[A case of two-chambered right ventricle complicating severe cyanosis due to tricuspid regurgitation and patent foramen ovale]. A 63-year-old female of two-chambered right ventricle (TCRV) associated with tricuspid regurgitation (TR), patent foramen ovale (PFO) and small ventricular septal defect (VSD) underwent corrective surgery successfully. She suffered severe heart failure and cyanosis with 47.7% of right-to-left shunt through PFO. The VSD was so small that no significant shunt was shown in catheterization data. Operative findings suggested that TR was caused by elongation of the chorda as a consequence of long-term pressure load of right ventricular inflow chamber. Among reported cases of TCRV, the present case is the oldest one who underwent corrective surgery successfully.
