An autopsied case of quadrivalvular heart disease was described, in which pulmonary regurgitation due to possible bicuspid valve was predominant and tricuspid stenosis, mitral stenosis, and aortic stenosis with insufficiency coexisted. The patient was 47, and finally 53 years old female with long-term history of cough due to bronchial compression by the enormously dilated pulmonary artery. Clinical examination revealed massive pulmonary regurgitation, which was further substantiated by right heart catheterization and cineangiocardiography. The phonocardiograms and the reference tracings suggested the co-existence of tricuspid stenosis, aortic stenosis with regurgitation and mitral stenosis. Cardiac catheterization, intracardiac phonocardiography and angiocardiography also favored to the diagnosis of organic tricuspid stenosis. However, the ignorance of the presence of such an unusual combination misled to the precise antemortem diagnosis.Discussion was made on the rarity of quadrivalvular heart disease, and the pathogenesis of this unusual pulmonary regurgitation was analyzed based on the autopsy finding and the history as well as the clinical manifestation. Finally, combination of the murmurs of organic and relative tricuspid stenosis was presented to explain the acoustical findings of the present case.
