Mortality outcome of surgically treated atrial septal defects.
Comparative mortality in this abstract shows that surgical repair of an atrial septal defect (ASD) confers a survival advantage beyond that expected for the study population. Determinates of expected mortality and mean q' include the table selected, zero-time age and annual age, and sex distribution of the cohort. Each has an independent effect on mortality ratios and excess death rates. Confounding variables such as participant selection within the study cohort affect the outcome. Despite the multiple, methodologic variables in this abstract, individuals having surgical repair of an ASD appear to have low mortality.
