A rare congenital tricuspid malformation characterized by narrowing of the tricuspid valve orifice due to congenital valve anomalies, such as incompletely developed leaflets, shortened and malformed chordae tendineae, small annulus, and/or abnormal number and size of papillary muscles, resulting in right ventricular inflow obstruction. Clinical presentation depends on the degree of stenosis, as well as the presence or absence of additional cardiac anomalies, and includes easy fatigability, swelling of the lower limbs, and hepatomegaly, among others.
