Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Congenital heart conditions, including congenitally abnormal or fused heart valves like bicuspid aortic valves, are well-supported by genetic and familial studies to have a strong hereditary component.

The analysis

The retrieved literature consistently supports the hereditary and multifactorial etiology of congenital heart diseases and specific valve abnormalities like bicuspid aortic valves or valvular stenosis. Multiple papers (0, 1, 8) point to genetic inheritance patterns and pathway mutations. None of the papers refute the claim.
