Abstract
Introduction
Untreated atrial septal defect (ASD) leads to various complications. These complications can be modified to a variable extent after closure of the defect, depending upon the age at the time of closure. While some patients get the total benefit of ASD closure, others are better left alone than undergo closure.
Purpose
We aimed to evaluate how the closure of ASD modifies the cardiopulmonary status during long follow up in different age groups.
Material and methods
Our study included 224 patients operated in last 20 years. They were divided into three age groups, viz. less than 20 years, 20 to 40 years, and more than 40 years. The clinical and investigative data about each patient’s preoperative cardiopulmonary status was compared with postoperative status using appropriate statistical method.
Results
Prevalence of arrhythmia and pulmonary artery hypertension (PAH) was predominant in advanced age group. Each of these showed favorable improvement after surgical closure; however, the effect was more pronounced in younger age groups. Persistence or new onset arrhythmia was seen in older patients; the trend however was not significant. There was a significant positive correlation between arrhythmia and PAH grade. Right ventricular remodeling in follow up was significant in patients more than 20 years of age. The New York Heart Association (NYHA) functional class also showed a significant improvement to better class in all age groups.
Conclusion
We conclude that definite morbidity in older patients is a strong argument favoring surgical closure early in life. In the older age group, hemodynamic benefits are much less pronounced and should be taken into account before surgical treatment is advised.
