Transcatheter Atrial Septal Defect Device Closure - A 2.5 Years Single Center Study

Abstract

Background: Atrial septal communications account for approximately 6-10% of congenital heart defects, with an incidence of 1 in 1,500 live births. The atrial septal defect (ASD) is among the most common acyanotic congenital cardiac lesions, occurring in 0.1% of births and accounting for 30-40% of clinically important intracardiac shunts.Transcatheter device closure is advised for all symptomatic patients and also for asymptomatic patients with a Qp: Qs ratio of at least 2:1 or those with right ventricular enlargement. The timing for elective closure is usually after the 1st yr and before entry into school. Closure carried out at open heart surgery is associated with a mortality rate of <1%. Repair is preferred during early childhood because surgical mortality and morbidity are significantly greater in adulthood. Aim of Study:Is to evaluate 2.5 years experience in transcatheter device closure of secundum atrial septal defect at
