BRAF and familial atrioventricular septal defect: In a large cohort of 165 ECD patients, Cohen-Aubart et al described a strongly positive correlation between the presence of BRAF mutation and detection of a right atrial pseudotumor (95% CI, 4.87–44.97, P < .0001).[11] On the other hand, they did not observe BRAF mutation to correlate with pericardial involvement, coated aorta or other non-coronary vascular involvement.
