Richard Lower, in 1669, first described the tubercle that now bears his name, calling it the intervenous tubercle located between the fossa ovalis and the superior vena cava. The aim of the study was to confirm the existence of the tubercle as described initially by Lower, adding details of its location, dimensions, and prevalence.
