Analysis of clinical and candidate genetic risk factors for postoperative atrial tachycardia after congenital heart surgery in infants

AT occurs in 15% of infants after CHD surgery and is associated with increased morbidity and mortality. Risk factors include use of 2 or more inotropes, neonatal age, and higher surgical complexity score. We observed no association between common genetic variants in PITX2 and IL6 and AT in infants after CHD surgery.
