underappreciated morphologic atrial septal variation whose prevalence in isolated atrial communications and its influence on percutaneous device closure has not been systematically assessed. We retrospectively evaluated echocardiographic data of 328 patients scheduled for percutaneous secundum atrial septal defect (ASD) and patent foramen ovale (PFO) closure between January 2006 and January 2013. In ASD patients, defect size was measured by balloon stretch diameter while the length of the surrounding rims was measured in standard transthoracic and transesophageal views. Furthermore, the distance between septum primum and septum secundum as it attaches to the left atrial roof was evaluated in both, ASD and PFO patients. Septal anatomy of patients with procedural failure was compared to the anatomy of patients in whom the procedure was successful. Transcatheter defect closure was successful in 131 (92.3%) of 142 ASD patients (32.3 years ± 24.7 years) an...Continue Reading

Autism

Autism spectrum disorder is associated with challenges with social skills, repetitive behaviors, and often accompanied by sensory sensitivities and medical issues. Here is the latest research on autism.
