Background:: The most common congenital heart disease is atrial septal defect (ASD) which occurs in 1 per 1,500 childbirth. The secundum type ASD is the most common type of ASD. These defects can be promptly corrected by surgery if the indications are met with very low mortality and .morbidity.
Method: Retrospective Descriptive Review of all adult patients diagnosed with atrial septal defect who underwent ASD closure from January 2008 to July 2012. Outcomes including all-cause mortality, composite outcomes of death and complications after surgery were noted and analyzed.
Results: Results showed that ASD is seen more commonly in females than males, mean age for surgical closure is 32 +10yrs old. The most common presentation is easy fatigability (55.2%) with right ventricle (RV) and right atrial (RA) enlargement on chest x-ray (CXR) and 2-Dimensional echocardiography (2DED). Most of the patients who underwent surgery have normal BP, heart rate and no failure symptoms on admission. The success rate for surgical closure at the Philippine Heart Center (PHC) is 96% while 19.3% had complications. Females have more successful outcome after surgery which is 98% (149 out 152) as compared with males which is 91% (61 out of 67) Reasons for re-admission include arrhythmia, pericardial effusion and pulmonary congestion.
Conclusion: ASD surgical closure has a good success rate at PHC. Severity of pulmonary hypertension prior to surgery increases the rate of complications and poor outcome. Female gender has a better prognosis after surgery (98% vs. 91%) with a p value of 0.025.
